{{#Wiki_filter:SEABROOK STATION Fire Protection of Safe Shutdown Capability (10CFR50, Appendix R) Revision 1 4 SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Introduction Rev. 5Section 1 Page 1-1 INTRODUCTION General Design Criterion 3, "Fire Protection," of Appendix A, "General Design Criteria for Nuclear Power Plants," to 10 CF R Part 50" Licensing of Producti on and Utilizatio n Facilities" requires that structures, systems and components important to safety shall be designed and located to minimize, consistent with other safety requirements, the probability and effects of fires. Appendix R, "Fire Protection Program for Nuclear Power Facilities Opera ting Prior to January 1, 1979" to 10 CFR Part 50 was issued on Novemb er 19, 1980 (45 FR 76602). Paragraph III.G, "Fire Protection of Safe Shutdow n Capability," requires that fire damage be limited so that: a. One train of systems necessary to achieve and maintain hot shutdown conditions from either the control room or emergenc y control station(s) is free of fire damage; and b. Systems necessary to achieve and maintain cold shutdown from either the control room or emergency control station(s) can be repaired within 72 hours. This requires each licensee to assess those areas of the plant"....where cables or equipment, including associated non-safety circuits that could prevent operation or cause maloperation due to hot shorts, open circuits, or shorts to ground of redundant trains of systems necessary to achieve and maintain hot shutdown conditions are located in the same fire area..." The regulation establishes separation requirements for areas outside of primary containment and inside noninerted containment. Appendix R, paragraph III.L, "Alternative and Dedicated Shutdown Capability," establishes the following performance goals for the shutdown functions: a. The reactivity control function shall be capable of achieving and maintaining cold shutdown reactivity conditions. b. The reactor coolant makeup function shall be capable of maintaining the reactor coolant level within level i ndication in the pressurizer. c. The reactor heat removal function shall be capable of achieving and maintaining decay heat removal. d. The process monitoring function shall be capable of providing di rect readings of the process variables necessary to perform and control the above functions. e. The supporting functions shall be cap able of providing process cooling, lubrication, etc., necessary to permit operation of the equipment used for Safe Shutdown functions. Branch Technical Position CMEB 9.5-1 "Guidelines for Fire Protection for Nuclear Power Plants," Rev. 2, July 1981 reiterates the above requirements in Section C.5.b and C.5.c. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Introduction Rev. 5Section 1 Page 1-2 By letters dated March 16, 1981 (from R.L. Tedesco to W.C. Tallman) and September 30, 1981 (from D.G. Eisenhut to W.C. Tallman) the Nuclear Regulatory Commission (NRC) transmitted "Request for Additional Information, Seabrook Station, Units 1 & 2, Fire Protection Program, Power System." This document requested New Hampshire Yankee (NHY) to provide information relative to the equipment and cabling required to achieve and maintain hot and/or cold shutdown. By letter dated July 27, 1982 (from F.J. Miraglia to W.C. Tallman) the NRC transmitted Auxiliary System Branch RAI's. By letter of May 15, 1981 (SBN-160), NHY committed itself to undertaking a comprehensive program to address the concerns identified in the NRC letters. This report and appendix detail the program a nd the analyses and evaluations emanating from it. The "Report" is comprised of the following: 1. An "Introduction" section.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Report Preparation Rev. 13 Section 2 Page 2-1 REPORT PREPARATION/MAINTENANCE To establish a methodical course of action and provide guidance to the various organizations required to support the initial development of the Safe Shutdown Capability program, UE&C procedure TP -2 (NHY Procedure 38160) titled "Procedure for Review and Report Preparation for 10 CFR Part 50 Appendix R, Fire Protection of Safe Shutdown Capability " was prepared. The salient points of this procedure are as described in Sections 2.1 to 2.8. As modifications are implemented to the plant, the effect of these modifications to this report must be evaluated. The evaluation process is as described in Section 2.9. 2.1 DETERMINATION OF FIRE AREAS/ZONES The fire areas/zones are as delineated in "Fire Protection Program Evaluation and Comparison to Branch Technical Position APCSB 9.5 -1, Appendix A " or as determined by the Responsible Engineer. 2.2 DETERMINATION OF SAFE SHUTDOWN SYSTEMS The Safe Shutdown systems were determined by considering the minimum performance goals established in Appendix R, Paragraph III.L.2, and utilizing the following sources for guidance: 2.2.1 Final Safety Analysis Report - Seabrook Station 2.2.2 Fire Protection Program Evaluation and Comparison to Branch Technical Position APCSB 9.5 -1, Appendix A 2.2.3 Station Operating Procedure No. OS1200.01 "Safe Shutdown and Cooldown from the Main Control Room " 2.2.4 Station Operating Procedure No. OS1200.02 "Safe Shutdown and Cooldown from the Remote Safe Shutdown Facilities " 2.2.5 United Engineers & Constructors Inc. Engineering 2.2.6 Yankee Atomic Electric Co. Engineering 2.2.7 New Hampshire Yankee Engineering

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Report Preparation Rev. 13 Section 2 Page 2-2 2.3 DETERMINATION OF SAFE SHUTDOWN EQUIPMENT The minimum equipment necessary to perform the Safe Shutdown function was determined by utilizing the following sources: 2.3.1 Final Safety Analysis Report - Seabrook Station 2.3.2 Fire Protection Program Evaluation and Comparison to Branch Technical Position APCSB 9.5 -1, Appendix A 2.3.3 Station Operating Procedure No. OS1200.01 "Safe Shutdown and Cooldown from the Main Control Room " 2.3.4 Station Operating Procedure No. OS1200.02 "Safe Shutdown from the Remote Safe Shutdown Facilities " 2.3.5 Piping and Instrumentation (P&I) Diagrams 2.3.6 United Engineers & Constructors Inc. Engineering 2.3.7 Yankee Atomic Electric Co. Engineering 2.3.8 New Hampshire Yankee Engineering Sets of P&I Diagrams and One -Line Diagrams were marked to indicate hot standby equipment and cold shutdown equipment for main control room shutdown and remote safe shutdown. Train A equipment was marked in red, and Train B equipment was marked in green. Photographs of typical marked P&I Diagrams are contained in Appendix Section I. 2.4 DETERMINATION OF SAFE SHUTDOWN CABLES Considering the equipment defined and utilizing their related electrical schematic diagrams and cable schematics, the cables required for Safe Shutdown were determined. The raceways through which these cables were routed were determined; and then their associated fire area/zone(s) were determined. To document the review, the "10 CFR 50 - Appendix R, Safe Shutdown Equipment List" was prepared from data gathered in this review. Copies of typical schematic diagrams and cable schematics are contained in Appendix Section II. Copies of the safe shutdown equipment lists are contained in Appendix Section III.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Report Preparation Rev. 13 Section 2 Page 2-3 The equipment required for fire safe shutdown can be divided into supporting equipment and supported equipment. For example, CC -TE-2197 is supporting equipment for CC pump trip and CC-P-11A/C are the corresponding supported equipment. Supported equipment tag numbers are typically listed in the Appendix III Equipment Tables - "Equipment Id No. " column and represent the major components used to perform each safe shutdown function. Supporting equipment tag numbers are typically not listed in the "Equipment Id No. " column but should be listed in the "Supporting Control and Instrumentation Equipment " columns. The following guidance should be used for lisiting supported and supporting equipment tag numbers in the Appendix R Report Section 3 Tabulations and for assigning the descriptions for CASP cables. The tag number for supporting equipment should be listed in the tabulation for the fire zone/area in which the equipment is located with an "X" in the equipment column and an "X" in the cable column. For other fire zones/areas which contain just the cable for the supporting equipment, the cable should be accounted for with an "X" in the cable column using the tag number of the supported equipment. The safe shutdown analysis for each fire zone/area should discuss the impact of fire damage to the supporting equipment cables and equipment in terms of the impact on operation of the supported equipment. The cable "description " in CASP for supporting equipment cables should be the support ed equipment tag number. Note that this specific guidance was added to the Report in 2013 to address future Report changes but was typically applied in the past. 2.5 COMPUTER INPUT AND REPORTS The following data were input to UE&C 's "NRC Emergency Shutdown Program NRCESP " Program No. EL -130: a. Listing of Raceways and their Associated Fire Zones

b. Listing of Cables (from Safe Shutdown Equipment Lists)

The following output reports were generated using the NRC Emergency Shutdown Programs:

c. Listing of Fire Areas/Zones

d. Safe Shutdown Cables using CASP A Format

e. Safe Shutdown Raceways and Associated Cables by Fire Zone

f. Safe Shutdown Raceways and Cables

g. Cables with Associated Fire Zones Copies of the input data and output reports were contained in Appendix Section V.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Report Preparation Rev. 13 Section 2 Page 2-4 2.6 DETERMINATION OF SAFE SHUTDOWN RACEWAYS Utilizing the "Safe Shutdown Raceways and Associated Cables by Fire Zone " computer report, a set of raceway arrangement drawings was marked as follows: 2.6.1 Train A raceways, boxes, and termination equipment were marked in red. 2.6.2 Train B raceways, boxes, and terminating equipment were marked in green. 2.6.3 Equipment which is manually operated or disabled was marked in orange. A "D" was placed beside equipment to be disabled. An "M" was placed beside equipment needed to be manually operated. 2.6.4 Rated fire walls and barriers were marked in black. Photographs of typical marked raceway arrangement drawings are contained in Appendix Section IV. 2.7 ANALYSIS OF RACEWAYS AND EQUIPMENT TO SATISFY APPENDIX R REQUIREMENTS 2.7.1 Each fire area/zone that contained Safe Shutdown equipment or cables was reviewed to determine if Appendix R, Paragraph III.G.2 separation requirements were satisfied. 2.7.2 If the Appendix R requirements were not satisfied, further analysis was performed to determine the effects of a hot short circuit, short circuit, open circuit, ground or other equipment failure. 2.7.3 If the Safe Shutdown function was affected by a hot short circuit, short circuit, open circuit, ground or other equipment failure, then the following analysis to satisfy the Appendix R requirements was provided: 2.7.3.1 Analysis which documented that the in situ and transient combustibles were insufficient to cause a fire which affected the redundant trains of equipment and cables. 2.7.3.2 A three-hour fire barrier or a one-hour barrier and sprinklers between the redundant equipment or cables. 2.7.3.3 Rerouted the redundant cable out of the fire area/zones, or provided twenty feet of separation and sprinklers in the area.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Report Preparation Rev. 13 Section 2 Page 2-5 2.7.3.4 Provided an alternative or dedicated safe shutdown equipment or system (See Section 3.3 and 3.4). 2.7.3.5 Requested a deviation from the 10 CFR 50, Appendix R requirements based on the combustibles in the fire area/zone, the spatial separation and the protective measures provided.

(See Section 3.7). 2.8 HIGH-LOW PRESSURE INTERFACES A list was prepared of the high

-low pressure interfaces and the lines with two or more electrically operated valves which could open and potentially cause a LOCA. A review was performed in the same manner as discussed in Section 2.4 and 2.5 utilizing this list. An analysis and evaluation were then performed.

(See Section 3.5) 2.9 MODIFICATION EVALUATION As plant modifications are implemented, their effect on the analysis contained in this report must be evaluated to ensure that the safe shutdown capability in the event of a fire is maintained. This evaluation will consider the UFSAR, this Appendix R Report, Supporting Documentation and the latest issue of design documents. If necessary, appropriate markups of documents will be included in the design change package to reflect any change in the Appendix R safe shutdown analysis.

The UE&C computer programs described in Section 2.5 are no longer available. New computer programs were written to produce the following reports to support the analysis contained in this report and evaluation of modifications:

a. List of Areas/Zones

b. List of Raceways and Associated Fire Zones

c. List of Cables w/Event Indicators

d. Safe Shutdown Raceways and Associated Cables by Fire Zone

e. Safe Shutdown Raceways and Cables

f. Cables with Associated Fire Zones Copies of these reports are contained in Appendix R supporting documentation.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 10 Section 3.1 Page 3.1-1 SAFE SHUTDOWN CAPABILITY 3.1 DISCUSSION OF BASES AND POSITIONS 3.1.1 General 10 CFR Part 50 Appendix R, Paragraph III.G.1 requires that fire damage be limited so that:

a. One train of systems necessary to achieve and maintain hot standby condition from either the control room or emergency control station(s) is free of fire damage; and

b. Systems necessary to achieve and maintain cold shutdown from either the control room or emergency control station(s) can be repaired within 72 hours. Based on requiremen t "a" above, the design basis of Seabrook Station is that one train of systems necessary to achieve and maintain hot standby from the control room or the emergency control stations (hereafter designated the remote safe shutdown facilities) is free of fire damage. Under this basis, Appendix R, Paragraph III.G.2 and III.G.3 will apply to the safe shutdown paths controlled from the main control room or the remote safe shutdown facilities. Any deviations from the III.G.2 and III.G.3 criteria will be with respect to the main control room or the remote safe shutdown facilities and is addressed in Sections 3.2.7, 3.3.9, 3.4.3 and in the List of Deviations Section 3.7 of this report. For fires in some areas of plant, alternative shutdown capabilities are provided as discussed in Sections 3.3 and 3.4.

This Section defines the bases and positions utilized in determining and reviewing the shutdown capabilities that will satisfy the requirements of Paragraph III.G. These capabilities can be utilized to safely shut down the reactor in the event of a fire in any area/zone of the plant. 3.1.2 Safe Shutdown "Safe Shutdown " for purposes of the review is defined as a capability to bring the reactor from a 100 percent power operating condition to a "cold shutdown " condition. Included in this are conditions "hot standby, " "hot shutdown, " "cold shutdown, " and maintenance of "cold shutdown. " SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 10 Section 3.1 Page 3.1-2 The design basis event for safe shutdown is a postulated fire in a specific fire area/zone with or without the loss of offsite power (LOOP). This design basis was used for the original Appendix R Report preparation. The LOOP was assumed to occur whether the specific fire being analyzed caused it or not. The diesel generators (DGs) were analyzed to both automatically start and load, and not automatically start and load. An engineering evaluation prepared in 2007, documented that this was a conservative design basis since Appendix R does not require an arbitrary LOOP for non-alternate shutdown fire areas/zones (i.e., for shutdown control from the main control room). For future safe shutdown analyses, offsite power can be credited to remain available for

non-alternate shutdown fire areas/zones if the cables required to support offsite power are not damaged by the fire (i.e., an arbitrary LOOP need not be assumed). This approach provides greater analysis flexibility. No other design basis event (e.g. seismic or LOCA) is considered to occur coincident with the fire event. The safe shutdown functions shall assure the following:

a. No fuel clad damage. b. No rupture of any primary coolant boundary.

c. No rupture of containment boundary.

d. Reactor coolant system process variables shall be within those predicted for a loss of normal AC power.

e. Achievement of cold shutdown conditions within 72 hours and maintenance of cold shutdown conditions thereafter.

3.1.3 Redundancy

To assure a safe shutdown capability pre -fire, two redundant trains (Train A and Train B) of equipment are provided for each safe shutdown function. Each train contains a complete complement of the equipment, cabling, instrumentation and controls necessary to perform the safe shutdown functions. In several instances a single mechanical equipment is common to both trains (i.e., condensate storage tank, mechanical manual valves, piping, HVAC ducts, etc.). Single failure is not assumed to occur except to equipment that is damaged by the fire.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 10 Section 3.1 Page 3.1-3 3.1.4 Determination of Safe Shutdown Functions The safe shutdown functions are determined by considering the performance goals established in Appendix R, Paragraph III.L.2. The systems or portions of systems necessary to satisfy safe shutdown are subsequently determined. 3.1.5 Determination of Safe Shutdown Equipment Safe shutdown systems are the systems required to achieve the performance goals listed in Section 1. The equipment for these systems can be divided by function as Hot Standby (Reactor tripped and T -Avg above 350F) and Cold Shutdown (Reactor tripped/and cool down of the Reactor Coolant System T -Avg equal to or below 200F). The following criteria are used to determine the equipment required for safe shutdown:

a. The equipment is required to operate to permit a safe shutdown system to perform its safe shutdown function.

b. The equipment

's maloperation can prevent a safe shutdown system from performing the safe shutdown function.

c. The equipment is a process or electrical boundary for a safe shutdown system.

3.1.6 Safe Shutdown System Boundaries The safe shutdown system process boundaries are established by the following devices:

a. Normally closed manual valve

b. Check valve

c. Electrically operated safe shutdown valve

d. Root valve on small instrument lines to non

-safe shutdown instruments

e. Relief valve

f. Redundant valves on high

-low pressure boundaries

g. Boundary valve between a safe shutdown process line and a non

-Safe Shutdown process line which if it is an incorrect position will not affect the operation of the Safe Shutdown system.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 10 Section 3.1 Page 3.1-4 The safe shutdown electrical system boundaries are established by the following devices:

h. Isolation device (i.e., coordinated circuit breaker, fuse, transducer, etc.)

i. "Remote Local

" selector switch Cables isolated by "Remote-Local" selector switches or other isolation devices are not included in the review. 3.1.7 Manual Operator Actions Manual operator actions must satisfy the following considerations:

a. Sufficient manpower and time is available to perform all required manual actions.

b. There is accessibility to the equipment to perform the manual action either during or after the fire.

3.1.8 Spurious Operation The evaluation of the effects of spurious equipment operation on safe shutdown functions considers the effects of hot short circuits, short circuits, open circuits and grounds. The effects of hot short circuits are considered on the following:

a. Energized 120V ac grounded circuits

b. De-energized 120V ac grounded circuits

c. Energized 120V ac ungrounded circuits

d. Energized 125V dc ungrounded circuits Hot short circuits are not considered for disabled (tripped power supply) 3

-phase 480 Volt ac circuits, ungrounded 1 -phase 120 Volt ac circuits and ungrounded 125 Volt dc circuits as these would require multiple hot shorts in the correct sequence to cause a device to function. These are considered incredible events. The effects of short circuits, open circuits and grounds are considered for all circuits evaluated for spurious operation.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 10 Section 3.1 Page 3.1-5 The above discussion does not provide all of the criteria used for evaluating spurious component operations during the original Appendix R Report preparation. An engineering evaluation prepared in 2007 reviewed various Seabrook, NRC, and industry documents to re -create the circuit analysis methodology bases used for the fire safe shutdown analyses that was not included in the above discussion. The following documents the added methodology criteria. The analyses shall consider fire induced damage to any and all unprotected cables in the fire area/zone being analyzed. Each cable failure shall be considered individually, one -at-a-time, and the effects of any spurious operation(s) evaluated. If the effect is unacceptable (ex. loss of inventory), then operator actions, or other corrective actions (see Section 2.7), are specified to mitigate the effects of the spurious operation. If the effect is acceptable, then additional sequential cable failures and resultant spurious operations of same function components must also be considered (ex. spurious opening of other normally closed series valves in a potential diversion flow path). If their effects are unacceptable, then appropriate preventative/disabling operator actions (ex. open a circuit breaker) are specified to prevent the unacceptable condition. Mitigating and preventative/disabling actions that rely on electrical power, ex. MOV operation, can not credit components with unprotected cables in the fire area/zone being analyzed. The basis described in the previous paragraph is typically referred to in the industry as any-and-all, one-at-a-time. In addition, it will be assumed that the loss of function from fire damage to unprotected cables within a fire area cable will prevent the effected components from operating to support safe shutdown but any resulting state changes will be evaluated as spurious operations following the above criteria of one -at-a-time. Also, a protective device state change from a short circuit (open a fuse or trip a circuit breaker) will be considered a spurious operation and will be evaluated following the above criteria of one -at-a-time including any end component state changes, ex., loss of control power to a normally energized solenoid operated valve (SOV) would cause the SOV to change state as a spurious operation. For Seabrook, failure of an individual cable typically only causes spurious operation of one component although there are exceptions where one cable failure can cause spurious operation of multiple components.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 10 Section 3.1 Page 3.1-6 The complete circuit for each equipment tag typically consists of multiple cables routed through many fire zones. It is expected that applying the failure modes to some cables in a circuit may not actually result in a spurious operation of the corresponding equipment. However, it appears that the original safe shutdown analyses conservatively assumed that every cable failure would cause spurious operation of the supported component(s) since there was no evidence found in the original analyses of credit being taken for analyzing specific conductor interactions as the basis for concluding that there was no resulting spurious operation. For future safe shutdown analyses, it is acceptable to use circuit analysis to demonstrate that a fire -induced cable failure can not cause a spurious operation. These circuit analyses should be included in appropriate engineering documents. Operator actions to mitigate spurious component operation must meet the criteria provided in Section 3.1.7 on manpower, timing and accessibility considering the system effect of the corresponding spurious operation. Preventative/disabling operator actions should be documented in a procedure and be able to be completed in a reasonable time consistent with completion of time critical mitigating actions. Automatic signals can be credited if their circuits are included in the analysis to ensure that their cables are free of fire damage for the fire areas which credit the signals. Automatic signals with unprotected cables in a fire zone must be analyzed to fail to operate or spuriously operate because of fire-induced cable damage. The automatic signals must also be analyzed to operate as designed if the system conditions caused by the fire (ex. low level, high flow, loss of power, etc.) would initiate the automatic function to ensure that the automatic actuation is not detrimental to safe shutdown. The review assumes that all conductors within multi -conductor cables would short, open or ground due to a fire. Cable to cable interactions are not considered credible events because of the

thermoset cable insulation used at Seabrook Station. 3.1.9 Disabled (tripped power supply) Equipment To prevent spurious operations of valves and other equipment which are normally aligned in their safe shutdown position, the operators will trip the power supplies to these devices upon reaching the RSS facilities.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 10 Section 3.1 Page 3.1-7 3.1.10 Fire Areas The "Fire Protection Program Evaluation and Comparison to Branch Technical Position APCSB 9.5-1, Appendix A" report establishes fire areas and zones for purposes of fire detection and protection. Although these zones are satisfactory for fire detection and protection, they do not in all cases satisfy Appendix R requirements. To assure that the Appendix R separation requirements are satisfied, zones containing redundant equipment which do not satisfy the requirements are grouped and analyzed to provide assurance that safe shutdown can be achieved. An example of this is containment which has three zones: C -F-l-Z, C-F-2-Z and C-F-3-Z. As there is no 3 -hour rated barrier between zones, they have been considered as one fire area. The delineation of the fire areas and zones which have been combined into a fire area is in Section 3.2.7. 3.1.11 Emergency Lighting Emergency lighting units per Appendix R, Paragraph III J are provided with at least an 8 -hour battery powered supply or diesel generator backed essential lighting (See letter SBN -932, dated January 27, 1986, Deviation No. 10) in all areas needed for operation of safe shutdown equipment and in access and egress routes. In areas where actions are required after eight hours and actions are needed during a cooldown, 8 -hour battery powered supplied lights are not provided. Repairs per Appendix R III G.l.b, will be implemented to provide required illumination for required cooldown actions. 3.1.12 Repairs for Cold Shutdown For cold shutdown, the following equipment will require replacement of control fuses which will be available in the Train B switchgear room.

a. EAH-FN-31B b. RC-V87 c. RC-V88 d. RH-P-8B e. SI-V17 f. SI-V47 In the event that emergency bus EDE

-SWG-5 is not available, a temporary power connection will be provided from EDE -MCC-621 to the RC -V88 MCC cubicle.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 10 Section 3.1 Page 3.1-8 In the event that PCCW cooling is lost to containment due to loss of containment instrument air causing inboard PCCW isolation valve closure, IA -V530 will be manually opened via a pneumatic jumper to supply outside containment instrument air to containment instrument air to reopen the inboard PCCW isolation valves to reestablish PCCW cooling flow to support containment habitability.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-1 3.2 MAIN CONTROL ROOM SAFE SHUTDOWN 3.2.1 Main Control Room Safe Shutdown Locations Safe shutdown will be accomplished with control from the main control room (MCR), utilizing the safe shutdown equipment and depending on the location of the fire, a combination of the following locations:

a. Train A Switchgear Room

b. Train B Switchgear Room

c. Diesel Generator Room A

d. Diesel Generator Room B

e. Primary Auxiliary Building El. 25

'-0" Boric Acid Storage Tank Area

f. Primary Auxiliary Building El. 7

'-0" Charging Pump Rooms

g. Containment

h. Equipment Train A Vault (Vault #1)

i. Equipment Train B Vault (Vault #2)

j. Mechanical Penetration Area

k. Emergency Feedwater Pump Building

l. Condensate Storage Tank

m. Control Room HVAC Equipment and Duct Area

n. Non-Essential Switchgear Room

o. Turbine Building Actions from the various areas would be of the following types: manual valve actuations, manual damper actuations, tripping of power supplies, opening of doors to provide air flow for cooling, realign power supplies, and/or manipulation of control switches.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-2 The term "prompt action " refers to an action taken after receipt of a valid fire alarm in the main control room. The term "expeditious action" or "expeditiously " refers to an action taken quickly upon entry into the applicable safe shutdown procedure. These type actions are considered to be completed prior to a spurious operation of the equipment operated by the prompt and expeditious

actions. Therefore, no associated timing calculation is required for these actions. 3.2.2 Safe Shutdown Functions for Hot Standby The following are PWR equipment necessary for hot standby: 3.2.2.1 Reactor Coolant (RC) Inventory and Pressure Control To compensate for miscellaneous RC system leakage, RC pump seal leakage and cooldown volume shrink, portions of the chemical and volume control (CS) system including centrifugal charging pumps, boric acid transfer pumps, and a borated water supply, either the refueling water storage tank (RWST) or the boric acid tanks (BAT) are used. The injection path to the RC system will be either through the seal injection flow path or the high head injection flow path. The preferred seal injection path requires that a flow control valve (CS -FCV-121) and that a minimum of two of the four seal injection valves (CS -V154, CS-V158, CS-V162 or CS -V166) be operable. Additionally, the normal charging flow path to the RC system is isolated. This can be accomplished by use of any one of three functionally redundant valves (CS -V142, CS-V143 or CS-HCV-182). Should the seal injection path not be operable, e.g., due to spurious closure of a flow path valve (CS -FCV-121) the high head injection flow path (SI -V138 or SI -V139) can be utilized initially to maintain hot standby by batch charging from the RWST to maintain pressurizer level. Should SI -V-138 or SI -V-139 spuriously open, the charging pump may have to be stopped to prevent overfill of the pressurizer. During cooldown as RC system pressure decreases, it is necessary to provide a flow restricted path to prevent charging pump cavitation. This is due to the limited flow capability from the BAT. If the high head injection path cannot be isolated at this time and/or if the flow controlled path through CS -FCV-121 is not operable, a capability is provided to manually align and throttle the charging pumps to the seal injection flow paths. The necessary operator actions and valve alignments are unique for each fire area where these flow paths are affected and are described in the analysis for each area. RC pump seal cooling is provided by a redundant thermal barrier cooling system. Should the redundant thermal barrier system not be available, the seals will be cooled by the seal injection capability. On a long term basis, seal injection will be restored. The reactor coolant pumps (RCPs) are stopped from the main control board. Circuit analysis shows that the RCPs can not spuriously restart due to fire -induced cable damage.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-3 The RC system pressure is controlled by use of a portion of the RC system which includes the pressurizer heaters (Group A and B) to increase pressure and the pressurizer power operated relief valves (PORV) which depressurize the RC system by discharging reactor coolant fluid to the pressurizer relief tank (PRT). Considering worst case scenarios for spurious actuation of affected equipment, the required times for operator actions regarding RC inventory and pressure control for safe shutdown from the main control room are provided below: Action Time Close PORV block valve Prompt Isolate letdown 15 minutes Swap charging pump suction from VCT to RWST 15.4 minutes. Should SI -V138, SI-V139, or CS -HCV-182 spuriously open, this action must be completed no later than 5.0 minutes following letdown line isolation. Trip RCPs 10 minutes Open a PORV to reduce pressurizer pressure in the event of spurious pressurizer heater operation or trip

<4 hours, prior to commencement of plant cooldown 3.2.2.2 Reactivity Control Reactivity for hot standby at normal operating temperature (not) is provided by insertion of the control rods. Reactivity conditions required for cooldown and maintaining cold shutdown are provided by a portion of the chemical and volume control (CS) system which includes a centrifugal charging pump taking suction from the BAT

's either utilizing the gravity flow path or the boric acid transfer pumps. During cooldown, the borated water source must be the BAT volume until exp ended to at least the point that the volume injected or a boron sample demonstrates that sufficient shutdown margin for cold shutdown has been achieved, at which time the RWST would be aligned. If gravity feed from the BAT is used, the RWST must be isolated. Considering worst case scenarios for spurious actuation of affected equipment, the required times for operator actions regarding reactivity control for safe shutdown from the main control room are provided below: Action Time Trip the Reactor Expeditiously Provide borated water from the BATs, via boric acid transfer pump or gravity feed

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-5 3.2.2.3 Decay Heat Removal The reactor coolant (RC) system temperature is controlled by use of portions of the feedwater (FW) system and the main steam (MS) system. The main steam safety/relief valves will maintain a heat dump capability. The steam generator water inventory is controlled by operating the motor driven emergency feedwater pump, the start -up feedwater pump, and associated valves. Inventory for the emergency feedwater is from the condensate storage tank. Long term water capability exists using a temporary connection between the suction of the turbine driven emergency feed pump and the fire protection system but is not required to meet Appendix R requirement. This temporary connection back feeds to the CST which supplies water to the startup feedwater pump and the motor driven emergency feedwater pump. To assure main steam system integrity the MSIV 's and MSIV bypass valves are maintained closed. The MSIV bypass valves are normally locked closed and depowered with breakers locked open to preclude spurious opening. Decay heat transfer is made possible by natural convection flow in the RC system. Considering worst case scenarios for spurious actuation of affected equipment, the required times for operator actions regarding decay heat removal for safe shutdown from the main control room are provided below: Action Time Isolate the MSIVs Expeditiously following a reactor trip Place the mode selector switches for the ASDVs to the closed position Prompt Gain Control of excessive Emergency Feedwater Flow 20 minutes Start motor driven EFW pump or startup feedwater pump to preclude steam generator dry out - normal power operation 39 minutes Start motor driven EFW pump or startup feedwater pump to preclude steam generator dry out - low power operation 75 minutes Time to bypass the startup feed pump low suction trip 4 hours SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-6 Action Time Time allotted for operator actions to preclude emptying CO tank to accommodate RHR Cut -in, and ultimately achieve cold safe shutdown within 72 hours 9 hours; 4 hours at hot standby plus

General Area Analysis The following protective measures are inherent in the existing containment design:

a. The significant in situ combustibles are limited to the reactor coolant pump lubricating oil, hydraulic snubbers, cables in trays, and EPDM rubber (debris interceptor trim).

b. An oil collection system is provided for the reactor coolant pumps.

c. Each hydraulic snubber contains 3.5 gallons of a high flash point, high auto ignition point silicon

-based hydraulic fluid. The snubbers are designed to withstand an SSE without failure. Even if leaks were to develop, studies performed at Factory Mutual Research Corporation have shown that a heat flux of 16 kW/M2 is necessary to ignite a high flash point hydraulic fluid similar to the silicon based fluid. It would require the introduction of a transient combustible to containment to provide this heat flux.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-25 d. Containment is inaccessible during normal operation with the exception of operator tours. Because of this, transient combustibles are not considered as a fire hazard. This absence of transient combustibles removes the ignition source for the cables, the hydraulic fluid, and the EPDM rubber.

e. Prior to plant start

-up administrative controls will assure the removal of transient combustibles which could be brought into containment during plant shutdowns.

f. Charcoal filter CAH

-F-8 has an early fire detection system internal to the filter.

2. System Analysis

a. Containment Structure Cooling Units CAH

-AC-1A through 1F (Fans CAH-FN-1A through 1F, Speed Changers CAH -JV3-43 through CAH -JV8-43 and CC Flow Switches CC -FISL 2122 through CC -FISL-2224) Cables for the redundant cooling unit fans, speed changers and flow switches are routed through trays and conduits from the penetration where they enter containment to the cooling units. The trays are separated by concrete floors except between Columns 2 and 4, Columns 5 and 6, Columns 7 and 8, Columns 12 and 13, Columns 14 and 15, and Columns 17 and 18 where there is grating. Between Columns 2 and 4, the Train B trays are a minimum of 12 ' above floor elevation ( -) 26'-0" and a maximum of 19 ' above floor elevation ( -) 26'-0". The Train A trays are a minimum of 11 ' above the grating elevation 0 '-0". There is a minimum of 18 ' of vertical separation between the redundant trays. Even if the redundant trays are affected by a fire, only two Train B and one Train A cooling unit could be affected, the other three cooling units would continue to be operable. Between Columns 5 and 6, the Train B trays are a minimum of 14' above floor elevation ( -) 26'-0" and a maximum of 19 ' above floor elevation ( -) 26'-0". The Train A trays are a minimum of 18 ' above the grating elevation 0 '-0". There is a minimum of 24 ' of vertical separation between the redundant trays. Even if the redundant trays were affected by a fire, only one Train A and one Train B cooling units could be affected; the other four cooling units would continue to be operable. Between Columns 7 and 8, only one Train A cooling units ' cables are routed. There are no Train B cooling units ' cables at this location.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-26 Between Columns 12 and 13, only one Train A and one Train B cooling units ' cables are routed. The other four cooling units would continue to be operable. Between Columns 14 and 15, the Train B trays are a minimum of 19 ' above floor elevation ( -) 26'-0" and a maximum of 21 ' above floor elevation ( -) 26'-0". The Train A trays are a minimum of 17 ' above the grating elevation 0 '-0". There is a minimum of 22 ' of vertical separation between the redundant trays. Even if the redundant trays were affected by a fire, the only two Train A and one Train B cooling unit could be affected. The other three cooling units would continue to be operable. Between Columns 17 and 18, the Train B trays are a minimum of 12 ' above floor elevation ( -) 26'-0" and a maximum of 19 ' above floor elevation ( -) 26'-0". The Train A trays are a minimum of 11 ' above the grating elevation 0 '-0". There is a minimum of 18 ' of vertical separation between the redundant trays. Even if the redundant trays were affected by a fire, only two Train A and one Train B cooling units could be affected; the other three cooling units would continue to be operable. A maximum of three containment structure cooling units (CAH) are needed to maintain habitability of the containment. This can be any combination of Train A and B units. At all points discussed above where Train A and B cables are run near each other without concrete floor separation, there is a minimum of 18 ' of vertical separation, with the Train B cables a minimum of 12 ' off the floor. This vertical separation, the height of the cable from the floor and the lack of combustibles provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. Additionally, a fire at any of these points would affect a maximum of three out of six units, leaving three to cool containment.

b. Thermal Barrier Pumps CC

-P-322A and CC -P-322B Cables for the redundant thermal barrier pumps are routed through trays and conduits from the penetration where they enter containment to the pumps at elevation ( -) 26'-0". The trays are separated by concrete floors except between Columns 17 and 18 where there is a grating. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-27 Between Columns 17 and 18, the Train B trays are a minimum of 12 ' above floor elevation ( -) 26'-0" and a maximum of 19 ' above floor elevation ( -) 26'-0". The Train A trays are a minimum of 11 ' above the grating elevation 0 '-0". There is a minimum of 18 ' of vertical separation between the redundant trays. The only in situ combustibles at this location are the cables in trays. The conduit to the Train A pump is routed such that there is a minimum of 6 ' horizontal separation from the Train B tray that contains the redundant cable. The conduit is run approximately 22 ' above elevation ( -) 26'-0" to the point that it drops down to the Train A pump. The pump is located 6 ' above elevation (-) 26'-0" between Columns 17 and 18. The Train A pump is separated from the tray containing the cable to the Train B pump by a horizontal distance of 6 ' and a vertical distance of 9 '. In addition there are two totally enclosed instrument trays below the Train B tray. Should the thermal barrier cooling be unavailable, the redundant seal injection cooling capability located in other plant fire areas will satisfy the safe shutdown requirements. The separation height of cable from the floor and lack of in situ combustibles provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. The redundant seal cooling satisfies the safe shutdown requirements.

c. Component Cooling Isolation Valves CC

-V57, CC-121, CC-V176, CC-V256 Cables for the redundant valves are routed through trays and conduits from the penetration where they enter containment to the valves on the west side of containment at elevation 4 '-0". The trays are separated by a concrete floor, except between Columns 17 and 18 and between Columns 14 and 15 where there is grating. Between Columns 17 and 18, the Train B trays are a minimum of 12 ' above floor elevation ( -) 26'-0" and a maximum of 19 ' above floor elevation ( -) 26'-0". The Train A trays are a minimum of 11 ' above the grating elevation 0 '-0". There is a minimum of 18 ' of vertical separation between the redundant trays. The only in situ combustibles at this location are the cables in the trays.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-28 Between Columns 14 and 15, the Train B trays are a minimum of 19 ' above floor elevation ( -) 26'-0" and a maximum of 21 ' above floor elevation ( -) 26'-0". The Train A trays are a minimum of 17 ' above the grating elevation 0 '-0". There is a minimum of 22 ' of vertical separation between the redundant trays. The only in situ combustibles at this location are the cables in the trays. The Train A valves CC -V57 and CC -V121 are located between Columns 14 and 15 approximately 4 ' above the grating elevation 0 '-0". The cables for the Train B valves CC -V176 and CC -V256 are routed in trays which are a minimum of 19 ' above floor elevation ( -) 26'-0". There is a minimum of 8 ' vertical separation between the Train B trays and the Train A valves. The only in situ combustibles at this location are the cables in the trays. The Train B valves CC -V176 and CC -V256 are located between Columns 12 and 13 approximately 4 ' above the grating elevation 0 '-0". Although the cables for the redundant Train A valves are not in this location, the power cables for Train A containment structure cooling unit CAH -AC-1E are routed in this area such that a fire could impact four of the six cooling units. However, the cables are routed in tray 19' above the grating elevation 0 '-0" and then in conduit to the cooling unit. There is a vertical separation of approximately 15 ' between valves CC -V176 and CC-V256 and the Train A trays. The only in situ combustibles at this location are the cables in the tray. One set of redundant valves is needed to provide component cooling water to one train of containment structure cooling units. Between Columns 17 and 18, the vertical separation is 18 ' with the lower cables 12' off the floor. The separation and height of cable from the floor provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. Between Columns 14 and 15, there is a vertical separation of 27 ', with the lower cables 19 ' off the floor. There is a minimum separation of 8 ' between the Train A valves and the Train B cables, with the Train B cables 19 ' off the floor. The separation, height of cable from the floor and lack of in situ combustibles provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-29 Between Columns 12 and 13, there is a vertical separation of 15 ' between the Train B valves and the Train A cable. The valves are 30 ' off the floor (Elevation (-) 26'-0"). The separation, height of the valves off the floor and lack of in situ combustibles provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. d. Component Cooling Head Tank Level Transmitters CC -LT-2172-1, 2, 3, CC-LT-2272-1, 2, 3, CC -LT-2192-1, 2, 3, CC -LT-2292-1, 2, 3 and Associated Flow Switches CC -FISHL-2147, CC-FISHL-2248, CC-FISHL-2247, CC-FISHL-2148 Cables associated with CC heat tank level transmitters which affect the Loop B outboard isolation valves CC -V175 and CC -V257 are routed in the same trays as the Loop A inboard isolation valves CC -V57 and CC -V121. Failures in these cables could cause total loss of PCCW to containment by initiation of a spurious

lo-lo head tank level signal. Loop B PCCW can be re -established by transferring control of valves CC -V175 and CC-V257 to local control at the RSS panel in fire area CB-F-1A-A. This removes the lo -lo head tank level isolation function and allows operators to re -open the valves. Cables associated with CC head tank level transmitters which affect the Loop A

outboard isolation valves CC -V122 and CC -V168 are routed in proximity to trays containing cables for the Loop B inboard isolation valves CC -V176 and CC-V256. Failures in these cables could cause total loss of PCCW to containment by initiation of a spurious l o-lo head tank level signal. Loop A PCCW can be re -established by transferring control of valves CC -V122 and CC-V168 to local control at the RSS panel in fire area CB -F-1B-A. This removes the lo-lo head tank level isolation function and allows operators to re-open the valves. The provision of a capability to isolate the affected portion of the circuit and

re-position the valves from another fire area satisfies the safe shutdown requirements.

e. Thermal Barrier Isolation Valves CC

-V395, CC-V428, CC-V438, CC-V439 Valves CC -V395, CC-V428, CC-V438 and CC -V439 are normally open valves which must remain open for safe shutdown. The valves are permanently disabled in the open position. The disabling of the above valves satisfies the safe shutdown requirements.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-30 f. Air Compressors and Dryers SA -C-4A, SA-C-4B, IA-D-2A, IA-D-2B and Associated Distribution Panels, Control Panels and Contactors The air compressors and their associated dryers located at elevation 0 '-0" are required only for instrument air to the primary component cooling water containment isolation valves. These valves are required to remain operable only for containment entry when manual operation of the safety injection accumulator isolation valves SI -V3, SI-V17, SI-V32, and SI -V47 and RHR inlet isolation valves RC -V22, RC-V23, RC-V87 and RC -V88 is required. The redundant air compressors and dryers are within 4 ' of one another. The Train B cables are routed in conduit from the compressors through the floor to the Train B trays. The Train B cable is routed in conduit from the air dryer to the power panel. The only in situ combustibles at this location are the cables in trays. A cross connection to the plant instrument air system is provided to back up the containment instrument air system in the event of a compressor failure. Containment isolation is provided by an air operated, fail closed valve (outboard) and a check valve (inboard). The outboard valve is operable from the Main Control Board. The cross connection is not relied upon to achieve hot/cold shutdown for containment fires and is only described here due to its potential use as a backup. The cable and control circuits are not considered Appendix R equipment and are, therefore, not listed in the respective tables. The Train A cables to valves SI -V3 and RC -V88 are routed in power and control trays a minimum of 17 ' above floor elevation 0 '-0" in the vicinity of the Train B air compressor and dryer. The trays are effectively shielded from the compressor and dryer by a 5 ' wide by 3 ' high steel ventilation duct located 8 ' above the floor between the compressor/dryer and the trays. Should the cables to valve SI-V3 fail, the accumulator can be vented by use of Train B valves SI -FV-2475 and SI-FV-2476. Further discussion of the separation between these cables is provided in Paragraph "n". Failure of the cables to RC -V88 will not prevent safe shutdown as functionally redundant valve RC -V23 will still be operable. The Train A cables to valve RC -V23 are routed in tray and conduit a minimum of 20' horizontal from the Train B air compressors and dryers and are separated by a concrete floor when they are in proximity to the equipment. The Train B cables to valves SI -V47, RC-V22 and RC -V87 are routed in trays which are separated from the Train A air compressor and dryer by a concrete floor. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-31 The cables to Train A Valve SI -V32 and Train B valve SI -V17 are routed on the opposite side of containment from the air compressors. The separation distance, radiant shielding provided by ventilation duct and lack of in situ combustibles between the air compressors/dryers and the cabling for the valves that must remain operable should the redundant compressors/dryers be damaged due to a fire provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. g. RC Pump Seal Water Isolation Valves CS -V10, CS-V28, CS-V44, CS-V59, CS-V168, and CS - Charging to RC Isolation Valves CS -V177, CS-V185 Valve CS-V168 is a normally open valve which should remain open for safe shutdown. Spurious isolation of the Train B valve CS -V168 could result in loss of RC inventory through the upstream relief valve, if CS -V10, CS-V28, CS-V44 and CS-V59 cannot be closed. This inventory is directed to the PRT and is therefore, non -recoverable. However, the postulated flow rate (12 gpm) coupled with the RCS volume shrink over the cooldown period to 350F (approximately 5 hours) is within the capabilities of the boric acid tanks. Cooldown below 350F to cold shutdown can be accomplished using the RWST. Shutdown margin is assured in all phases of this cooldown. The safe shutdown requirements are satisfied.

h. Letdown Isolation Valves CS

-V175, CS-V176, CS-V145, RC-LCV-459, RC-LCV-460 1) Excess Letdown Line Functionally redundant Train B series valves CS -V175 and CS -V176 are normally closed and remain closed for safe shutdown. The spurious opening of one valve will not prevent safe shutdown. The operators will prevent further spurious operation by tripping the power supply breakers for CS -V175 and CS -V176 at the Train B switchgear room (Fire Area: CB -F-1B-A). SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-32 2) Normal Letdown Line Functionally redundant Train A series valves CS -V145, RC-LCV-459 and RC-LCV-460 are normally open and are required to close for safe shutdown. CS -V145 can be closed from the main control room. Should this valve not close due to spurious operation, the operators can close either RC -LCV-459 or RC -LCV-460 by tripping their power supply breakers at the Train A switchgear room (Fire Area: CB -F-1A-A). This will prevent further spurious operation. The capability to isolate the letdown flow paths and mitigate spurious operations from outside the fire area satisfies the safe shutdown requirements.

i. Charging Pump Test Line Isolation Valves SI

-158, SI-159 On spurious operation of either of the normally closed, fail closed valves SI -V158 (Train B) or SI-V159 (Train A), the operators will isolate the high head injection path by closing SI -V138 and SI -V139. Charging will then be accomplished utilizing the seal injection path through valves CS -V154, CS-V158, CS-V162 and CS-V166 located in Fire Zones PP -F-1A-Z and PP-F-5B-Z. The operators can close SI-V158 and SI -V159 by tripping their power supply breakers in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The capability to provide charging to the RC System through a minimum of one flow path satisfies the safe shutdown requirements.

j. Head Vent Valves RC

-FV-2881 and RC -V323 Functionally redundant Train B series valves RC -FV-2881 and RC -V323 are normally closed and remain closed for safe shutdown. The spurious opening of one valve will not prevent safe shutdown. The operators will prevent further spurious operation by tripping the power supply breakers for RC -FV-2881 and RC-V323 at the Train B switchgear room (Fire Area: CB -F-1B-A). The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-33 k. Pressurizer Heaters RC -E-10 and Terminal Boxes EDE -TBX-X44, EDE-TBX-X47 Cables for the redundant pressurizer heaters are routed through trays from the penetration where they enter containment to the heaters at the pressurizer. The trays are separated by concrete floors and walls from the penetration to a point 20 ' from the pressurizer except between Columns 2 and 3 where there is grating. Between Columns 2 and 3, the Train B cables are routed in trays which are a minimum of 10 ' above floor elevation ( -) 26'-0". The Train A cables are routed in trays a minimum of 18 ' above the grating elevation 0 '-0". There is a minimum of 25' vertical separation between the redundant trays. The only in situ combustibles at this location are the cables in the trays. In the area near the entrance to the pressurizer cubicle, the Train B trays are 12 ' above floor Elevation ( -) 26'-0. There is a spatial separation of approximately 6 ' between the redundant trays. The only in situ combustibles at this location are the cables in the trays. The Train A trays are 8 '-4" above the floor and the Train B trays are 18 '-6" above the floor at the entrance of the pressurizer cubicle. This is a vertical separation between redundant trays of over 8 '. Inside the cubicle, the cables are routed in enclosed wireways up to the point where they are routed to the individual pressurizer heater connections. The heaters are located over 20 ' above the floor. There are no in situ combustibles in the pressurizer heater cubicle. The containment is a controlled entry area and the fire loading is very low. The use of transient combustibles is strictly controlled. Where the grating exists, the cables of interest are separated vertically by 25 ' minimum. The lower set of cables are at least 10, off the floor. This separation and the height of the cable from the floor provide acceptable fire protection and provide protection equivalent to the technical requirement of Appendix R. At the area near the entrance to the pressurizer cubicle, there is a spatial separation of 6' between the cables of interest. There are no in situ combustibles. Access to this area is extremely limited during power operation.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-34 At the entrance to the pressurizer and inside, the case is the same, with the additional factor being the routing of the cables in enclosed wireways up to the point where they are routed to the individual pressurizer heater conditions. The separation, lack of combustibles, limited access and routing of the cables in wireways provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. l. Pressurizer Relief Valves, RC-PCV-456A, RC-PCV-456B, RC-V122 and RC-V124 Cables for the pressurizer relief valves are routed in trays and conduits from the penetration where they enter containment to the valves on the top of the pressurizer.

15'. The Train A cables are routed in the area of reactor coolant pump C. Near the top of the pressurizer, the conduits enter the pressurizer cubicle and are routed on opposite sides of the cubicle over to the valves. The redundant valves are separated by 2 ' on the top of the pressurizer. There are no in situ combustibles at the top of the pressurizer. Between Columns 2 and 4 and 7 and 8, there is a minimum vertical separation of 23' between Train A and B cables. The Train B cables area minimum of 10 ' off the floor.

Between Columns 5 and 6, there is a vertical separation of 25 ' with the lower cables 14 ' off the floor. The combustibles are in two motors. The separation, height off the floor, and the enclosure of combustibles in the motors provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. At the pressurizer, the cables are routed in conduit on opposite sides of the pressurizer cubicle. At the top of the pressurizer where the valves are located, there is no access during operation and there are no in situ combustibles. Adequate fire protection is provided and provides protection equivalent to the technical requirements of Appendix R. RC-PCV-456A is a normally closed, fail closed valve whose cables are in this fire area. The spurious opening of a PORV can result in an over -cooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an

unanalyzed condition. The PORV is supplemented with a normally open, series block valve RC -V122. For all fires that have the potential to cause spurious opening of the PORV, the operators will close the block valve by procedure. This will be the first step in the procedure and can readily be accomplished from the main control room. The promptness of this action is justification for the ability to isolate the block valve prior to any spurious valve operations. Under the condition, the initial short will not cause depressurization. To prevent subsequent spurious operations, the operators will de -energize the PORV and the block valve by tripping their power supplies in the Train A switchgear room (Fire Area:

However, the same fire will not prevent the operation of the Train A equipment necessary for containment habitability. These valves are not required to reach or maintain hot standby. They are required to be closed before going to cold shutdown. These valves will be manually closed, if required, prior to decreasing reactor pressure below 600 psig. Prior to this time the accumulators are prevented from injection by reactor pressure acting against a check valve. Manual operation of the isolation valve is only necessary if both the valve circuit and the redundant vent valves are rendered inoperable by the fire. This manual operation can be delayed as much as 9 hours into the event. At Elevation 0 '-0" the cables to the redundant valves are in proximity such that a fire could affect operation of both trains of equipment. Additionally, the redundant air compressors/dryers necessary for containment habitability are in the same area. As discussed above, the valves are not required for 9 hours. To assure that one train of valves can be operated from the MCR or locally, a radiant energy shield is provided around the Train B vent valves and their related cables in the area of the air compressors. The horizontal separation distance between the redundant valves provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R.

Valves RH -V35 and RH -V36 are normally closed and their position is in consequential during all modes of plant operation with the exception of cooldown below 350F when the RH system is placed in operation. At that time it is necessary to assure that the valves remain closed. Should one of the valves open spuriously, the operators can disable its power supply in either the Train A or Train B switchgear room (Fire Areas: CB -F-1A-A or CB-F-1B-A) and manually reposition the valves located in the equipment vaults (Fire Zone: RHR -F-4B-Z or RHR-F-2A-Z).

They are separated by approximately 1 '-0" horizontally. The Train B transmitter is enclosed in a non -combustible radiant energy shield. The cable to the Train A transmitter is routed in conduit from the enclosed instrumentation tray located 14 ' above the grating Elevation 0 '-0" to the transmitter. The cable to the Train B transmitter is routed in conduit from the enclosed instrumentation tray located 15 ' above floor Elevation ( -) 26'-0" to the level transmitter.

The separation, height of the tray off of the floor, enclosure of combustibles in the motors and provision of a radiant energy shield provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. w. Pressurizer Pressure Transmitters RC -PT-455, RC-PT-456, RC-PT-457, and RC-PT-458 Redundant channels ' of pressurizer pressure instruments and cables are located in proximity. Spurious operation of two channels will initiate safety injection and containment isolation phase A signals. The operators will have the capability to terminate SI after 1 minute by use of the manual reset and block switch and terminate containment isolation by use of the manual reset switch. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B Switchgear Rooms (Fire Areas: CB-F-1A-A and CB-F-1B-A). The provision of a capability to mitigate the spurious operation of the pressure transmitters outside the fire area satisfies the safe shutdown requirements.

As only one hot leg temperature is required for safe shutdown, any of the TE 's can satisfy the safe shutdown requirements. As the TE's are at various locations around the containment, there is a minimum of 20 ' of separation except for the penetration area. At the Train A penetration area, all hot leg TE cables could fail. This function can also be performed by the Train B incore thermocouples IC -TE-1 through IC -TE-58 which are separated from the Train A penetration area by concrete walls and floors. The separation between redundant temperature monitoring capabilities and their associated cables provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. y.

As only one cold leg temperature is required for safe shutdown any one of the TE's can satisfy the safe shutdown requirements except for the penetration area. At the Train B penetration area, all cold leg TE cables could fail. This function can also be performed by the steam generator pressure instruments because cold leg temperature approximates the saturation temperature corresponding to secondary pressure. These pressure transmitters FW -PT-514, FW-PT-525, FW-PT-534 and FW -PT-545 are located in Fire Zones MS -F-3A-Z and MS-F-1B-Z.

General Systems/Equipment Analysis With the exception of the systems/equipment discussed below, a fire in this area will only affect the Train A safe shutdown equipment and cables. The redundant Train B safe shutdown equipment and cables are located in fire area CB -F-1B-A. The Appendix R separation requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-56 2. Containment Spray Pump CBS -P-9A This pump is not required for safe shutdown, however; a fire could cause a spurious start. The operators will terminate operation of the CBS pump either by tripping and locking out the motor 's circuit breaker from the MCR or by removing all power from the 4160V emergency bus E5. The safe shutdown requirements are satisfied.

3. Component Cooling Water Containment Isolation Valves CC

-V57, CC-V121, CC-V175, CC-V257 and Head Tank Level Transmitters CC -LT-2172-1, 2, 3, CC-LT-2272-1, 2, 3 A fire could cause loss of all PCCW to containment by spurious closure of the PCCW Loop B outboard isolation valves CC -V175 and CC -V257. One train of PCCW is required to maintain containment habitable for manual valve operations. PCCW is also required for cooling air compressor SA -C-4B. Should all PCCW be isolated, the operators will immediately trip the Train B air compressor SA-C-4B to preclude operating the compressor without cooling. As the containment instrument air pressure decays without SA -C-4B operating, the PCCW Loop B inboard isolation valves will close. The operators will manually reopen the PCCW Loop B outboard isolation valves CC-V175 and CC -V257 in the mechanical penetration fire area (Fire Zone: PP-F-4B-Z). The operators will then manually open IA -V530 to connect the outside containment Loop B instrument air to the inside containment instrument air system. Once containment instrument air is restored, the PCCW Loop B inboard isolation valves will reopen to reestablish PCCW cooling to the air compressor and to the Train B containment structure coolers. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-57 4. Reactor Trip Switchgear CP -CP-111 Redundant trains of cables and equipment are located in proximity. These breakers are tripped from the MCR as an initial operator action; however, a fire in the area of the reactor trip switchgear could prevent operation of both trains of tripping capability. Should this occur the operators can remove power from the reactor trip MG sets by tripping the switching station breakers that supply power to the UAT and RAT causing a loss of offsite power to the station. This trip can be initiated from the MCR as the switching station breaker control circuits are not routed through this fire area. The removal of power from the MG sets will, after a short time delay to allow for coastdown, result in de -energizing the reactor trip solenoids and; hence, insertion of the control rods. The safe shutdown requirements are satisfied.

5. Charging Pump Flow Control Valve CS

-FCV-121 and Flow Transmitter CS-FT-121 Under normal conditions, charging is accomplished by utilizing the control valve

CS-FCV-121 and its associated transmitter. Spurious closure of this valve could isolate the seal injection path. In this event the operators will utilize the high head injection path for hot standby charging flow by opening the Train B valve SI-V139. The cables, controls and equipment required for operation of SI -V139 are not contained in the fire area. For cooldown, the operators will manually align the Train B charging pump discharge and bypass valves (CS -V219 and CS -V220) to the seal injection flow path and throttle the bypass valve as required. This operator action can be delayed for up to four (4) hours. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-58 6. RC Pump Seal Water Isolation Valves CS -V10, CS-V28, CS-V44, CS-V59 and CS-V167 Valve CS-V167 is a normally open valve which should remain open for safe shutdown. Spurious isolation of the Train A valve CS -V167 could result in loss of RC inventory through the upstream relief valve. This inventory is directed to the PRT and is therefore, non -recoverable. Additionally, cables for the functionally redundant Train A valves CS -V10, CS-V28, CS-V44 and CS -V59 are routed in proximity. However, the postulated flow rate (12 GPM) coupled with the RCS volume shrink over the cooldown period to 350F (approximately 5 hours) is within the capabilities of the boric acid tanks. Cooldown below 350F to cold shutdown can be accomplished using the RWST. Shutdown margin is assured in all phases of this cooldown. The safe shutdown requirements are satisfied.

7. RC Pump Seal Injection Isolation Valves CS

-V154, CS-V158, CS-V162 and CS-V166 Under normal conditions, these valves are utilized for the seal injection flow path. Spurious closure of one valve will not prevent safe shutdown. The operators will prevent further spurious operations by removing power from the 4160V emergency bus E5. MCC E512, which powers these valves, is fed from emergency bus E5. These valves provide a redundant RC pump seal cooling capability to the safety grade thermal barrier seal cooling. Cables, controls and equipment required for the Train B thermal barrier seal cooling capability are not contained in this fire area. The Appendix R separation requirements are satisfied.

8. SI-CS Suction Cross Connection Valve CS

-V460 Valve CS-V460 is a normally closed Train A valve which is required to remain closed for cooldown. Should this valve open spuriously, the functionally redundant Train B valve CS -V475 can be closed from the MCR. Cables and controls for valve CS -V475 are not located in this fire area. The Appendix R separation requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-59 9. Tower Actuation Logic EDE -CP-248 Failures in TA logic cables or equipment could initiate a spurious tower actuation signal which would transfer Train A service water cooling capability from the pumphouse to the cooling towers. The transfer will not interrupt Train A service water nor will it have any impact on Train B service water. This failure does not prevent safe shutdown. The safe shutdown requirements are satisfied.

10. 4160V Switchgear EDE

-SWG-5 Although this equipment is not required for safe shutdown for fire in this area, there are many loads powered from it whose spurious operation could affect safe shutdown should they remain powered. For any fire in the Train A switchgear room that has a potential to impact safe shutdown, the operators will trip and lockout all ac power supplies (UAT, RAT, DG) to the bus from the MCR. To assure that breakers cannot spuriously reclose, the UAT and RAT breaker dc control power will be disabled at the disabling panel and the DG breaker control power will be disabled at the DG control panel both in the Train A diesel generator room (Fire Area DG -F-2A-A). Should the capability to trip the power supplies not be available due to prior loss of the dc control power, the operators can remove power by tripping the switching station breakers that supply power to the UAT and RAT causing a loss of offsite power to the station. This trip can be initiated from the MCR as the switching station breaker control circuits are not routed through this fire area. Subsequent to this loss of offsite power, the 4160V emergency switchgear bus E6 and Train B power will be supplied by the Train B diesel generator. The safe shutdown requirements are satisfied.

11. Emergency Feedwater Pump Control Valves FW

-FV-4214A, FW -FV-4224A, FW-FV-4234A and FW -FV-4244A These valves are normally open and at least two valves must remain open for safe shutdown. Spurious closure of one valve will not prevent safe shutdown. The operators will prevent further spurious operations by removing power from the 4160V emergency bus E5. MCC E515, which powers these valves, is fed from emergency bus E5. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-60 12. Atmospheric Relief Valves MS -PV-3001, MS-PV-3002, MS-PV-3003, MS-PV-3004 Valves MS -PV-3001, MS-PV-3002, MS-PV-3003 and MS -PV-3004 are normally closed valves. A fire would prevent operation of the Train A capabilities provided for opening and closing these valves. However, the fire would not affect the Train B capabilities and the valves will be operable for safe shutdown. Spurious opening of even one ARV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. Since the ARV 's are air operated valves, their spurious operation will be prevented by assuring that these valves are placed in a state such that the initial spurious operation in the air supply will not cause the valve to open. This will be accomplished by procedure as one of the first steps for any fire

that can affect the integral ARV air system cables. This action is justifiable since it can be accomplished from the main control room. To prevent a subsequent short that could override the initial action and cause the ARV to open, the affected air solenoids will be de -energized from the disabling panel located in Train A diesel generator room (Fire Area: DG -F-2A-A). This will isolate the faulted air supply but will not preclude operation of the ARV since the redundant air solenoids will still be operational. The safe shutdown requirements are satisfied.

13. Volume Control Tank Isolation Valve CS

-LCV-112B and CS-LCV-112D, and Charging Pump CS -P-2A & CS-P-2B Volume control tank (VCT) isolation valves CS -LCV-112B & -112C are normally open to provide a suction path from the VCT to the normally operating charging pump (CS -P-2A or -2B). These valves must stay open until RWST valve CS-LCV-112D or -112E is manually opened to provide a charging pump suction path from the RWST, or the boric acid tanks are manually aligned as a charging pump suction source. Spurious closure of a VCT isolation valve caused by a hot short would interrupt suction flow to the operating charging pump causing it to be damaged. If the standby charging pump has cables in the same area then its operation can also be degraded. The result would be no charging system flow. Since this fire area contains cables for CS -LCV-112B and CS -P-2A, this condition is potentially applicable for the system alignment with CS -P-2A the standby pump and CS -P-2B the operating pump.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-61 There is an electrical interlock that automatically opens opposite train RWST valve 1-CS-LCV-112E if VCT valve 1 -CS-LCV-112B is not full open (i.e., spuriously closes). The cables, controls and equipment required for automatically opening RWST valve 1 -CS-LCV-112E are not contained in this fire area. The open RWST valve provides a suction path so operating charging pump CS -P-2B will not be damaged. Since charging flow is available, the safe shutdown requirements are satisfied.

14. Not Used. 15. Reactor Coolant Pumps RC

-P-1A, RC-P-1B, RC-P-1C and RC -P-1D Cables required for trip of the RC pumps are routed through this fire area. These breakers are tripped from the MCR as an initial operator action; however, fire in this area could prevent this trip. Should this occur the operators will either trip the RC pump circuit breakers locally (Fire Area: NES -F-1A-Z) or by removing power from the RC pump motors by tripping the switching station breakers which supply power to the UAT and RAT, thus causing a loss of offsite power to the station. This trip can be initiated from the MCR as the switching station breaker control circuits are not routed through this fire area. The safe shutdown requirements are satisfied.

16. Pressurizer Relief Valves RC-PCV-456A, RC-V122 RC-PCV-456A is a normally closed, fail closed valve whose cables are in this fire area. The spurious opening of a PORV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. The PORV is supplemented with a normally open, series block valve RC

-V122. For all fires that have the potential to cause spurious opening of the PORV, the operators will close the block valve by procedure. This will be the first step in the procedure and can readily be accomplished from the main control room. The promptness of this action is justification for the ability to isolate the block valve prior to any spurious valve operations. Under the condition, the initial short will not cause depressurization. To prevent subsequent spurious operations, the operators will de -energize the PORV by placing the PORV main control board control switch to the closed position. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-62 17. RHR Isolation Valves RC -V23, RC-V88 RHR isolation valves are permanently disabled in the closed position. For entry into RHR shutdown cooling valve RC -V88 must be opened. This can be accomplished manually by entry into containment, if required. This manual

operation can be delayed as much as 9 hours into the event. The safe shutdown requirements are satisfied.

18. Safety Injection Pump SI

-P-6A This pump is not required for safe shutdown; however, a fire could cause a spurious start. The operators will terminate operation of the SI pump either by tripping and locking out the motor 's circuit breaker from the MCR or by removing all power from the 4160V emergency bus E5. The safe shutdown requirements are satisfied.

19. Cooling Tower Fan SW

-F-51A, Pump SW -P-110A, Valves SW -V54, SW-V56, SW-V139, Fans SWA -FN-69 and Dampers SWA -DP-66 and SWA -FN-71 During normal plant operation, the service water pumphouse is utilized for plant cooling. The cooling towers are considered a redundant capability which may be utilized for a limited period of time during the year (e.g., tunnel heat treating). Should a fire occur during this time period the operators can utilize the Train B service water pumphouse capability. The cables, controls and equipment required for the Train B service water pumphouse capability are not contained in this fire area. The Appendix R separation requirements are satisfied.

20. Pressurizer Heaters Group C, Group D, Control Group This equipment is not required for safe shutdown; however, a fire could cause spurious operations. The operators will terminate operation of the pressurizer heaters, or mitigate the condition by tripping the heaters

' circuit breaker, by tripping off -site power from the control room, or by reducing pressure by opening a PORV. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-63 21. Containment Pressure Transmitter SI -PT-937 A cable for one channel of containment pressure instrumentation is routed through this fire area. This channel inputs to 2 out of 3 and 2 out of 4 logics which initiate protective actions. A spurious signal from one channel is not sufficient to initiate the logic and perform the protective action; hence, a failure in this cable will not prevent safe shutdown. The safe shutdown requirements are satisfied.

22. Containment Enclosure Isolation Damper, PAH

-DP-35A, PAH-DP-36A Cables for dampers PAH -DP-35A and PAH -DP-36A are routed through this area. Under normal operation both dampers are open. If both dampers go closed, the Containment Enclosure Air Handling (EAH) system operates in the recirculation mode. The normal and recirculation modes for EAH system operation both satisfy the safe shutdown function. Independent operation of either damper (one open and one closed) could cause an air flow problem in EAH system. This

assumes that both redundant dampers (PAH -DP-35B and PAH -DP-36B) are in their normal open position since they would not be affected by a fire in this area. Both dampers are powered from a single Train A power supply. The circuit design is such that a spurious signal will cause both dampers to operate together either both open (normal mode) or both closed (recirculation mode). The safe shutdown requirements are satisfied.

23. Control Room Air Conditioning The non-safety related chilled water system, which is powered from a non

-safety related power supply, is normally running and aligned to either the A Train or the B Train Control Building Air Conditioning System fan unit. During normal plant operation, with the non -safety subsystem aligned for Control Room cooling on the A Train fan unit, the control switch on the MCB for the safety related train will be aligned for AUTO operation. On a loss of offsite power, the non -safety chilled water subsystem will be shut down and an automatic start sequence will be

initiated via the emergency diesel generator load sequencer to restart the AC unit and start the A Train safety chiller.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-64 In the event the A Train of the CBA fails to start, operator actions, prompted by high Control Room temperature, are assumed to secure the failed chiller and associated equipment and start the B Train. All controls for the recovery are in the Control Room. The safe shutdown requirements are satisfied.

24. Boration/Dilution Flow Control Valves, CS

-FCV-110A, -111A, -110B, -111B This area contains cables for CS -FCV-110A, -111A, -110B, -111B. Spurious opening of these valves in conjunction with spurious start of a boric acid transfer pump or reactor makeup water pump may divert boric acid from the reactor coolant system affecting cold shutdown reactivity control, or result in an unplanned dilution affecting hot standby and cold shutdown reactivity control. The operators isolate the diversion flow by closing CS -FCV-110B and -111B using the main control board control switches. The operators isolate the dilution flow by closing CS -LCV-112C using the main control board control switch. The safe shutdown requirements are satisfied.

25. Charging Pump CS

-P-2A and High Head Injection Valve SI -V-138 Either charging pump CS -P-2A or CS-P-2B is normally operating. High head injection valve SI -V-138 is normally closed. If SI-V-138 spuriously opens, CS-P-2A and CS -P-2B need to be stopped to isolate charging flow to prevent pressurizer overfill. If CS-P-2A can not be stopped from the main control room because its cables are routed through this fire area, then power will be removed from Emergency Bus E5 to stop the pump (see Item 10 analysis). A fire in this area does not affect the capability to trip CS -P-2B from the main control room. C. Evaluation The safe shutdown requirements and Appendix R separation requirements are satisfied.

The redundant Train A safe shutdown equipment and cables are located in fire area CB -F-1A-A. The Appendix R separation requirements are satisfied.

2. Containment Spray Pump CBS

-P-9B This pump is not required for safe shutdown, however, a fire could cause a spurious start. The operators will terminate operation of the CBS pump either by tripping and locking out the motor 's circuit breaker from MCR or by removing all power from the 4160V emergency Bus E6. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-75 3. Component Cooling Water Containment Isolation Valves CC -V122, CC-V168, CC-V176, CC-V256 and Head Tank Level Transmitters CC -LT-2192-1, 2, 3, CC-LT-2292-1, 2, 3 A fire could cause loss of all PCCW to containment by spurious closure of the PCCW Loop B outboard isolation valves CC -V122 and CC -V168. One train of PCCW is required to maintain containment habitable for manual valve operations. PCCW is also required for cooling the air compressor SA -C-4A. Should all PCCW be isolated, the operators will immediately trip the Train A air compressor SA-C-4A to preclude operating the compressor without cooling. As the containment instrument air pressure decays without SA -C-4A operating, the PCCW Loop B inboard isolation valves will close. The operators will manually reopen the PCCW Loop A outboard isolation valves CC-V-122 and CC -V-168 in the mechanical penetration fire area (Fire Zone: PP-F-4B-Z). The operators will then manually open IA -V50 to connect the outside containment Loop A instrument air to the outside containment Loop B instrument air. The operators will then manually open IA -V530 to connect the outside containment Loop B instrument air to the inside containment instrument air system. Once containment instrument air is restored, the PCCW Loop A inboard isolation valves will reopen to reestablish cooling to the air compressor and to the Train A containment structure coolers. The safe shutdown requirements are satisfied.

4. RC Pump Seal Water Isolation Valve CS

-V168 Valve CS-V168 is a normally open valve which should remain open for safe shutdown. Spurious isolation of the Train B valve could result in RC inventory loss through the upstream relief valves. This inventory is directed to the PRT and is therefore, non -recoverable. To preclude this loss of inventory, redundant isolation capability is provided for the RC pump seal return lines by means of Train A valves CS -V10, CS-V28, CS-V44 and CS -V59. The cables, controls and equipment required for the operation of CS -V10, CS-V28, CS-V44 and CS -V59 are not contained in this fire area. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-76 5. Excess Letdown Isolation Valves CS -V175 and CS -V176 Cables for functionally redundant fail closed valves CS -V175 and CS -V176 are routed in proximity. These valves are normally closed and remain closed for safe shutdown. Should either valve spuriously open, the operators will mitigate the spurious operation by disabling the power supply to CS -V175 at the disabling panel in the Train B diesel generator room (Fire Area: DG -F-2B-A). The safe shutdown requirements are satisfied.

6. Charging Pump Test Line Isolation Valve SI

-V158 On spurious operation of the normally closed, fail closed valves SI -V158 (Train B), the operators will maintain the normally closed high head injection path valves SI -V138 and SI -V139 closed. Charging will be accomplished utilizing the seal injection flow path through valves CS -FCV-121, CS-V154, CS-V158, CS-V162 and CS -V166. The cables controls and equipment required for operation of these valves are not contained in the fire area. The capability to provide charging to the RC System through a minimum of one flow path satisfies the safe shutdown requirements.

7. BAT to Charging Pump Isolation Valve CS

-V426 Valve CS-V426 is a normally closed valve which is opened to provide a path from the boric acid tanks to the charging pump suction. This path is required to begin cooldown. In the event that this valve is inoperable, the operators can provide a redundant path by manually positioning valves in the boric acid tank room (Fire Zone: PAB -F-2B-Z). The operators can maintain the plant in hot standby for the time required to perform this manual action. The safe shutdown requirements are satisfied.

8. SI-CS Suction Cross Connection Valves CS

-V461, CS-V475 Cables for valves CS -V461 and CS -V475 are located in proximity. Prior to beginning cooldown, the normally closed valve CS -V461 valve should remain closed or the functionally redundant valve CS -V475 should be closed. The isolation of this path will prevent the potential loss of boric acid tank inventory to the RWST during cooldown. In the event of a spurious valve operation which renders this flow path open, the plant can be maintained in hot standby for as long as 4 hours.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-77 Should this area be inaccessible due to the fire or should the operators desire to initiate the cooldown sooner than 4 hours, a gravity feed can be established from the boric acid tanks to the charging pumps. As the BAT head is lower than that required to return inventory to the RWST, there would be no loss of BAT inventory through this path and the position of these valves would be inconsequential. The safe shutdown requirements are satisfied.

9. Tower Actuation Logic EDE

-CP-249 Failures in TA logic cables or equipment could initiate a spurious tower actuation signal which would transfer Train B service water cooling capability from the pumphouse to the cooling towers. The transfer will not interrupt Train B service water nor will it have any impact on Train A service water. This failure does not prevent safe shutdown. The safe shutdown requirements are satisfied.

10. 4160V Switchgear EDE

-SWG-6 Although this equipment is not required for safe shutdown for fire in this area, there are many loads powered from it whose spurious operation could affect safe shutdown should they remain powered. For any fire in the Train B switchgear room that has a potential to impact safe shutdown, the operators will trip and lockout all ac power supplies (UAT, RAT, DG) to the bus from the MCR. To assure that breakers cannot spuriously reclose, the UAT and RAT breaker dc control power will be disabled at the disabling panel and the DG breaker control power will be disabled at the DG control panel, both in the Train B diesel generator room (Fire Area: DG -F-2B-A). Should the capability to trip the power supplies not be available due to prior loss of the dc control power, the operators can remove power by tripping the switching station breakers that supply power to the UAT and RAT causing a loss of offsite power to the station. This trip can be initiated from the MCR as the switching station breaker control circuits are not routed through this fire area. Subsequent to this loss of offsite power, the 4160V emergency switchgear bus E5 and Train A power will be supplied by the Train A diesel generator. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-78 11. Emergency Feedwater Pump Control Valves FW -FV-4214B, FW -FV-4224B, FW-FV-4234B and FW -FV-4244B These valves are normally open and at least two valves must remain open for safe shutdown. Spurious closure of one valve will not prevent safe shutdown. The operators will prevent further spurious operations by removing power from the 4160V emergency bus E6. MCC E615, which powers these valves, is fed from emergency bus E6. The safe shutdown requirements are satisfied.

12. Atmospheric Relief Valves MS

-PV-3001, MS-PV-3002, MS-PV-3003, MS-PV-3004 Valves MS -PV-3001, MS-PV-3002, MS-PV-3003 and MS -PV-3004 are normally closed valves. A fire would prevent operation of the Train B capabilities provided for opening and closing these valves. However, the fire would not affect the Train A capabilities and the valves will be operable for safe shutdown. Spurious opening of even one ARV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. Since the ARV 's are air operated valves, their spurious operation will be prevented by assuring that these valves are placed in a state such that the initial spurious operation in the air supply will not cause the valve to open. This will be accomplished by procedure as one of the first steps for any fire that can affect the integral ARV air system cables. This action is justifiable since it can be accomplished from the main control room. To prevent a subsequent short that could override the initial action and cause the ARV to open, the affecte d air solenoids will be de -energized from the disabling panel located in Train B diesel generator room (Fire Area: DG -F-2B-A). This will isolate the faulted air supply but will not preclude operation of the ARV since the redundant air solenoids will still be operational. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-79 13. Reactor Vent Valves RC -FV-2881, RC-V323 Functionally redundant series valves RC -FV-2881 (fail closed) and RC -V-323 are normally closed and remain closed for safe shutdown. The spurious opening of one valve will not prevent safe shutdown. The operators will prevent spurious opening of this path by disabling the power supply to valve RC -FV-2881 at the disabling panel in the Train B diesel generator room (Fire Area: DG -F-2B-A). The safe shutdown requirements are satisfied.

14. Pressurizer Relief Valves RC

-PCV-456B, RC-V124 RC-PCV-456B is normally closed, fail closed valve whose cables are in this fire area. The spurious opening of a PORV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. The PORV is supplemented with a normally open, series block valve RC -V124. For all fires that have the potential to cause spurious opening of the PORV, the operators will close the block valve by procedure. This will be the first step in the procedure and can readily be accomplished from the main control room. The promptness of this action is justification for the ability to isolate the block valve prior to any spurious valve operations. Under the condition, the initial short will not cause depressurization. To prevent subsequent spurious operations, the operators will de -energize the PORV by placing the PORV main control board control switch to the closed position. The safe shutdown requirements are satisfied.

15. RHR Isolation Valves RC

-V22, RC-V87 RHR isolation valves are permanently disabled in the closed position. For entry into RHR shutdown cooling valve RC -V22 must be opened. This can be accomplished by entry into containment, if required. This manual operation can be delayed as much as 9 hours into the event. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-80 16. Safety Injection Pump SI -P-6B This pump is not required for safe shutdown; however, a fire could cause a spurious start. The operators will terminate operation of SI pump either by tripping and locking out the motor 's circuit breaker from the MCR or by removing all power from the 4160V emergency bus E6. The safe shutdown requirements are satisfied. 17. Containment Enclosure Isolation Damper, PAH -DP-35B, PAH-DP-36B Cables for dampers PAH -DP-35B and PAH -DP-36B are routed through this area. Under normal operation both dampers are open. If both dampers go closed, the Containment Enclosure Air Handling (EAH) system operates in the recirculation mode. The normal and recirculation modes for EAH system operation both satisfy the safe shutdown function. Independent operation of either damper (one open and one closed) could cause an air flow problem in EAH system. This assumes that both redundant dampers (PAH -DP-35A and PAH -DP-36A) are in their normal open position since they would not be affected by a fire in this area. Both dampers are powered from a single Train B power supply. The circuit design is such that a spurious signal will cause both dampers to operate together, either both open (normal mode) or both closed (recirculation mode). The safe shutdown requirements are satisfied.

18. Control Room Air Conditioning The non-safety related chilled water system, which is powered from a non

-safety related power supply, is normally running and aligned to either the A Train or the B Train Control Building Air Conditioning System fan unit. During normal plant operation, with the non -safety subsystem aligned for Control Room cooling on the B Train fan unit, the control switch on the MCB for the safety related train will be aligned for AUTO operation. On a loss of offsite power, the non -safety chilled water subsystem will be shut down and an automatic start sequence will be initiated via the emergency diesel generator load sequencer to restart the AC unit and start the B Train safety chiller. In the event the B Train of the CBA fails to start, operator actions, prompted by high Control Room temperature, are assumed to secure the failed chiller and associated equipment and start the A Train. All controls for the recovery are in the Control Room. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-81 19. Volume Control Tank Isolation Valve CS -LCV-112C and CS-LCV-112E, and Charging Pump CS -P-2A & CS-P-2B Volume control tank (VCT) isolation valves CS -LCV-112B & -112C are normally open to provide a suction path from the VCT to the normally operating charging pump (CS -P-2A or -2B). These valves must stay open until RWST valve CS-LCV-112D or -112E is manually opened to provide a charging pump suction path from the RWST, or the boric acid tanks are manually aligned as a charging pump suction source. Spurious closure of a VCT isolation valve caused by a hot short would interrupt suction flow to the operating charging pump causing it to be damaged. If the standby charging pump has cables in the same area then its operation can also be degraded. The result would be no charging system flow. Since this fire area contains cables for CS -LCV-112C and CS -P-2B, this condition is applicable for the system alignment with CS -P-2B the standby pump and the CS -P-2A the operating pump. There is an electrical interlock that automatically opens opposite train RWST valve 1-CS-LCV-112D if VCT valve 1 -CS-LCV-112C is not full open (i.e., spuriously closes). The cables, controls and equipment required for automatically opening RWST valve 1 -CS-LCV-112D are not contained in this fire area. The open RWST valve provides a suction path so operating charging pump CS -P-2A will not be damaged. Since charging flow is available, the safe shutdown requirements are satisfied.

20. Charging Pump CS

-P-2B and High head Injection Valve SI -V-139 Either charging pump CS -P-2A or CS-P-2B is normally operating. High head injection valve SI -V-139 is normally closed. If SI -V-139 spuriously opens, CS-P-2A and CS -P-2B need to be stopped to isolate charging flow to prevent pressurizer overfill. If CS -P-2B can not be stopped from the main control room because its cables are routed through this fire area, then power will be removed from Emergency Bus E6 to stop the pump (see Item 10 analysis). A fire in this area does not affect the capability to trip CS -P-2A from the main control room. C. Evaluation The safe shutdown requirements and Appendix R separation requirements are satisfied.

2. Recirculation Damper CBA

-DP-52 Cables for damper CBA -DP-52 are routed through this area. This damper is normally closed and is required to remain closed for safe shutdown if only one main control room ventilation fan is operating. In the event of a spurious opening of the damper, the operators will isolate and bleed the air line to the dampers air operator and manually re -close the damper by means of a handwheel. The damper and its air supplies are located in the main control room HVAC equipment and duct area (Fire Area: CB -F-3B-A). The safe shutdown requirements are satisfied.

Process Control Cabinets MM -CP-153, MM-CP-297A Power cables for PCC cabinets MM -CP-153 and MM-CP-297A are routed through this fire area. The loss of power to these cabinets will result in loss of CST level transmitter CO -LT-4096 and FW -LT-4252 and emergency feedwater flow transmitters FW -FT-4214-2 and FW-FT-4234-2. The Train B CST level transmitter FW -LT-4257 is not affected by a fire in this area. Additionally, the emergency feedwater flow to two steam generators will be available along with steam generator level for all four steam generators. The Appendix R separation requirements are satisfied.

4. Normal Letdown Isolation Valve RC

-LCV-459 Cables for valve RC -LCV-459 are routed in this fire area. The cables, controls and equipment for functionally redundant valve CS -V145 are not contained in this area and; hence, will be available for safe shutdown. The Appendix R separation requirements are satisfied.

5. Control Room Air Conditioning The non-safety related chilled water system, which is powered from a non

-safety related power supply, is normally running and aligned to either the A Train or the B Train Control Building Air Conditioning System fan unit. During normal plant operation, with the non -safety subsystem aligned for Control Room cooling on the A Train fan unit, the control switch on the MCB for the safety related train will be aligned for AUTO operation. On a loss of offsite power, the non -safety chilled water subsystem will be shut down and an automatic start sequence will be initiated via the emergency diesel generator load sequencer to restart the AC unit and start the A Train safety chiller. In the event the A Train of the CBA fails to start, operator actions, prompted by high Control Room temperature, are assumed to secure the failed chiller and associated equipment and start the B Train. All controls for the recovery are in the Control Room. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-90 6. Emergency Feedwater Pump Control Valves FW -FV-4214A, FW -FV-4224A, FW-FV-4234A, FW -FV-4244A These valves are normally open and at least two valves must remain open for safe shutdown. Spurious closure of one valve will not prevent safe shutdown. The operators will prevent further spurious operations by disabling the power supplies to the unaffected valves in the Train A switchgear room (Fire Area: CB -F-1A-A). The safe shutdown requirements are satisfied.

7. Pressurizer Power Operated Relief Valve (PORV) RC

-PCV-456A A cable for RC -PCV-456A is routed in this area. Failure of this cable cannot cause the PORV to spuriously open, so the RCS pressure boundary is maintained.

-E-230A, CBA -E-230B, CBA-DP-26A, CBA-DP-26B, CBA-FN-14A, CBA-FN-14B, CBA-FN-211A, CBA-FN-211B, CBA -PDS-21206A1/A2, CBA -PDS-21206B1/B2, CBA-TCV-21200A, CBA -TCV-21200B The control building Train B mechanical room - south is a Class 1 area which for safe shutdown has a primary function of providing protection for the Train B air handling equipment for the Train B switchgear rooms and battery rooms. The area is approximately 26 ft. long by 43 ft. wide by 23 ft. high with floor area of 1120 sq. ft. and volume of 25,800 cu. ft. The in situ combustibles consist of cables in trays.

There are a total of three cable trays which run horizontally through the area. When stacked, the trays run three high with the bottom tray being an enclosed instrument tray. There is approximately 200 ft. of uncovered cable tray containing a total of approximately 50 cables. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-93 Detectors are provided throughout the area. The cable for the Train A cooling equipment is routed in a conduit and box with a one-hour, fire -rated barrier. The only exception is at an interference with two HVAC duct hangers where the one -hour wrap is butted up to the hangers and pyrocrete is installed for heat transfer protection. The conduit and box are approximately 20 ft. above the floor. There are a total of eight cables in tray within 20 ft. horizontal of the barriered conduit. The redundant Train B cables are routed in tray a minimum of 25 ft. from the barriered conduit. The spatial separation, the height above the floor, the routing of one train of cables in conduit with a one -hour, fire -rated barrier and considering the limited in situ combustibles provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III.G.2.c "in addition to 1 hour fire barrier, and automatic fire suppression system shall be installed", has been approved. 2a. Control Room Air Conditioning The non-safety related chilled water system, which is powered from a non -safety related power supply, is normally running and aligned to either the A Train or the B Train Control Building Air Conditioning System fan unit. During normal plant operation, with the non -safety subsystem aligned for Control Room cooling on the B Train fan unit, the control switch on the MCB for the safety related train will be aligned for AUTO operation. On a loss of offsite power, the non -safety chilled water subsystem will be shut down and an automatic start sequence will be initiated via the emergency diesel generator load sequencer to restart the AC unit and start the B Train safety chiller. In the event the B Train of the CBA fails to start, operator actions, prompted by high Control Room temperature, are assumed to secure the failed chiller and associated equipment and start the A Train. All controls for the recovery are in the Control Room. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-94 3. Process Protection Cabinet MM -CP-13 The power cable for the PPC cabinet MM -CP-13 is routed through this fire area. The loss of power to this cabinet will prevent opening of valves RC -V22 and RC-V87. These valves are required to be opened for cooldown below 350F when the RH System is placed in operation. Should the cable damage be such that valves cannot be operated from the MCR, the affected portion of the circuit can be isolated at the RSS panel in the Train B switchgear room (Fire Area: CB-F-1B-A) and the valves repositioned for safe shutdown. The safe shutdown requirements are satisfied.

4. Process Control Cabinet MM

-CP-297B The power cable for PCC cabinet MM -CP-297B is routed through this fire area. The loss of power to this cabinet will result in loss of CST level transmitter FW-LT-4257 and emergency feedwater flow transmitters FW -FT-4224-2 and FW-FT-4244-2. The Train A CST level transmitter FW -LT-4252 is not affected by a fire in this area. Additionally, the emergency feedwater flow to two steam generators will be available along with steam generator level for all four steam generators. The Appendix R separation requirements are satisfied.

5. Reactor Vent Valve RC

-FV-2881 A cable for the normally closed, fail closed valve RC -FV-2881 is routed through this fire area. The spurious opening of this valve will not prevent safe shutdown as functionally redundant valve RC -V323 is normally closed and has no cables, controls, or equipment in this fire area so it cannot spuriously open. The Appendix R separation requirements are satisfied.

6. Emergency Feedwater Pump Control Valves FW

-FV-4214B, FW -FV-4224B, FW-FV-4234B, FW -FV-4244B These valves are normally open and at least two valves must remain open for safe shutdown. Spurious closure of one valve will not prevent safe shutdown. The operators will prevent further spurious operations by disabling the power supplies to the unaffected valves in the Train B switchgear room (Fire Area: CB -F-1B-A). The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-95 7. Pressurizer Power Operated Relief Valve (PORV) RC -PCV-456B A cable for RC -PCV-456B is routed in this area. Failure of this cable cannot cause the PORV to spuriously open, so the RCS pressure boundary is maintained. The safe shutdown requirements are satisfied. C. Evaluation Deviations from Appendix R, Paragraph III.G.2, separation requirements exist in the Control Building El. 50 '-0" for the CBA System and have been discussed and analyzed above. A deviation from Appendix R, Paragraph III.G.2.c, "in addition to 1 hour fire barrier, an automatic fire suppression system shall be installed ", is requested. These deviations are justified based on the analysis and our assertion that additional modifications would not enhance fire protection safety. For the remainder of the systems affected in this analysis, the safe shutdown requirements and the Appendix R separation requirements are satisfied.

Analysis 1. General Area Analysis

a. Mechanical Penetration Area (PP

-F-XX-Z) The mechanical penetration area is a Class 1 concrete structure which for safe shutdown has a primary purpose of protecting the containment isolation valves for component cooling, charging pumps and RHR. The area is sectioned into compartments, separated by concrete walls, with small openings for access. This configuration would most probably limit a fire caused by transient combustibles to one zone in the area. The area contains no in situ combustibles with the exception of cable in trays. Only Train A safe shutdown cables are routed in trays. All Train B safe shutdown cables are in conduits. Personnel access to the radioactive areas will be limited to operator tours. Detectors are provided throughout the area.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-104 b. Containment Fan Enclosure Area and Containment Annulus (CE -F-l-Z) The containment fan enclosure area is a Class 1 concrete structure which for safe shutdown has a primary function of providing protection for the redundant cooling and air handling equipment for the RHR, CBS, SI equipment vaults; the charging pump rooms; and the mechanical penetration area. The area is approximately 112 feet long by 21 feet wide by 29'-6" high with a floor area of 3000 sq. ft. and volume of 90,000 cu. ft. The in situ combustibles consist of cables in trays and charcoal in filters and fiberglass ladders. There are a total of seven cable trays which are stacked four high for the Train A trays and three high for the Train B trays. The bottom tray in each stack is an enclosed instrumentation cable tray. The trays are a minimum of 13'-6" above the floor. There is approximately 275 lineal ft. of uncovered cable tray containing a total of 80 cables. With the exception of three cables, the Train B cables for the fans are routed in one -hour, fire-rated barriered conduits from the point where they enter the area to the equipment. The charcoal filters which contain 1050 lbs. of charcoal each are not required for safe shutdown nor are they within 30 ft. of the cooling units. The units have an early fire detection system internal to the units. Detectors are provided throughout the area.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-105 2. System/Equipment Analysis

a. Component Cooling Isolation Valves CC

-V175, CC-V257, CC-V122, CC-V168 The redundant component cooling containment isolation valves CC -V175, CC-V257, CC-V122 and CC -V168 are located in proximity. These valves are normally open and remain open for safe shutdown. The valves are provided with dual coil solenoids that must be energized to close the valves. The operators can prevent spurious operation by tripping the power supply breakers at the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). It should be noted, however, that these valves are required to remain operable only for containment entry when manual operation of the safety injection isolation valves SI -V3, SI-V17, SI-V32 and SI -V47 and the reactor coolant - RHR isolation valves RC-V22, RC-V23, RC-V87 and RC -V88 is required. Cables for these valves are not routed through this fire area; hence the valves would be operable from the main control room or the RSS control panels and containment entry would not be required. The safe shutdown requirements are satisfied.

b. Thermal Barrier Containment Isolation Valves CC

-V1101, CC -V1109, CC-V1092, CC -V1095 The redundant thermal barrier containment isolation valves CC -V1101, CC-V1109, CC -V1092, CC -V1095 are located in the same fire area. The redundant valves are in separate fire zones separated by a concrete wall. These valves are normally open and remain open for safe shutdown. The operators will prevent spurious operation of more than one valve by tripping the power supply breakers for these valves at the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-106 c. Charging Line Isolation Valves CS -V142, CS-V143 The redundant charging line isolation valves CS -V142 and CS -V143 are located in the same fire area. These valves are normally open and at least one valve is required to be closed for safe shutdown. The functionally redundant valve CS -HCV-182 is not located in this fire area; hence, it can be closed to isolate the normal charging line. The Appendix R separation requirements are satisfied.

d. Seal Injection Isolation Valves: CS

-V154, CS-V158, CS-V162, CS-V166 and High Head Injection Valves SI -V138, SI-V139 Under normal conditions, the seal injection isolation valves CS -V154, CS-V158, CS-V162 and CS -V166 are utilized for the seal injection flow path. Spurious closure of one of these valves will not prevent safe shutdown. The operators will prevent further spurious operations by tripping the power supply breakers in the Train A switchgear room (Fire Area: CB-F-1A-A). The high head injection valves SI -V138 and SI -V139 are normally closed valves which may be opened to provide a redundant hot standby charging path. If the seal injection path is available, the position of these valves during hot standby is inconsequential. On cooldown, the operators will either close or maintain closed the high head injection path. If the high head injection path cannot be isolated, a capability is provided to manually align and throttle the charging pumps to the seal injection flow paths. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-107 e. RC Pump Seal Water Isolation Valve CS -V167 Valve CS-V167 is a normally open valve that should remain open for safe shutdown. Spurious isolation of the Train A valve could result in loss of inventory through the upstream relief valve. This inventory is directed to the PRT and is, therefore, non -recoverable. To preclude this loss of inventory, functionally redundant isolation capability is provided by the RC pump seal return lines by means of Train A valves CS -V10, CS-V28, CS-V44 and CS -V59 and the excess letdown line by means of normally closed, fail closed valves CS -V175 or CS -V176. The cables, controls and equipment required for operation of valves CS -V10, CS-V28, CS-V44, CS-V59, CS-V175 and CS -V176 are not contained in this fire area. The Appendix R separation requirements are satisfied.

f. Containment Enclosure Cooling Units EAH

-AC-2A, EAH-AC-2B; Fans EAH-FN-5A, EAH-FN-5B; Dampers EAH -DP-3A, EAH-DP-3B and Terminal Boxes EDE -TBX-YC3, EDE-TBX-YB3 The redundant cooling units EAH -AC-2A and EAH -AC-2B are totally enclosed fiberglass insulated steel units which house the motor, fan and cooling coils. The units are separated by 8 ft. of clear space and the fan motors EAH -FN-5A and EAH -FN-5B are approximately 25 ft. apart. During normal operation only one cooling unit is required to operate. An analysis has shown that a worst case fire caused by burning five (5) gallons of heptane between the cooling units can affect potentially one cooling unit. All Train B cables required for operation of the cooling unit EAH -AC-2B are routed in one -hour, fire -rated barriered conduits from the rated fire wall where they enter the fire area to the equipment. The spatial separation, the routing of one train of cables in a conduit with a one-hour, fire -rated barrier, the limited in situ combustibles provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-108 g. Containment Enclosure Return Fans EAH -FN-31A, EAH-FN-31B and Dampers EAH -DP-25A and EAH -DP-25B. The redundant return fans EAH -FN-31A and EAH -FN-31B are located 20 ft. above the floor and are an integral part of the HVAC ducts (one in each duct). These fans are required to maintain the equipment vaults habitable for entry if manual operations are required to place RHR into operation for cold shutdown. A fire in the containment enclosure fire zone CE -F-1-Z will not prevent operation from the MCR of any equipment necessary for RHR operation; hence, habitability of the equipment vaults is not required. Analysis and field testing has confirmed that the containment enclosure supply fan EAH -FN-5A or EAH -FN-5B is sufficient to maintain the equipment vaults below the equipment 's qualified temperatures. The safe shutdown requirements are satisfied.

h. Containment Enclosure Isolation Damper, PAH

-DP-35B, PAH-DP-36B Cables for dampers PAH -DP-35B and PAH -DP-36B are routed through this area. Under normal operation both dampers are open. If both dampers go closed, the Containment Enclosure Air Handling (EAH) system operates in the recirculation mode. The normal and recirculation modes for EAH system operation both satisfy the safe shutdown function. Independent operation of either damper (one open and one closed) could cause an air flow problem in EAH system. This assumes that both redundant dampers (PAH -DP-35A and PAH -DP-36A) are in their normal open position since they would not be affected by a fire in this area. Both dampers are powered from a single Train B power supply. The circuit design is such that a spurious signal will cause both dampers to operate together, either both open (normal mode) or both closed (recirculation mode). The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-109 i. RHR Isolation Valves RC -V22, RC-V23, RC-V87, RC-V88 and Sample Valves RC -FV-2894, RC-FV-2896 Redundant cables associated with the position indicating lights for the RHR isolation valves are contained in this area. Failure of these circuits will not prevent the operators from opening the valves for entry into cold shutdown. Although this indication is desirable, other means are available to confirm RH system operability (e.g. RH Pump Flow). The safe shutdown requirements are satisfied.

j. H Pump to Cold Leg Isolation Valves RH

-V14, RH-V26 Valves RH -V14 and RH -V26 are normally open valves which are required to remain open for RH systems operation (cold shutdown). These valves and their related cables are in proximity. If either valve spuriously closes, the operators will prevent further spurious operation of the redundant valve by tripping the power supply breakers in either the Train A or Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The safe shutdown requirements are satisfied.

k. RH Pump to Hot Leg Isolation Valves RH

-V70, RH-V32 Valves RH -V70 and RH -V32 are normally closed valves which are required to remain closed for RH system operation (cold shutdown). These valves and their related cables are in proximity. If either valve spuriously opens, the operators will prevent further spurious operation of the redundant valve by tripping the power supply breakers in either the Train A or Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-110 l. RH Heat Exchanger to CS/SI Pump Isolation Valves RH-V35, RH-V36, Containment Sump Isolation Valves CBS -V8, CBS-V14 and Terminal Boxes EDE -TBX-Y32, EDE-TBX-Y35 Cables for the redundant valves RH -V35 and RH -V36 are routed in proximity to one another. Valves RH -V35 and RH -V36 are normally closed and their position is inconsequential during all modes of plant operation with the exception of cooldown below 350F when the RH system is placed in operation. At that time it is necessary to assure that the valves remain closed. Should one of the valves open spuriously the operators can disable its power supply in either the Train A or Train B switchgear rooms (Fire Areas: CB -F-1A-A or CB-F-1B-A) and manually reposition the valves located in the equipment vaults (Fire Zone RHR-F-4B-Z or RHR-F-2-A-Z). Manual operation of the valves can be delayed as much as 9 hours into the event. Therefore, no fire protection other than the existing separation is needed. The provision of a capability to mitigate the spurious operation of the valves outside the fire area satisfies the safe shutdown requirements.

m. Containment Pressure Transmitters SI

-PT-936, SI-PT-937 Redundant channels of containment pressure instruments and cables are located in proximity. Spurious operation of these channels will initiate containment spray and containment isolation Phase B. The operators will have the capability to terminate these protective actions by use of manual reset switches. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CB -1F-1A-A and CB-F-1B-A). The provision of a capability to mitigate the spurious operation of the pressure transmitters outside the fire area satisfies the safe shutdown requirements.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-111 C. Evaluation Deviations from the Appendix R, Paragraph III.G.2 separation requirements exist in the containment fan enclosure area and the mechanical penetration area, and have been discussed and analyzed above. A deviation for Appendix R, Paragraph III G.2c, "in addition to a 1 hour fire barrier, an automatic fire suppression system shall be installed ", has been approved. These deviations are justified based on the analysis and our assertion that additional modifications would not enhance fire protection safety.

Analysis Redundant equipment and cables are located in the same fire area. The plant will normally be operating on service water pumps SW -P-41A, B, C, and D. These pumps are located in the service water pump house which is a separate area (Fire Area: SW -F-1E-Z). SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-119 This area contains valves SW -V25 and SW -V54 which are normally closed. The spurious opening of SW -V25 would divert B Train service water flow to the cooling tower thus reducing cooling flow to the diesel generator and PCCW heat exchangers. Spurious opening of SW -V54 would result in the same condition for the A Train service water system. The operators will prevent further spurious operation of the redundant valve by tripping the power supply breakers for EDE -MCC-513 at the 480 Volt Unit Substation E51 (Fire Area: CB -F-1A-A) for SW -V54 and the EDE -US-64 supply breaker at 4160 Switchgear E6 (Fire Area: CB -F-1B-A) for valve SW -V25. Thus, one train of service water capability is assured. Permissive logic for redundant SW pumps could prevent the redundant SW pumps from being started (Note: one pump of each Train is normally running). The operators will prevent spurious operation of the permissive logic by tripping the power supply breakers at the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). This area contains cooling tower fan SW -F-51A, pump SW -P110A, valves SW -V54, SW-V55, SW-V56, SW-V139, fans SWA -FN-64, SWA-FN-71, damper SWA -DP-66 and switch SWA -TSH-5667. The cooling towers are considered a redundant capability which may be utilized for a limited period of time during the year (e.g., tunnel heat treating). Should a fire occur during this time period the operators can utilize the Train B service water pumphouse capability. The cables, controls and equipment required for the Train B service water pumphouse capability are not contained in this fire area. C. Evaluation The safe shutdown requirements are satisfied.

General System/Equipment Analysis With the exception of the systems/equipment discussed below, a fire in this area will only affect the Train B safe shutdown cables. The redundant Train A safe shutdown cables are located in Fire Area PAB -F-1G-A. The Appendix R separation requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-127 2. Component Cooling Water Pumps CC -P-11B, CC-P-11D and Component Cooling Water Containment Isolation Valves CC -V122, CC-V168 A fire could cause loss of all PCCW to Containment. It should be noted, however, that these valves are required to remain operable only for containment entry when manual operation of the safety injection isolation valves SI -V3, SI-V17, SI-V32 and SI -V47 and the reactor coolant - RHR isolation valves RC-V22, RC-V23, RC-V87 and RC -V88 are required. Cables for these valves are not routed through this fire area; hence, the valves would be operable from the main control room or the RSS control panels and containment entry would not be required. The safe shutdown requirements are satisfied.

3. RHR Isolation Valves RC

-V22, RC-V87 Redundant cables associated with the position indicating lights for the RH R isolation valves are contained in this area. Failure of these circuits will not prevent the operators from opening the valves for entry into cold shutdown. Although this indication is desirable, other means are available to confirm RH System operability (e.g. RH Pump Flow). The safe shutdown requirements are satisfied.

4. Volume Control Tank Isolation Valve CS

-LCV-112C and Charging Pump CS-P-2A & CS-P-2B Volume control tank (VCT) isolation valves CS -LCV-112B & -112C are normally open to provide a suction path from the VCT to the normally operating charging pump (CS -P-2A or -2B). These valves must stay open until RWST valve CS-LCV-112D or -112E is manually opened to provide a charging pump suction path from the RWST, or the boric acid tanks are manually aligned as a charging pump suction source. Spurious closure of a VCT isolation valve caused by a hot short would interrupt suction flow to the operating charging pump causing it to be damaged. If the standby charging pump has cables in the same area then its operation can also be prevented. The result would be no charging system flow. Since this fire area contains cables for CS -LCV-112C and CS -P-2B, this condition is potentially applicable for the system alignment with CS -P-2B the standby pump and CS -P-2A the operating pump.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-128 The CS-LCV-112C circuit design prevents spurious valve closure from hot shorts as follows. The field cable conductors for the motor control center (MCC) contactor close coil circuit are in different cables than the 120 V "hot" circuit conductors eliminating the hot short failure mode within the cables. Cable-to-cable hot shorts need not be postulated for thermoset cable insulation as used at Seabrook. Since CS -LCV-112C will not spuriously close, CS -P-2A as the operating charging pump will not be damaged. Also, the CS -LCV-112C and CS-P-2B cables are routed in separate concrete encased conduits within the duct bank so that one fire can not damage both the valve and the standby pump cables. Since charging flow is available, the safe shutdown requirements are satisfied. C. Evaluation The safe shutdown requirements and Appendix R separation requirements are satisfied.

Process Protection Cabinet MM -CP-12 The power cables for the PPC cabinet MM -CP-12 is routed through this fire area. The loss of power to this cabinet will prevent opening of valves RC -V23 and RC-V88. Valve RC -V88 is required to be opened for cooldown below 350F when the RH system is placed in operation. Should the cable damage be such that valves cannot be operated from the MCR, the affected portion of the circuit can be isolated at the RSS panel in the Train A switchgear room (Fire Area: CB -F-1A-A) and the valves repositioned for safe shutdown. The safe shutdown requirements are satisfied.

3. Process Control Cabinet MM

-CP-297A The power cable for PCC cabinet MM -CP-297A is routed through this fire area. The loss of power to this cabinet will result in loss of CST level transmitter FW-LT-4252 and emergency feedwater flow transmitters FW -FT-4214-2 and, FW-FT-4234-2. The Train B CST level transmitter FW -LT-4257 is not affected by a fire in this area. Additionally, the emergency feedwater flow to two steam generators will be available along with steam generator level for all four steam generators. The Appendix R separation requirements are satisfied.

4. Normal Letdown Isolation Valve RC

-LCV-459 Cables for valve RC -LC-459 are routed in this fire area. The cables, controls, and equipment for functionally redundant valve CS -V145 are not contained in this area and; hence, will be available for safe shutdown. The Appendix R separation requirements are satisfied.

Pressurizer Power Operated Relief Valve RC -PCV-456A RC-PCV-456A is a normally closed, fail closed valve whose cables are in this fire area. The spurious opening of a PORV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. The PORV is supplemented with a normally open, series block valve RC -V122. For all fires that have the potential to cause spurious opening of the PORV, the operators will close the block valve by procedure. This will be the first step in the procedure and can readily be accomplished from the main control room. The promptness of this action is justification for the ability to isolate the block valve prior to any spurious valve operations. Under the condition, the initial short will not cause depressurization. To prevent subsequent spurious operations, the operators will de -energize the PORV by tripping its power supply in the Train A switchgear room (Fire Area: CB -F-1A-A). The safe shutdown requirements are satisfied.

6. Control Room Air Conditioning The non-safety related chilled water system, which is powered from a non

-safety related power supply, is normally running and aligned to either the A Train or the B Train Control Building Air Conditioning System fan unit. During normal plant operation, with the non-safety subsystem aligned for Control Room cooling on the A Train fan unit, the control switch on the MCB for the safety related train will be aligned for AUTO operation. On a loss of offsite power, the non -safety chilled water subsystem will be shut down and an automatic start sequence will be initiated via the emergency diesel generator load sequencer to restart the AC unit and start the A Train safety chiller. In the event the A Train of the CBA fails to start, operator actions, prompted by high Control Room temperature, are assumed to secure the failed chiller and associated equipment and start the B Train. All controls for the recovery are in the Control Room. The safe shutdown requirements are satisfied.

There are a total of six cable trays which run horizontally and vertically through the area. When stacked the trays are run three high with the bottom tray being an enclosed instrumentation cable tray. There is approximately 375 ft. of uncovered cable tray containing a total of approximately 80 cables. Detectors are provided throughout the area. An analysis has shown that a worst case fire caused by burning 3.5 gallons of oil will not affect the operation of the Safe Shutdown equipment.

2. System/Equipment Analysis

a. Main Control Room Cooling CBA

-E-230A, CBA -E-230B, CBA-FN-211A, CBA -FN-211B, CBA -P-434A, CBA -P-435A, CBA-P-434B, CBA -P-435B, CBA -PDS-21202A, CBA -PDS-21202B, CBA-PDS-21206A1/A2, CBA -PDS-21206B1/B2 The redundant control room cooling equipment and cables are located in the same fire area. A fire in this area can cause total loss of this cooling capability. Should this occur, the operators will utilize the evaporator fans CBA-FN-14A, 14B to supply outside air into the control room. These fans and their cables are not in this fire area. An air inlet and exhaust path, utilizing these fans, can be established by opening certain doors in the control room complex which will allow air to enter into the fan intake plenum from the south stairwell and exhaust the control room via the double doors to the turbine building. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-148 b. Diesel Generator Room Cooling DAH-FN-25A, DAH-FN-25B, DAH-FISH-5529, DAH -FISH-5530 The Safe Shutdown cables for the fans and flow switches are routed in barriered conduit from the floor where they enter the area to the equipment (a distance of approximately 20 feet or less). The one -hour, fire -rated barrier is reduced at two locations or stops approximately two feet from the equipment because of access or potential interference. The redundant fans and dampers are separated by approximately 28 feet with the only intervening combustible being approximately 44 cables in three vertical/horizontal Train B trays and approximately 33 cables in two horizontal Train A trays. The Train A and Train B trays are separated by 8 ft. The redundant flow switches and associated conduits are separated by 45 ft. with the above trays containing the only intervening combustibles. The spatial separation, the routing of both trains of cables in separate conduits with a one -hour, fire -rated barrier and the limited in situ combustibles provide acceptable fire protection equivalent to the technical requirements of Appendix R. Note: A deviation was requested and granted for not installing suppression in this location. Since that deviation was granted the following conservative changes have been made, the electrically operated supply dampers have been changed to back draft dampers and the supply fan flow switch interlock with the exhaust fan has been removed. Cables for the flow switch are still routed in barriered conduit because their failure could effect the control circuit for the supply fan. These changes do not adversely effect the basis of the deviation.

c. Diesel Generator Control DG

-CP-76A, DG-DG-1B, EDE-SWG-6 The cables for control panels DG -CP-76A and DG -DG-1B are located in this area. Failure of these cables will render the Train B diesel inoperable from the main control room. The operators can re -establish Train B diesel operability by transferring control to the RSS panel located in the Train B diesel room (Fire Area: DG -F-2B-A). Operation of the diesel from the RSS panel will also allow re -establishing emergency power to EDE-SWG-6 by isolation of the faulted main control room cables. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-149 d. Process Protection Cabinet MM -CP-13 The power cable for the PPC cabinet MM -CP-13 is routed through this fire area. The loss of power to this cabinet will prevent opening of valves RC-V22 and RC -V87. These valves are required to be opened for cooldown below 350F when the RH system is placed in operation. Should the cable damage be such that valves cannot be operated from the MCR, the affected portion of the circuit can be isolated at the RSS panel in the Train B switchgear room (Fire Area: CB -F-1B-A) and the valves repositioned for safe shutdown. The safe shutdown requirements are satisfied.

e. Normal Letdown Isolation Valve RC

-LCV-459 Cables for valve RC -LCV-459 are routed in this fire area. The cables, controls and equipment for functionally redundant valve CS -V145 are not contained in this area and; hence, will be available for safe shutdow

n. The Appendix R separation requirements are satisfied.

f. Reactor Vent Valve RC

-FV-2881 A cable for the normally closed, fail closed valve RC -FV-2881 is routed through this fire area. The spurious opening of this valve will not prevent safe shutdown as functionally redundant valve RC -V323 is normally closed and has no cables, controls, or equipment in this fire area so it cannot spuriously open. The Appendix R separation requirements are satisfied. C. Evaluation Deviations from the Appendix R, Paragraph III.G.2 separation requirements exist in the diesel generator building El. 51 '-6" for the DAH system and have been discussed and analyzed above. A deviation from Appendix R, Paragraph III G.2c, "in addition to 1 hour fire barrier, an automatic fire suppression system shall be installed ", has been approved. These deviations are justified based on the analysis and our assertion that additional modifications would not enhance fire protection safety. For the remainder of the systems affected in this analysis, the safe shutdown requirements and the Appendix R separation requirements are satisfied.

Analysis The emergency feedwater pump building is a Class 1 concrete structure which for Safe Shutdown has a primary function of providing protection for the motor driven feedwater pump and valves. The area is approximately 79 ft. long by 28 ft. wide by 18 ft. high with a floor area of 2400 sq. ft. and a volume of 43,000 cu. ft.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-157 The in situ combustibles consist of six gallons of oil in the turbine drive of emergency feedwater pump FW -P-37A and 27 pounds of plastic in a 10 ft. step and 24 ft. extension ladder. An analysis of the Design basis Fire for this combustible is contained in the "Fire Protection Program Evaluation and Comparison to Branch Technical Position APCSB-9.5-1 Appendix A. All cables are routed in conduit. Detectors are provided throughout the area.

See Section 3.4 for a discussion of the operator response for a fire in this area.

The eight emergency feed pump control valves are separated such that valves FW-FV-4214A, B and FW-FV-4244A, B are separated by 60 feet from valves FW-FV-4224A, B and FW -FV-4234A, B. See Section 3.4 for more discussion of these valves. The redundant fans and dampers are in separate steel enclosures located 11 ft. above the floor, and separated b y 1'-6". The temperature switches are separated by over 20 '. The redundant CST Level transmitters FW -LT-4252 and FW -LT-4257 are separated by 16'. The motor driven emergency feedwater pump and recirculation valve FW -V347 are located in this fire area. For a fire in this area, the start -up feedwater pump FW -P-113 (SUFP) and start -up to EFW valves FW -V156 and FW -V163 will be utilized to satisfy the safe shutdown requirements. The SUFP low suction pressure trip must also be bypassed prior to commencing cooldown. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-158 During no -load and low load plant operations, the SUFP is aligned to non -emergency Bus 4 to provide its startup and shutdown functions. After the SUFP completes its startup function, its power supply will be transferred to emergency Bus E5 as plant power is increased. The SUFP will remain aligned to Bus E5 during 100% power operation. As power is decreased in preparation for a plant shutdown, the SUFP power supply will be transferred back to Bus

4. If the SUFP is required to perform its EFW contingency function in response to a fire that disables the Train B emergency feedwater pump, while aligned to Bus 4 coincident with a loss of offsite power, it will have to be manually transferred to Bus E5 and manually started. SUFP operation will be controlled by operating procedures including selection of the appropriate power supply and verification of adequate power supply capacity prior to starting the SUFP on the emergency diesel generator.

The main control room would not have to be evacuated for a fire in this area; hence, the operators would have the capability to control and monitor all the equipment which is powered from the electrical distribution emergency system and would be required for a safe shutdown. Additional details on the alternative safe shutdown capability are contained in Section 3.4. C. Evaluation A deviation from the requirements of Appendix R, Paragraph III.G.3 requiring the installation of fixed suppression in an area for which alternative safe shutdown capability has been developed exists in the emergency feedwater pump building. This deviation is justified based on our assertion that additional modifications would not enhance plant safety which has been insured by the alternative shutdown capability discussed in Section 3.4 and Tabulation 3.4.3.

Analysis 1. General System/Equipment Analysis With the exception of the systems/equipment discussed below, a fire in this area will only affect the Train A safe shutdown equipment and cables. The redundant Train B safe shutdown equipment and cables are located in fire area ET -F-1C-A. The Appendix R safe shutdown requirements are satisfied.

2. Component Cooling Water Isolation Valves CC

-V57, CC-V121, and Head Tank Level Transmitters CC -LT-2172-1, 2, 3, CC -LT-2272-1, 2, 3 Cables associated with head tank level transmitters which affect the Loop B outboard isolation valves CC -V175 and CC -V257 are routed in the same trays as the Loop A inboard isolation valves CC -V57 and CC -V121. Failures in these cables could cause total loss of PCCW to containment by initiation of a spurious

lo-lo head tank level signal. Loop B PCCW can be re -established by transferring control of valves CC -V175 and CC -V257 to local control at the RSS panel in fire area CB-F-1A-A. This removes the lo -lo head tank level isolation function and allows operators to re -open the valves. The safe shutdown requirements are satisfied.

3. RC Pump Seal Water Isolation Valves CS

-V10, CS-V28, CS-V44, CS-V59 The safe shutdown function of these valves is to isolate seal return in the event that valve CS -V168 spuriously closes due to a fire. As cabling for CS-V168 is not routed through this area, the position of these valves is inconsequential and will not prevent safe shutdown. The safe shutdown requirements are satisfied.

4. Letdown Isolation Valves CS

-V145, RC-LCV-459, RC-LCV-460 Functionally redundant Train A series valves CS -V145, RC-LCV-459 and RC-LCV-460 are normally open and are required to close for safe shutdown. CS-V145 can be closed from the main control room. Should this valve not close due to spurious operation, the operators can close either RC-LCV-459 or RC-LCV-460 by tripping their power supply breakers at the Train A switchgear room (Fire Area: CB -F-1A-A). This will prevent further spurious operation. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-164 5. Charging Pump Test Line Isolation Valve SI-V159 On spurious operation of the normally closed, fail closed valve SI -V159 (Train A), the operators will maintain the normally closed high head injection path valves SI -V138 and SI -V139 closed. Charging will be accomplished utilizing the seal injection flow path through valves CS -FCV-121, CS-V154, CS-V158, CS-V162 and CS -V166. The cables, controls and equipment required for operation of these valves are not contained in the fire area. The capability to provide charging to the RC System through a minimum of one flow path satisfies the safe shutdown requirements.

6. RHR Isolation Valves RC

-V23, RC-V88 RHR isolation valves are permanently disabled in the closed position. For entry into RHR shutdown cooling, valve RC -V88 must be opened. These valves are not required until 9 hours into the event. This can be accomplished manually by entry into containment, if required. The safe shutdown requirements are satisfied.

7. Emergency Feedwater Pump Control Valves FW

-FV-4214A, FW -FV-4224A, FW-FV-4234A, FW-FV-4244A These valves are normally open and at least two valves must remain open for safe shutdown. Spurious closure of one valve will not prevent safe shutdown. The operators will prevent further spurious operations by disabling the power supplies to the unaffected valves in the Train A switchgear room (Fire Area: CB -F-1A-A). The safe shutdown requirements are satisfied.

8. Main Steam Isolation Valves MS

-V86, MS-V88, MS-V90, MS-V92 Failure of the Train A cables will not prevent safe shutdown as the redundant Train B cables required for MSIV closure are routed in Fire Area ET -F-1C-A. The Appendix R separation requirements are satisfied.

9. Not used SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-165 10. Atmospheric Relief Valves MS

-PV-3002, MS-PV-3003 and Associated Solenoids Valves MS -PV-3002 and MS -PV-3003 are normally closed valves. A fire would prevent operation of the Train A capabilities provided for opening and closing these valves. However, the fire would not affect the Train B capabilities and the valves will be operable for safe shutdown. Spurious opening of even one ARV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. Since the ARV 's are air operated valves, their spurious operation will be prevented by assuring that these valves are placed in a state such that the initial spurious operation in the air supply will not cause the valve to open. This will be accomplished by procedure as one of the first steps for any fire that can affect the integral ARV air system cables. This action is justifiable since it can be accomplished from the main control room. To prevent a subsequent short that could override the initial action and cause the ARV to open, the affected air solenoids will be de -energized from the distribution panels located in Train A switchgear room (Fire Area: CB -F-1A-A). This will isolate the faulted air supply but will not preclude operation of the ARV since the redundant air solenoids will still be operational. The safe shutdown requirements are satisfied.

11. Tower Actuation Logic Pressure Transmitters SW

-PT-8272, SW-PT-8273, SW-PT-8274 Failure in this cable could initiate a spurious tower actuation signal which would transfer Train A service water cooling capability from the pumphouse to the cooling towers. This transfer will not significantly interrupt Train A service Water cooling nor will it have any impact on Train B service water. This failure does not prevent safe shutdown. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-166 12. Main Steam Pressure Transmitters FW -PT-524, FW-PT-526, FW-PT-534, FW-PT-536 Redundant channels of main steam pressure cables are located in proximity. Spurious operation of the channels will initiate safety injection and containment isolation Phase A signals. The operators will have the capability to terminate SI after 1 minute by use of the manual reset block switch and terminate the containment isolation by use of the manual reset switch. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CS -F-1A-A and CB-F-1B-A). The safe shutdown requirements are satisfied.

13. Steam Generator Level Transmitters FW

-LT-501, FW-LT-503, FW-LT-529, FW-LT-548 Cables for transmitters FW -LT-501, FW-LT-503, FW-LT-529, FW-LT-548 are located in the same fire area. A Fire could cause loss of indication for all four steam generators. However, the same fire would not affect the redundant level transmitters FW -LT-502, FW-LT-504, FW-LT-519 and FW -LT-537. The Appendix R separation requirements are satisfied.

14. Emergency Feedwater Flow Transmitters FW

-FT-4214-2, FW-FT-4224-4, FW-FT-4234-2, FW-FT-4244-4 Failure in this cable could cause spurious closure of one emergency feedwater line. The logic will prevent isolation of additional lines. This leaves three steam generators available for heat removal; hence, safe shutdown is not affected. Although, failure in this cable could also cause loss of flow indication on two emergency feedwater lines, steam generator operability can be monitored by use of SG level indication. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-167 15. Condensate Storage Tank Level FW-LT-4252 All cables are Train A. The Train B level transmitter FW -LT-4257 will be available. In addition, the cables for CST level transmitter CO -LT-4096 are not routed through this area. The safe shutdown requirements are satisfied.

16. Pressurizer Pressure Transmitters RC

-PT-455, RC-PT-457 Redundant channels of pressurizer pressure cables are located in proximity. Spurious operation of two channels will initiate safety injection and containment isolation Phase A signals. The operators will have the capability to terminate SI after 1 minute by use of the manual reset and block switch and terminate the containment isolation by use of the manual reset switch. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B Switchgear Rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The provision of a capability to mitigate the spurious operation of the pressure transmitters outside the fire area satisfies the safe shutdown requirements.

17. Reactor Coolant Temperature Elements RC

-TE-413A, RC-TE-423A, RC-TE-433A, RC-TE-443A All hot leg RC temperature element cables are routed through this area; however,

this function can also be performed by the Train B incore thermocouples IC-TE-XX. The cables for these thermocouples are routed through the Train B electrical tunnel (Fire Area: ET -F-1C-A). The Appendix R separation requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-168 18. Pressurizer Relief Valves RC -PCV-456A, RC-V122 RC-PCV-456A is a normally closed, fail closed valve whose cables are in this fire area. The spurious opening of a PORV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. The PORV is supplemented with a normally open, series block valve RC -V122. For all fires that have the potential to cause spurious opening of the PORV, the operators will close the block valve by procedure. This will be the first step in the procedure and can readily be accomplished from the main control room. The promptness of this action is justification for the ability to isolate the block valve prior to any spurious valve operations. Under the condition, the initial short will not cause depressurization. To prevent subsequent spurious operations, the operators will de -energize the PORV and the block valve by tripping their power supplies in the Train A switchgear room (Fire Area:

CB-F-1A-A). The safe shutdown requirements are required.

19. Containment Pressure Transmitter SI

-PT-935 A cable for one channel of containment pressure instrumentation is routed through this fire area. This channel inputs to 2 out of 3 and 2 out of 4 logics which initiate protective actions. A spurious signal from one channel is not sufficient to initiate the logic and perform the protective action; hence, a failure in this cable will not prevent safe shutdown. The safe shutdown requirements are satisfied. C. Evaluation The safe shutdown requirements and Appendix R separation requirements are satisfied.

Analysis 1. General System/Equipment Analysis With the exception of the systems/equipment discussed below, a fire in this area will only affect the Train A safe shutdown equipment and cables. The redundant Train B safe shutdown equipment and cables are located in fire area ET -F-1C-A. The Appendix R safe shutdown requirements are satisfied.

2. Component Cooling Water Isolation Valves CC

-V57, CC-V121 and Head Tank Level Transmitters CC -LT-2172-1, 2, 3, CC -LT-2272-1, 2, 3 Cables associated with head tank level transmitters which affect the Loop B outboard isolation valves CC -V175 and CC -V257 are routed in the same trays as the Loop A inboard isolation valves CC -V57 and CC -V121. Failures in these cables could cause total loss of PCCW to containment by initiation of a spurious lo-lo head tank level signal. Loop B PCCW can be re -established by transferring control of valves CC -V175 and CC -V257 to local control at the RSS panel in fire area CB-F-1A-A. This removes the lo -lo head tank level isolation function and allows operators to re -open the valves. The safe shutdown requirements are satisfied.

3. RC Pump Seal Water Isolation Valves CS

-V10, CS-V28, CS-V44, CS-V59 The safe shutdown function of these valves is to isolate seal return in the event that valve CS-V168 spuriously closes due to a fire. As cabling for CS -V168 is not routed through this area, the position to these valves is inconsequential. The safe shutdown requirements are satisfied.

4. Letdown Isolation Valves CS

-V145, RC-LCV-459, RC-LCV-460 Functionally redundant Train A series valves CS -V145, RC-LCV-459 and RC-LCV-460 are normally open and are required to close for safe shutdown. CS-V145 can be closed from the main control room. Should this valve not close due to spurious operation, the operators can close either RC -LCV-459 or RC-LCV-460 by tripping their power supply breakers at the Train A switchgear room (Fire Area: CB -F-1A-A). This will prevent further spurious operation. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-174 5. Charging Pump Test Line Isolation Valve SI -V159 On spurious operation of the normally closed, fail closed valve SI -V159 (Train A), the operators will maintain the normally closed high head injection path valves SI -V138 and SI -V139 closed. Charging will then be accomplished utilizing the seal injection path through valves CS -FCV-121, CS-V154, CS-V158, CS-V162 and CS -V166. The cables, controls and equipment required for operation of these valves are not contained in the fire area. The capability to provide charging to the RC system through a minimum of one flow path satisfies the safe shutdown requirements.

6. RHR Isolation Valves RC

-V23, RC-V88 RHR isolation valves are permanently disabled in the closed position. For entry into RHR shutdown cooling, valve RC -V88 must be opened. These valves are not required until 9 hours into the event. This can be accomplished manually by entry into containment, if required. The safe shutdown requirements are satisfied.

7. Emergency Feedwater Pump Control Valves FW

-FV-4214A, FW-FV-4224A, FW-FV-4234A, FW -FV-4244A These valves are normally open and at least two valves must remain open for safe shutdown. Spurious closure of one valve will not prevent safe shutdown. The operators will prevent further spurious operations by disabling the power supplies to the unaffected valves in the Train A switchgear room (Fire Area CB -F-1A-A). The safe shutdown requirements are satisfied.

8. Not used 9. Main Steam Isolation Valves MS

-V86, MS-V88, MS-V90, MS-V92 Failure of the Train A cables will not prevent safe shutdown as the redundant Train B cables required for MSIV closure are routed in Fire Area ET -F-1C-A. The Appendix R separation requirements are satisfied.

10. Not used SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-175 11. Atmospheric Relief Valves MS

-PV-3001, MS-PV-3002, MS-PV-3003, MS-PV-3004 Valves MS -PV-3001, MS-PV-3002, MS-PV-3003 and MS -PV-3004 are normally closed valves. A fire would prevent operation of the Train A capabilities provided for opening and closing these valves. However, the fire would not affect the Train B capabilities and the valves will be operable for safe shutdown. Spurious opening of even one ARV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. Since the ARV 's are air operated valves, their spurious operation will be prevented by assuring that these valves are placed in a state such that the initial spurious operation in the air supply will not cause the valve to open. This will be accomplished by procedure as one of the first steps for any fire that can affect the integral ARV air system cables. This action is justifiable since it can be accomplished from the main control room. To prevent a subsequent short that could override the initial action and cause the ARV to open, the affected air solenoids will be de -energized from the distribution panel located in Train A switchgear room (Fire Area: CB -F-1A-A). This will isolate the faulted air supply but will not preclude operation of the ARV since the redundant air solenoids will still be operational. The safe shutdown requirements are satisfied.

12. Tower Actuation Logic Pressure Transmitters SW

-PT-8272, SW-PT-8273, SW-PT-8274 Failure in this cable could initiate a spurious tower actuation signal which would transfer Train A service water cooling capability from the pumphouse to the cooling towers. This transfer will not significantly interrupt Train A service water cooling nor will it have any impact on Train B service water. This failure does not prevent safe shutdown. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-176 13. Main Steam Pressure Transmitters FW -PT-514, FW-PT-524, FW-PT-526, FW-PT-534, FW-PT-536, FW-PT-544 Redundant channels of main steam pressure cables are located in proximity. Spurious operation of the channels will initiate safety injection and containment isolation Phase A signals. The operators will have the capability to terminate SI after one (1) minute by use of the manual reset and block switch and terminate the containment isolation by use of the manual reset switch. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear room (Fire Areas: CB -F-1A-A and CB-F-1B-A). The safe shutdown requirements are satisfied.

14. Steam Generator Level Transmitters FW

-LT-501, FW-LT-503, FW-LT-529, FW-LT-548 Cables for transmitters FW -LT-501, FW-LT-503, FW-LT-529 and FW -LT-548 are located in the same fire area. A fire could cause loss of indication for all four steam generators. However, the same fire would not affect the redundant level transmitters FW -LT-502, FW-LT-504, FW-LT-519 and FW -LT-537. The Appendix R separation requirements are satisfied. 15. Emergency Feedwater Flow Transmitter FW -FT-4214-2, FW-FT-4234-2 Failure in this cable could cause spurious closure of one emergency feedwater line. The logic will prevent isolation of additional lines. This leaves three steam generators available for heat removal; hence, safe shutdown is not affected. Although failure in this cable could also cause loss of flow indication on two emergency feedwater lines, steam generator operability can be monitored by use of SG level indication. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-177 16. Condensate Storage Tank Level FW -LT-4252 All cables are Train A. The Train B level transmitter FW -LT-4257 will be available. In addition, the cables for CST level transmitter CO -LT-4096 are not routed through this area . The Appendix R separation requirements are satisfied.

17. Pressurizer Pressure Transmitters RC

-PT-455, RC-PT-457 Redundant channels of pressurizer pressure cables are located in proximity. Spurious operation of two channels will initiate safety injection and containment isolation Phase A signals. The operators will have the capability to terminate SI after 1 minute by use of the manual reset and block switch and terminate the containment isolation by use to the manual reset switch. All ESF equipment

which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The provision of a capability to mitigate the spurious operation of the pressure transmitters outside the fire area satisfies the safe shutdown requirements.

18. Reactor Coolant Temperature Elements RC

-TE-413A, RC-TE-423A, RC-TE-433A, RC-TE-443A All hot leg RC temperature element cables are routed through this area; however, this function can also be performed by the Train B incore thermocouples

IC-TE-XX. The cables for these thermocouples are routed through the Train B electrical tunnel (Fire Area: ET -F-1C-A). The Appendix R separation requirements are satisfied.

19. Containment Pressure Transmitter SI

-PT-935 A cable for one channel of containment pressure instrumentation is routed through this fire area. This channel inputs to 2 out of 3 and 2 out of 4 logics which initiate protective actions. A spurious signal from one channel is not sufficient to initiate the logic and perform the protective action; hence, a failure in this cable will not prevent safe shutdown. The safe shutdown requirements are satisfied. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-178 20. Pressurizer Relief Valves RC -PCV-456A, RC-V122 RC-PCV-456A is normally closed, fail closed valve whose cables are in this fire area. The spurious opening of a PORV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. The PORV is supplemented with a normally open, series block valve RC -V122. For all fires that have the potential to cause spurious opening of the PORV, the operators will close the block valve by procedure. This will be the first step in the procedure and can readily be accomplished from the main control room. The promptness of this action is justification for the ability to isolate the block valve prior to any spurious valve operations. Under the condition, the initial short will not cause depressurization. To prevent subsequent spurious operations, the operators will de -energize the PORV and the block valve by tripping their power supplies in the Train A switchgear room (Fire Area:

CB-F-1A-A). The safe shutdown requirements are satisfied.

21. High Head Safety Injection Valve SI

-V-138 SI-V-138 is a normally closed valve which may be opened to provide a redundant hot standby charging path. The functionally redundant Train B valve SI -V-139 is available to perform this function. Should SI -V-138 spuriously open, the charging pump may have to be stopped to prevent overfill of the pressurizer. The safe shutdown requirements are satisfied. C. EVALUATION The safe shutdown requirements and Appendix R separation requirements are satisfied.

Component Cooling Water Isolation Valves CC -V176, CC-V256 and Head Tank Level Transmitters CC -LT-2192-1, 2, 3, CC -LT-2292-1, 2, 3 Cables associated with head tank level transmitters which affect the Loop A outboard isolation valves CC -V122 and CC -V168 are routed in the same trays as the Loop B inboard isolation valves CC -V176 and CC -V256. Failures in these cables could cause total loss of PCCW to containment by initiation of a spurious lo-lo heat tank level signal. Loop A PCCW can be re -established by transferring control of valves CC -V122 and CC -V168 to local control at the RSS panel in fire area CB-F-1B-A. This removes the lo -lo head tank level isolation function and allows operators to re -open the valves. The safe shutdown requirements are satisfied.

3. RC Pump Seal Water Isolation Valve CS

-V168 Valve CS-V168 is a normally open valve which should remain open for safe shutdown. Spurious isolation of the Train B valve could result in RC inventory loss through the upstream relief valves. This inventory is directed to the PRT and is therefore, non -recoverable. To preclude this loss of inventory, redundant isolation capability is provided for the RC pump seal return lines by means of Train A valves CS -V10, CS-V28, CS-V44 and CS -V59. The cables, controls and equipment required for the operation of CS -V10, CS-V28, CS-V44 and CS -V59 are not contained in this fire area. The safe shutdown requirements are satisfied.

4. Letdown Isolation Valves CS

The safe shutdown requirements are satisfied.

7. RHR Isolation Valves RC

-V22, RC-V23, RC-V87, RC-V88 RHR isolation valves are permanently disabled in the closed position. For entry into RHR shutdown cooling, valves RC -V22 and RC -V23 must be opened.

10. Atmospheric Relief Valves MS

-PV-3002, MS-PV-3003 Valves MS -PV-3002 and MS -PV-3003 are normally closed valves. A fire would prevent operation of the Train B capabilities provided for opening and closing these valves.

For all fires that have the potential to cause spurious opening of the PORV, the operators will close the block valve by procedure. This will be the first step in the procedure and can readily be accomplished from the main control room. The promptness of this action is justification for the ability to isolate the block valve prior to any spurious valve operations. Under the condition, the initial short will not cause depressurization. To prevent subsequent spurious operations, the operators will de -energize the PORV and the block valve by tripping their power supplies in Train B switchgear room (Fire Area:

CB-F-1A-A). The safe shutdown requirements are satisfied.

20. Containment Pressure Transmitters SI

-PT-934, SI-PT-935 Redundant channels of containment pressure instruments and cables are located in proximity. Spurious operation of these channels will initiate safety injection, containment spray and containment isolation Phase A and Phase B. The operators will have the capability to terminate the SI after 1 minute by use of manual reset and block switches and terminate the containment spray and containment isolation by use of manual reset switches. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CB -1F-1A-A and CB-F-1B-A). Provision of a capability to mitigate the spurious operation of the pressure transmitters outside the fire area satisfies the safe shutdown requirements. C. Evaluation The safe shutdown requirements and Appendix R separation requirements are satisfied.

General System/Equipment Analysis With the exception of the systems/equipment discussed below, a fire in this area will only affect the Train B safe shutdown equipment and cables. The redundant Train A safe shutdown equipment and cables are located in fire area ET -F-1A-A. The Appendix R separation requirements are satisfied.

2. Component Cooling Water Isolation Valves CC

-V176, CC-V256 and Head Tank level Transmitters CC -LT-2192-1, 2, 3 and CC -LT-2292-1, 2, 3 Cables associated with head tank level transmitters which affect the Loop A outboard isolation valves CC -V122 and CC -V168 are routed in the same trays as the Loop B inboard isolation valves CC -V176 and CC -V256. Failures in these cables could cause total loss of PCCW to containment by initiation of a spurious lo-lo heat tank level signal. Loop A PCCW can be re -established by transferring control of valves CC -V122 and CC -V168 to local control at the RSS panel in fire area CB-F-1B-A. This removes the lo -lo head tank level isolation function and allows operators to re -open the valves. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-194 3. RC Pump Seal Water Isolation Valve CS -V168 Valve CS-V168 is a normally open valve which should remain open for safe shutdown. Spurious isolation of the Train B valve could result in RC inventory loss through the upstream relief valves. This inventory is directed to the PRT and is therefore, non -recoverable. To preclude this loss of inventory, redundant isolation capability is provided for the RC pump seal return lines by means of Train A valves CS -V10, CS-V28, CS-V44 and CS -V59 and the excess letdown line by means of either normally closed, fail closed valves CS -V175 or CS -V176. The cables, controls and equipment required for the operation of CS-V10, CS-V28, CS-V44 and CS -V59 are not contained in this fire area. The cables for valves CS -V175 and CS -V176 are routed in the same trays as the cables for CS-V168. To prevent the spurious closure of CS -V168 or the spurious opening of CS-V175 or CS-V176, the operators will trip their power supply breakers in the Train B switchgear room (Fire Area: CB -F-1B-A). The safe shutdown requirements are satisfied.

4. Letdown Isolation Valves CS

-V175, CS-V176 Functionally redundant Train B series valves CS -V175 and CS -V176 are normally closed and remain closed for safe shutdown. The spurious opening of one valve will not prevent safe shutdown. The operators will prevent further spurious operation by tripping the power supply breakers for CS -V175 and CS -V176 at the Train B switchgear room (Fire Area: CB -F-1B-A). The safe shutdown requirements are satisfied.

5. Charging Pump Test Line Isolation Valve SI

-V158 On spurious operation of the normally closed, fail closed valve SI -V158 (Train B), the operators will maintain the normally closed high head injection path valves SI-V138 and SI -V139 closed. Charging will be accomplished utilizing the seal injection path through valves CS -FCV-121, CS-V154, CS-V158, CS-V162 and CS-V166. The cables, controls and equipment required for operation of these valves are not contained in the fire area. The capability to provide charging to the RC System through a minimum of one flow path satisfies the safe shutdown requirements.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-195 6. Head Vent Valves RC -FV-2881 and RC -V323 Functionally redundant Train B series valves RC -FV-2881 and RC -V323 are normally closed and remain closed for safe shutdown. The spurious opening of one valve will not prevent safe shutdown. The operators will prevent further spurious operation by tripping the power supply breakers for RC -FV-2881 and RC-V323 at the Train B switchgear room (Fire Area: CB -F-1B-A). The safe shutdown requirements are satisfied.

7. RHR Isolation Valves RC

-V-22, RC-V87 RHR isolation valves are permanently disabled in the closed position. For entry into RHR shutdown cooling, valve RC -V22 must be opened. This can be accomplished manually by entry into containment, if required. This manual operation can be delayed as much as 9 hours into the event. The safe shutdown requirements are satisfied. 8. Emergency Feedwater Pump Control Valves FW -FV-4214B, FW -FV-4224B, FW-FV-4234B, FW -FV-4244B These valves are normally open and at least two valves must remain open for safe shutdown. Spurious closure of one valve will not prevent safe shutdown. The operators will prevent further spurious operations by disabling the power supplies to the unaffected valves in the Train B switchgear room (Fire Area: CB -F-1B-A). The safe shutdown requirements are satisfied.

9. Main Steam Isolation Valves MS

-V86, MS-V88, MS-V90, MS-V92 Failure of the Train B cables will not prevent safe shutdown as the redundant Train A cables required for MSIV closure are routed in Fire Area ET -F-1A-A. The Appendix R separation requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-196 10. Atmospheric Relief Valves MS -PV-3001, MS-PV-3002, MS-PV-3003, MS-PV-3004 Valves MS -PV-3001, MS-PV-3002, MS-PV-3003, and MS -PV-3004 are normally closed valves. A fire would prevent operation of the Train B capabilities provided for opening and closing these valves. However, the fire would not affect the Train A capabilities and the valves will be operable for safe shutdown. Spurious opening of even one ARV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. Since the ARV 's are air operated valves, their spurious operation will be prevented by assuring that these valves are placed in a state such that the initial spurious operation in the air supply will not cause the valve to open. This will be accomplished by procedure as one of the first steps for any fire that can affect the integral ARV air system cables. This action is justifiable since it can be accomplished from the main control room. To prevent a subsequent short that could override the initial action and cause the ARV to open, the affected air solenoids will be de -energized from the distribution panel located in Train B switchgear room (Fire Area: CB -F-1B-A). This will isolate the faulted air supply but will not preclude operation of the ARV since the redundant air solenoids will still be operational. The safe shutdown requirements are satisfied.

11. Tower Activation Logic Pressure Transmitters SW

-PT-8282, SW-PT-8283, SW-PT-8284 Failure in this cable could initiate a spurious tower actuation signal which would transfer one train of service water cooling capability form the pumphouse to the cooling towers. This transfer will not significantly interrupt Train B service water cooling nor will it have any impact on Train A service water. This failure does not prevent safe shutdown. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-197 12. Steam Generator Level Transmitters FW -LT-502, FW-LT-504, FW-LT-519, FW-LT-537 Cables for transmitters FW -LT-502, FW-LT-504, FW-LT-519, FW-LT-537 are located in the same fire area. A Fire could cause loss of indication for all four steam generators. However, the same fire would not affect the redundant level transmitters FW-LT-501, FW-LT-503, FW-LT-529 and FW -LT-548. The Appendix R separation requirements are satisfied.

13. Main Steam Pressure Transmitters FW

-PT-515, FW-PT-516, FW-PT-525, FW-PT-535, FW-PT-545, FW-PT-546 Redundant channels of main steam pressure cables are located in proximity. Spurious operation of the channels will initiate safety injection and containment isolation Phase A signals. The operators will have the capability to terminate SI after 1 minute by use of the manual reset and block switch and terminate the containment isolation by use of the manual reset switch. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The safe shutdown requirements are satisfied.

14. Emergency Feedwater Flow Transmitters FW

-FT-4214-4, FW-FT-4224-2, FW-FT-4234-4, FW-FT-4244-2 Failure in this cable could cause spurious closure of one emergency feedwater line. The logic will prevent isolation of additional lines. This leaves three steam generators available for heat removal; hence, safe shutdown is not affected. Although failure in this cable could also cause loss of flow indication on two emergency feedwater lines, steam generator perability can be monitored by use of SG level indication. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-198 15. Condensate Storage Tank Level FW -LT-4257 All cables are Train B. The Train A level transmitter FW -LT-4252 will be available. In addition, the cables for CST level transmitter CO -LT-4096 are not routed through this area. The Appendix R separation requirements are satisfied.

16. Pressurizer Pressure Transmitters RC

-PT-456, RC-PT-458 Redundant channels of pressurizer pressure cables are located in proximity. Spurious operation of two channels will initiate a safety injection signal. The operators will have the capability to terminate SI after 1 minute by use of the manual reset and block switch. All SI equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The provision of a capability to mitigate the spurious operation of the pressure transmitters outside the fire area satisfies the safe shutdown requirements.

17. Reactor Coolant Temperature RC

-TE-413B, RC-TE-423B, RC-TE-433B, RC-TE-443B All cold leg RC temperature element cables are routed through this area; however, this function can also be performed by the Train A steam generator pressure transmitters FW -PT-514, FW-PT-524, FW-PT-534, FW-PT-544 because cold leg temperature approximates the saturation temperature corresponding to secondary pressure. The cables for these PT 's are routed through fire area ET -F-1A-A. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-199 18. Containment Pressure Transmitters SI -PT-934, SI-PT-936 Redundant channels of containment pressure instruments and cables are located in proximity. Spurious operation of these channels will initiate safety injection, containment spray and containment isolation Phase A and Phase B. The operators will have the capability to terminate the SI after 1 minute by use of manual reset a nd block switches and terminate the containment spray and containment isolation by use of manual reset switches. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The provision of a capability to mitigate the spurious operation of the pressure transmitters outside the fire area satisfies the safe shutdown requirements.

19. Process Protection System Cabinet MM

-CP-2 Failure of cable will cause loss of power supply to Channel II process protection system cabinet and related instrumentation. The power supplies to redundant channel PPC are routed through other fire areas and; hence, the PPC 's will perform their safe shutdown function. The Appendix R separation requirements are satisfied.

20. Pressurizer Relief Valves RC

-PCV-456B, RC-V124 RC-PCV-456B is a normally closed, fail closed valve whose cables are in this fire area. The spurious opening of a PORV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. The PORV is supplemented with a normally open, series block valve RC-V122. For all fires that have the potential to cause spurious opening of the PORV, the operators will close the block valve by procedure. This will be the first step in the procedure and can readily be accomplished from the main control room. The promptness of this action is justification for the ability to isolate the block valve prior to any spurious valve operations. Under the condition, the initial short will not cause depressurization. To prevent subsequent spurious operations, the operators will de-energize the PORV and the block valve by tripping their power supply in the Train B switchgear room (Fire Area: CB -F-1B-A). The safe shutdown requirements are satisfied.

Containment Enclosure Isolation Damper, PAH -DP-35B, PAH-DP-36B Cables for dampers PAH -DP-35B and PAH -DP-36B are routed through this area. Under normal operation both dampers are open. If both dampers go closed, the Containment Enclosure Air Handling (EAH) system operates in the recirculation mode. The normal and recirculation modes for EAH system operation both satisfy the safe shutdown function. Independent operation of either damper (one open and one closed) could cause an air flow problem in EAH system. This assumes that redundant dampers (PAH -DP-35A and PAH -DP-36A) are in their normal open position since they would not be affected by a fire in this area. Both dampers are powered from a single Train B power supply. The circuit design is such that a spurious signal will cause both dampers to operate together, either both open (normal mode) or both closed (recirculation mode).

The safe shutdown requirements are satisfied.

22. High Head Safety Injection Valve SI

-V-139 SI-V-139 is a normally closed valve which may be opened to provide a redundant hot standby charging path. The functionally redundant Train A valve SI -V-138 is available to perform this function. Should SI -V-139 spuriously open, the charging pump may have to be stopped to prevent overfill of the pressurizer. The safe shutdown requirements are satisfied. C.

The area contains no in situ combustibles other than cables in trays and fiberglass ladders. There is one stack of three cable trays. The bottom tray is an enclosed instrument level tray located approximately 1 '-6" above the floor. The other trays are open ladder type trays which are located approximately 10 ' above the floor. The zone contains approximately 140 lineal ft. of ladder type tray. Detectors are provided throughout the area.

a. Containment Enclosure Ventilation Fans EAH

-FN-174A, EAH -FN-174B and Temperature Switches, EAH -TSH-5136, EAH -TSH-5763. Redundant ventilation fans and related cables are located in proximity. The purpose of these fans is to provide cooling for the Train A MSIV logic cabinets and the main steam pressure instrumentation. The failure of these fans will not prevent safe shutdown as the Train B logic cabinets and the main steam pressure transmitters FW -PT-514 and FW -PT-545 are not in the same fire area. The Train B logic cabinets are in the Train B switchgear room (Fire Area CB -F-1B-A) and the main steam pressure transmitters FW-PT-514 and FW -PT-545 are located in the west main steam and feedwater pipe chase (Fire Zone MS -F-1B-Z). These logic cabinets and pressure transmitters will perform their safe shutdown function. The Appendix R separation requirements are satisfied.

Spurious operation of the channels will initiate safety injection and containment isolation Phase A signals. The operators will have the capability to terminate SI after one (1) minute by use of the manual reset and block switch and terminate the containment isolation by use of the manual reset switch. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B Switchgear Rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-209 Additionally main steam line pressure transmitters FW -PT-525 and FW-PT-534 utilized for process monitoring are located in the same fire areas. A fire could cause loss of indication from both main steam line pressure transmitters. However, the same fire would not affect pressure transmitters FW -PT-514 and FW -PT-545 which are functionally redundant and are located in the west main steam and feedwater pipe chase. (Fire Area: MS-F-1B-Z). These pressure transmitters and their associated atmospheric relief valves MS -PV-3001 and MS -PV-3004 will perform their safe shutdown function. The Appendix R separation requirements are satisfied.

d. Atmospheric Relief Valves MS

-PV-3002, MS-PV-3003 and Associated Solenoids. Valves MS -PV-3002 and MS -PV-3003 are normally closed valves. A fire could prevent operation of these valves. However, the same fire would not prevent the operation of valves MS -PV-3001 and MS -PV-3004 which are in the west main steam and feedwater pipe chase (Fire Area: MS -F-1B-Z, MS-F-2B-Z). Spurious opening of even one ARV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. Since the ARV 's are air operated valves, their spurious operation will be prevented by assuring that these valves are placed in a state such that the initial spurious operation in the air supply will not cause the valve to open. This will be accomplished by procedure as one of the first steps for any fire that can affect the integral ARV air system cables. This action is justifiable since it can be accomplished from the main control room. To prevent a subsequent short that could override the initial action and cause the ARV to open, the affected air solenoids will be de -energized from the distribution panels located in Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). This will isolate the faulted air supply but will not preclude operation of the ARV since the redundant air solenoids will still be operational. The safe shutdown requirements are satisfied.

The valves MS -V88 and MS -V90 have no redundant counterpart, but they are supplied with redundant control capabilities. The Train A cables are routed in tray and conduit to the MSIV 's and their respective Train A logic cabinets. The Train B cables are routed in conduit on the opposite side of the MS & FW pipe chase. Their is a minimum horizontal separation of 10 ' up to the point that the conduits must run to the valves. The Train B conduits are routed approximately 15 ' above the floor. The MSIV 'S, connection boxes and electrical equipment are located approximately 25 ' above the floor. The Train B conduits are a minimum of 20 ' above the floor at the point they are in proximity to the Train A conduits. The Train A and Train B controls are on opposite sides of the MSIV approximately 2 ' apart. These valves are closed as an initial operator action. Should an MSIV reopen due to spurious operation (loss of power to both trains), the operators will isolate all feedwater to its respective steam generator and allow the SG to dry out. In the worst case this condition could occur to both MSIV 'S. The two steam generators and their associated MSIV 's in the west main steam and feedwater pipe chase (Fire Area: MS -F-1B-Z, MS-F-2B-Z) will be available for safe shutdown. The safe shutdown requirements are satisfied.

f. Main Steam Isolation Valves (MSIV) MS

-V86 and MS -V92 Valves MS -V86 and MS -V92 receive logic signals from both the Train A and the Train B MSIV logic cabinets. The cables and equipment in this Fire Area are associated with the Train A logic. The Train B logic cables and equipment are not routed through this fire area; hence, they will perform their safety function (MSIV trip). The Appendix R separation requirements are satisfied.

Analysis 1. General Area Analysis The west MS & FW pipe chase is a concrete structure 66 '-9" long by 14 ' wide by 57 ' high with a floor area of 935 sq. ft. and a volume of 64,700 cu. ft. The only in situ combustibles contained in the area consist of one gallon of oil in the steam recirculation pump for a fire loading of 150,000 Btu 's and fiberglass ladders for a fire loading of 1,586,000 Btu 's. There are no cables in trays. Detectors are provided throughout the area.

2. System/Equipment Analysis

a. Main Steam Pressure Transmitters FW

-PT-514, FW-PT-515, FW-PT-516, FW-PT-544, FW-PT-545, FW-PT-546 and Instrument Racks, MM-IR-52A, MM-IR-52B. Redundant channels of main steam pressure instruments and cables are located in proximity. Spurious operation of the channels will initiate safety injection and containment isolation Phase A signals. The operators will have the capability to terminate SI after 1 minute by use of the manual reset and block switch and terminate containment isolation by use of the manual reset switch. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). Additionally main steam line pressure transmitters FW -PT-514 and FW-PT-545 utilized for process monitoring are located in the same fire areas. A fire could cause loss of indication from both main steam line pressure transmitters. However, the same fire would not affect pressure transmitters FW -PT-525 and FW -PT-534 which are functionally redundant and are located in the east main steam and feedwater pipe chase. (Fire Area:

MS-F-3A-Z). These pressure transmitters and their associated atmospheric relief valves MS -PV-3002 and MS -PV-3003 will perform their safe shutdown function. The safe shutdown requirements and Appendix R separation requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-214 b. Atmospheric Relief Valves MS -PV-3001, MS-PV-3004 and Associated Solenoids. Valves MS -PV-3001 and MS -PV-3004 are normally closed valves. A fire could prevent operation of these valves. However, the same fire would not prevent the operation of valves MS -PV-3002 and MS -PV-3003 which are in the west main steam and feedwater pipe chase (Fire Areas: MS -F-1A-Z, MS-F-2A-Z). Spurious opening of even one ARV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. Since the ARV 's are air operated valves, their spurious operation will be prevented by assuring that these valves are placed in a state such that the initial spurious operation in the air supply will not cause the valve to open. This will be accomplished by procedure as one of the first steps for any fire that can affect the integral ARV air system cables. This action is justifiable since it can be accomplished from the main control room. To prevent a subsequent short that could override the initial action and cause the ARV to open, the affected air solenoids will be de -energized from the distribution panels located in Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). This will isolate the faulted air supply but will not preclude operation of the ARV since the redundant air solenoids will still be operational. The safe shutdown requirements are satisfied.

Main Steam Isolation Valves (MSIV) MS -V86 and MS -V92 The valves MS -V86 and MS -V92 have no redundant counterpart, but they are supplied with redundant control capabilities. The Train A and Train B conduits are on opposite sides of the west MS & FW pipe chase with a minimum horizontal separation of 10 ' up to the point that the conduits must run to the valves. The MSIV connection boxes and electrical equipment are located approximately 25 ' above the floor. The Train B conduits are a minimum of 20 ' above the floor at the point they are in proximity to the Train A conduits. The Train A and Train B controls are on opposite sides of the MSIV approximately 2 ' apart. These valves are closed as an initial operator action. Should an MSIV reopen due to spurious operation (loss of power to both trains), the operators will isolate all feedwater to its respective steam generator and allow the SG to dry out. In the worst case this condition could occur to both MSIV 'S. The two steam generators and their associated MSIV 's in the east main steam and feedwater pipe chase (Fire Areas: MS -F-1A-Z and MS-F-2A-Z) will be available for safe shutdown.

Analysis Loss of ED -I-4, ED-PP-5, ED-CP-532, MM-CP-153 will cause loss of CST level instrumentation CO -LT-4096. Redundant equipment is located in fire area EFP -F-1-A. RC pump switchgear control power (ED -SWG-l and ED-SWG-2) is lost. The RC pump switchgear is located in the fire area. The operator will trip the pumps by tripping offsite power from the control room. Pressurizer heaters C, D and control group control power (ED -US-11 and ED -US-23) will be lost due to this fire. If the heaters require tripping, an operator will do so manually in the Train A switchgear room (Fire Area: CB -F-1A-A). Alternatively, the operator can reduce pressure by opening a PORV. Redundant heaters are available with control power from the emergency DC bus. Cables from EDE -SWG-5 are located in this fire area. Loss of one cable could cause loss of offsite power which is acceptable since both diesel generators are available. C. Evaluation The safe shutdown requirements are satisfied.

See "Fire Protection Program Evaluation and Comparison to Branch Technical Position APCSB 9.5 -1 Appendix A" for analysis of 6600 lbs. of charcoal in CAP -F-40. c. The Train A safe shutdown cables are routed in trays. The Train B safe shutdown cables are routed in conduits with a one -hour, fire -rated barrier from the fire area boundary where they enter the PAB to the fire area boundary where they exit or the equipment at which they terminate, except as discussed in the zone analyses.

d. Detectors are provided in all zones of the PAB with the exception of Fire Zones PAB

-F-1B-Z, PAB-F-1F-Z and PAB -F-1K-Z. e. Suppression is provided in Fire Zone PAB -F-2C-Z. Details are provided in the zone analysis.

f. Early fire detection by use of carbon monoxide detectors within the

charcoal filter CAP -F-40 is provided.

g. Volume control tank (VCT) isolation valves CS

-LCV-112B & -112C are normally open to provide a suction path from the VCT to the normally operating charging pump (CS -P-2A or -2B). These valves must stay open until RWST valve CS -LCV-112D or -112E is manually opened to provide a charging pump suction path from the RWST, or the boric acid tanks are manually aligned as a charging pump suction source. Spurious closure of a VCT isolation valve caused by a hot short would interrupt suction flow to the operating charging pump causing it to be damaged. If the standby charging pump has cables in the same area then its operation can also be degraded. The result would be no charging system flow. The following PAB fire zones have been combined into one fire area for analysis purposes: PAB-F-1A-Z, PAS-F-1J-Z, PAB-F-1K-Z, PAB-F-2A-Z, PAB-F-2B-Z, PAB-F-2C-Z, PAB-F-3A-Z, and PAB -F-3B-Z. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-239 Since this combined fire area contains cables for CS -LCV-112B, CS-LCV-112C, CS-P-2A and CS -P-2B, this condition is potentially applicable for the system alignment with either combination of CS -P-2A and CS-P-2B as the standby pump and operating pump. The CS-LCV-112B and CS -LCV-112C circuit design prevents spurious valve closure from hot shorts as follows. The field cable conductors for the motor control center (MCC) contactor close coil circuit are in different cables than the 120 V "hot" circuit conductors eliminating the hot short failure mode within the cables. Cable -to-cable hot shorts need not be postulated for thermoset cable insulation as used at Seabrook. Also, the barriered conduit for CS -LCV-112C prevents Train B cable damage. Since CS-LCV-112B and CS -LCV-112C will not spuriously close, CS-P-2A or -2B as the operating charging pump will not be damaged.

1) Specific Zone Analysis This zone at Elevation (

-) 6'-0" and (-) 26'-0" of the PAB is bounded by concrete floors, ceiling and walls with penetrations to other zones. The zone is approximately 96 ' long by 75 ' wide by 11 ' to 18' high with floor area of 1980 sq. ft. and a volume of 23,782 cu. ft. All Train B safe shutdown cables are routed in conduit with a one-hour, fire -rated barrier.

Redundant valves CS -V196 and CS -V197 are located in the same fire zone and are separated by approximately 3 ' horizontal separation. These valves are normally open

valves that remain open for Safe Shutdown. The spurious closure for one valve will not prevent shutdown. The operators will prevent further spurious operation by tripping the power supply breakers at the Train A or Train B switchgear rooms (Fire Areas: CB -F-1A-A or CB-F-1B-A). See additional CS system discussion on CS -LCV-112B, CS-LCV-112C, CS-P-2A and CS -P-2B in the General Area Analysis, Section B.1.g.

Redundant channels of containment pressure (SI -PT-936 and SI-PT-937) cables are located in proximity. Spurious operation of these channels will initiate containment spray and containment isolation Phase B. The operators will have the capability to terminate these protective actions by use of manual reset switches. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CB-F-1A-A and CB-F-1B-A).

c. Fire Zone PAB

-F-1K-Z (Tabulation 3.2.7.67)

1) Specific Zone Analysis This zone between Elevation (

-) 6'-0" and roof Elevation 81 '-0" of the PAB is bounded by concrete floors, ceilings and walls with penetrations to other zones. The zone is approximately 68 ' long by 9' wide by 75 ' high with a floor area of 4,620 sq. ft. and a volume of 75,370 cu. ft. There is no tray in the zone and all cables are routed in conduit. All Train B safe shutdown cables are routed in conduit with a one-hour, fire -rated barrier. There are no in situ combustibles in the zone.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-247 2) System Analyses a) Chemical and Volume Control (CS) System This zone contains cables routed in conduit for Train A valves CS -LCV-112B and CS -LCV-112D. The Train B cables for their redundant counterpart valves CS-LCV-112C and CS -LCV-112E are routed in barriered conduit in the zone. There is 13 ' horizontal separation between the conduits containing the redundant cables. See additional CS system discussion on CS -LCV-112B, CS-LCV-112C, CS-P-2A and CS -P-2B in the General Area Analysis, Section B.1.g. b) PAB Air Handling (PAH System) This zone contains cables routed in conduit to Train A damper PAH -DP-43A. The Train B cables to redundant damper PAH -DP-43B are routed in barriered conduit in the zone. The only exception to the barrier is a short length of flexible conduit whose wrapping would interfere with the damper operator. The dampers are located approximately 15' above the floor. The area containing the dampers is a concrete and steel enclosed air plenum with limited access and no combustibles. These dampers and the fans which they control are not needed unless the main ventilation system is lost due to loss of off-site power or unless the temperature in the PCCW area exceeds 40C (104F). SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-248 c) Service Water (SW) System This zone contains cables routed in conduit for Train A valve SW-V4. The Train B cables for its redundant counterpart valve SW-V5 are routed in barriered conduit in the zone. The only exception to the barrier is one cable which runs in flexible conduit between a limit switch on valve SW-V5 to its motor operator. There is 8 ' horizontal separation between the barriered conduit for valve SW -V5 and valve SW -V4. There is 16 ' horizontal separation between the redundant valves. The valves are located approximately 15 ' above floor Elevation 53 '-0" and 3' above platform Elevation 65 '-0. This zone also contains cables routed in conduit for Train A valve SW-V74. The position of this valve is only important when the Train A cooling tower capabilities are in use at which time the valve should be closed and should remain closed. In the event this valve opens spuriously, the operators can either transfer the Train A service water to the pumphouse or utilize the Train B service water system. This satisfies the safe shutdown requirements.

3) Summary For the CS system above, the routing of the Train B cables in conduit with a one

-hour, fire-rated barrier; the spatial separation between the Train A and Train B conduits; and considering the absence of in situ combustibles in the zone provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III G.2.c "in addition to 1 hour fire barrier, an automatic fire suppression system shall be installed ", has been approved.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-249 For the PAH system above, the routing of the Train B cables in conduit with a one -hour, fire-rated barrier; the height of the dampers above the floor; the absence of in situ combustibles in the zone and the fact that a fire in the area could not cause loss of off-site power, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III.G.2 has been approved. For the SW system above, the routing of the Train B cables in conduit with a one -hour, fire -rated barrier; the horizontal separation of 8 ' between conduit and valve and 16 ' between the valves themselves; the height of the valves from the floor; and considering the absence of in situ combustibles in the zone provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III G.2.c "in addition to 1 hour fire barrier, an automatic fire suppression system shall be installed ", has been approved.

d. Fire Zone PAB

-F-2A-Z (Tabulation 3.2.7.68)

1) Specific Zone Analysis This zone at Elevation 25

'-0" of the PAB is bounded by concrete floor, ceiling and walls (South and East) and is contiguous to fire zones PAB -F-2B-Z and PAB -F-2C-Z. The northern boundary consists of partial height concrete walls and an 11 ' wide access passage. The western boundary consists of full height concrete walls and metal partitions. There are penetrations for tray, ducts, and pipes to other fire zones. The zone is approximately 44 ' long by 39' wide by 26 ' high with a floor area of 1550 sq. ft and a volume of 40,000 cu ft. No safe shutdown equipment is contained in the zone, only safe shutdown cables. Combustibles are 71 pounds of plastic (fiberglass ladders) for a total fire loading of 596 Btu per sq. ft. of floor area and limited in situ combustibles. This is classed as a low fire load. Detectors are provided throughout the zone.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-250 2) System Analyses a) Chemical and Volume Control (CS) System This zone contains cables routed in tray for the redundant boric acid tank level transmitters CS -LT-102 and CS-LT-106. These tank levels are only required once cooldown has been initiated. Should both transmitter cables be damaged by a fire, the operators can utilize the Train B level transmitter CS -LT-7464. This transmitter and its associated cable are not contained in this fire zone. The indicator for this transmitter is located at the RSS panel in the Train B switchgear room (Fire Area: CB -F-1B-A). This zone contains cables routed in tray and conduit for the boric acid pump CS -P-3A and for the boric acid to charging pumps isolation valve CS -V426. Cables for the redundant Train B boric acid pump CS -P-3B are routed in barriered conduits in Fire Zones PAB -F-2B-Z and PAB -F-2C-Z. Valve CS-V426 has no electrically operated redundant counterpart. Should the valve be damaged by a fire, the operator will establish a gravity path from the BAT 's to the charging pump suction by the repositioning to manual valves in the boric acid pump room (Fire Zone PAB-F-2B-Z). These valves are not required to be operated until boric acid is required for shutdown reactivity. This would be up to four hours into the event. See additional CS system discussion on CS -LCV-112B, CS-LCV-112C, CS-P-2A and CS -P-2B in the General Area Analysis, Section B.1.g.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-251 This zone contains cables for CS-FCV-110A, -111A, -110B, -111B. Spurious opening of these valves in conjunction with spurious start of a boric acid transfer pump or reactor makeup water pump may divert boric acid from the reactor coolant system affecting cold shutdown reactivity control, or result in an unplanned dilution affecting hot standby and cold shutdown reactivity control. The operators isolate the diversion flow by closing

CS-FCV-110B & -111B using the main control board control switches. The operators isolate the dilution flow by closing CS -LCV-112B or CS -LCV-112C using the main control board control switch. b) Containment Enclosure Air Handling (EAH) System This zone contains cable routed in barriered conduit for the Train B fan EAH -FN-5B. The cables for the redundant Train A fan EAH -FN-5A are routed in trays in fire zone PAB-F-2C-Z. There is approximately 16 ' horizontal separation between the barriered conduit and the redundant tray. c) Electrical Distribution Emergency (EDE) System All cables are Train A. The functionally redundant cables are located in other fire areas.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-252 d) PAB Air Handling (PAH) System Cables and equipment for outboard isolation dampers PAH-DP-35A and PAH -DP-36A and inboard isolation dampers PAH -DP-35B and PAH -DP-36B are routed in trays and conduits in proximity to one another. Under normal operation both outboard and both inboard dampers are open. If both outboard or both inboard dampers go closed, the Containment Enclosure Air Handling (EAH) system operates in recirculation mode. The normal and recirculation modes for EAH system operation both satisfy the safe shutdown function. If the outboard dampers and the inboard dampers operate independently such that either the supply or the exhaust path but not both are isolated, there could be an air flow problem in EAH system. Outboard dampers are powered from a single Train A power supply. Inboard dampers are powered from a single Train B power supply. The circuit design for the outboard and inboard dampers is such that a spurious signal in either or both circuits will cause both outboard and inboard dampers to operate together, either both open (normal mode) or both closed (recirculation mode). This zone contains cables routed in tray for the Train A fan PAH-FN-42A and damper PAH -DP-357. The cables for the redundant Train B fan PAH -FN-42B and damper PAH-DP-358 are routed in barriered conduit in fire zone PAB-F-2C-Z. There is greater than 50 ' of horizontal separation between the tray and the redundant barriered conduit. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-253 e) Service Water (SW) System This zone contains cable routed in tray for the Train A pumps SW-P-41A and SW -P-41C and valve SW -V54. The cables for the redundant Train B pumps SW -P-41B and SW-P-41D and valve SW -V25 are routed in barriered conduits in fire zone PAB -F-1A-Z. There is approximately 25' of horizontal separation between the tray and the redundant barriered conduits. For the other Train A cables routed in this zone, the redundant cables and equipment are contained in other fire areas. f) Service Water Air Handling (SWA) System All cable are Train A, the redundant cables are located in other fire areas.

3) Summary For the CS system above, the provision of a manual valve alignment capability that is not required for up to four hours into the event satisfies the safe shutdown requirements. Also, the capability to isolate the boric acid diversion flow and the dilution flow using the main control board control switches satisfies the safe shutdown requirements.

For the EAH, PAH and SW systems above, the routing of the Train B cables in a one -hour, fire -rated barrier; the horizontal separation of 16 ', 25' and 50' respectively; and the low combustibles loading in the zone, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III.G.2.c, "in addition to 1 hour fire barrier, an automatic fire suppression system shall be installed ", has been approved. For the EDE and SWA systems above, the Appendix R separation requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-254 e. Fire Zone PAB -F-2B-Z (Tabulation 3.2.7.69)

1) Specific Zone Analysis This zone at Elevation 25

'-0" of the PAB is bounded by concrete floor, ceiling and walls (South and West) and is contiguous to fire zones PAB -F-2A-Z and PAB -F-2C-Z. The northern and eastern boundaries consists of full height concrete walls and metal partitions. There are penetrations for tray, ducts and pipes to other fire zones. The zone is approximately 28 ' long by 37 ' wide by 16 ' high with a floor area of 1300 sq. ft. and a volume of 33,800 sq. ft. Combustibles are limited to 2.0 pounds of grease for a fire loading of 36,000 Btu and cables in open trays for a total fire loading of 6000 Btu per sq. ft. of floor area. Detectors are provided throughout the zone.

2) System Analyses a) Chemical and Volume Control (CS) System The redundant boric acid tank level transmitters CS

-LT-102 and CS-LT-106 are located in the same fire zone. Should both transmitters be unavailable due to fire damage, the operators can utilize the Train B level transmitter CS-LT-7464. This transmitter and its associated cable are contained in this fire zone. The indicator for this transmitter is located on the RSS panel in the Train B switchgear room (Fire Area: CB -F-1B-A). Should all level transmitters be unavailable, the operators will open the cross-connect valve s CS-V437 and CS -V1207 and boric acid tank isolation valves CS -V410 and CS -V416 allowing charging pump suction from both boric acid tanks. The combined inventory of the two tanks is sufficient to complete the cooldown thus eliminating the need for tank level monitoring.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-255 Redundant boric acid pumps CS -P-3A and CS -P-3B and the valve CS -V426 are located in the same fire zone. Should both pumps or the valve be damaged by the fire, th e operators will establish a gravity flow path from the BAT 's to the charging pump suction by repositioning of manual valves in the fire zone. Valves CS -V410, CS-V416, CS-V437, CS-V1207, CS-V439 and CS -V442 are manual valves required for gravity feed from the boric acid tanks to the charging pumps or cross-connecting the boric acid tanks in response to a loss of level indication. These valves are not required to be operated until boric acid is required for shutdown reactivity. This would be upon commencement of cooldown, up to four hours into the event, and the valves would then be accessible for manual operation. During this time the plant would be maintained in hot standby with RC inventory makeup provided by the RWST. See additional CS system discussion on CS -LCV-112B, CS-LCV-112C, CS-P-2A and CS -P-2B in the General Area Analysis, Section B.1.g.

This zone contains cables for CS-FCV-110A, -111A, -110B, -111B and the valves. Spurious opening of these valves in conjunction with spurious start of a boric acid transfer pump or reactor makeup water pump may divert boric acid from the reactor coolant system affecting cold shutdown reactivity control, or result in an unplanned dilution affecting hot standby and cold shutdown reactivity control. The operators isolate the diversion flow by closing CS -FCV-110B & -111B using the main control board control switches. The operators isolate the dilution flow by closing CS -LCV-112B or CS-LCV-112C using the main control board control switch.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-256 b) PAB Air Handling (PAH) System This zone contains cables routed in tray and conduit for the Train A fan PAH -FN-42A and dampers PAH -DP-43A and PAH-DP-357. The cables for the redundant Train B fan PAH-FN-42B and dampers PAH -DP-43B and PAH-DP-358 are routed in barriered conduit in fire zone PAB-F-2C-Z. There is 4 ' horizontal separation between the Train A raceways and the Train B equipment and barriered conduit. The Train A trays are a minimum of 8 ' above floor Elevation 25 '-0". A total of 3 trays exist in the stack with the bottom tray an enclosed instrument level tray containing no Safe Shutdown cables. The Train B damper PAH-DP-358 is located approximately 18 ' above floor Elevation 25 '-0". 3) Summary For the CS system above, the provision of a manual valve alignment capability that is not required for up to four hours into the event satisfies the safe shutdown requirements. Also, the capability to isolate the boric acid diversion flow and the dilution flow using the main control board control switches satisfies the safe shutdown requirements. For the PAH system above, the routing of the Train B cables in conduit with a one -hour, fire -rated barrier in another zone of the PAB; the 4 ' horizontal between the Train A and Train B equipment; the 8 ' height of the tray above the floor; and considering the low combustibles loading in the zone, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III G.2.c. "in addition to 1 hour fire barrier, automatic fire suppression system shall be installed ", has been approved.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-257 f. Fire Zone PAB -F-2C-Z (Tabulation 3.2.7.70)

1) Specific Zone Analysis This zone at Elevation 25

'-0" of the PAB is bounded by concrete floors, ceilings and walls (North, East and West) and is contiguous to fire zones PAB -F-2A-Z and PAB -F-2B-Z to the South. The southern boundary consists of full height partitions, full and partial height concrete walls and an 11' wide access passage. There are penetrations for tray, ducts and pipes to other fire zones. The zone is approximately 100 ' long by 75 ' wide by 26 ' high with a floor area of 7,200 sq. ft. and a volume of 187,000 cu. ft. The trays installed at Elevation 25 '-0" are in stacks five and six high by four wide, as a worst case, with a minimum of 4 ' between the Train A and Train B stacks. There are several areas where the trays have vertical drops through the floor. With a limited number of exceptions, the trays are a minimum of 10 ' above the floor. Metal covers are provided around the vertical trays near column lines 2 and C. The in situ combustibles are limited to cables in open trays which provide a fire load of 16,000 Btu per square foot of floor area; the boron injection pumps which contain 0.25 gallons of oil are a fire loading of 37,500 Btu; the primary component cooling water pumps CC-P-11A, 11B, 11C and 11D containing a total of four gallons of oil for a fire loading of 600,000 Btu; 41/2 ton monorail crane hoist CS -CR-5 containing 0.5 gallons of oil for a fire loading of 75,000 Btu; and 31/2 ton monorail crane hoist CS -CR-13 containing 0.5 gallons of oil for a fire loading of 75,000 Btu. The concentrated fire load in this zone is 30,000 Btu per squar e foot of tray. Because of the concentrated fire load, we have installed sprinklers to control transient fires in the area of the trays. To protect the PCCW pumps against a fire from a transient combustible, we have installed a pre -action system, using high temperature heads over the pumps and the surrounding area. Spray shields will be installed over the PCCW pump motors. Detectors are provided throughout the zone.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-258 2) System Analyses a) Primary Component Cooling Water (CC) System The redundant Primary Component Cooling Water (PCCW) pumps are located in the same fire area. The CC System is configured such that there are two 100% capacity PCCW pumps in each train either of which can be utilized for safe shutdown. The spatial separation between Train A pump CC-P-11A and Train B pump CC -P-11D is in excess of 20' with a metal partition between them. The spatial separation between Train A pump CC -P-11C and Train B pump CC-P-11B is in excess of 20 ' with a metal partition between them. The cables to the Train B pumps are routed in barriered conduit from the point they enter the PAB to the pump motors. The conduits are barriered in the vicinity of the Train B pumps. The Train B pumps have a spatial separation of 25 ' from the Train A trays and 15 ' from the Train B trays. The redundant PCCW heat exchanger valves CC-TV-2171-1, 2 and CC -TV-2271-1, 2 and their associated controls and instrument rack MM -IR-93 are located in the same fire area. The cables for the Train B valves CC -TV-2271-1 and CC-TV-2271-2 and the Train B controllers are routed in barriered conduits. The only exception is a reduction in the barriers at the controllers and valves due to interference with instrument lines. The redundant valves are mounted approximately 20 ' above the floor with a minimum separation of 2 '. The controllers are wall and instrument rack mounted and are separated by approximately 20 '. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-259 The redundant temperature elements CC -TE-2171, CC-TE-2197 and CC -TE-2271, CC-TE-2297 are located in the same fire area. The cable for one of the redundant Train B temperature elements is routed in a barriered conduit. The trip logic is a 2 out of 2 logic. The redundant temperature elements have a horizontal separation of approximately 8 ' and are mounted on 24 " component cooling water pipes approximately 20 ' above the floor. Cables for the redundant head tank level transmitters are in proximity. Failures in these cables could initiate a spurious

lo-lo-head tank level isolation signal. This in turn would result in closure of the PCCW containment isolation valves. These valves are only required when it is necessary to maintain containment habitable for containment entry to manually operate the RHR isolation valves and the SI accumulator isolation valves. The circuitry for these valves is not affected by a fire in this area; hence, they would be operable from the MCR. Therefore, the spurious operation of these transmitters will not prevent safe shutdown. b) Chemical and Volume Control (CS) System This zone contains cables in tray required for operation of Train A valve CS -FCV-121, which provides one of the required hot standby charging flow paths. The redundant Train B valve SI -V139 cables are routed in barriered conduit in Fire Zone PAB -F-1A-Z and are separated from the Train A cables by concrete floors. For cooldown, the operators will manually align the Train B charging pump discharge and bypass valves (CS-V219 and CS -V220) to the seal injection flow path and throttle the bypass valve as required. This operator action can be delayed for up to of 4 hours into the event. This zone contains cables in barriered conduit for the charging to RCS isolation valve CS -V143. The cables for the redundant valve CS -V142 are not contained in this fire area. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-260 This zone contains cables routed in tray for the redundant boric acid tank level transmitters CS -LT-102 and CS-LT-106. These tank levels are only required once cooldown has been initiated. Should both transmitter cables be damaged by a fire, the operators can utilize the Train B level transmitter CS -LT-7464. This transmitter 's cable is contained in this fire zone. The indicator for this transmitter is located at the RSS panel in the Train B switchgear room (Fire Area: CB -F-1B-A). Should all level transmitters be unavailable, the operators will open th e cross-connect valve CS -V437 allowing charging pump suction from both boric acid tanks. The combined inventory of the two tanks is sufficient to complete the cooldown thus eliminating the need for tank level monitoring. This zone contains cables routed in tray and conduit for the redundant boric acid pumps CS -P-3A and CS -P-3B and for the valve CS -V426. Should both pumps or the valves be damaged by a fire, the operator will establish a gravity path from the BAT 's to the charging pump suction by the repositioning of manual valves in the boric acid pump room (Fire Zone PAB -F-2B-Z). Some of these valves are also required to cross -connect the boric acid tanks in response to a loss of level indication (see above discussion). These valves are not required to be operated until boric acid is required for shutdown reactivity. This would not be required for up to four hours into the event. This zone contains cables routed in tray and conduit for the Train A charging pump CS-P-2A. The cable for the redundant Train B pump CS -P-2B are routed in a barriered conduit in Fire Zone PAB -F-1A-Z. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-261 The zone contains cables routed in tray and conduit for the redundant valves CS -LCV-112B, CS-LCV-112D, CS-LCV-112C and CS -LCV-112E. The cables for valves CS-LCV-112C and CS -LCV-112E are routed in barriered conduits. The only exception is at an interference with fire detectors where the one -hour wrap is reduced to allow air flow to the detector. At the point of the reduced one -hour wrap, there is a minimum of 20 ' of horizontal separation to functionally redundant cables. See additional CS system discussion on CS -LCV-112B, CS-LCV-112C, CS-P-2A and CS -P-2B in the General Area Analysis, Section B.1.g.

This zone contains cables for CS-FCV-110A, -111A, -110B, -111B. Spurious opening of these valves may divert boric acid from the reactor coolant system affecting cold shutdown reactivity control, or result in an unplanned dilution affecting hot standby and cold shutdown reactivity control. The operators isolate the diversion flow by tripping the control circuit power supply breaker to close CS -FCV-110B & -111B (valves fail closed). The operators isolate the dilution flow by closing

CS-LCV-112C using the main control board control switch. This zone contains cables routed in trays for valve CS-V196. The cables for the redundant Train B valve CS-V197 are routed in a barrier conduit in Fire Zone PAB-F-1A-Z. c) Containment Enclosure Air Handling (EAH) System The cables for the redundant fans EAH -FN-5A and EAH-FN-5B, are routed in tray and conduits in the same area. All the Train B fan cables are routed in barriered conduits, which are separated from the Train A cables by a minimum of 18 '. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-262 Cables for redundant equipment vault return fans EAH-FN-31A and EAH -FN-31B are routed in trays and conduits in proximity to one another. These fans are required to maintain the equipment vaults habitable for entry if manual operations are required to place RHR into operation for cold shutdown. A fire in the PAB fire area will not prevent operation from the MCR of any equipment necessary for RHR operation; hence, habitability of the equipment vaults is not required. Analysis and field testing has confirmed that the containment enclosure supply fans EAH-FN-5A and EAH-FN-5B are sufficient to maintain the equipment vaults below the equipment 's qualified temperatures. d) Electrical Distribution Emergency (EDE) System All cables are Train A. The functionally redundant cables are located in other fire areas. e) PAB Air Handling (PAH) System Cables and equipment for outboard isolation dampers (PAH-DP-35A and PAH -DP-36A and inboard isolation dampers PAH -DP-35B and PAH -DP-36B are routed in trays and conduits in proximity to one another. Under normal operation both outboard and both inboard dampers are open. If both outboard or both inboard dampers go closed, the Containment Enclosure Air Handling (EAH) system operates in recirculation mode. The normal and recirculation modes for EAH system operation both satisfy

the safe shutdown function. If the outboard dampers and the inboard dampers operate independently such that either the supply or the exhaust path but not both are isolated, there could be an air flow problem in EAH system.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-263 Outboard dampers are powered from a single Train A power supply. Inboard dampers are powered from a single Train B power supply. The circuit design for the outboard and inboard dampers is such that a spurious signal in either or both circuits will cause both outboard and inboard dampers to operate together, either both open (normal mode) or both closed (recirculation mode). The redundant PAH fans (PAH -FN-42A and PAH-FN-42B) and dampers (PAH -DP-43A, PAH-DP-357, PAH-DP-43B and PAH -DP-358) are in proximity. The fans and dampers are inside separate metal enclosures located approximately 15 ' above the floor. The Train B fan and damper cables are routed in barriered conduits. The only exception to the barrier is short lengths of flexible conduit whose wrapping would interfere with damper

operator PAH -DP-358. There are no cable trays in the vicinity of the fans and dampers. The only in situ combustibles in the vicinity are in the PCCW pumps which are separated from the fans and dampers by greater than 20 ' horizontally and the monorail crane hoist. These fans are not needed unless the main ventilation system is lost due to the loss of off -site power or unless the temperature in the immediate area exceeds 40C (104F). The redundant temperature switches PAH -TSH-5391 and PAH-TSH-5393 and conduits containing their cables are located in proximity. Failure of these switches or their cables could prevent operation of fans PAH -FN-42A and PAH-FN-42B. Should the switches or cables fail, the operators can isolate the affected portion of the circuit at the RSS facilities in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A) and restart the fans.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-264 f) Service Water (SW) System This zone contains cables routed in tray for the Train A pumps SW-P-11A and SW -P-11C and valve SW -V54. The redundant Train B pumps and valve cables are routed in a barriered conduit in Fire Zone PAB -F-1A-Z which is separated from this zone by an intervening concrete floor. The cables for redundant valves SW -V4, SW-V16, SW-V5 and SW-V18, are located in the same fire zone. These valves may be required to reposition to isolate secondary component cooling water or for DG cooling. The Train B valves SW -V5 and SW -V18 cables are routed in barriered conduits and are separated from the Train A cables by greater than 30' horizontally. There are no cable trays or other in situ combustibles in the vicinity of Train B conduits. The cables for redundant valves SW -V-15 and SW -V17 are located in the same fire zone. These valves are normally in their safe shutdown position to provide cooling to the PCCW heat exchangers. In addition, the circuit breaker for

SW-V17 is administratively controlled off so the valve cannot spuriously close. If SW -V15 spuriously closes, SW-V17 is still open to provide the Train B PCCW heat exchanger cooling function. Redundant valves SW -V20, SW-V34 and SW -V19, SW-V23 are located in the same fire zone. Operators for valves SW -V34 and SW -V23 are approximately 5 ' above floor Elevation 25 '-0" and operators for valves SW -V20 and SW-V19 are approximately 10' above floor Elevation 25'-0". The redundant valves are separated by approximately 16 ' horizontally. There are no cable trays in the vicinity of the valves. The only in situ combustibles in the vicinity are the PCCW pumps which are separated from the Train A valves by greater than 16 ' horizontally. The valves are in Safe Shutdown position. The operators will prevent spurious operation by tripping the power supply breakers at the Train A and Train B Switchgear Rooms (Fire Area: CB -F-1A-A and CB-F-1B-A). SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-265 For the other Train A cables routed in this zone, the redundant cables and equipment are contained in other fire areas. g) Service Water Air Handling (SWA) System All cables are Train A. The redundant functionally cables are located in other fire areas. 3) Summary For the CC system above, the routing of the Train B cables in conduit with a one -hour, fire -rated barrier; the spatial separation; and the provision of the sprinkler system, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. For the CS system charging pumps and the related CS and SI valves above, the routing of the Train B cables in conduit with a

one-hour, fire -rated barrier and the provision of suppression in the area of the trays and the PCCW pumps, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. For the CS system transmitters, boric acid pumps and related valve above, the provision of a manual valve alignment capability that is not required for up to four hours into the event satisfies the safe shutdown requirements. Also, the capability to isolate the boric acid diversion flow by tripping the control circuit power supply breaker and isolate the dilution flow using the main control board control switches satisfies the safe shutdown requirements. For the EAH system supply fans above, the routing of Train B cables in conduit with a one -hour, fire -rated barrier and the provision of suppression in the area of the trays and the PCCW pumps, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. For the EAH system return fans above, the safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-266 For the PAH dampers above, the safe shutdown requirements are satisfied. For the PAH fans and related dampers above, the routing of the Train B cables in conduits with a one -hour, fire -rated barrier; the height of the fans off the floor; the lack of combustibles in the area of the fans and the fact that a fire in the area could not cause loss of offsite power, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. For the PAH temperature switches above, the safe shutdown requirements are satisfied. For the SW system above, the routing of the Train B cables in a conduit with a one -hour, fire -rated barrier; the spatial separation and the provision of the sprinkler system, provide acceptable fire protection and provide protection equivalent to the technical requirement of Appendix R. For the EDE and SWA systems above, the Appendix R separation requirements are satisfied.

g. Fire Zone PAB

-F-3A-Z (Tabulation 3.2.7.71)

1) Specific Zone Analysis This zone at Elevation 53

'-0" of the PAB is bounded by concrete floor, ceiling and walls (North, East and West) and is contiguous to fire zone PAB -F-3B-Z to the South. The southern boundary consists of a full height partition wall. There are penetrations for tray, ducts and pipes to other fire zones. The zone is approximately 53 ' long by 75 ' wide by 26 ' high with a floor area of 4000 sq. ft. and a volume of 103,400 cu. ft. Combustibles are limited to 1.0 gallon of oil for a fire loading of 150,000 Btu and cables in open trays for a total fire loading of 3000 Btu per sq. ft. of floor area. Detectors are provided throughout the zone.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-267 2) System Analyses a) Primary Component Cooling Water (CC) System Redundant transmitters and cables for head tank level logic are in proximity.

The circuitry for these valves is not affected by a fire in this area; hence they would be operable from the MCR. Therefore, the spurious operation of these transmitters will not prevent safe shutdown. b) Chemical and Volume Control (CS) System This zone contains cables routed in tray for the Train A valves CS-LCV-112B and CS-LCV-112D. The Train B cables are routed in barriered conduits in fire zone PAB-F-3B-Z. See additional CS system discussion on CS -LCV-112B, CS-LCV-112C, CS-P-2A and CS -P-2B in the General Area Analysis, Section B.1.g. This zone contains cables for CS-FCV-110A, -111A, -110B, -111B. Spurious opening of these valves in conjunction with spurious start of boric acid transfer pump or reactor makeup water pump may divert boric acid from the reactor coolant system affecting cold shutdown reactivity control, or result in an unplanned dilution affecting hot standby and cold shutdown reactivity control. The operators isolate the diversion flow by closing

CS-FCV-110B & -111B using the main control board control switches. The operators isolate the dilution flow by closing CS -LCV-112C using the main control board control switch. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-268 c) Service Water (SW) System This zone contains Train A valves SW -V15 and SW -V16 and cables for Train A valve SW -V4. Also contained in this zone are the redundant Train B valves SW -V17 and SW-V18 and cables for valve SW -V5. Redundant valves SW -V15 and SW -V17 are in the Safe Shutdown position. In addition, the circuit breaker for SW-V17 is administratively controlled off so the valve cannot spuriously close. If SW -V15 spuriously closes, SW-V17 is still open to provide the Train B PCCW heat exchanger cooling function. For conservatism, the operators will prevent further spurious operation by tripping the SW -V15 power supply breaker in the Train A switchgear room (Fire Area: CB -F-1A-A). Redundant diesel generator jacket water heat exchanger valves SW -V16 and SW-V18 are normally closed and are required to open for operation of the diesel generators.

De-energizing the solenoids will open the valves. If SW-V16 or SW -V18 spuriously closes, SW to the respective train DG would be isolated. The other train DG

would still be available. Also, a fire in this area does not cause a loss -of-offsite power. To prevent further spurious operation, the operators will trip the valves ' power supply breakers in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The Train A cables for valve SW -V4 are routed in trays and conduit. The trays and conduit are a minimum of 10 ' above floor Elevation 53 '-0". The Train B cables for valve SW-V5 are routed in barriered conduits. The Train A and Train B raceways are separated by greater than 25 '. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-269 3) Summary For the CC system above, the safe shutdown requirements are satisfied. For the CS system above, the routing of the Train B cables in conduit with a one -hour, fire rated barrier in another fire zone and considering the low combustibles loading in the zone, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III G.2.c, "in addition to one (1) hour fire barrier, an automatic fire suppression system shall be installed ", has been approved. Also, the capability to isolate the boric acid diversion flow and the dilution flow using the main control board control switches satisfies the safe shutdown requirements. For the SW system above, the routing of the Train B cables in a conduit with a one -hour, fire -rated barrier; the spatial separation; the disabling capabilities in another fire area; and considering the low combustibles loading in the zone, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III G.2.c, "in addition to one (1) hour fire barrier, an automatic fire suppression system shall be installed ", has bee n approved.

h. Fire Zone PAB

-F-3B-Z (Tabulation 3.2.7.72)

1) Specific Zone Analysis This zone at Elevation 53

'-0" of the PAB is bounded by concrete floor, ceiling and walls (South, East and West) and is contiguous to fire zone PAB -F-3A-Z to the North. The northern boundary consists of a full height partition wall. There are penetrations for ducts and pipes to other fire zones. The zone is approximately 88 ' long by 75 ' wide by 26 ' high with a floor area of 6500 sq. ft. and a volume of 168,200 cu. ft.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-270 Combustibles are limited to 71 pounds of plastic (fiberglass ladders) for a fire loading of 923,000 Btu, 0.5 gallon of oil for a fire loading of 75,000 Btu, 50 pounds of Class A material for a fire loading of 400,000 Btu for a total fire loading of 1602 Btu per sq. ft. of floor area. See "Fire Protection Program Evaluation and Comparison to Branch Technical Position APCSB 9.5 -1 Appendix A" for the analysis of 6600 lbs. of charcoal in CAP-F-40. Detectors are provided throughout the zone.

2) System Analysis a) Primary Component Cooling Water (CC) System Redundant transmitters and cables for head tank level logic are in proximity. Failures in these transmitters or cables could initiate a spurious lo

-lo head tank level isolation signal. This in turn would result in closure of the PCCW containment isolation valves. These valves are only required when it is necessary to maintain containment habitable for containment entry to manually operate the RHR isolation valves and the SI accumulator isolation valves. The circuitry for these valves is not affected by a fire in this area; hence, they would be operable from the MCR. Therefore, the spurious operation of these transmitters will not prevent safe shutdown. b) Chemical and Volume Control (CS) System The redundant volume control tank isolation valves

CS-LCV-112B and CS -LCV-112C are located in the same fire area. The valves are in separate concrete cells with concrete walls and a solid controlled access door between them. There are no in situ combustibles or cables in trays in the cells. The cables for the Train B valve CS-LCV-112C are routed in barriered conduits. See additional CS system discussion on CS -LCV-112B, CS-LCV-112C, CS-P-2A and CS -P-2B in the General Area Analysis, Section B.1.g.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-271 This zone contains cables for the redundant RWST suction valves CS -LCV-112D and CS -LCV-112E. These cables are part of a circuit that will automatically open the opposite train RWST valve if a VCT valve is not full open (i.e., spuriously closes). Since the VCT valves do not spuriously close for a fi re in this zone, the automatic open circuit is not required. The automatic open circuit is supplied from a separate circuit, i.e., not the RWST MOV control circuit, so failure of these cables does not affect the ability to manually open the RWST valves as part of transferring charging pump suction from the VCT to the RWST. This zone contains cables for

CS-FCV-110A, -111A, -110B, -111B. Spurious opening of these valves in conjunction with spurious start of a boric acid transfer pump or reactor makeup water pump may divert boric acid from the reactor coolant system affecting cold shutdown reactivity control, or result in an unplanned dilution affecting hot standby and cold shutdown reactivity control. The operators isolate the diversion flow by closing CS-FCV-110B & -111B using the main control board control switches. The operators isolate the dilution flow by closing CS -LCV-112C using their main control board control switch.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-272 3) Summary For the CC system above, the safe shutdown requirements are satisfied. For the CS system above, the routing of the Train B cables in a one-hour, fire -rated barrier; the separation between the valves; the absence of in situ combustibles in the cells; and considering the low combustibles loading in the zone, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R Paragraph III G.2.c, "in addition to 1 hour fire barrier, an automatic fire suppression system shall be installed ", has been approved. Also, the capability to isolate the boric acid diversion flow and the dilution flow using the main control board control switches satisfies the safe shutdown requirements. C. Evaluation Deviations from the Appendix R, Paragraph III.G.2 separation requirements exist in the Primary Auxiliary Building fire zones PAB -F-1A-Z, PAB-F-1J-Z, PAB-F-1K-Z, PAB-F-2A-Z, PAB-F-2B-Z, PAB-F-2C-Z, PAB-F-3A-Z and PAB-F-3B-Z. These deviations are justified based on the above analyses and our assertion that additional modifications would not enhance fire protection safety.

The redundant Train B safe shutdown cables are located in fire area DCT -F-3B-0 and other fire areas. The Appendix R separation requirements are satisfied.

2. PCCW Head Tank level Transmitters CC

-LT-2172-1, 2, 3; CC -LT-2272-1, 2, 3; CC-LT-2192-1, 2, 3, CC -LT-2292-1, 2, 3 Cables for the redundant head tank level transmitters are in proximity. Failures in these cables could initiate a spurious lo -lo-head tank level isolation signal. This in turn would result in closure of the PCCW containment isolation valves. These valves are only required when it is necessary to maintain containment habitable for containment entry to manually operate the RHR isolation valves and the SI accumulator isolation valves. The circuitry for these valves is not affected by a fire in this area; hence, they would be operable from the MCR. Therefore, the spurious operation of these transmitters will not prevent safe shutdown. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-280 3. Component Cooling Water Pumps CC -P-11A, CC-P-11C and Component Cooling Water Containment Isolation Valves CC -V175, CC-V257 A fire could cause loss of all PCCW to containment. It should be noted, however, that these valves are required to remain operable only for containment entry when manual operation of the safety injection isolation valves SI -V3, SI-V17, SI-V32 and SI-V47 and the reactor coolant - RHR isolation valves RC -V22, RC-V23, RC-V87 and RC -V88 are required. Cables for these valves are not routed through this fire area; hence, the valves would be operable from the main control room or the RSS control panels and containment entry would not be required. The safe shutdown requirements are satisfied.

4. RHR Heat Exchanger Outlet Valves CC

-V145, CC-V272 Cables for redundant valves CC -V145 and CC -V272 are routed in proximity to one another. The valves are normally open to their shutdown cooling position and their position is inconsequential until the plant is cooled down to 350F and the RH system is placed in operation. At that time, it is necessary to assure that the valve supplying PCCW to the operational RH train is opened. This can be accomplished manually if required in the appropriate equipment vault. Manual operation can be delayed as much as 9 hours into the event. Therefore, no fire protection other than the existing separation is needed. The provision of a capability to position the valve outside the fire area satisfies the safe shutdown requirements.

5. Charging Pump Discharge Valve CS

-FCV-121 This zone contains cables in tray required for operation of Train A valves

CS-FCV-121, which provides one of the required hot standby charging flow paths. The redundant Train B SI-V139 cables are located in Fire Area DCT-F-3B-0. For cooldown, the operators will manually align the Train B charging pump discharge and bypass valves (CS -V219 and CS -V220) to the seal injection flow path and throttle the bypass valve as required. This operator action can be delayed for up to of 4 hours. The Appendix R separation and safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-281 6. Boric Acid Tank Level Transmitter CS -LT-102, CS-LT-106 This zone contains cables routed in tray for the redundant boric acid tank level transmitters CS -LT-102 and CS -LT-106. These tank levels are only required once cooldown has been initiated. Should both transmitter cables be damaged by a fire, the operators can utilize the Train B level transmitter CS -LT-7464 whose cable is not routed through this fire area. The indicator for this transmitter is located at the RSS panel in the Train B switchgear room (Fire Area: CB -F-1B-A). The provision of a redundant transmitter with its cable routed in another fire area satisfies the safe shutdown requirements.

7. Seal Injection Isolation Valves CS

-V154, CS-V158, CS-V162 and CS -V166 Under normal conditions, the seal injection isolation valves CS -V154, CS-V158, CS-V162 and CS -V166 are utilized for the seal injection flow path. Spurious closure of one of these valves will not prevent safe shutdown. The operators will prevent further spurious operations by tripping the power supply breakers in the Train A switchgear room (Fire Area: CB -F-1A-A). The safe shutdown requirements are satisfied.

8. RC Pump Seal Water Isolation Valve CS

-V167 Valve CS-V167 is a normally open valve which should remain open for safe shutdown. Spurious isolation of this Train A valve could result in loss of RC inventory through the upstream relief valve. This inventory is directed to the PRT and is therefore, non -recoverable. To preclude this loss of inventory, functionally redundant isolation capability is provided by the RC pump seal return lines by means of Train A valves CS -V10, CS-V28, CS-V44, and CS -V59. The cables, controls and equipment required for operation of valves CS -V10, CS-V28, CS-V44, and CS -V59, are not contained in this fire area. The Appendix R separation requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-282 9. BAT to Charging Pump Isolation Valve CS -V426 Valve CS-V426 is a normally closed valve which is opened to provide a path from the boric acid tanks to the charging pump suction. This path is required to begin cooldown. In the event that this valve is inoperable, the operators can provide a redundant path by manually positioning valves in the boric acid tank room (Fire Area: PAB -F-2B-Z). The operators can maintain the plant in hot standby for the time required to perform this manual action. The safe shutdown requirements are satisfied.

10. SI-CS Suction Cross Connection Valves CS

-V460, CS-V461, CS-V475 Valves CS -V460, CS-V461 and CS -V475 are located in proximity. Prior to beginning cooldown the normally closed CS -V460 and CS -V461 valves should remain closed or the functionally redundant valve CS -V475 should be closed. The isolation of this path will prevent loss of boric acid tank inventory to the RWST during cooldown. In the event of a spurious valve operation which renders this flow path open, the plant can be maintained in hot standby for as long as 4 hours. Should the operators desire to initiate the cooldown sooner than 4 hours, a gravity feed can be established from the boric acid tanks to the charging pumps. As the BAT head is lower than that required to return inventory to the RWST, there would be no loss of BAT inventory through this path and the position of these valves would be inconsequential. The safe shutdown requirements are satisfied.

11. Containment Enclosure Isolation Damper, PAH

-DP-35A, PAH-DP-36A, PAH-DP-35B, PAH-DP-36B Cables for outboard isolation dampers PAH -DP-35A and PAH -DP-36A and inboard isolation dampers PAH -DP-35B and PAH -DP-36B are routed in trays and conduits in proximity to one another. Under normal operation both outboard and both inboard dampers are open. If both outboard or both inboard dampers go closed, the Containment Enclosure Air Handling (EAH) system operates in recirculation mode. The normal and recirculation modes for EAH system operation both satisfy the safe shutdown function. If the outboard dampers and the inboard dampers operate independently such that either the supply or the exhaust path but not both are isolated, there could be an air flow problem in EAH system. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-283 Outboard dampers are powered from a single Train A power supply. Inboard dampers are powered from a single Train B power supply. The circuit design for the outboard and inboard dampers is such that a spurious signal in either or both circuits will cause both outboard and inboard dampers to operate together, either both open (normal mode) or both closed (recirculation mode). The safe shutdown requirements are satisfied.

12. RHR Isolation Valves RC

-V22, RC-V23, RC-V87, RC-V88 Cables for redundant valves are located in proximity. As the RHR isolation valves are permanently disabled in the closed position, failures in the cables cannot cause a spurious operation. Valves RC -V87 and RC -V88 are required to be opened for cooldown below 350F when the RH system is placed in operation. Should the cable damage be such that the valves cannot be operated from the MCR, the affected portion of the circuit can be isolated at the RSS panels in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A) and the valves repositioned for safe shutdown. The safe shutdown requirements are satisfied.

13. RHR Heat Exchanger Outlet Flow Control and Bypass Flow Control Valves RH-FCV-618, RH-HCV-606, RH-FCV-619, RH-HCV-607 Cables for the redundant flow control valves are routed in proximity. The RH-HCV-606 and RH

-HCV-607 valves are normally closed and are required to open whereas the RH -FCV-618 and RH -FCV-619 are normally open and are required to close. These valves are only required to operate when the RH system is placed in operation (cold shutdown). The valves have air operators controlled by dc solenoids. These solenoids when deenergized vent the air from the operators and cause the valves to fail to their safe shutdown position. In the event this positioning cannot be performed in the MCR, the operators will position these valves by tripping the power supply breakers in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-284 14. RH Pump to Cold Leg Isolation Valves RH -V14, RH-V26 Cables for redundant valves RH -V14 and RH -V26 are routed in proximity. These valves are normally open valves which are required to remain open for RH systems operation (cold shutdown). If one of the valves spuriously closes, the operators will prevent further spurious operation of these valves by tripping the power supply breakers in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The safe shutdown requirements are satisfied.

15. RH Pump to Hot Leg Isolation Valves RH

-V70, RH-V32 Cables for redundant valves RH -V70 and RH -V32 are routed in proximity. These valves are normally closed valves which are required to remain closed for RH system operation (cold shutdown). If one of the valves spuriously opens, the operators will prevent further spurious operation of these valves by tripping the power supply breakers in the Train A and Train B switchgear rooms (Fire Areas: CB-F-1A-A and CB-F-1B-A). The safe shutdown requirements are satisfied.

16. RH Heat Exchanger to CS/SI Pump Isolation Valves RH-V35, RH-V36 Cables for the redundant valves RH

-V35 and RH -V36 are routed in proximity. Valves RH -V35 and RH -V36 are normally closed and their position is inconsequential until the plant is cooled down to 350F and the RH system is placed in operation. At that time it is necessary to assure that the valves remain closed. Should one of the valves open spuriously the operators can disable its power supply in either the Train A or Train B switchgear rooms (Fire Areas: CB-F-1A-A or CB-F-1B-A) and manually reposition the valves located in the equipment vaults (Fire Zone RHR -F-4B-Z or RHR-F-2A-Z). Manual operation of the valves can be delayed as much as 9 hours into the event. Therefore, no fire protection other than the existing separation is needed. The provision of a capability to mitigate the spurious operation of the valves outside the fire area satisfies the safe shutdown requirements.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-285 17. Containment Pressure Transmitters SI -PT-936, SI-PT-937 Redundant channels of containment pressure cables are located in proximity. Spurious operation of these channels will initiate containment spray and containment isolation Phase B. The operators will have the capability to terminate these protective actions by use of manual reset switches. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CB-F-1A-A and CB-F-1B-A). The provision of a capability to mitigate the spurious operation of the pressure transmitters outside the fire area satisfies the safe shutdown requirements.

18. Volume Control Tank Isolation Valve CS

-LCV-112B and Charging Pump CS-P-2A & CS-P-2B Volume control tank (VCT) isolation valves CS -LCV-112B & -112C are normally open to provide a suction path from the VCT to the normally operating charging pump (CS -P-2A or -2B). These valves must stay open until RWST valve CS-LCV-112D or -112E is manually opened to provide a charging pump suction path from the RWST, or the boric acid tanks are manually aligned as a charging pump suction source. Spurious closure of a VCT isolation valve caused by a hot short would interrupt suction flow to the operating charging pump

causing it to be damaged. If the standby charging pump has cables in the same area then its operation can also be degraded. The result would be no charging system flow. Since this fire area contains cables for CS -LCV-112B and CS -P-2A, this condition is potentially applicable for the system alignment with CS -P-2A the standby pump and CS -P-2B the operating pump. The CS-LCV-112B circuit design prevents spurious valve closure from hot shorts as follows. The field cable conductors for the motor control center (MCC) contactor close coil circuit are in different cables than the 120 V "hot" circuit conductors eliminating the hot short failure mode within the cables. Cable-to-cable hot shorts need not be postulated for thermoset cable insulation as used at Seabrook. Since CS -LCV-112B will not spuriously close, CS -P-2B as the operating charging pump will not be damaged. Since charging flow is available, the safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-286 19. Boration/Dilution Flow Control Valves, CS -FCV-110A, -111A, -110B, -111B This area contains cables for CS -FCV-110A, -111A, -110B, -111B. Spurious opening of these valves in conjunction with spurious start of a boric acid transfer pump or reactor makeup water pump may divert boric acid from the reactor coolant system affecting cold shutdown reacivity control, or result in an unplanned dilution affecting hot standby and cold shutdown reactivity control. The operators isolate the diversion flow by closing CS -FCV-110B and -111B using the main control board control switches. The operators isolate the dilution flow by closing CS -LCV-112C using the main control broad switch. The safe shutdown requirements are satisfied. C.

SI-CS Suction Cross Connection Valves CS -V461, CS-V475 Valves CS -V461 and CS-V475 are located in proximity. Prior to beginning cool down the normally closed valve CS -V461 should remain closed or the functionally redundant valve CS -V475 should be closed. The isolation of this path will prevent loss of boric acid tank inventory to the RWST during cooldown. In the event of a spurious valve operation, which renders this flow path open, the plant can be maintained in hot standby for as long as 4 hours. Should this area be inaccessible due to the fire or should the operators desire to initiate the cooldown sooner than 4 hours, a gravity feed can be established from the boric acid tanks to the charging pumps. As the BAT head is lower than that required to return inventory to the RWST, there would be no loss of BAT inventory through this path and the position of these valves would be inconsequential. The safe shutdown requirements are satisfied.

3. RHR Isolation Valves RC

-V22, RC-V87, RC-V88 Cables, for functionally redundant valves are located in proximity. As the RHR isolation valves are permanently disabled in the closed position, failures in the cables cannot cause a spurious operation. Valve RC -V22 is required to be opened for cool down below 350F when the RH System is placed in operation. Should the cable damage be such that the valve cannot be operated from the MCR, the affected portion of the circuit can be isolated at the RSS panel in the Train B switchgear room (Fire Area: CB -F-1B-A) and the valve repositioned for safe shutdown. The safe shutdown requirements are satisfied.

RH Heat Exchanger to CS/SI Pump Isolation Valves RH -V35 and RH -V36 and SI Isolation Valve SI -V89 Cables for the redundant valves RH -V35 and RH -V36 are routed in proximity to one another. Valves RH -V35 and RH -V36 are normally closed and their position is inconsequential during all modes of plant operation with the exception of cooldown below 350F when the RH System is placed in operation. At that time, it is necessary to insure that the valves remain closed. Should valve RH -V35 open spuriously, the operators can disable its power supply in the Train A switchgear room (Fire Area: CB -F-1A-A) and manually reposition the valves located in the Equipment Vault - Train A (Vault #1) (Fire Zone: RHR -F-4B-Z). Manual operation of the valve can be delayed as much as 9 hours into the event. Therefore, no fire protection other than the existing separation is needed.

To preclude this loss of inventory, functionally redundant isolation capability is provided by the RC pump seal return lines by means of Train A valves CS -V10, CS-V28, CS-V44, and CS -V59 and the excess letdown line by means of normally closed, fail closed valves CS -V175 or CS-V176. The cables, controls and equipment required for operation of valves CS-V10, CS-V28, CS-V44, CS-V59, CS-V175 and CS -V176 are not contained in this fire area. The Appendix R separation requirements are satisfied.

4. SI-CS Suction Cross Connection Valves CS

-V460, CS-V461, CS-V475 Valves CS -V460, CS-V461 and CS -V475 are located in proximity. Prior to beginning cooldown the normally closed CS -V460 and CS -V461 valves should remain closed or the functionally redundant valve CS -V475 should be closed. The isolation of this path will prevent loss of boric acid tank inventory to the RWST during cooldown. In the event of a spurious valve operation which renders this flow path open, the plant can be maintained in hot standby for as long as 4 hours. Should this area be inaccessible due to the fire or should the operators desire to initiate the cooldown sooner than 4 hours, a gravity feed can be established from the boric acid tanks to the charging pumps. As the BAT head is lower than that required to return inventory to the RWST, there would be no loss of BAT inventory through this path and the position of these valves would be inconsequential. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-295 5. RHR Isolation Valves RC -V22, RC-V23, RC-V88 Cables for redundant valves are located in proximity. As the RHR isolation valves are permanently disabled in the closed position, failures in the cables cannot cause a spurious operation. Valve RC -V88 is required to be opened for cooldown below 350F when the RH system is placed in operation. Should the cable damage be such that the valve cannot be operated from the MCR, the affected portion of the circuit can be isolated at the RSS panel in the Train A switchgear room (Fire Area: CB -F-1A-A) and the valve repositioned for safe shutdown. The safe shutdown requirements are satisfied.

6. RH Heat Exchanger to CS/SI Pump Isolation Valves RH

-V35, RH-V36 and SI Isolation Valves SI -V90, SI-V93 Cables for the redundant valves RH -V35 and RH -V36 are routed in proximity to one another. Valves RH -V35 and RH-V36 are normally closed and their position is inconsequential during all modes of plant operation with the exception of cooldown below 350F when the RH System is placed in operation. At that time, it is necessary to assure that valve RH -V36 remains closed. Should valve RH-V36 open spuriously, the operators can disable its power supply in the Train B switchgear room (Fire Area: CB -F-1B-A) and manually reposition the valve located in the equipment Vault Train B (Vault #2) (Fire Zone: RHR-F-2A-Z). Manual operation of the valve can be delayed as much as 9 hours into the event. Therefore, no fire protection other than the existing separation is needed. The provision of a capability to mitigate the spurious operation of the valves outside the fire area satisfies the safe shutdown requirements. C. Evaluation The safe shutdown requirements and Appendix R separation requirements are satisfied.

Analysis Redundant valves CS -LCV-112D and CS -LCV-112E are located in the same fire area. The cables for VCT isolation valves CS -LCV-112B and CS -LCV-112C, are also located in this fire area. These are normally open valves. A fire in this area will prevent opening the normally closed RWST to charging pump isolation valves from the control room. The normally open VCT isolation valves may experience a loss of control power but can not spuriously close as described below. A fire in this area does not affect the normal charging, letdown, and boric acid makeup functions so safe shutdown can be achieved and maintained using a charging pump aligned to the VCT through CS -LCV-112 B & -112C. The RWST is not needed for this normal shutdown so the inability to open CS -LCV-112D & -112E does not affect safe shutdown. If there was a need to use the RWST, the RWST valves could be manually opened, and the VCT isolation valves could be closed from the RSS panels or manually closed. Volume control tank (VCT) isolation valves CS -LCV-112B & -112C are normally open to provide a suction path from the VCT to the normally operating charging pump (CS-P-2A or -2B). These valves must stay open to provide a charging pump suction path from the VCT. Spurious closure of a VCT isolation valve caused by a hot short would interrupt suction flow to the operating charging pump causing it to be damaged. If the standby charging pump has cables in the same area then its operation can also be degraded. The result would be no charging system flow. Since this fire area does not contain cables for CS -P-2A or CS-P-2B, this condition is not applicable to this fire zone.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-311 Furthermore, the CS -LCV-112B and -112C circuit design prevents spurious valve closure from hot shorts as follows. The field cable conductors for the motor control center (MCC) contactor close coil circuit are in different cables from the 120 V "hot" circuit conductors eliminating the hot short failure mode within the cables. Cable -to-cable hot shorts need not be postulated for thermoset cable insulation as used at Seabrook. Since

CS-LCV-112B and -112C will not spuriously close, CS-P-2A or -2B as the operating charging pump will not be damaged. C. Evaluation The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 14 Section 3.3 Page 3.3-1 3.3 ALTERNATIVE SAFE SHUTDOWN USING REMOTE SAFE SHUTDOWN FACILITIES 3.3.1 General Remote safe shutdown (RSS) is a design feature which allows plant shutdown from locations other than the main control room in the event of a fire or other condition which requires evacuation of the main control room. The fire areas of concern are the main control room, control room HVAC room, and the cable spreading room. Remote safe shutdown contains the necessary complement of systems and equipment required to satisfy the performance goals delineated in Appendix R, Paragraph III.L.2. Technical Specification (T/S) 3/4.3.3.5 requires surveillance testing of selected equipment used for safe shutdown from outside the Control Room at Remote Safe Shutdown (RSS) locations. The required equipment is listed in Table 3.3 -9. The selection criteria for the Transfer Switch/Control Circuit portion of the table is the primary equipment which has remote/local selector switches and is required to perform the reactor coolant system inventory and pressure control, reactivity control, and decay heat removal functions to achieve and maintain hot standby. For Appendix R shutdown, only one train of equipment (safety or non -safety related) is required; redundancy is not a requirement. Seabrook is a hot standby safe shutdown design basis plant (see UFSAR Section 5.4.7.2.i). Support equipment, and equipment required only to achieve and maintain cold shutdown, are not required to be included in the T/S table. Process monitoring instruments also have surveillance requirements. 3.3.2 Safe Shutdown Control Locations Normally safe shutdown will be accomplished from the main control room, utilizing the safe shutdown equipment along with other equipment which may be available to the operators. Upon detection of a fire, the fire brigade will be dispatched to the affected area and a determination will be made as to the severity of the fire. If it is determined that the fire has a potential for impacting safe shutdown from the main control room, the operators will proceed with a planned evacuation of the main control room and manning of the Train B remote safe shutdown control panel (MM-CP-108B) and man the following remote safe shutdown (RSS) facilities as necessary:

a. Train B Switchgear Room (Switchgear E6, and various Unit Substations, Motor Control Centers (MCC) and Distribution Panels) and RSS Aux Panel in Electrical Tunnel B. b. Train A Switchgear Room (MM

-CP-108A, Switchgear E5, and various Unit Substations, Motor Control Centers (MCC), and Distribution Panels) and RSS Aux Panel in Electrical Tunnel A .

" refers to an action taken after receipt of a valid fire alarm in the main control room. The term "expeditious action " or "expeditiously " refers to an action taken quickly upon entry into the applicable safe shutdown procedure. These type actions are considered to be completed prior to a spurious operation of the equipment operated by the prompt and expeditious actions. Therefore, no associated timing calculation is required for these actions. 3.3.3 Safe Shutdown Functions for Hot Standby The following are equipment necessary for Hot Standby:

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 14 Section 3.3 Page 3.3-3 3.3.3.1 Reactor Coolant (RC) Inventory and Pressure Control To compensate for miscellaneous RC system leakage, RC pump seal leakage and cooldown volume shrink, portions of the chemical and volume control (CS) system including centrifugal charging pumps, boric acid transfer pumps, and a borated water supply, either the refueling water storage tank (RWST) or the boric acid tanks (BAT) are used. The injection path to the RC system will be either through the seal injection flow path or the high head injection flow path. The preferred seal injection path requires that a flow control valve (CS -FCV-121) and that a minimum of two of the four seal injection valves (CS -V154, CS-V158, CS-V162 or CS -V166) be operable. Additionally, the normal charging flow to the RC system is isolated. This can be accomplished by temporarily stopping a charging pump to prevent overfill of the pressurizer. It can also be accomplished by use of any one of two functionally redundant but non -credited valves (CS -V142 or CS -V143). Should the seal injection path not be operable e.g., due to spurious closure of a flowpath valve (CS-FCV-121), the high head injection flow path (SI -V138 or SI -V139) can be utilized initially to maintain hot standby by batch charging from the RWST to maintain pressurizer level. During cooldown as RC system pressure decreases, it is necessary to provide a flow restricted path to prevent charging pump cavitation. This is due to the limited flow capability from the BAT. If the high head injection path cannot be isolated at this time and/or if the flow controlled path through CS -FCV-121 is not operable, a capability is provided to manually align and throttle the charging pumps to the seal injection flow paths. The necessary operator actions and valve alignments are unique for each fire area where these flow paths are affected and are described in the analysis for each area. RC pump seal cooling is provided by a redundant thermal barrier cooling system. Should the redundant thermal barrier system not be available, the seals will be cooled by the seal injection capability. A control room or cable spreading room fire can result in a temporary loss of all cooling to the RCP seals. The operator action to accomplish restoration of cooling to the seals is to restore power to an emergency bus, restart of a thermal barrier cooling pump and a CC water pump. Then, a charging pump and SW pump are started for long term seal cooling via seal cooling, as well as inventory control. The operator action to restore RCP seal cooling is accomplished prior to the time that there would be potential damage to the seals. The reactor coolant pumps (RCPs) are stopped from the main control board prior to evacuating the main control room. Circuit analysis shows that the RCPs can not spuriously restart due to fire -induced cable damage. The RC system pressure is controlled by use of a portion of the RC system which includes the pressurizer heaters (Group A and B) to increase pressure and the pressurizer power operated relief

valves (PORV) which depressurize the RC system by discharging reactor coolant fluid to the pressurizer relief tank (PRT).

<4 hours, prior to commencement of plant cooldown Align BAT for makeup source
<4 hours, prior to commencement of plant cooldown 3.3.3.2  Reactivity Control Reactivity for hot standby at normal operating temperature (NOT) is provided by insertion of the control rods. Reactivity conditions required for cooldown and maintaining cold shutdown are provided by a portion of the chemical and volume control (CS) system which includes a centrifugal charging pump taking suction from the BAT

's. During cooldown, the borated source must be the BAT volume until expended to at least the point that the volume injected or a boron sample demonstrates that sufficient shutdown margin for cold shutdown has been achieved, at which time the RWST would be aligned. The credited path for boration is gravity feed with the RWSP isolated. The boric acid transfer pumps can be used if available. Considering worst case scenarios for spurious actuation of affected equipment, the required times for operator actions regarding reactivity control for safe shutdown from the remote safe shutdown facilities are provided below: Action Time Trip the Reactor Expeditiously Provide borated water from the BATs, via boric acid transfer pump or gravity feed.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 14 Section 3.3 Page 3.3-6 3.3.3.3 Decay Heat Removal The reactor coolant (RC) system temperature is controlled by use of portions of the feedwater (FW) system and the main steam (MS) system. The main steam safety/relief valves will maintain a heat dump capability. The steam generator water inventory is controlled by operating the motor driven emergency feedwater pump and associated emergency feedwater control valves. Inventory for the emergency feedwater is from the condensate storage tank. Long term water capability exists using a temporary connection between the suction of the emergency feed pumps and the fire protection system but is not required to meet Appendix R requirements. To assure main steam system integrity the MSIV 's and MSIV bypass are maintained closed. The MSIV bypass valves are normally locked closed and depowered with breakers locked open to preclude spurious opening. Decay heat transfer is made possible by natural convection flow in the RC System. Considering worst case scenarios for spurious actuation of affected equipment, the required times for operator actions regarding decay heat removal for safe shutdown from the remote safe shutdown facilities are provided below: Action Time Isolate MSIVs Expeditiously following a reactor trip Place the mode selector switches for the ASDVs to the closed position Prompt Gain Control of excessive Emergency Feedwater Flow 20 minutes Start motor driven EFW pump to preclude steam generator dry out 39 minutes Time allotted for operator actions to preclude emptying CO tank to accommodate RHR Cut -in, and ultimately achieve cold safe shutdown within 72 hours 9 hours; 4 hours at hot standby plus

3.3.3.5 Service Water The service water system will supply cooling water to the primary component cooling water system, diesel generators, and if required, fire protection system. Service water supply will be from the service water pumps taking suction from the tunnels to the ocean. Section 3.3.3.1 provides the required times for operator actions, based on worst case scenarios for spurious actuation. 3.3.3.6 Primary Component Cooling Water (CC) The CC system is utilized to maintain cooling water to the charging pumps, RH pumps, RH heat exchangers, and reactor coolant pumps (RCP) thermal barrier heat exchanger. The PCCW pumps, temperature control valves, and RCP thermal barrier cooling pumps are necessary for system operations. Section 3.3.3.1 provides the required times for operator actions, based on worst case scenarios for spurious actuation.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 14 Section 3.3 Page 3.3-8 3.3.3.7 Sampling Sampling of the reactor coolant system is not required at hot standby and cold shutdown conditions since make -up during cool -down will only be provided to the RCS from the boric acid tanks (two) which are maintained at 4 wt% boric acid. During all phases of cool -down, the core will be maintained to the shutdown margin greater than or equal to the limit specified in the Core Operating Limits Report (COLR). 3.3.3.8 Diesel-Generator Building Air Handling (DAH) The DAH system is utilized to maintain long -term habitability and equipment protection for the diesel-generator rooms. The DAH system includes the fans and dampers for air handling in these areas. 3.3.3.9 Containment Enclosure Air Handling (EAH) The EAH system is utilized to maintain long-term habitability of the mechanical penetration area, and provide equipment cooling in the charging pump rooms, and the hydrogen analyzer and electrical room. The EAH system includes the coolers, fans, and dampers required for air handling in these areas. 3.3.3.10 Emergency Feedwater Pumphouse Air Handling (EPA) The EPA system is utilized to maintain long -term habitability and equipment protection in the emergency feedwater pump building. The EPA system includes the fans and dampers required for air handling in this area. 3.3.3.11 Primary Auxiliary Building Air Handling (PAH) Portions of the PAH system are utilized to maintain long -term habitability and equipment protection in the PCCW area of the primary auxiliary building. The PAH system includes the fans and dampers required for ventilation in this area. 3.3.3.12 Service Water Air Handling (SWA) Portions of the SWA system are utilized for equipment protection in the SW pump house electrical control rooms. The SWA system includes the fans and dampers required for air handling in these areas. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 14 Section 3.3 Page 3.3-9 3.3.3.13 Electrical Distribution Emergency (EDE) Portions of the EDE system are required to power the various pumps, fans, valves, etc. required for safe shutdown. Included in the EDE system are the 4160 Volt ac emergency switchgear, 460 Volt ac emergency unit substations and motor control centers, the uninterruptible power supplies, 120 Volt ac vital distribution panels, 125 Volt dc batteries, battery chargers, and 125 Volt dc distribution panels. 3.3.3.14 Diesel-Generators (DG) The diesel -generators provide power to the electrical distribution emergency system upon loss of off-site power. The DG system includes the diesel, generators, control panels, engine -driven auxiliaries, fuel oil transfer pumps, starting air compressors and backup operating air compressors. 3.3.3.15 Safeguard Actuation System The safeguard actuation system could be actuated. A portion of this system is used to deactivate the system for recovery. 3.3.3.16 Communication The Gaitronics or radio systems are used to announce the fire event, dispatch the fire brigade, and to dispatch an NSO to perform local actions in the emergency diesel generator rooms. The Gaitronics system is also used to provide a fire alarm. Face -to-face communications is used to dispatch a control room operator (CRO) to the Train B switchgear room to perform local actions. A sound powered telephone loop (SPC) is provided for the CRO and NSO to communicate between the switchgear and the diesel generator rooms. Headsets or handsets are stored at these RSS locations for operator use. All actions required to achieve and maintain hot standby are taken in these areas. When field actions are required to commence cooldown, and achieve and maintain cold shutdown, an operator would: a) be dispatched to take the required action, b) go to the field and take the action, and c) then return and report the action completed. The RSS SPC loop also includes two SPC jacks in the RHR equipment vaults. Radios and Gaitronics are not credited but would be used as additional means of communications, if not damaged by the fire. 3.3.4 Safe Shutdown Functions for Cooldown The following equipment in addition to that which is listed in Section 3.3.3 are necessary for cooldown.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 14 Section 3.3 Page 3.3-10 3.3.4.1 Decay Heat Removal In addition to equipment discussed in Section 3.3.3.3, the steam generator atmospheric relief valves will be used for cooldown until the residual heat removal (RH) system can be used. The residual heat removal system will be the long term heat sink at the end of cooldown. An RH pump will be operated along with various control, manual and motor operated valves. 3.3.4.2 Sample System For cold shutdown, the operators will draw a manual sample from RH system to verify boron concentration before li ne-up to RCS. The operator will use manual valves in RH system. 3.3.5 Initial Operator Actions Remote safe shutdown procedures will require that prior to main control room evacuation the reactor, the main steam isolation valves, and the reactor coolant pumps be tripped, thus establishing a hot standby condition. Closure of the pressurizer PORV 's block valves, placing the switches for the ASDVs to the closed position, placing the standby centrifugal charging pump in pull -to-lock, and opening the RWST outlet valves to the charging pump suction will be accomplished from the main control board after alarm confirmation (promptly) to prevent over cooling situations from either the primary or secondary side of the plant and ensuring proper RCS inventory control. Additionally, capabilities to trip the four MSIV 'S, the four RCP 's and the pressurizer PORV 's and atmospheric relief valves exist outside the main control room. After a confirmed fire alarm for a main control room or cable spreading room fire, a control room operator (CRO) and nuclear systems operator (NSO) are dispatched to the Train B switchgear and emergency diesel generator rooms to take actions as directed by procedure. In the time interval required for the operators to evacuate the main control room and man the RSS facilities, decay heat removal is accomplished automatically by the steam generator safety valves. No other function is required initially to maintain a decay heat sink for the reactor. Upon arrival at the RSS facilities, the operators will transfer control capability to the RSS facility by means of "Remote-Local" selector switches at the RSS locations and take the actions necessary to maintain control of the RCS inventory and pressure, and decay heat removal functions within the time frames described in sections 3.3.3.1 and 3.3.3.3. Control of the Train B Diesel Generator will be taken and if a Loss of Offsite Power (LOOP) occurs, clear and load EDE -SWG-6 to support safe shutdown. The operators will also trip the power supplies for engineered safety features actuation system (ESFAS) logic and cooling tower actuation logic to prevent inadvertent activation of these functions. The operators will then disable (trip power supply breakers) all equipment which is properly positioned in its safe shutdown position. Any additional recovery actions needed to maintain hot standby or to start a cooldown will be completed if inadvertent safeguard operation, tower actuation or "HOT SHORT " actuation occurs.

9) Remarks Separate tables are furnished for each of the safe shutdown functions. In several instances a safe shutdown function requires components from several systems to perform its safe shutdown function.

Appendix R Section III.L requires that only one train of equipment necessary to achieve and maintain hot standby must be available from alternate or dedicated RSS shutdown facilities. Redundancy is not required. Equipment required to achieve and maintain cold shutdown can be repaired within 72 hours. For Seabrook, the preferred RSS shutdown equipment is Train B. The

Train B RSS equipment with R/L selector and control switches have redundant control circuit fuses. This ensures that the local control circuit will still be operable in case the MCR control circuit blows the circuit fuse before control is transferred to local. For conservatism, redundant Train A equipment is typically listed in the RSS equipment lists in Appendix III, for example, both the Train A and the Train B charging pumps are listed whereas only one (Train B) is required to provide the safe shutdown function. This Train A equipment is desired, but not required, for safe shutdown. In some cases the Train A equipment is not listed just for conservative redundancy but is actually required for safe shutdown, for example, the SI accumulator isolation valves where there are two Train A and two Train B required valves. In order to simplify the tabulation, the following are not listed: manual valves in the process flow path; mechanical check valves which provide a Safe Shutdown system boundary; normally closed manual valves which provide a Safe Shutdown system boundary; mechanical relief valves; and root valves on small instrument lines. The review of these valves is documented by the marked P & I Diagrams. Tables are provided for the following functions which satisfy the performance goals stated in Appendix R, Paragraph III.L.2 SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 14 Section 3.3 Page 3.3-14 Function Table No. Decay Heat Removal 3.1.3.1 Reactor Coolant Inventory and Pressure Control 3.1.3.2 Reactivity Control 3.1.3.3 Process Monitoring 3.1.3.4 Safeguard Actuation System 3.1.3.5 Cold Shutdown 3.1.3.6 Service Water 3.1.3.7 Primary Component Cooling Water 3.1.3.8 (Deleted) 3.1.3.9 Control Building Air Handling 3.1.3.10 Diesel Generator Building Air Handling 3.1.3.11 Containment Enclosure Air Handling 3.1.3.12 Emergency Feedwater Pumphouse Air Handling 3.1.3.13 Primary Auxiliary Building Air Handling 3.1.3.14 Service Water Air Handling 3.1.3.15 (Deleted) 3.1.3.16 Electrical Distribution Emergency 3.1.3.17 Diesel Generators 3.1.3.18 Communication 3.1.3.19 3.3.9 Analysis and Evaluation of Fire Areas An evaluation is provided as to whether the Appendix R requirements or safe shutdown requirement are satisfied.

Under normal operation both outboard and both inboard dampers are open. If both outboard or both inboard dampers go closed, the Containment Enclosure Air Handling (EAH) system operates in recirculation mode. The normal and recirculation modes for EAH system operation both satisfy the safe shutdown function. If the outboard dampers and the inboard dampers operate independently such that either the supply or the exhaust path but not both are isolated, there could be an air flow problem in EAH system. Outboard dampers are powered from a single Train A power supply. Inboard dampers are powered from a single Train B power supply. The circuit design for the outboard and inboard dampers is such that a spurious signal in either or both circuits will cause both outboard and inboard dampers to operate together, either both open (normal mode) or both closed (recirculation mode). The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 9 Section 3.4 Page 3.4-1 3.4 ALTERNATIVE SAFE SHUTDOWN - EMERGENCY FEEDWATER PUMPHOUSE FIRE A fire in this area disables both emergency feedwater (EFW) pumps, associated EFW flow control valves, and related instrumentation. An immediate plant trip in response to this fire event is not desirable since this would place a demand on the EFW system which may not be available. Instead, plant operation will be maintained stable at 100% power conditions using the normal feedwater system while the fire event is assessed and appropriate mitigating actions are determined. The plant will not be perturbed by any action, including a power change, that might result in a plant trip and demand on the EFW system. If it is determined that plant shutdown is warranted, th en normal procedures will be used eliminating an EFW system demand. This approach is consistent with the Technical Specification 3/4.7.1.2 Bases. Plant shutdown using normal procedures does not require use of the EFW system so the time critical operator action response times related to the EFW system do not apply (see Section 3.2.2.3) for this fire area. If an immediate plant shutdown was required, then the startup feedwater pump (SUFP) would be used to provide the EFW function. Since both EFW trains are disabled by a fire in this area, this is considered an alternate shutdown capability area. Safe shutdown would be controlled from the main control room. Since this is not the preferred response, immediate plant shutdown is considered a beyond design basis condition analyzed for defense in depth. If the EFW flow control valves are disabled, then the EFW pumps may have to be tripped to control excessive EFW flow. The SUFP and its valves can provide throttled flow to prevent overfill/over cooling conditions. Since this is a beyond design basis, defense in depth, response, the time critical operator action response times related to the EFW system do not apply for this fire area. The following analysis evaluates the beyond design bases response of shutdown controlled from the main control room with an immediate plant trip using the SUFP to provide the EFW function. Plant shutdown using normal procedures does not require use of equipment in this fire area so no further analysis of normal shutdown is required. 3.4.1 Main Control Room Safe Shutdown Safe shutdown will be accomplished with control from the main control room, utilizing the safe shutdown equipment in the following locations:

a. Non-Essential Switchgear Area

b. Condensate Storage Tank Valve Room (CST)

c. Train A Switchgear Room

d. Train B Switchgear Room

e. Turbine Building SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 9 Section 3.4 Page 3.4-2 Actions required in the additional areas would be to realign the suction of the startup feedpump; realign the power supply of the startup feedpump from Bus ED

-SWG-4 to Bus EDE -SWG-5 (if offsite power is not available and not already aligned to Bus EDE-SWG-5); bypass the startup feedpump low suction pressure trip (prior to commencing cooldown) and trip the power supply breakers for the feedwater flow control valves. Safe shutdown will then be performed from the main control room. 3.4.2 Safe Shutdown Equipment List Tables that list all equipment, including instrumentation and vital support systems equipment, required to achieve hot standby and cold shutdown are provided in Appendix III.

Analysis With the exception of the systems/equipment discussed below, a fire in this area will only affect the Train B safe shutdown equipment and cables. The redundant Train A safe shutdown equipment and cables are located in other fire areas. Additional details on the fire protection measures and physical separation for this fire area are contained in Tabulation 3.2.7.48. Redundant emergency feedwater flow control valves and associated flow transmitters which are part of the alternative shutdown capability are located in the fire area. These valves are normally open valves and remain open for the initial phases of safe shutdown. Only two steam generators are required to satisfy the safe shutdown requirements: hence, only two valves on each of two lines need to be disabled (e.g., FW -FV-4214A, FW-FV-4214B, FW -FV-4224A and FW -FV-4224B). The operators will prevent additional spurious operations by tripping the power supply breakers for these valves in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). C. Evaluation A deviation from the Appendix R, Paragraph III.L.3 requirements exists in the emergency feedwater pump building. This deviation is justified based on the analysis and our assertion that additional modifications would not enhance fire protection safety.

9) Remarks 3.5.3 Review and Analysis A review of each of the lines listed in subsection 3.5.1 is provided to identify lines which could open and cause a LOCA.

The flow through each high -low interface path will be evaluated. If the flow is less then the capacity of one charging pump, then the open path is not considered a LOCA and no further circuit analysis is required. The effect of the flow on system operation would still need to be evaluated. If the flow exceeds the capacity of one charging pump, then further circuit analysis is required per the criteria in Section 3.1.8 to demonstrate that spurious valve operation can not result in an open path. A specific flow value may not be documented for cases where it is obviously unacceptable (ex. RHR/RCS isolation valves). Alternatively, a circuit analysis per the criteria in Section 3.1.8 can be used to demonstrate that spurious valve operation cannot result in an open high -low interface path so no flow analysis is needed. 3.5.3.1 Chemical and Volume Control System

a. Excess letdown line The high-low pressure interface is downstream of control valve CS

-HCV-123. This is a normally closed, fail close diaphragm valve. Upstream of CS -HCV-123 are two normally closed, fail close diaphragm valves, CS -V175 and CS -V176. Spurious opening of one valve will not open the path and prevent safe shutdown. The operators will prevent further spurious openings by tripping the 125 Volt dc power supply breaker for valves CS -V175 and CS -V176 in the Train B switchgear room. An additional disabling capability exists at the disabling panel for CS -V-175 in the Train B diesel generator room (Fire Area: DG -F-2B-A) should the primary capability be inaccessible due to a fire in the switchgear room.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 9 Section 3.5 Page 3.5-3 b. Normal letdown line The high-low pressure interface is downstream of parallel valves CS -HCV-189 and CS-HCV-190 (letdown flow control valves). These valves are motor operated drag valves. Upstream of CS -HCV-189 and CS -HCV-190 are fail close diaphragm valves CS -V145, RC-LCV-459, and RC-LCV-460. CS-HCV-189 or 190 failing full open results in a maximum flow rate that exceeds the charging pump capability . To isolate this path, the operator will close CS -V-145, RC-LCV-459 or RC-LCV-460. RC-LCV-459 and RC -LCV-460 can also be closed by tripping a circuit breaker at the 125 Volt distribution panels in the A Train switchgear room (Fire Area: CB -F-1A-A). An additional disabling capability exists in the Train A diesel generator room (Fire Area: DG -F-2A-A) for RC-LCV-459. c. Reactor coolant pumps seal bleedoff lines The high-low pressure interface is downstream of valves CS -V44 (Loop 3), CS -V59 (Loop 4), CS -V10 (Loop 1), CS -V28 (Loop 2). These valves are fail open diaphragm valves. However, these valves are not used for pressure reduction. The RCP seals are the pressure reduction device. If the bleedoff line is isolated downstream of the high/low interface, the pressure would equalize across the seals and pressurize the bleed lines. The low pressure portion of the bleedoff line is protected with relief valves CS -V173, CS-V794, and CS -V250. Bleedoff from the RCP seals will equal a maximum of 12 GPM either discharging to the reactor drain tank (RDT) if containment isolation valves CS -V168 or CS-V167 (normally open motor operated valves) close or to the charging pump suction. RCS fluid to the RDT is not recoverable but will be made up by flow to the charging suction from BAT or RWST. 3.5.3.2 Residual Heat Removal System The high-low pressure interface is downstream of motor operated valves (MOV) RV -V23 (Loop 1) and RC-V88 (Loop 4). Upstream of each MOV is MOV RC -V22 and RC -V87. All four valves are normally closed when the RCS is above RHR design pressure of 600 psig and interlocked to prevent opening when RCS pressure is above 365 psig. During normal operation these normally closed MOV 's will also be deenergized at their respective motor control center, thus there is no possibility of a short circuit, or hot short circuit opening the valves. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 9 Section 3.5 Page 3.5-4 3.5.3.3 Pressurizer Power Operated Relief Valves The high-low pressure interface is downstream of paralleled valves RC -PCV-456A and RCV-PCV-456B. These valves are normally closed, fail closed solenoid operated valves. Upstream of each of these valves are the PORV block valves RC-V122 and RC -V124. These MOV's are normally open. Since the PORV block valves are normally open MOVs and will be closed for all fires which could cause spurious PORV operation, a hot short to the control logic or power to the PORV or block valves will not cause PORV blowdown. The operators will prevent the opening of the solenoid operated valves RC -PCV-456A and RC-PCV-456B by tripping their respective power supply breakers in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). An additional disabling capability exists in the Train A and Train B diesel generator rooms (Fire Areas: DG -F-2A-A and DG-F-2B-A) respectively should the primary capability be inaccessible due to a fire in the switchgear room. 3.5.3.4 Reactor Vessel Head Vent The high-low pressure interface is downstream of valve, RC -V323. This is a normally closed MOV. Upstream of RC -V323 is a normally closed, solenoid valve, RC -FV-2881. Spurious opening of one valve will not open the path. The operators will prevent further spurious openings by disabling the normally closed MOV RC -V323 and solenoid RC -FV-2881 at the motor control center and 125 volt dc distribution panel, respectively, in the B Train switchgear room (Fire Area: CB-F-1B-A). An additional disabling capability exists for RC-FV-2881 in the Train B diesel generator room (Fire Area: DG -F-2B-A) should the primary capability be inaccessible due to a fire in the switchgear room.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 9 Section 3.6 Page 3.6-1 3.6 ASSOCIATED CIRCUITS 3.6.1 Definition of Associated Circuits of Concern Circuits other than those directly required for the safe shutdown functions which have the potential to affect or prevent post -fire safe shutdown are considered associated circuits of concern. Associated circuits of concern are defined as those cables (Class 1E and non -Class 1E) that: a. Have a physical separation less than that required by Section III.G.2 of Appendix R, and b. Have one of the following:

1) a common power source with the safe shutdown equipment (redundant or alternative) and the power source is not electrically protected from the circuit of concern by coordinated breakers, fuses or similar devices, or

2) a connection to circuits of equipment whose spurious operation would adversely affect the safe shutdown capability (e.g., RHR/RCS isolation valves, PORVS, steam atmospheric dump valves, etc.), or

3) a common enclosure (e.g., panel) with the shutdown cables (redundant or alternative) and a) are not electrically protected by circuit breakers, fuses or similar devices, or b) will allow propagation of fire into the common enclosure.

3.6.2 Discussion of Methodology Sections 3.6.2.1, 3.6.2.2 and 3.6.2.3 in conjunction with Figure 3.6-1 describes the methodology utilized to address the following types of associated circuits:

a. Common power source

b. Spurious operation

c. Common enclosure

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 9 Section 3.6 Page 3.6-2 3.6.2.1 Common Power Source As stated in FSAR Section 8.3.1.4, all non -Class 1E circuits are associated relative to electrical separation with either Train A or Train B in accordance with the provisions of FSAR Appendix 8A Section 4.5a. Based on these design consideration s, associated circuits can be powered from the Class 1E electrical distribution emergency (EDE) system or from the

non-Class 1E electrical distribution (ED) system and further may be routed in the same raceways and terminate in the same enclosure as Class 1E circuits. Although all safe shutdown circuits are powered from the EDE system, not all safe shutdown circuits are considered to be Class 1E. There are no Safe shutdown circuits, which require electrical power to operate, powered from the ED system. Associated circuits that are powered from the EDE system, and are associated with the safe shutdown circuits by a common power supply, are protected by a coordinated circuit breaker and; hence, are not considered to be associated circuits of concern. The above design considerations eliminates as associated circuits of concern all circuits which have no deleterious impact on safe shutdown. 3.6.2.2 Spurious Operation The review of each system required to satisfy the safe shutdown functions included all valves necessary to operate the system or maintain the system process boundaries. This assures that the safe shutdown system will operate as designed. If valves or other equipment from one train (i.e., Train A) are required for operation or could prevent operation of the other train (i.e., Train B), then additional reviews are performed to determine the failure modes and provide manual actions or operations of other equipment that would prevent the spurious operation from affecting safe shutdown. An example of this is the primary component cooling water containment isolation function which requires that both Train A and Train B valves remain open. The inboard containment isolation valve is the same train as the pumps which supply primary component cooling water while the outboard valve is of the opposite train but could be operated manually upon loss of power or damage to electrical circuit. To prevent the spurious operation of various safety injection system valves, containment isolation valves and service water valves, the engineered safety features actuation system logic and the tower actuation logic are disabled by tripping their power supplies after a control room evacuation. In several instances (e.g., RHR/RCS isolation valves), the power supplies are permanently disabled (breaker tripped and locked out) to prevent spurious operation. The spurious operation of valves protecting high -low pressure interfaces is discussed in Section 3.5. See Section 3.1.8 for criteria to evaluate components for spurious operation . SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 9 Section 3.6 Page 3.6-3 3.6.2.3 Common Enclosures The deleterious effects of fire on associated circuits in common enclosures is eliminated by the following three design considerations:

a. Coordinated circuit breakers, fuses or similar devices will assure that the associated circuit failure does not prevent the redundant train from performing its safe shutdown function. b. The cables are qualified to IEEE Standard 383; hence, the propagation of the fire from one train to the redundant train in another fire area/zone is very unlikely.

c. Train and channel separation for cable routing is assured by a computerized cable routing program which does not allow cables with different circuit code assignments to be routed in the same raceways.

Based on the above design considerations, associated circuits in common enclosures are not considered associated circuits of concern.

Appendix R P & I Diagrams (Typical) Rev 5 Appendix I Page I-1 P & I DIAGRAMS (TYPICAL) This section originally contained photographs of the marked P & I Diagrams for the decay heat removal safe shutdown function. These drawings were typical of the P & I Diagrams which were marked for each safe shutdown function and not all inclusive, thus they have been removed from this appendicies. The typical diagrams included in this section were only to show the methodology used for the original report preparation and were not in tended to be updated for report revisions. The latest design documents, not these typical drawings, should be used to evaluate the Safe Shutdown Capability. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50. Appendix R Schematic Diagrams & Cable Schematics (Typical) Rev 5 Appendix II Page II-1 Schematic Diagrams & Cable Schematics (Typical) This section originally contained drawings that were typical of those which were marked for each safe shutdown function. The typical drawings in cluded in this section were only to show the methodology used for the original report preparation. These typical drawings were not intended to be updated for report revision. The original drawings were provided to show marked-up electrical schematic diagrams, cable schematics, and cable tables for the Train A decay heat removal safe shutdown function. The drawings were marked by shading and by cross-hatching. The equipment and cables which were shaded were isolated by a "Local Remote" selector switch or other isolation device and were not considered for further review. The equipment and cables which have been cross-hatched were analyzed, and it was determined that there was no effect on safe shutdown capability. These equipment and cables were not considered for further review. The latest design documents, not these typical drawings, should be used to evaluate the Safe Shutdown Capability.

The equipment is mechanical with no electrical requirement.

2. During normal operation, the valve is in its safe shutdown position.

To prevent spurious operations, this equipment will be disabled at the appropriate control location.

3. Disabling the valve at the appropriate control location will reposition it for shut shutdown.

4. Air is not needed to position or to reposition the valve for safe shutdown.

5. This valve is permanently disabled by tripping its circuit breaker at the MCC.

6. During normal operation, the valve is in its hot shutdown position.

To prevent spurious operations, this equipment will be disabled at the appropriate control location. For cold shutdown, the valve will be energized for repositioning.

7. These valves are closed with their circuit breakers locked open during 100% power operation.

This will prevent spurious operation. For cold shutdown, these valves are energized for repositioning.

8. These valves are also listed in Table MCR 3.1.3.6.

9. Electrical group conduit drawing, 9763

Equipment is mechanical with no electrical requirement.

2. CS-V-423, 410, 416, 431, 437, 439, 442 are non

-electrically operated valves and will be manually positioned as required to provide their reactivity control function during safe shutdown.

3. Electrical conduit plan drawing, 310766, listed only to show fire zone correlation reference to Primary Auxiliary Building area covered by piping Drawings 805216, 805229, 805230, where Valves CS-V-410, 416, 423, 431, 437, 439, 442 are identified in plan and section.

4. This equipment is listed because it can spuriously start due to cable failure in the boration & dilution flow control valve control circuits. Spurious pump start by itself from failure of its cables is not of concern since CS-FCV-111A remains closed.

.Notes  1. The equipment is mechanical with no electrical requirement. 

2. During normal operation, this equipment is in its safe shutdown position (locked closed). To prevent spurious operation, its circuit breaker is administratively controlled locked open (off).

3. Disabling the valve at the appropriate control location will reposition it for safe shutdown.

4. Air is not needed to position or to reposition the valve for safe shutdown.

5. The review of this valve was conducted with the assumption that it will be closed from the Control Room prior to evacuation and that a fire will not reset its logic before the operator could man the remote shutdown station and throw the "Remote-Local" switches to "Local". Its cables and supporting controls were listed to analyze the possibility of the valve reopening after the isolation switch has been positioned to "Local". 6. Circuit breaker tripped to disable the redundant controls.

.Notes  1. Equipment is mechanical with no electrical requirement.

2. CS-V-423, 410, 416, 431, 437, 439, 442 are non

-electrically operated valves and will be manually positioned as required to provide their reactivity control function during safe shutdown.

3. Electrical conduit plan drawing, 310766, listed only to show fire zone correlation reference to Primary Auxiliary Building area covered by piping Drawings 805216, 805229, 805230, where Valves CS

-V-410, 416, 423, 431, 437, 439, 442 are identified in plan and section.

4. This equipment is listed because it can spuriously start due to cable failure in the boration and dilution flow control valve control circuits. Spurious pump start by itself from failure of its cable is not of concern since CS

-FCV-111A remains closed so the pump cables are not listed.

5. Disabling the valves at the appropriate control location will reposition CS

-FCV-110B and C S-FCV-111B for safe shutdown. Air is not needed to position or to reposition the valve for safe shutdown.

.Notes  1. Equipment is mechanical with no electrical requirements. 

2. Electrical conduit Plan Drawing 310443, listed only to show fire zone correlation reference to control building area covered by HVAC Drawing 604094 where CBA Dampers 24 D, E, and F are identified in plan.

3. Process connections showing positioning of air operated dampers, DP-24A-F, by pneumatic temperature indicating controllers, CBA-TIC-5571 and 5572, are detailed on I&C Loop Diagrams 510159 and 510160.

4. Instrument air is required for normal positioning of dampers for area temperature control. Should IA fail, dampers 24A, 24B, 24E and 24F will fail "as is" and 24C and 24D fail open. The operators can start and stop fans to maintain switchgear room habitability.

5. Dampers fail open on loss of instrument air, which is the safe shutdown position.

Rev. 5 Appendix IV Page IV-1 Raceway Arrangement Drawings (Typical) This section originally contained photographs of marked raceway arrangement drawings for several fire areas/zones of the plant containing redundant Safe Shutdown equipment and cables. The typical drawings included in this section were provided to only show the methodology used for the original report preparation. These typica l drawings were not intended to be updated for report revisions. These original drawings were typical of the raceway arrangement drawings which were marked for each fire area/zone containing safe shutdown equipment and cables. The latest design documents, not these typical dr awings, should be used to evaluate the Safe Shutdown Capability.

SEABROOK STATION Fire Protection of Safe Shutdown Capability (10CFR50, Appendix R) Revision 1 4 SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Introduction Rev. 5Section 1 Page 1-1 INTRODUCTION General Design Criterion 3, "Fire Protection," of Appendix A, "General Design Criteria for Nuclear Power Plants," to 10 CF R Part 50" Licensing of Producti on and Utilizatio n Facilities" requires that structures, systems and components important to safety shall be designed and located to minimize, consistent with other safety requirements, the probability and effects of fires. Appendix R, "Fire Protection Program for Nuclear Power Facilities Opera ting Prior to January 1, 1979" to 10 CFR Part 50 was issued on Novemb er 19, 1980 (45 FR 76602). Paragraph III.G, "Fire Protection of Safe Shutdow n Capability," requires that fire damage be limited so that: a. One train of systems necessary to achieve and maintain hot shutdown conditions from either the control room or emergenc y control station(s) is free of fire damage; and b. Systems necessary to achieve and maintain cold shutdown from either the control room or emergency control station(s) can be repaired within 72 hours. This requires each licensee to assess those areas of the plant"....where cables or equipment, including associated non-safety circuits that could prevent operation or cause maloperation due to hot shorts, open circuits, or shorts to ground of redundant trains of systems necessary to achieve and maintain hot shutdown conditions are located in the same fire area..." The regulation establishes separation requirements for areas outside of primary containment and inside noninerted containment. Appendix R, paragraph III.L, "Alternative and Dedicated Shutdown Capability," establishes the following performance goals for the shutdown functions: a. The reactivity control function shall be capable of achieving and maintaining cold shutdown reactivity conditions. b. The reactor coolant makeup function shall be capable of maintaining the reactor coolant level within level i ndication in the pressurizer. c. The reactor heat removal function shall be capable of achieving and maintaining decay heat removal. d. The process monitoring function shall be capable of providing di rect readings of the process variables necessary to perform and control the above functions. e. The supporting functions shall be cap able of providing process cooling, lubrication, etc., necessary to permit operation of the equipment used for Safe Shutdown functions. Branch Technical Position CMEB 9.5-1 "Guidelines for Fire Protection for Nuclear Power Plants," Rev. 2, July 1981 reiterates the above requirements in Section C.5.b and C.5.c. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Introduction Rev. 5Section 1 Page 1-2 By letters dated March 16, 1981 (from R.L. Tedesco to W.C. Tallman) and September 30, 1981 (from D.G. Eisenhut to W.C. Tallman) the Nuclear Regulatory Commission (NRC) transmitted "Request for Additional Information, Seabrook Station, Units 1 & 2, Fire Protection Program, Power System." This document requested New Hampshire Yankee (NHY) to provide information relative to the equipment and cabling required to achieve and maintain hot and/or cold shutdown. By letter dated July 27, 1982 (from F.J. Miraglia to W.C. Tallman) the NRC transmitted Auxiliary System Branch RAI's.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Report Preparation Rev. 13 Section 2 Page 2-1 REPORT PREPARATION/MAINTENANCE To establish a methodical course of action and provide guidance to the various organizations required to support the initial development of the Safe Shutdown Capability program, UE&C procedure TP -2 (NHY Procedure 38160) titled "Procedure for Review and Report Preparation for 10 CFR Part 50 Appendix R, Fire Protection of Safe Shutdown Capability " was prepared. The salient points of this procedure are as described in Sections 2.1 to 2.8. As modifications are implemented to the plant, the effect of these modifications to this report must be evaluated. The evaluation process is as described in Section 2.9. 2.1 DETERMINATION OF FIRE AREAS/ZONES The fire areas/zones are as delineated in "Fire Protection Program Evaluation and Comparison to Branch Technical Position APCSB 9.5 -1, Appendix A " or as determined by the Responsible Engineer. 2.2 DETERMINATION OF SAFE SHUTDOWN SYSTEMS The Safe Shutdown systems were determined by considering the minimum performance goals established in Appendix R, Paragraph III.L.2, and utilizing the following sources for guidance: 2.2.1 Final Safety Analysis Report - Seabrook Station 2.2.2 Fire Protection Program Evaluation and Comparison to Branch Technical Position APCSB 9.5 -1, Appendix A 2.2.3 Station Operating Procedure No. OS1200.01 "Safe Shutdown and Cooldown from the Main Control Room " 2.2.4 Station Operating Procedure No. OS1200.02 "Safe Shutdown and Cooldown from the Remote Safe Shutdown Facilities " 2.2.5 United Engineers & Constructors Inc. Engineering 2.2.6 Yankee Atomic Electric Co. Engineering 2.2.7 New Hampshire Yankee Engineering

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Report Preparation Rev. 13 Section 2 Page 2-2 2.3 DETERMINATION OF SAFE SHUTDOWN EQUIPMENT The minimum equipment necessary to perform the Safe Shutdown function was determined by utilizing the following sources: 2.3.1 Final Safety Analysis Report - Seabrook Station 2.3.2 Fire Protection Program Evaluation and Comparison to Branch Technical Position APCSB 9.5 -1, Appendix A 2.3.3 Station Operating Procedure No. OS1200.01 "Safe Shutdown and Cooldown from the Main Control Room " 2.3.4 Station Operating Procedure No. OS1200.02 "Safe Shutdown from the Remote Safe Shutdown Facilities " 2.3.5 Piping and Instrumentation (P&I) Diagrams 2.3.6 United Engineers & Constructors Inc. Engineering 2.3.7 Yankee Atomic Electric Co. Engineering 2.3.8 New Hampshire Yankee Engineering Sets of P&I Diagrams and One -Line Diagrams were marked to indicate hot standby equipment and cold shutdown equipment for main control room shutdown and remote safe shutdown. Train A equipment was marked in red, and Train B equipment was marked in green. Photographs of typical marked P&I Diagrams are contained in Appendix Section I. 2.4 DETERMINATION OF SAFE SHUTDOWN CABLES Considering the equipment defined and utilizing their related electrical schematic diagrams and cable schematics, the cables required for Safe Shutdown were determined. The raceways through which these cables were routed were determined; and then their associated fire area/zone(s) were determined. To document the review, the "10 CFR 50 - Appendix R, Safe Shutdown Equipment List" was prepared from data gathered in this review. Copies of typical schematic diagrams and cable schematics are contained in Appendix Section II. Copies of the safe shutdown equipment lists are contained in Appendix Section III.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Report Preparation Rev. 13 Section 2 Page 2-3 The equipment required for fire safe shutdown can be divided into supporting equipment and supported equipment. For example, CC -TE-2197 is supporting equipment for CC pump trip and CC-P-11A/C are the corresponding supported equipment. Supported equipment tag numbers are typically listed in the Appendix III Equipment Tables - "Equipment Id No. " column and represent the major components used to perform each safe shutdown function. Supporting equipment tag numbers are typically not listed in the "Equipment Id No. " column but should be listed in the "Supporting Control and Instrumentation Equipment " columns. The following guidance should be used for lisiting supported and supporting equipment tag numbers in the Appendix R Report Section 3 Tabulations and for assigning the descriptions for CASP cables. The tag number for supporting equipment should be listed in the tabulation for the fire zone/area in which the equipment is located with an "X" in the equipment column and an "X" in the cable column. For other fire zones/areas which contain just the cable for the supporting equipment, the cable should be accounted for with an "X" in the cable column using the tag number of the supported equipment. The safe shutdown analysis for each fire zone/area should discuss the impact of fire damage to the supporting equipment cables and equipment in terms of the impact on operation of the supported equipment. The cable "description " in CASP for supporting equipment cables should be the support ed equipment tag number. Note that this specific guidance was added to the Report in 2013 to address future Report changes but was typically applied in the past. 2.5 COMPUTER INPUT AND REPORTS The following data were input to UE&C 's "NRC Emergency Shutdown Program NRCESP " Program No. EL -130: a.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Report Preparation Rev. 13 Section 2 Page 2-4 2.6 DETERMINATION OF SAFE SHUTDOWN RACEWAYS Utilizing the "Safe Shutdown Raceways and Associated Cables by Fire Zone " computer report, a set of raceway arrangement drawings was marked as follows: 2.6.1 Train A raceways, boxes, and termination equipment were marked in red. 2.6.2 Train B raceways, boxes, and terminating equipment were marked in green. 2.6.3 Equipment which is manually operated or disabled was marked in orange. A "D" was placed beside equipment to be disabled. An "M" was placed beside equipment needed to be manually operated. 2.6.4 Rated fire walls and barriers were marked in black. Photographs of typical marked raceway arrangement drawings are contained in Appendix Section IV. 2.7 ANALYSIS OF RACEWAYS AND EQUIPMENT TO SATISFY APPENDIX R REQUIREMENTS 2.7.1 Each fire area/zone that contained Safe Shutdown equipment or cables was reviewed to determine if Appendix R, Paragraph III.G.2 separation requirements were satisfied. 2.7.2 If the Appendix R requirements were not satisfied, further analysis was performed to determine the effects of a hot short circuit, short circuit, open circuit, ground or other equipment failure. 2.7.3 If the Safe Shutdown function was affected by a hot short circuit, short circuit, open circuit, ground or other equipment failure, then the following analysis to satisfy the Appendix R requirements was provided: 2.7.3.1 Analysis which documented that the in situ and transient combustibles were insufficient to cause a fire which affected the redundant trains of equipment and cables. 2.7.3.2 A three-hour fire barrier or a one-hour barrier and sprinklers between the redundant equipment or cables. 2.7.3.3 Rerouted the redundant cable out of the fire area/zones, or provided twenty feet of separation and sprinklers in the area.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Report Preparation Rev. 13 Section 2 Page 2-5 2.7.3.4 Provided an alternative or dedicated safe shutdown equipment or system (See Section 3.3 and 3.4). 2.7.3.5 Requested a deviation from the 10 CFR 50, Appendix R requirements based on the combustibles in the fire area/zone, the spatial separation and the protective measures provided.

(See Section 3.7). 2.8 HIGH-LOW PRESSURE INTERFACES A list was prepared of the high

-low pressure interfaces and the lines with two or more electrically operated valves which could open and potentially cause a LOCA. A review was performed in the same manner as discussed in Section 2.4 and 2.5 utilizing this list. An analysis and evaluation were then performed.

(See Section 3.5) 2.9 MODIFICATION EVALUATION As plant modifications are implemented, their effect on the analysis contained in this report must be evaluated to ensure that the safe shutdown capability in the event of a fire is maintained. This evaluation will consider the UFSAR, this Appendix R Report, Supporting Documentation and the latest issue of design documents. If necessary, appropriate markups of documents will be included in the design change package to reflect any change in the Appendix R safe shutdown analysis.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 10 Section 3.1 Page 3.1-1 SAFE SHUTDOWN CAPABILITY 3.1 DISCUSSION OF BASES AND POSITIONS 3.1.1 General 10 CFR Part 50 Appendix R, Paragraph III.G.1 requires that fire damage be limited so that:

a. One train of systems necessary to achieve and maintain hot standby condition from either the control room or emergency control station(s) is free of fire damage; and

b. Systems necessary to achieve and maintain cold shutdown from either the control room or emergency control station(s) can be repaired within 72 hours. Based on requiremen t "a" above, the design basis of Seabrook Station is that one train of systems necessary to achieve and maintain hot standby from the control room or the emergency control stations (hereafter designated the remote safe shutdown facilities) is free of fire damage. Under this basis, Appendix R, Paragraph III.G.2 and III.G.3 will apply to the safe shutdown paths controlled from the main control room or the remote safe shutdown facilities. Any deviations from the III.G.2 and III.G.3 criteria will be with respect to the main control room or the remote safe shutdown facilities and is addressed in Sections 3.2.7, 3.3.9, 3.4.3 and in the List of Deviations Section 3.7 of this report. For fires in some areas of plant, alternative shutdown capabilities are provided as discussed in Sections 3.3 and 3.4.

This Section defines the bases and positions utilized in determining and reviewing the shutdown capabilities that will satisfy the requirements of Paragraph III.G. These capabilities can be utilized to safely shut down the reactor in the event of a fire in any area/zone of the plant. 3.1.2 Safe Shutdown "Safe Shutdown " for purposes of the review is defined as a capability to bring the reactor from a 100 percent power operating condition to a "cold shutdown " condition. Included in this are conditions "hot standby, " "hot shutdown, " "cold shutdown, " and maintenance of "cold shutdown. " SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 10 Section 3.1 Page 3.1-2 The design basis event for safe shutdown is a postulated fire in a specific fire area/zone with or without the loss of offsite power (LOOP). This design basis was used for the original Appendix R Report preparation. The LOOP was assumed to occur whether the specific fire being analyzed caused it or not. The diesel generators (DGs) were analyzed to both automatically start and load, and not automatically start and load. An engineering evaluation prepared in 2007, documented that this was a conservative design basis since Appendix R does not require an arbitrary LOOP for non-alternate shutdown fire areas/zones (i.e., for shutdown control from the main control room). For future safe shutdown analyses, offsite power can be credited to remain available for

non-alternate shutdown fire areas/zones if the cables required to support offsite power are not damaged by the fire (i.e., an arbitrary LOOP need not be assumed). This approach provides greater analysis flexibility. No other design basis event (e.g. seismic or LOCA) is considered to occur coincident with the fire event. The safe shutdown functions shall assure the following:

a. No fuel clad damage. b. No rupture of any primary coolant boundary.

c. No rupture of containment boundary.

d. Reactor coolant system process variables shall be within those predicted for a loss of normal AC power.

e. Achievement of cold shutdown conditions within 72 hours and maintenance of cold shutdown conditions thereafter.

3.1.3 Redundancy

To assure a safe shutdown capability pre -fire, two redundant trains (Train A and Train B) of equipment are provided for each safe shutdown function. Each train contains a complete complement of the equipment, cabling, instrumentation and controls necessary to perform the safe shutdown functions. In several instances a single mechanical equipment is common to both trains (i.e., condensate storage tank, mechanical manual valves, piping, HVAC ducts, etc.). Single failure is not assumed to occur except to equipment that is damaged by the fire.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 10 Section 3.1 Page 3.1-3 3.1.4 Determination of Safe Shutdown Functions The safe shutdown functions are determined by considering the performance goals established in Appendix R, Paragraph III.L.2. The systems or portions of systems necessary to satisfy safe shutdown are subsequently determined. 3.1.5 Determination of Safe Shutdown Equipment Safe shutdown systems are the systems required to achieve the performance goals listed in Section 1. The equipment for these systems can be divided by function as Hot Standby (Reactor tripped and T -Avg above 350F) and Cold Shutdown (Reactor tripped/and cool down of the Reactor Coolant System T -Avg equal to or below 200F). The following criteria are used to determine the equipment required for safe shutdown:

a. The equipment is required to operate to permit a safe shutdown system to perform its safe shutdown function.

b. The equipment

's maloperation can prevent a safe shutdown system from performing the safe shutdown function.

c. The equipment is a process or electrical boundary for a safe shutdown system.

3.1.6 Safe Shutdown System Boundaries The safe shutdown system process boundaries are established by the following devices:

a. Normally closed manual valve

b. Check valve

c. Electrically operated safe shutdown valve

d. Root valve on small instrument lines to non

-safe shutdown instruments

e. Relief valve

f. Redundant valves on high

-low pressure boundaries

g. Boundary valve between a safe shutdown process line and a non

-Safe Shutdown process line which if it is an incorrect position will not affect the operation of the Safe Shutdown system.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 10 Section 3.1 Page 3.1-4 The safe shutdown electrical system boundaries are established by the following devices:

h. Isolation device (i.e., coordinated circuit breaker, fuse, transducer, etc.)

i. "Remote Local

" selector switch Cables isolated by "Remote-Local" selector switches or other isolation devices are not included in the review. 3.1.7 Manual Operator Actions Manual operator actions must satisfy the following considerations:

a. Sufficient manpower and time is available to perform all required manual actions.

b. There is accessibility to the equipment to perform the manual action either during or after the fire.

3.1.8 Spurious Operation The evaluation of the effects of spurious equipment operation on safe shutdown functions considers the effects of hot short circuits, short circuits, open circuits and grounds. The effects of hot short circuits are considered on the following:

a. Energized 120V ac grounded circuits

b. De-energized 120V ac grounded circuits

c. Energized 120V ac ungrounded circuits

d. Energized 125V dc ungrounded circuits Hot short circuits are not considered for disabled (tripped power supply) 3

-phase 480 Volt ac circuits, ungrounded 1 -phase 120 Volt ac circuits and ungrounded 125 Volt dc circuits as these would require multiple hot shorts in the correct sequence to cause a device to function. These are considered incredible events. The effects of short circuits, open circuits and grounds are considered for all circuits evaluated for spurious operation.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 10 Section 3.1 Page 3.1-5 The above discussion does not provide all of the criteria used for evaluating spurious component operations during the original Appendix R Report preparation. An engineering evaluation prepared in 2007 reviewed various Seabrook, NRC, and industry documents to re -create the circuit analysis methodology bases used for the fire safe shutdown analyses that was not included in the above discussion. The following documents the added methodology criteria. The analyses shall consider fire induced damage to any and all unprotected cables in the fire area/zone being analyzed. Each cable failure shall be considered individually, one -at-a-time, and the effects of any spurious operation(s) evaluated. If the effect is unacceptable (ex. loss of inventory), then operator actions, or other corrective actions (see Section 2.7), are specified to mitigate the effects of the spurious operation. If the effect is acceptable, then additional sequential cable failures and resultant spurious operations of same function components must also be considered (ex. spurious opening of other normally closed series valves in a potential diversion flow path). If their effects are unacceptable, then appropriate preventative/disabling operator actions (ex. open a circuit breaker) are specified to prevent the unacceptable condition. Mitigating and preventative/disabling actions that rely on electrical power, ex. MOV operation, can not credit components with unprotected cables in the fire area/zone being analyzed. The basis described in the previous paragraph is typically referred to in the industry as any-and-all, one-at-a-time. In addition, it will be assumed that the loss of function from fire damage to unprotected cables within a fire area cable will prevent the effected components from operating to support safe shutdown but any resulting state changes will be evaluated as spurious operations following the above criteria of one -at-a-time. Also, a protective device state change from a short circuit (open a fuse or trip a circuit breaker) will be considered a spurious operation and will be evaluated following the above criteria of one -at-a-time including any end component state changes, ex., loss of control power to a normally energized solenoid operated valve (SOV) would cause the SOV to change state as a spurious operation. For Seabrook, failure of an individual cable typically only causes spurious operation of one component although there are exceptions where one cable failure can cause spurious operation of multiple components.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 10 Section 3.1 Page 3.1-6 The complete circuit for each equipment tag typically consists of multiple cables routed through many fire zones. It is expected that applying the failure modes to some cables in a circuit may not actually result in a spurious operation of the corresponding equipment. However, it appears that the original safe shutdown analyses conservatively assumed that every cable failure would cause spurious operation of the supported component(s) since there was no evidence found in the original analyses of credit being taken for analyzing specific conductor interactions as the basis for concluding that there was no resulting spurious operation. For future safe shutdown analyses, it is acceptable to use circuit analysis to demonstrate that a fire -induced cable failure can not cause a spurious operation. These circuit analyses should be included in appropriate engineering documents. Operator actions to mitigate spurious component operation must meet the criteria provided in Section 3.1.7 on manpower, timing and accessibility considering the system effect of the corresponding spurious operation. Preventative/disabling operator actions should be documented in a procedure and be able to be completed in a reasonable time consistent with completion of time critical mitigating actions. Automatic signals can be credited if their circuits are included in the analysis to ensure that their cables are free of fire damage for the fire areas which credit the signals. Automatic signals with unprotected cables in a fire zone must be analyzed to fail to operate or spuriously operate because of fire-induced cable damage. The automatic signals must also be analyzed to operate as designed if the system conditions caused by the fire (ex. low level, high flow, loss of power, etc.) would initiate the automatic function to ensure that the automatic actuation is not detrimental to safe shutdown. The review assumes that all conductors within multi -conductor cables would short, open or ground due to a fire. Cable to cable interactions are not considered credible events because of the

thermoset cable insulation used at Seabrook Station. 3.1.9 Disabled (tripped power supply) Equipment To prevent spurious operations of valves and other equipment which are normally aligned in their safe shutdown position, the operators will trip the power supplies to these devices upon reaching the RSS facilities.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 10 Section 3.1 Page 3.1-7 3.1.10 Fire Areas The "Fire Protection Program Evaluation and Comparison to Branch Technical Position APCSB 9.5-1, Appendix A" report establishes fire areas and zones for purposes of fire detection and protection. Although these zones are satisfactory for fire detection and protection, they do not in all cases satisfy Appendix R requirements. To assure that the Appendix R separation requirements are satisfied, zones containing redundant equipment which do not satisfy the requirements are grouped and analyzed to provide assurance that safe shutdown can be achieved. An example of this is containment which has three zones: C -F-l-Z, C-F-2-Z and C-F-3-Z. As there is no 3 -hour rated barrier between zones, they have been considered as one fire area. The delineation of the fire areas and zones which have been combined into a fire area is in Section 3.2.7. 3.1.11 Emergency Lighting Emergency lighting units per Appendix R, Paragraph III J are provided with at least an 8 -hour battery powered supply or diesel generator backed essential lighting (See letter SBN -932, dated January 27, 1986, Deviation No. 10) in all areas needed for operation of safe shutdown equipment and in access and egress routes. In areas where actions are required after eight hours and actions are needed during a cooldown, 8 -hour battery powered supplied lights are not provided. Repairs per Appendix R III G.l.b, will be implemented to provide required illumination for required cooldown actions. 3.1.12 Repairs for Cold Shutdown For cold shutdown, the following equipment will require replacement of control fuses which will be available in the Train B switchgear room.

a. EAH-FN-31B b. RC-V87 c. RC-V88 d. RH-P-8B e. SI-V17 f. SI-V47 In the event that emergency bus EDE

-SWG-5 is not available, a temporary power connection will be provided from EDE -MCC-621 to the RC -V88 MCC cubicle.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 10 Section 3.1 Page 3.1-8 In the event that PCCW cooling is lost to containment due to loss of containment instrument air causing inboard PCCW isolation valve closure, IA -V530 will be manually opened via a pneumatic jumper to supply outside containment instrument air to containment instrument air to reopen the inboard PCCW isolation valves to reestablish PCCW cooling flow to support containment habitability.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-1 3.2 MAIN CONTROL ROOM SAFE SHUTDOWN 3.2.1 Main Control Room Safe Shutdown Locations Safe shutdown will be accomplished with control from the main control room (MCR), utilizing the safe shutdown equipment and depending on the location of the fire, a combination of the following locations:

a. Train A Switchgear Room

b. Train B Switchgear Room

c. Diesel Generator Room A

d. Diesel Generator Room B

e. Primary Auxiliary Building El. 25

'-0" Boric Acid Storage Tank Area

f. Primary Auxiliary Building El. 7

'-0" Charging Pump Rooms

g. Containment

h. Equipment Train A Vault (Vault #1)

i. Equipment Train B Vault (Vault #2)

j. Mechanical Penetration Area

k. Emergency Feedwater Pump Building

l. Condensate Storage Tank

m. Control Room HVAC Equipment and Duct Area

n. Non-Essential Switchgear Room

o. Turbine Building Actions from the various areas would be of the following types: manual valve actuations, manual damper actuations, tripping of power supplies, opening of doors to provide air flow for cooling, realign power supplies, and/or manipulation of control switches.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-2 The term "prompt action " refers to an action taken after receipt of a valid fire alarm in the main control room. The term "expeditious action" or "expeditiously " refers to an action taken quickly upon entry into the applicable safe shutdown procedure. These type actions are considered to be completed prior to a spurious operation of the equipment operated by the prompt and expeditious

actions. Therefore, no associated timing calculation is required for these actions. 3.2.2 Safe Shutdown Functions for Hot Standby The following are PWR equipment necessary for hot standby: 3.2.2.1 Reactor Coolant (RC) Inventory and Pressure Control To compensate for miscellaneous RC system leakage, RC pump seal leakage and cooldown volume shrink, portions of the chemical and volume control (CS) system including centrifugal charging pumps, boric acid transfer pumps, and a borated water supply, either the refueling water storage tank (RWST) or the boric acid tanks (BAT) are used. The injection path to the RC system will be either through the seal injection flow path or the high head injection flow path. The preferred seal injection path requires that a flow control valve (CS -FCV-121) and that a minimum of two of the four seal injection valves (CS -V154, CS-V158, CS-V162 or CS -V166) be operable. Additionally, the normal charging flow path to the RC system is isolated. This can be accomplished by use of any one of three functionally redundant valves (CS -V142, CS-V143 or CS-HCV-182). Should the seal injection path not be operable, e.g., due to spurious closure of a flow path valve (CS -FCV-121) the high head injection flow path (SI -V138 or SI -V139) can be utilized initially to maintain hot standby by batch charging from the RWST to maintain pressurizer level. Should SI -V-138 or SI -V-139 spuriously open, the charging pump may have to be stopped to prevent overfill of the pressurizer. During cooldown as RC system pressure decreases, it is necessary to provide a flow restricted path to prevent charging pump cavitation. This is due to the limited flow capability from the BAT. If the high head injection path cannot be isolated at this time and/or if the flow controlled path through CS -FCV-121 is not operable, a capability is provided to manually align and throttle the charging pumps to the seal injection flow paths. The necessary operator actions and valve alignments are unique for each fire area where these flow paths are affected and are described in the analysis for each area. RC pump seal cooling is provided by a redundant thermal barrier cooling system. Should the redundant thermal barrier system not be available, the seals will be cooled by the seal injection capability. On a long term basis, seal injection will be restored. The reactor coolant pumps (RCPs) are stopped from the main control board. Circuit analysis shows that the RCPs can not spuriously restart due to fire -induced cable damage.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-3 The RC system pressure is controlled by use of a portion of the RC system which includes the pressurizer heaters (Group A and B) to increase pressure and the pressurizer power operated relief valves (PORV) which depressurize the RC system by discharging reactor coolant fluid to the pressurizer relief tank (PRT). Considering worst case scenarios for spurious actuation of affected equipment, the required times for operator actions regarding RC inventory and pressure control for safe shutdown from the main control room are provided below: Action Time Close PORV block valve Prompt Isolate letdown 15 minutes Swap charging pump suction from VCT to RWST 15.4 minutes. Should SI -V138, SI-V139, or CS -HCV-182 spuriously open, this action must be completed no later than 5.0 minutes following letdown line isolation. Trip RCPs 10 minutes Open a PORV to reduce pressurizer pressure in the event of spurious pressurizer heater operation or trip

pressurizer heaters 23 minutes Start a charging pump, or open a high head safety injection valve SI -V-138 or SI -V-139 if normal charging pump path is not available 31.1 minutes Isolate charging flow, except for seal injection 35.4 minutes Trip spuriously operating containment building spray pumps 46 minutes Trip spuriously operating SI pump < 4 hours, prior to commencement of plant cooldown Isolate the potential diversion path from the BAT to the RWST, or align BAT for gravity feed.

<4 hours, prior to commencement of plant cooldown

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-4 Action Time Align BAT for makeup source

<4 hours, prior to commencement of plant cooldown 3.2.2.2 Reactivity Control Reactivity for hot standby at normal operating temperature (not) is provided by insertion of the control rods. Reactivity conditions required for cooldown and maintaining cold shutdown are provided by a portion of the chemical and volume control (CS) system which includes a centrifugal charging pump taking suction from the BAT

's either utilizing the gravity flow path or the boric acid transfer pumps. During cooldown, the borated water source must be the BAT volume until exp ended to at least the point that the volume injected or a boron sample demonstrates that sufficient shutdown margin for cold shutdown has been achieved, at which time the RWST would be aligned. If gravity feed from the BAT is used, the RWST must be isolated. Considering worst case scenarios for spurious actuation of affected equipment, the required times for operator actions regarding reactivity control for safe shutdown from the main control room are provided below: Action Time Trip the Reactor Expeditiously Provide borated water from the BATs, via boric acid transfer pump or gravity feed

<4 hours, prior to commencement of plant cooldown Isolate boric acid flow diversion path
<4 hours, prior to commencement of plant cooldown

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-5 3.2.2.3 Decay Heat Removal The reactor coolant (RC) system temperature is controlled by use of portions of the feedwater (FW) system and the main steam (MS) system. The main steam safety/relief valves will maintain a heat dump capability. The steam generator water inventory is controlled by operating the motor driven emergency feedwater pump, the start -up feedwater pump, and associated valves. Inventory for the emergency feedwater is from the condensate storage tank. Long term water capability exists using a temporary connection between the suction of the turbine driven emergency feed pump and the fire protection system but is not required to meet Appendix R requirement. This temporary connection back feeds to the CST which supplies water to the startup feedwater pump and the motor driven emergency feedwater pump. To assure main steam system integrity the MSIV 's and MSIV bypass valves are maintained closed. The MSIV bypass valves are normally locked closed and depowered with breakers locked open to preclude spurious opening. Decay heat transfer is made possible by natural convection flow in the RC system. Considering worst case scenarios for spurious actuation of affected equipment, the required times for operator actions regarding decay heat removal for safe shutdown from the main control room are provided below: Action Time Isolate the MSIVs Expeditiously following a reactor trip Place the mode selector switches for the ASDVs to the closed position Prompt Gain Control of excessive Emergency Feedwater Flow 20 minutes Start motor driven EFW pump or startup feedwater pump to preclude steam generator dry out - normal power operation 39 minutes Start motor driven EFW pump or startup feedwater pump to preclude steam generator dry out - low power operation 75 minutes Time to bypass the startup feed pump low suction trip 4 hours SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-6 Action Time Time allotted for operator actions to preclude emptying CO tank to accommodate RHR Cut -in, and ultimately achieve cold safe shutdown within 72 hours 9 hours; 4 hours at hot standby plus

5 hours cooldown to RHR Cut -in 3.2.2.4 Process Monitoring Instrumentation is provided at the main control room for monitoring the following process variables:

a. Steam generator emergency feedwater flow

b. Reactor coolant loop hot and cold leg temperatures

c. Steam generator wide

-range level

d. Steam generator pressure

e. Pressurizer level

f. Pressurizer pressure

g. Wide-range neutron monitoring (excore)

h. Primary component cooling water temperature

i. Boric acid tank level

j. Condensate storage tank level 3.2.2.5 Service Water The service water system will supply cooling water to the primary component cooling water system, diesel generators, and if required, fire protection system. Service water supply will be from the service water pumps taking suction from the tunnels to the ocean. If necessary, transfer to the cooling towers utilizing the cooling tower fans, cooling tower pumps and associated motor-operated transfer valves can be accomplished automatically on low service water pump discharge header pressure or manually from the main control room. If a manual transfer to the cooling tower is in effect and a loss of offsite power occurs, cooling tower operation automatically resumes upon restoration of electrical power.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-7 3.2.2.6 Primary Component Cooling Water (CC) The CC system is utilized to maintain cooling water to the charging pumps, RHR pumps, RHR heat exchangers, containment structure cooling units, containment enclosure cooling units and reactor coolant pumps (RCP) thermal barrier heat exchanger. The PCCW pumps, temperature control valves, RCP thermal barrier cooling pumps, and inboard and outboard containment isolation valves are necessary for system operations. 3.2.2.7 Sampling Sampling of the reactor coolant system is not required at hot standby and cold shutdown conditions since make -up during cool -down will only be provided to the RCS from the boric acid tanks (two) which are maintained at 4 wt% boric acid. During all phases of cooldown, the core will be maintained to the shutdown margin greater than or equal to the limit specified in the Core Operating Limits Report (COLR). 3.2.2.8 Diesel-Generator Building Air Handling (DAH) The DAH system is utilized to maintain long -term habitability and equipment protection for the diesel-generator rooms. The DAH system includes the fans and dampers for air handling in these areas. 3.2.2.9 Containment Enclosure Air Handling (EAH) The EAH system is utilized to maintain long -term habitability of the mechanical penetration area, and provides equipment cooling in the charging pump rooms, and the hydrogen analyzer and electrical room. The EAH system includes the coolers, fans, and dampers required for air handling in these areas. 3.2.2.10 Emergency Feedwater Pumphouse Air Handling (EPA) The EPA system is utilized to maintain long -term habitability and equipment protection in the emergency feedwater pump building. The EPA system includes the fans and dampers required for air handling in this area. 3.2.2.11 Primary Auxiliary Building Air Handling (PAH) Portions of the PAH system are utilized to maintain long -term habitability and equipment protection in the PCCW area of the primary auxiliary building. The PAH system includes the fans and dampers required for ventilation in this area.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-8 3.2.2.12 Service Water Air Handling (SWA) Portions of the SWA system are utilized for equipment protection in the SW pump house electrical control rooms. The SWA system includes the fans and dampers required for air handling in these areas. 3.2.2.13 Electrical Distribution Emergency (EDE) Portions of the EDE system are required to power the various pumps, fans, valves, etc. required for Safe Shutdown. Included in the EDE system are the 4160 Volt ac emergency switchgear, 460 Volt ac emergency unit substations and motor control centers, the uninterruptible power supplies, the static transfer switches, 120 Volt ac vital distribution panels, 125 Volt dc batteries, battery chargers, and 125 Volt dc distribution panels. 3.2.2.14 Diesel-Generators (DG) The diesel -generators provide power to the emergency electrical distribution system upon loss of off-site power. The DG system includes the diesels, generators, control panels, engine -driven auxiliaries fuel oil transfer pumps, starting air compressors and backup operating air compressors. 3.2.2.15 Safeguard Actuation System The safeguard actuation system could be actuated, depending on the fire area. A portion of this system is used to deactivate the system for recovery. 3.2.2.16 Service Air (SA) and Instrument Air (IA) Portions of the SA and IA systems are required for air operated valves and dampers necessary for safe shutdown. 3.2.2.17 Control Building Air Handling (CBA) The CBA system is used to maintain Control Building habitability and equipment protection. The CBA system is comprised of a non -safety related chilled water system that can be aligned to either safety related air handling unit and two redundant safety related chilled water systems, which are aligned to their corresponding safety related air handling units. Each chilled water system includes its own packages chiller and circulating pumps. The air handling units include cooling coils (safety related and non -safety related), fans, dampers. Fires that could disable either safety related train of Control Room cooling are discussed in applicable fire area analysis.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-9 3.2.2.18 Communication The Gaitronics or radio systems are used to announce the fire event and dispatch the fire brigade. The Gaitronics system is also used to provide a fire alarm. For shutdown from the main control room (MCR), most of the operator actions are actually performed in the MCR where face -to-face communication would be used. When field actions are required, an operator would: a) be dispatched to take the required action, b) go to the field and take the action, and c) then return to the MCR and report the action completed. No other communication methods are credited for shutdown controlled from the main control room. Radios and Gaitronics are not credited but would be used as additional means of communication, if not damaged by the fire. 3.2.3 Safe Shutdown Function for Cooldown The following equipment in addition to that which is listed in Section 3.2.2 is necessary for cooldown. 3.2.3.1 Decay Heat Removal In addition to equipment discussed in Section 3.2.2.3, the steam generator atmospheric relief valves will be used for cooldown until the residual heat removal (RH) system can be used. The residual heat removal system will be the long term heat sink at the end of cooldown. An RH pump will be operated along with various control, manual and motor operated valves. Also, the startup feedpump low suction pressure trip must also be bypassed prior to commencing cooldown. 3.2.3.2 Containment Building Air Handling (CAH) The CAH system is utilized to maintain habitability of containment for manual operation of the RHR and SI isolation valves. The CAH system includes six containment cooling units and their associated fans. 3.2.3.3 Sample System For cold shutdown, the operator will draw a manual sample from RH system to verify boron concentration before line -up to RCS. The operator will use manual valves in RH system.

General Area Analysis The following protective measures are inherent in the existing containment design:

a. The significant in situ combustibles are limited to the reactor coolant pump lubricating oil, hydraulic snubbers, cables in trays, and EPDM rubber (debris interceptor trim).

b. An oil collection system is provided for the reactor coolant pumps.

c. Each hydraulic snubber contains 3.5 gallons of a high flash point, high auto ignition point silicon

-based hydraulic fluid. The snubbers are designed to withstand an SSE without failure. Even if leaks were to develop, studies performed at Factory Mutual Research Corporation have shown that a heat flux of 16 kW/M2 is necessary to ignite a high flash point hydraulic fluid similar to the silicon based fluid. It would require the introduction of a transient combustible to containment to provide this heat flux.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-25 d. Containment is inaccessible during normal operation with the exception of operator tours. Because of this, transient combustibles are not considered as a fire hazard. This absence of transient combustibles removes the ignition source for the cables, the hydraulic fluid, and the EPDM rubber.

e. Prior to plant start

-up administrative controls will assure the removal of transient combustibles which could be brought into containment during plant shutdowns.

f. Charcoal filter CAH

-F-8 has an early fire detection system internal to the filter.

2. System Analysis

a. Containment Structure Cooling Units CAH

-AC-1A through 1F (Fans CAH-FN-1A through 1F, Speed Changers CAH -JV3-43 through CAH -JV8-43 and CC Flow Switches CC -FISL 2122 through CC -FISL-2224) Cables for the redundant cooling unit fans, speed changers and flow switches are routed through trays and conduits from the penetration where they enter containment to the cooling units. The trays are separated by concrete floors except between Columns 2 and 4, Columns 5 and 6, Columns 7 and 8, Columns 12 and 13, Columns 14 and 15, and Columns 17 and 18 where there is grating. Between Columns 2 and 4, the Train B trays are a minimum of 12 ' above floor elevation ( -) 26'-0" and a maximum of 19 ' above floor elevation ( -) 26'-0". The Train A trays are a minimum of 11 ' above the grating elevation 0 '-0". There is a minimum of 18 ' of vertical separation between the redundant trays. Even if the redundant trays are affected by a fire, only two Train B and one Train A cooling unit could be affected, the other three cooling units would continue to be operable. Between Columns 5 and 6, the Train B trays are a minimum of 14' above floor elevation ( -) 26'-0" and a maximum of 19 ' above floor elevation ( -) 26'-0". The Train A trays are a minimum of 18 ' above the grating elevation 0 '-0". There is a minimum of 24 ' of vertical separation between the redundant trays. Even if the redundant trays were affected by a fire, only one Train A and one Train B cooling units could be affected; the other four cooling units would continue to be operable. Between Columns 7 and 8, only one Train A cooling units ' cables are routed. There are no Train B cooling units ' cables at this location.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-26 Between Columns 12 and 13, only one Train A and one Train B cooling units ' cables are routed. The other four cooling units would continue to be operable. Between Columns 14 and 15, the Train B trays are a minimum of 19 ' above floor elevation ( -) 26'-0" and a maximum of 21 ' above floor elevation ( -) 26'-0". The Train A trays are a minimum of 17 ' above the grating elevation 0 '-0". There is a minimum of 22 ' of vertical separation between the redundant trays. Even if the redundant trays were affected by a fire, the only two Train A and one Train B cooling unit could be affected. The other three cooling units would continue to be operable. Between Columns 17 and 18, the Train B trays are a minimum of 12 ' above floor elevation ( -) 26'-0" and a maximum of 19 ' above floor elevation ( -) 26'-0". The Train A trays are a minimum of 11 ' above the grating elevation 0 '-0". There is a minimum of 18 ' of vertical separation between the redundant trays. Even if the redundant trays were affected by a fire, only two Train A and one Train B cooling units could be affected; the other three cooling units would continue to be operable. A maximum of three containment structure cooling units (CAH) are needed to maintain habitability of the containment. This can be any combination of Train A and B units. At all points discussed above where Train A and B cables are run near each other without concrete floor separation, there is a minimum of 18 ' of vertical separation, with the Train B cables a minimum of 12 ' off the floor. This vertical separation, the height of the cable from the floor and the lack of combustibles provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. Additionally, a fire at any of these points would affect a maximum of three out of six units, leaving three to cool containment.

b. Thermal Barrier Pumps CC

-P-322A and CC -P-322B Cables for the redundant thermal barrier pumps are routed through trays and conduits from the penetration where they enter containment to the pumps at elevation ( -) 26'-0". The trays are separated by concrete floors except between Columns 17 and 18 where there is a grating. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-27 Between Columns 17 and 18, the Train B trays are a minimum of 12 ' above floor elevation ( -) 26'-0" and a maximum of 19 ' above floor elevation ( -) 26'-0". The Train A trays are a minimum of 11 ' above the grating elevation 0 '-0". There is a minimum of 18 ' of vertical separation between the redundant trays. The only in situ combustibles at this location are the cables in trays. The conduit to the Train A pump is routed such that there is a minimum of 6 ' horizontal separation from the Train B tray that contains the redundant cable. The conduit is run approximately 22 ' above elevation ( -) 26'-0" to the point that it drops down to the Train A pump. The pump is located 6 ' above elevation (-) 26'-0" between Columns 17 and 18. The Train A pump is separated from the tray containing the cable to the Train B pump by a horizontal distance of 6 ' and a vertical distance of 9 '. In addition there are two totally enclosed instrument trays below the Train B tray. Should the thermal barrier cooling be unavailable, the redundant seal injection cooling capability located in other plant fire areas will satisfy the safe shutdown requirements. The separation height of cable from the floor and lack of in situ combustibles provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. The redundant seal cooling satisfies the safe shutdown requirements.

c. Component Cooling Isolation Valves CC

-V57, CC-121, CC-V176, CC-V256 Cables for the redundant valves are routed through trays and conduits from the penetration where they enter containment to the valves on the west side of containment at elevation 4 '-0". The trays are separated by a concrete floor, except between Columns 17 and 18 and between Columns 14 and 15 where there is grating. Between Columns 17 and 18, the Train B trays are a minimum of 12 ' above floor elevation ( -) 26'-0" and a maximum of 19 ' above floor elevation ( -) 26'-0". The Train A trays are a minimum of 11 ' above the grating elevation 0 '-0". There is a minimum of 18 ' of vertical separation between the redundant trays. The only in situ combustibles at this location are the cables in the trays.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-28 Between Columns 14 and 15, the Train B trays are a minimum of 19 ' above floor elevation ( -) 26'-0" and a maximum of 21 ' above floor elevation ( -) 26'-0". The Train A trays are a minimum of 17 ' above the grating elevation 0 '-0". There is a minimum of 22 ' of vertical separation between the redundant trays. The only in situ combustibles at this location are the cables in the trays. The Train A valves CC -V57 and CC -V121 are located between Columns 14 and 15 approximately 4 ' above the grating elevation 0 '-0". The cables for the Train B valves CC -V176 and CC -V256 are routed in trays which are a minimum of 19 ' above floor elevation ( -) 26'-0". There is a minimum of 8 ' vertical separation between the Train B trays and the Train A valves. The only in situ combustibles at this location are the cables in the trays. The Train B valves CC -V176 and CC -V256 are located between Columns 12 and 13 approximately 4 ' above the grating elevation 0 '-0". Although the cables for the redundant Train A valves are not in this location, the power cables for Train A containment structure cooling unit CAH -AC-1E are routed in this area such that a fire could impact four of the six cooling units. However, the cables are routed in tray 19' above the grating elevation 0 '-0" and then in conduit to the cooling unit. There is a vertical separation of approximately 15 ' between valves CC -V176 and CC-V256 and the Train A trays. The only in situ combustibles at this location are the cables in the tray. One set of redundant valves is needed to provide component cooling water to one train of containment structure cooling units. Between Columns 17 and 18, the vertical separation is 18 ' with the lower cables 12' off the floor. The separation and height of cable from the floor provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. Between Columns 14 and 15, there is a vertical separation of 27 ', with the lower cables 19 ' off the floor. There is a minimum separation of 8 ' between the Train A valves and the Train B cables, with the Train B cables 19 ' off the floor. The separation, height of cable from the floor and lack of in situ combustibles provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-29 Between Columns 12 and 13, there is a vertical separation of 15 ' between the Train B valves and the Train A cable. The valves are 30 ' off the floor (Elevation (-) 26'-0"). The separation, height of the valves off the floor and lack of in situ combustibles provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. d. Component Cooling Head Tank Level Transmitters CC -LT-2172-1, 2, 3, CC-LT-2272-1, 2, 3, CC -LT-2192-1, 2, 3, CC -LT-2292-1, 2, 3 and Associated Flow Switches CC -FISHL-2147, CC-FISHL-2248, CC-FISHL-2247, CC-FISHL-2148 Cables associated with CC heat tank level transmitters which affect the Loop B outboard isolation valves CC -V175 and CC -V257 are routed in the same trays as the Loop A inboard isolation valves CC -V57 and CC -V121. Failures in these cables could cause total loss of PCCW to containment by initiation of a spurious

lo-lo head tank level signal. Loop B PCCW can be re -established by transferring control of valves CC -V175 and CC-V257 to local control at the RSS panel in fire area CB-F-1A-A. This removes the lo -lo head tank level isolation function and allows operators to re -open the valves. Cables associated with CC head tank level transmitters which affect the Loop A

outboard isolation valves CC -V122 and CC -V168 are routed in proximity to trays containing cables for the Loop B inboard isolation valves CC -V176 and CC-V256. Failures in these cables could cause total loss of PCCW to containment by initiation of a spurious l o-lo head tank level signal. Loop A PCCW can be re -established by transferring control of valves CC -V122 and CC-V168 to local control at the RSS panel in fire area CB -F-1B-A. This removes the lo-lo head tank level isolation function and allows operators to re-open the valves. The provision of a capability to isolate the affected portion of the circuit and

re-position the valves from another fire area satisfies the safe shutdown requirements.

e. Thermal Barrier Isolation Valves CC

-V395, CC-V428, CC-V438, CC-V439 Valves CC -V395, CC-V428, CC-V438 and CC -V439 are normally open valves which must remain open for safe shutdown. The valves are permanently disabled in the open position. The disabling of the above valves satisfies the safe shutdown requirements.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-30 f. Air Compressors and Dryers SA -C-4A, SA-C-4B, IA-D-2A, IA-D-2B and Associated Distribution Panels, Control Panels and Contactors The air compressors and their associated dryers located at elevation 0 '-0" are required only for instrument air to the primary component cooling water containment isolation valves. These valves are required to remain operable only for containment entry when manual operation of the safety injection accumulator isolation valves SI -V3, SI-V17, SI-V32, and SI -V47 and RHR inlet isolation valves RC -V22, RC-V23, RC-V87 and RC -V88 is required. The redundant air compressors and dryers are within 4 ' of one another. The Train B cables are routed in conduit from the compressors through the floor to the Train B trays. The Train B cable is routed in conduit from the air dryer to the power panel. The only in situ combustibles at this location are the cables in trays. A cross connection to the plant instrument air system is provided to back up the containment instrument air system in the event of a compressor failure. Containment isolation is provided by an air operated, fail closed valve (outboard) and a check valve (inboard). The outboard valve is operable from the Main Control Board. The cross connection is not relied upon to achieve hot/cold shutdown for containment fires and is only described here due to its potential use as a backup. The cable and control circuits are not considered Appendix R equipment and are, therefore, not listed in the respective tables. The Train A cables to valves SI -V3 and RC -V88 are routed in power and control trays a minimum of 17 ' above floor elevation 0 '-0" in the vicinity of the Train B air compressor and dryer. The trays are effectively shielded from the compressor and dryer by a 5 ' wide by 3 ' high steel ventilation duct located 8 ' above the floor between the compressor/dryer and the trays. Should the cables to valve SI-V3 fail, the accumulator can be vented by use of Train B valves SI -FV-2475 and SI-FV-2476. Further discussion of the separation between these cables is provided in Paragraph "n". Failure of the cables to RC -V88 will not prevent safe shutdown as functionally redundant valve RC -V23 will still be operable. The Train A cables to valve RC -V23 are routed in tray and conduit a minimum of 20' horizontal from the Train B air compressors and dryers and are separated by a concrete floor when they are in proximity to the equipment. The Train B cables to valves SI -V47, RC-V22 and RC -V87 are routed in trays which are separated from the Train A air compressor and dryer by a concrete floor. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-31 The cables to Train A Valve SI -V32 and Train B valve SI -V17 are routed on the opposite side of containment from the air compressors. The separation distance, radiant shielding provided by ventilation duct and lack of in situ combustibles between the air compressors/dryers and the cabling for the valves that must remain operable should the redundant compressors/dryers be damaged due to a fire provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. g. RC Pump Seal Water Isolation Valves CS -V10, CS-V28, CS-V44, CS-V59, CS-V168, and CS - Charging to RC Isolation Valves CS -V177, CS-V185 Valve CS-V168 is a normally open valve which should remain open for safe shutdown. Spurious isolation of the Train B valve CS -V168 could result in loss of RC inventory through the upstream relief valve, if CS -V10, CS-V28, CS-V44 and CS-V59 cannot be closed. This inventory is directed to the PRT and is therefore, non -recoverable. However, the postulated flow rate (12 gpm) coupled with the RCS volume shrink over the cooldown period to 350F (approximately 5 hours) is within the capabilities of the boric acid tanks. Cooldown below 350F to cold shutdown can be accomplished using the RWST. Shutdown margin is assured in all phases of this cooldown. The safe shutdown requirements are satisfied.

h. Letdown Isolation Valves CS

-V175, CS-V176, CS-V145, RC-LCV-459, RC-LCV-460 1) Excess Letdown Line Functionally redundant Train B series valves CS -V175 and CS -V176 are normally closed and remain closed for safe shutdown. The spurious opening of one valve will not prevent safe shutdown. The operators will prevent further spurious operation by tripping the power supply breakers for CS -V175 and CS -V176 at the Train B switchgear room (Fire Area: CB -F-1B-A). SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-32 2) Normal Letdown Line Functionally redundant Train A series valves CS -V145, RC-LCV-459 and RC-LCV-460 are normally open and are required to close for safe shutdown. CS -V145 can be closed from the main control room. Should this valve not close due to spurious operation, the operators can close either RC -LCV-459 or RC -LCV-460 by tripping their power supply breakers at the Train A switchgear room (Fire Area: CB -F-1A-A). This will prevent further spurious operation. The capability to isolate the letdown flow paths and mitigate spurious operations from outside the fire area satisfies the safe shutdown requirements.

i. Charging Pump Test Line Isolation Valves SI

-158, SI-159 On spurious operation of either of the normally closed, fail closed valves SI -V158 (Train B) or SI-V159 (Train A), the operators will isolate the high head injection path by closing SI -V138 and SI -V139. Charging will then be accomplished utilizing the seal injection path through valves CS -V154, CS-V158, CS-V162 and CS-V166 located in Fire Zones PP -F-1A-Z and PP-F-5B-Z. The operators can close SI-V158 and SI -V159 by tripping their power supply breakers in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The capability to provide charging to the RC System through a minimum of one flow path satisfies the safe shutdown requirements.

j. Head Vent Valves RC

-FV-2881 and RC -V323 Functionally redundant Train B series valves RC -FV-2881 and RC -V323 are normally closed and remain closed for safe shutdown. The spurious opening of one valve will not prevent safe shutdown. The operators will prevent further spurious operation by tripping the power supply breakers for RC -FV-2881 and RC-V323 at the Train B switchgear room (Fire Area: CB -F-1B-A). The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-33 k. Pressurizer Heaters RC -E-10 and Terminal Boxes EDE -TBX-X44, EDE-TBX-X47 Cables for the redundant pressurizer heaters are routed through trays from the penetration where they enter containment to the heaters at the pressurizer. The trays are separated by concrete floors and walls from the penetration to a point 20 ' from the pressurizer except between Columns 2 and 3 where there is grating. Between Columns 2 and 3, the Train B cables are routed in trays which are a minimum of 10 ' above floor elevation ( -) 26'-0". The Train A cables are routed in trays a minimum of 18 ' above the grating elevation 0 '-0". There is a minimum of 25' vertical separation between the redundant trays. The only in situ combustibles at this location are the cables in the trays. In the area near the entrance to the pressurizer cubicle, the Train B trays are 12 ' above floor Elevation ( -) 26'-0. There is a spatial separation of approximately 6 ' between the redundant trays. The only in situ combustibles at this location are the cables in the trays. The Train A trays are 8 '-4" above the floor and the Train B trays are 18 '-6" above the floor at the entrance of the pressurizer cubicle. This is a vertical separation between redundant trays of over 8 '. Inside the cubicle, the cables are routed in enclosed wireways up to the point where they are routed to the individual pressurizer heater connections. The heaters are located over 20 ' above the floor. There are no in situ combustibles in the pressurizer heater cubicle. The containment is a controlled entry area and the fire loading is very low. The use of transient combustibles is strictly controlled. Where the grating exists, the cables of interest are separated vertically by 25 ' minimum. The lower set of cables are at least 10, off the floor. This separation and the height of the cable from the floor provide acceptable fire protection and provide protection equivalent to the technical requirement of Appendix R. At the area near the entrance to the pressurizer cubicle, there is a spatial separation of 6' between the cables of interest. There are no in situ combustibles. Access to this area is extremely limited during power operation. The separation, lack of combustibles and limited access provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-34 At the entrance to the pressurizer and inside, the case is the same, with the additional factor being the routing of the cables in enclosed wireways up to the point where they are routed to the individual pressurizer heater conditions. The separation, lack of combustibles, limited access and routing of the cables in wireways provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. l. Pressurizer Relief Valves, RC-PCV-456A, RC-PCV-456B, RC-V122 and RC-V124 Cables for the pressurizer relief valves are routed in trays and conduits from the penetration where they enter containment to the valves on the top of the pressurizer. The trays are separated by a concrete floor except between Columns 2 and 4; between Columns 5 and 6; and between Columns 7 and 8 where there is grating. Between Columns 2 and 4, the Train B cables are routed in trays which are a minimum of 10 ' above floor Elevation ( -) 26'-0". Other trays containing Train B cables are located up to 16 ' above floor Elevation ( -) 26'-0". The Train A cables are routed in trays a minimum of 18 ' above the grating Elevation 0 '-0". There is a minimum of 25 ' vertical separation between the redundant trays. The only in situ combustibles at this location are the cables in the trays. Between Columns 5 and 6, the Train B trays are a minimum of 14 ' above floor Elevation ( -) 26'-0" and a maximum of 19 ' above floor Elevation ( -) 26'-0". The Train A trays are a minimum of 18 ' above the grating Elevation 0 '-0". There is a minimum of 24 ' vertical separation between the redundant trays. The only in situ combustibles at this location are the cables in trays; three pints of oil in 15 HP RC drain tank pump motor contributing 56,250 Btu fire load; and five pounds of grease in 3 HP containment sump pump motors contributing 90,000 Btu fire load. Between Columns 7 and 8, the Train B trays are a minimum of 13 ' above floor Elevation ( -) 26'-0" and a maximum of 19 ' above floor Elevation (-) 26'-0". The Train A trays are a minimum of 16 ' above the grating Elevation 0 '-0". There is a minimum of 23 ' of vertical separation between the redundant trays. The only situ combustibles at this location are the cables in trays.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-35 At the pressurizer, the cables are routed in conduit on opposite outside walls of the pressurizer enclosure with a minimum horizontal separation of approximately

15'. The Train A cables are routed in the area of reactor coolant pump C. Near the top of the pressurizer, the conduits enter the pressurizer cubicle and are routed on opposite sides of the cubicle over to the valves. The redundant valves are separated by 2 ' on the top of the pressurizer. There are no in situ combustibles at the top of the pressurizer. Between Columns 2 and 4 and 7 and 8, there is a minimum vertical separation of 23' between Train A and B cables. The Train B cables area minimum of 10 ' off the floor. The separation, height off the floor and lack of in situ combustibles provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. Between Columns 5 and 6, there is a vertical separation of 25 ' with the lower cables 14 ' off the floor. The combustibles are in two motors. The separation, height off the floor, and the enclosure of combustibles in the motors provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. At the pressurizer, the cables are routed in conduit on opposite sides of the pressurizer cubicle. At the top of the pressurizer where the valves are located, there is no access during operation and there are no in situ combustibles. Adequate fire protection is provided and provides protection equivalent to the technical requirements of Appendix R. RC-PCV-456A is a normally closed, fail closed valve whose cables are in this fire area. The spurious opening of a PORV can result in an over -cooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an

unanalyzed condition. The PORV is supplemented with a normally open, series block valve RC -V122. For all fires that have the potential to cause spurious opening of the PORV, the operators will close the block valve by procedure. This will be the first step in the procedure and can readily be accomplished from the main control room. The promptness of this action is justification for the ability to isolate the block valve prior to any spurious valve operations. Under the condition, the initial short will not cause depressurization. To prevent subsequent spurious operations, the operators will de -energize the PORV and the block valve by tripping their power supplies in the Train A switchgear room (Fire Area:

CB-F-1A-A). SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-36 RC-PCV-456B is normally closed, fail closed valve whose cables are in this fire area. The spurious opening of a PORV can result in an over -cooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. The PORV is supplemented with a normally open, series block valve RC -V124. For all fires, that have the potential to cause spurious opening of the PORV, the operators will close the block valve by procedure. This will be the first step in the procedure and can readily be accomplished from the main control room. The promptness of this action is justification for the ability to isolate the block valve prior to any spurious valve operations. Under this condition, the initial short will not cause depressurization. To prevent subsequent spurious operations, the operators will de -energize the PORV and the block valve by tripping their power supplies in the Train B switchgear room (Fire area:

CB-F-1B-A). m. RHR Isolation Valves RC -V22, RC-V23, RC-V87, RC-V88 RHR isolation valves are permanently disabled in the closed position. Redundant valves RC -V23 and RC -V88 are separated by 25 ' with no intervening combustibles other than cables in trays. Redundant valves RC -V22 and RC -V87 are separated by 3 '. These valves are not needed until 9 hours into the event and are only required to be opened for cold shutdown. This can be accomplished manually, if required. Therefore, no fire protection other than the existing separation is needed. Protection equivalent to the technical requirements of Appendix R is provided.

n. Accumulator Tank Outlet Isolation Valve SI

-V3 and Vent Valves SI -FV-2475, SI-FV-2476 Cables for the redundant valves are routed through trays and conduits from the penetration where they enter containment to the valves. The trays are separated by concrete floor except between Columns 17 and 18 where there is grating. The Train A valve SI -V3 is located near column 17 at Elevation ( -) 26'-0" and the Train B, valves SI -FV-2475 and SI -FV-2476 are located near column 16 at Elevation 0'-0". The accumulator isolation valve is separated from its redundant vent valves by approximately 20 ' horizontal with an intervening concrete floor.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-37 At Elevation ( -) 26'-0" the cables to the redundant valves are in proximity such that a fire could affect operation of both trains of equipment. However, the same fire will not prevent the operation of the Train A equipment necessary for containment habitability. These valves are not required to reach or maintain hot standby. They are required to be closed before going to cold shutdown. These valves will be manually closed, if required, prior to decreasing reactor pressure below 600 psig. Prior to this time the accumulators are prevented from injection by reactor pressure acting against a check valve. Manual operation of the isolation valve is only necessary if both the valve circuit and the redundant vent valves are rendered inoperable by the fire. This manual operation can be delayed as much as 9 hours into the event. At Elevation 0 '-0" the cables to the redundant valves are in proximity such that a fire could affect operation of both trains of equipment. Additionally, the redundant air compressors/dryers necessary for containment habitability are in the same area. As discussed above, the valves are not required for 9 hours. To assure that one train of valves can be operated from the MCR or locally, a radiant energy shield is provided around the Train B vent valves and their related cables in the area of the air compressors. The horizontal separation distance between the redundant valves provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. The provision of a capability to manually operate the accumulator isolation valve satisfies the safe shutdown requirements.

Between Columns 7 and 8, the Train B trays are a minimum of 13 ' above floor Elevation ( -) 26'-0" and a maximum of 19 ' above floor Elevation ( -) 26'-0". The Train A trays are a minimum of 16 ' above the grating Elevation 0 '-0". There is a minimum of 23 ' of vertical separation between the redundant trays. The only in situ combustibles at this location are the cables in trays. The Train A Valve SI -V32 is located near column 8 at Elevation ( -) 26'-0" and the Train B valves SI -FV-2477 and SI -FV-2486 are located near column 7 at Elevation 0 '-0". The accumulator isolation valve is separated from its redundant vent valves by approximately 20 ' horizontal with an intervening concrete floor. Between Columns 7 and 8 at Elevation ( -) 26'-0" the cables are in proximity such that a fire could affect operation of both trains of equipment. However, the same fire will not prevent operation of the Train A or Train B equipment necessary for containment habitability. These valves are not required to reach or maintain hot standby. They are required to be closed before going to cold shutdown. These valves will be manually closed, if required, prior to decreasing reactor pressure below 600 psig. Prior to this time the accumulators are prevented from injection by reactor pressure acting against a check valve. Manual operation of the isolation valve is only necessary if both the valve circuit and the redundant vent valves are rendered inoperable by the fire. This manual operation can be delayed as much as 9 hours into the event. Between Columns 2 and 4 and 7 and 8, there is a minimum vertical separation of 23' between Train A and B cables. The Train B cables are a minimum of 10 ' off the floor.

RH Heat Exchanger to CS/SI Pump Isolation Valves RH -V35, RH-V36 Cables for the redundant valves RH -V35 and RH -V36 are routed in proximity to one another in the area of the valves RC -V22, RC-V23, RV-V87 and RV -V88. Valves RH -V35 and RH -V36 are normally closed and their position is in consequential during all modes of plant operation with the exception of cooldown below 350F when the RH system is placed in operation. At that time it is necessary to assure that the valves remain closed. Should one of the valves open spuriously, the operators can disable its power supply in either the Train A or Train B switchgear room (Fire Areas: CB -F-1A-A or CB-F-1B-A) and manually reposition the valves located in the equipment vaults (Fire Zone: RHR -F-4B-Z or RHR-F-2A-Z). Manual operation of the valves can be delayed as much as 9 hours into the event. Therefore, no fire protection other than the existing separation is needed. The provision of a capability to mitigate the spurious operation of the valves outside the fire area satisfies the safe shutdown requirements.

Steam Generator Blowdown Isolation Valves SB -V1, SB-V3, SB-V5, SB-V7 One Train (Train A) of the SG Blowdown isolation valves and their related cables are located in containment. The redundant train (Train B) valves SB -V9, SB-V10, SB-V11 and SB -V12 are located in the main steam and feedwater pipe chase (Fire Zone: MS -F-1B-Z). The Appendix R separation requirements are satisfied.

t. Steam Generator Level Transmitters FW

-LT-501, FW-LT-502, FW-LT-503, FW-LT-504, FW-LT-519, FW-LT-529, FW-LT-537, FW-LT-548 Cables for redundant steam generator level transmitters are routed through enclosed trays and conduits from the penetration where they enter containment to the level transmitters. As only two steam generators are required for safe shutdown, any combinations of two transmitters will satisfy the safe shutdown requirements. At the penetrations in containment the four Train A transmitter cables are separated from the four Train B transmitter cables by a concrete floor. From the penetrations the cables separate such that two Train A and two Train B transmitter cables are routed on each side of the containment up to the transmitters. The transmitters are located approximately 75 ' apart with intervening walls. The separation between redundant transmitters and their cables provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. u. Excore Nuclear Instrumentation NI -NE-6690 and NI -NE-6691 and Terminal Boxes EDE -TBX-XP8, EDE-TBX-XP9 Cables for the redundant nuclear instrumentation are routed through conduit from the penetration where they enter containment to the instruments in the reactor pit. The conduits are separated by concrete floors and walls or by a minimum of 20 ' from the penetration to the reactor pit. The only intervening combustibles between the redundant conduits are cables in trays. The conduits enter the pit approximately 3 ' apart and again separate to turn to their respective instruments, which are 16 ' apart. Because of high radiation, the pit is inaccessible during normal operation. Other than the cable in conduit, the fire loading in this area is zero. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-43 The containment is a controlled entry area and the fire loading is very low. The use of transient combustibles is strictly controlled. The minimum of 20 ' separation and the routing of cables in conduit provide acceptable fire protection in the general containment area. At the entrance to the pit and inside it, the separation, routing of cables in conduit and inaccessibility of the pit due to high radiation, provide acceptable protection and provide protection equivalent to the technical requirements of Appendix R. v. Pressurizer Level Transmitters RC -LT-459, RC-LT-460 Cables for redundant level transmitters are routed in enclosed tray and conduit from the penetration where they enter containment to the level transmitters at Elevation 0 '-0". The trays are separated by concrete floor except between Columns 2 and 4, Columns 5 and 6 and Columns 7 and 8 where there is grating. Between Columns 2 and 4, the Train B trays are a minimum of 8 ' above floor Elevation ( -) 26'-0" and the Train A trays are a minimum of 12 ' above grating Elevation 0 '-0". There is a minimum of 23 ' vertical separation between the redundant trays. The only in situ combustibles at this location are the cables in the trays. Between Columns 5 and 6, the Train B trays are a minimum of 14 ' above floor Elevation ( -) 26'-0" and the Train A trays are a minimum of 18 ' above grating Elevation 0 '-0". There is a minimum of 29 ' vertical separation between the redundant trays. The only in situ combustibles at this location are the cables in trays: three pints of oil in 15 HP RC drain tank pump motor contributing 56,250 Btu fire load; and five pounds of grease in 3 HP containment sump pump motors contributing 90,000 Btu fire load. Between Columns 7 and 8, the Train B trays and conduit are a minimum of 14 ' above floor Elevation ( -) 26'-0" and the Train A trays are a minimum of 14 ' above grating Elevation 0 '-0". There is a minimum of 20 ' of vertical separation between the redundant raceways. The only in situ combustibles at this location are the cables in the trays.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-44 The redundant level transmitters are located 6 ' above the floor at Elevation 0 '-0". They are separated by approximately 1 '-0" horizontally. The Train B transmitter is enclosed in a non -combustible radiant energy shield. The cable to the Train A transmitter is routed in conduit from the enclosed instrumentation tray located 14 ' above the grating Elevation 0 '-0" to the transmitter. The cable to the Train B transmitter is routed in conduit from the enclosed instrumentation tray located 15 ' above floor Elevation ( -) 26'-0" to the level transmitter. The conduit is protected by a radiant energy shield above Elevation 0 '-0" until it enters the enclosure formed by the non -combustible radiant energy shield for RC -LT-460. The combustibles in the area are limited to cables in one stack of open trays (3 trays high) between elevations ( -) 12'-8" and (-) 7'-4" approximately 13 ' above floor Elevation ( -) 26'-0" and one stack of open trays (4 trays high) between elevations 16'-8" and 20'-8" approximately 16 ' above grating Elevation 0 '-0". The separation, height of the tray off of the floor, enclosure of combustibles in the motors and provision of a radiant energy shield provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. w. Pressurizer Pressure Transmitters RC -PT-455, RC-PT-456, RC-PT-457, and RC-PT-458 Redundant channels ' of pressurizer pressure instruments and cables are located in proximity. Spurious operation of two channels will initiate safety injection and containment isolation phase A signals. The operators will have the capability to terminate SI after 1 minute by use of the manual reset and block switch and terminate containment isolation by use of the manual reset switch. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B Switchgear Rooms (Fire Areas: CB-F-1A-A and CB-F-1B-A). The provision of a capability to mitigate the spurious operation of the pressure transmitters outside the fire area satisfies the safe shutdown requirements.

Reactor Coolant Hot Leg Temperature Elements, RC -TE-413A through RC-TE-443B, IC-TE-1 through IC -TE-58, IC-MM-173 and Terminal Boxes EDE-TBX-X40, EDE-TBX-X48, EDE-TBX-X94 Cables for redundant RC hot leg temperature elements are routed through enclosed trays and conduits from the penetration where they enter containment to the temperature elements. As only one hot leg temperature is required for safe shutdown, any of the TE 's can satisfy the safe shutdown requirements. As the TE's are at various locations around the containment, there is a minimum of 20 ' of separation except for the penetration area. At the Train A penetration area, all hot leg TE cables could fail. This function can also be performed by the Train B incore thermocouples IC -TE-1 through IC -TE-58 which are separated from the Train A penetration area by concrete walls and floors. The separation between redundant temperature monitoring capabilities and their associated cables provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. y. Reactor Coolant Cold Leg Temperature Elements RC -TE-413B through RC-TE-443B and Terminal Boxes EDE -TBX-X14 through EDE -TBX-X69 Cables for redundant RC cold leg temperature elements are routed through enclosed trays and conduits from the penetration where they enter containment to the temperature elements. As only one cold leg temperature is required for safe shutdown any one of the TE's can satisfy the safe shutdown requirements except for the penetration area. At the Train B penetration area, all cold leg TE cables could fail. This function can also be performed by the steam generator pressure instruments because cold leg temperature approximates the saturation temperature corresponding to secondary pressure. These pressure transmitters FW -PT-514, FW-PT-525, FW-PT-534 and FW -PT-545 are located in Fire Zones MS -F-3A-Z and MS-F-1B-Z. The provision of a capability to permit RC temperature monitoring outside the fire area satisfies the safe shutdown requirements.

General Systems/Equipment Analysis With the exception of the systems/equipment discussed below, a fire in this area will only affect the Train A safe shutdown equipment and cables. The redundant Train B safe shutdown equipment and cables are located in fire area CB -F-1B-A. The Appendix R separation requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-56 2. Containment Spray Pump CBS -P-9A This pump is not required for safe shutdown, however; a fire could cause a spurious start. The operators will terminate operation of the CBS pump either by tripping and locking out the motor 's circuit breaker from the MCR or by removing all power from the 4160V emergency bus E5. The safe shutdown requirements are satisfied.

3. Component Cooling Water Containment Isolation Valves CC

-V57, CC-V121, CC-V175, CC-V257 and Head Tank Level Transmitters CC -LT-2172-1, 2, 3, CC-LT-2272-1, 2, 3 A fire could cause loss of all PCCW to containment by spurious closure of the PCCW Loop B outboard isolation valves CC -V175 and CC -V257. One train of PCCW is required to maintain containment habitable for manual valve operations. PCCW is also required for cooling air compressor SA -C-4B. Should all PCCW be isolated, the operators will immediately trip the Train B air compressor SA-C-4B to preclude operating the compressor without cooling. As the containment instrument air pressure decays without SA -C-4B operating, the PCCW Loop B inboard isolation valves will close. The operators will manually reopen the PCCW Loop B outboard isolation valves CC-V175 and CC -V257 in the mechanical penetration fire area (Fire Zone: PP-F-4B-Z). The operators will then manually open IA -V530 to connect the outside containment Loop B instrument air to the inside containment instrument air system. Once containment instrument air is restored, the PCCW Loop B inboard isolation valves will reopen to reestablish PCCW cooling to the air compressor and to the Train B containment structure coolers. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-57 4. Reactor Trip Switchgear CP -CP-111 Redundant trains of cables and equipment are located in proximity. These breakers are tripped from the MCR as an initial operator action; however, a fire in the area of the reactor trip switchgear could prevent operation of both trains of tripping capability. Should this occur the operators can remove power from the reactor trip MG sets by tripping the switching station breakers that supply power to the UAT and RAT causing a loss of offsite power to the station. This trip can be initiated from the MCR as the switching station breaker control circuits are not routed through this fire area. The removal of power from the MG sets will, after a short time delay to allow for coastdown, result in de -energizing the reactor trip solenoids and; hence, insertion of the control rods. The safe shutdown requirements are satisfied.

5. Charging Pump Flow Control Valve CS

-FCV-121 and Flow Transmitter CS-FT-121 Under normal conditions, charging is accomplished by utilizing the control valve

CS-FCV-121 and its associated transmitter. Spurious closure of this valve could isolate the seal injection path. In this event the operators will utilize the high head injection path for hot standby charging flow by opening the Train B valve SI-V139. The cables, controls and equipment required for operation of SI -V139 are not contained in the fire area. For cooldown, the operators will manually align the Train B charging pump discharge and bypass valves (CS -V219 and CS -V220) to the seal injection flow path and throttle the bypass valve as required. This operator action can be delayed for up to four (4) hours. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-58 6. RC Pump Seal Water Isolation Valves CS -V10, CS-V28, CS-V44, CS-V59 and CS-V167 Valve CS-V167 is a normally open valve which should remain open for safe shutdown. Spurious isolation of the Train A valve CS -V167 could result in loss of RC inventory through the upstream relief valve. This inventory is directed to the PRT and is therefore, non -recoverable. Additionally, cables for the functionally redundant Train A valves CS -V10, CS-V28, CS-V44 and CS -V59 are routed in proximity. However, the postulated flow rate (12 GPM) coupled with the RCS volume shrink over the cooldown period to 350F (approximately 5 hours) is within the capabilities of the boric acid tanks. Cooldown below 350F to cold shutdown can be accomplished using the RWST. Shutdown margin is assured in all phases of this cooldown. The safe shutdown requirements are satisfied.

7. RC Pump Seal Injection Isolation Valves CS

-V154, CS-V158, CS-V162 and CS-V166 Under normal conditions, these valves are utilized for the seal injection flow path. Spurious closure of one valve will not prevent safe shutdown. The operators will prevent further spurious operations by removing power from the 4160V emergency bus E5. MCC E512, which powers these valves, is fed from emergency bus E5. These valves provide a redundant RC pump seal cooling capability to the safety grade thermal barrier seal cooling. Cables, controls and equipment required for the Train B thermal barrier seal cooling capability are not contained in this fire area. The Appendix R separation requirements are satisfied.

8. SI-CS Suction Cross Connection Valve CS

-V460 Valve CS-V460 is a normally closed Train A valve which is required to remain closed for cooldown. Should this valve open spuriously, the functionally redundant Train B valve CS -V475 can be closed from the MCR. Cables and controls for valve CS -V475 are not located in this fire area. The Appendix R separation requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-59 9. Tower Actuation Logic EDE -CP-248 Failures in TA logic cables or equipment could initiate a spurious tower actuation signal which would transfer Train A service water cooling capability from the pumphouse to the cooling towers. The transfer will not interrupt Train A service water nor will it have any impact on Train B service water. This failure does not prevent safe shutdown. The safe shutdown requirements are satisfied.

10. 4160V Switchgear EDE

-SWG-5 Although this equipment is not required for safe shutdown for fire in this area, there are many loads powered from it whose spurious operation could affect safe shutdown should they remain powered. For any fire in the Train A switchgear room that has a potential to impact safe shutdown, the operators will trip and lockout all ac power supplies (UAT, RAT, DG) to the bus from the MCR. To assure that breakers cannot spuriously reclose, the UAT and RAT breaker dc control power will be disabled at the disabling panel and the DG breaker control power will be disabled at the DG control panel both in the Train A diesel generator room (Fire Area DG -F-2A-A). Should the capability to trip the power supplies not be available due to prior loss of the dc control power, the operators can remove power by tripping the switching station breakers that supply power to the UAT and RAT causing a loss of offsite power to the station. This trip can be initiated from the MCR as the switching station breaker control circuits are not routed through this fire area. Subsequent to this loss of offsite power, the 4160V emergency switchgear bus E6 and Train B power will be supplied by the Train B diesel generator. The safe shutdown requirements are satisfied.

11. Emergency Feedwater Pump Control Valves FW

-FV-4214A, FW -FV-4224A, FW-FV-4234A and FW -FV-4244A These valves are normally open and at least two valves must remain open for safe shutdown. Spurious closure of one valve will not prevent safe shutdown. The operators will prevent further spurious operations by removing power from the 4160V emergency bus E5. MCC E515, which powers these valves, is fed from emergency bus E5. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-60 12. Atmospheric Relief Valves MS -PV-3001, MS-PV-3002, MS-PV-3003, MS-PV-3004 Valves MS -PV-3001, MS-PV-3002, MS-PV-3003 and MS -PV-3004 are normally closed valves. A fire would prevent operation of the Train A capabilities provided for opening and closing these valves. However, the fire would not affect the Train B capabilities and the valves will be operable for safe shutdown. Spurious opening of even one ARV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. Since the ARV 's are air operated valves, their spurious operation will be prevented by assuring that these valves are placed in a state such that the initial spurious operation in the air supply will not cause the valve to open. This will be accomplished by procedure as one of the first steps for any fire

that can affect the integral ARV air system cables. This action is justifiable since it can be accomplished from the main control room. To prevent a subsequent short that could override the initial action and cause the ARV to open, the affected air solenoids will be de -energized from the disabling panel located in Train A diesel generator room (Fire Area: DG -F-2A-A). This will isolate the faulted air supply but will not preclude operation of the ARV since the redundant air solenoids will still be operational. The safe shutdown requirements are satisfied.

13. Volume Control Tank Isolation Valve CS

-LCV-112B and CS-LCV-112D, and Charging Pump CS -P-2A & CS-P-2B Volume control tank (VCT) isolation valves CS -LCV-112B & -112C are normally open to provide a suction path from the VCT to the normally operating charging pump (CS -P-2A or -2B). These valves must stay open until RWST valve CS-LCV-112D or -112E is manually opened to provide a charging pump suction path from the RWST, or the boric acid tanks are manually aligned as a charging pump suction source. Spurious closure of a VCT isolation valve caused by a hot short would interrupt suction flow to the operating charging pump causing it to be damaged. If the standby charging pump has cables in the same area then its operation can also be degraded. The result would be no charging system flow. Since this fire area contains cables for CS -LCV-112B and CS -P-2A, this condition is potentially applicable for the system alignment with CS -P-2A the standby pump and CS -P-2B the operating pump.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-61 There is an electrical interlock that automatically opens opposite train RWST valve 1-CS-LCV-112E if VCT valve 1 -CS-LCV-112B is not full open (i.e., spuriously closes). The cables, controls and equipment required for automatically opening RWST valve 1 -CS-LCV-112E are not contained in this fire area. The open RWST valve provides a suction path so operating charging pump CS -P-2B will not be damaged. Since charging flow is available, the safe shutdown requirements are satisfied.

14. Not Used. 15. Reactor Coolant Pumps RC

-P-1A, RC-P-1B, RC-P-1C and RC -P-1D Cables required for trip of the RC pumps are routed through this fire area. These breakers are tripped from the MCR as an initial operator action; however, fire in this area could prevent this trip. Should this occur the operators will either trip the RC pump circuit breakers locally (Fire Area: NES -F-1A-Z) or by removing power from the RC pump motors by tripping the switching station breakers which supply power to the UAT and RAT, thus causing a loss of offsite power to the station. This trip can be initiated from the MCR as the switching station breaker control circuits are not routed through this fire area. The safe shutdown requirements are satisfied.

16. Pressurizer Relief Valves RC-PCV-456A, RC-V122 RC-PCV-456A is a normally closed, fail closed valve whose cables are in this fire area. The spurious opening of a PORV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. The PORV is supplemented with a normally open, series block valve RC

-V122. For all fires that have the potential to cause spurious opening of the PORV, the operators will close the block valve by procedure. This will be the first step in the procedure and can readily be accomplished from the main control room. The promptness of this action is justification for the ability to isolate the block valve prior to any spurious valve operations. Under the condition, the initial short will not cause depressurization. To prevent subsequent spurious operations, the operators will de -energize the PORV by placing the PORV main control board control switch to the closed position. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-62 17. RHR Isolation Valves RC -V23, RC-V88 RHR isolation valves are permanently disabled in the closed position. For entry into RHR shutdown cooling valve RC -V88 must be opened. This can be accomplished manually by entry into containment, if required. This manual

operation can be delayed as much as 9 hours into the event. The safe shutdown requirements are satisfied.

18. Safety Injection Pump SI

-P-6A This pump is not required for safe shutdown; however, a fire could cause a spurious start. The operators will terminate operation of the SI pump either by tripping and locking out the motor 's circuit breaker from the MCR or by removing all power from the 4160V emergency bus E5. The safe shutdown requirements are satisfied.

19. Cooling Tower Fan SW

-F-51A, Pump SW -P-110A, Valves SW -V54, SW-V56, SW-V139, Fans SWA -FN-69 and Dampers SWA -DP-66 and SWA -FN-71 During normal plant operation, the service water pumphouse is utilized for plant cooling. The cooling towers are considered a redundant capability which may be utilized for a limited period of time during the year (e.g., tunnel heat treating). Should a fire occur during this time period the operators can utilize the Train B service water pumphouse capability. The cables, controls and equipment required for the Train B service water pumphouse capability are not contained in this fire area. The Appendix R separation requirements are satisfied.

20. Pressurizer Heaters Group C, Group D, Control Group This equipment is not required for safe shutdown; however, a fire could cause spurious operations. The operators will terminate operation of the pressurizer heaters, or mitigate the condition by tripping the heaters

' circuit breaker, by tripping off -site power from the control room, or by reducing pressure by opening a PORV. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-63 21. Containment Pressure Transmitter SI -PT-937 A cable for one channel of containment pressure instrumentation is routed through this fire area. This channel inputs to 2 out of 3 and 2 out of 4 logics which initiate protective actions. A spurious signal from one channel is not sufficient to initiate the logic and perform the protective action; hence, a failure in this cable will not prevent safe shutdown. The safe shutdown requirements are satisfied.

22. Containment Enclosure Isolation Damper, PAH

-DP-35A, PAH-DP-36A Cables for dampers PAH -DP-35A and PAH -DP-36A are routed through this area. Under normal operation both dampers are open. If both dampers go closed, the Containment Enclosure Air Handling (EAH) system operates in the recirculation mode. The normal and recirculation modes for EAH system operation both satisfy the safe shutdown function. Independent operation of either damper (one open and one closed) could cause an air flow problem in EAH system. This

assumes that both redundant dampers (PAH -DP-35B and PAH -DP-36B) are in their normal open position since they would not be affected by a fire in this area. Both dampers are powered from a single Train A power supply. The circuit design is such that a spurious signal will cause both dampers to operate together either both open (normal mode) or both closed (recirculation mode). The safe shutdown requirements are satisfied.

23. Control Room Air Conditioning The non-safety related chilled water system, which is powered from a non

-safety related power supply, is normally running and aligned to either the A Train or the B Train Control Building Air Conditioning System fan unit. During normal plant operation, with the non -safety subsystem aligned for Control Room cooling on the A Train fan unit, the control switch on the MCB for the safety related train will be aligned for AUTO operation. On a loss of offsite power, the non -safety chilled water subsystem will be shut down and an automatic start sequence will be

initiated via the emergency diesel generator load sequencer to restart the AC unit and start the A Train safety chiller.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-64 In the event the A Train of the CBA fails to start, operator actions, prompted by high Control Room temperature, are assumed to secure the failed chiller and associated equipment and start the B Train. All controls for the recovery are in the Control Room. The safe shutdown requirements are satisfied.

24. Boration/Dilution Flow Control Valves, CS

-FCV-110A, -111A, -110B, -111B This area contains cables for CS -FCV-110A, -111A, -110B, -111B. Spurious opening of these valves in conjunction with spurious start of a boric acid transfer pump or reactor makeup water pump may divert boric acid from the reactor coolant system affecting cold shutdown reactivity control, or result in an unplanned dilution affecting hot standby and cold shutdown reactivity control. The operators isolate the diversion flow by closing CS -FCV-110B and -111B using the main control board control switches. The operators isolate the dilution flow by closing CS -LCV-112C using the main control board control switch. The safe shutdown requirements are satisfied.

25. Charging Pump CS

-P-2A and High Head Injection Valve SI -V-138 Either charging pump CS -P-2A or CS-P-2B is normally operating. High head injection valve SI -V-138 is normally closed. If SI-V-138 spuriously opens, CS-P-2A and CS -P-2B need to be stopped to isolate charging flow to prevent pressurizer overfill. If CS-P-2A can not be stopped from the main control room because its cables are routed through this fire area, then power will be removed from Emergency Bus E5 to stop the pump (see Item 10 analysis). A fire in this area does not affect the capability to trip CS -P-2B from the main control room. C. Evaluation The safe shutdown requirements and Appendix R separation requirements are satisfied.

The redundant Train A safe shutdown equipment and cables are located in fire area CB -F-1A-A. The Appendix R separation requirements are satisfied.

2. Containment Spray Pump CBS

-P-9B This pump is not required for safe shutdown, however, a fire could cause a spurious start. The operators will terminate operation of the CBS pump either by tripping and locking out the motor 's circuit breaker from MCR or by removing all power from the 4160V emergency Bus E6. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-75 3. Component Cooling Water Containment Isolation Valves CC -V122, CC-V168, CC-V176, CC-V256 and Head Tank Level Transmitters CC -LT-2192-1, 2, 3, CC-LT-2292-1, 2, 3 A fire could cause loss of all PCCW to containment by spurious closure of the PCCW Loop B outboard isolation valves CC -V122 and CC -V168. One train of PCCW is required to maintain containment habitable for manual valve operations. PCCW is also required for cooling the air compressor SA -C-4A. Should all PCCW be isolated, the operators will immediately trip the Train A air compressor SA-C-4A to preclude operating the compressor without cooling. As the containment instrument air pressure decays without SA -C-4A operating, the PCCW Loop B inboard isolation valves will close. The operators will manually reopen the PCCW Loop A outboard isolation valves CC-V-122 and CC -V-168 in the mechanical penetration fire area (Fire Zone: PP-F-4B-Z). The operators will then manually open IA -V50 to connect the outside containment Loop A instrument air to the outside containment Loop B instrument air. The operators will then manually open IA -V530 to connect the outside containment Loop B instrument air to the inside containment instrument air system. Once containment instrument air is restored, the PCCW Loop A inboard isolation valves will reopen to reestablish cooling to the air compressor and to the Train A containment structure coolers. The safe shutdown requirements are satisfied.

4. RC Pump Seal Water Isolation Valve CS

-V168 Valve CS-V168 is a normally open valve which should remain open for safe shutdown. Spurious isolation of the Train B valve could result in RC inventory loss through the upstream relief valves. This inventory is directed to the PRT and is therefore, non -recoverable. To preclude this loss of inventory, redundant isolation capability is provided for the RC pump seal return lines by means of Train A valves CS -V10, CS-V28, CS-V44 and CS -V59. The cables, controls and equipment required for the operation of CS -V10, CS-V28, CS-V44 and CS -V59 are not contained in this fire area. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-76 5. Excess Letdown Isolation Valves CS -V175 and CS -V176 Cables for functionally redundant fail closed valves CS -V175 and CS -V176 are routed in proximity. These valves are normally closed and remain closed for safe shutdown. Should either valve spuriously open, the operators will mitigate the spurious operation by disabling the power supply to CS -V175 at the disabling panel in the Train B diesel generator room (Fire Area: DG -F-2B-A). The safe shutdown requirements are satisfied.

6. Charging Pump Test Line Isolation Valve SI

-V158 On spurious operation of the normally closed, fail closed valves SI -V158 (Train B), the operators will maintain the normally closed high head injection path valves SI -V138 and SI -V139 closed. Charging will be accomplished utilizing the seal injection flow path through valves CS -FCV-121, CS-V154, CS-V158, CS-V162 and CS -V166. The cables controls and equipment required for operation of these valves are not contained in the fire area. The capability to provide charging to the RC System through a minimum of one flow path satisfies the safe shutdown requirements.

7. BAT to Charging Pump Isolation Valve CS

-V426 Valve CS-V426 is a normally closed valve which is opened to provide a path from the boric acid tanks to the charging pump suction. This path is required to begin cooldown. In the event that this valve is inoperable, the operators can provide a redundant path by manually positioning valves in the boric acid tank room (Fire Zone: PAB -F-2B-Z). The operators can maintain the plant in hot standby for the time required to perform this manual action. The safe shutdown requirements are satisfied.

8. SI-CS Suction Cross Connection Valves CS

-V461, CS-V475 Cables for valves CS -V461 and CS -V475 are located in proximity. Prior to beginning cooldown, the normally closed valve CS -V461 valve should remain closed or the functionally redundant valve CS -V475 should be closed. The isolation of this path will prevent the potential loss of boric acid tank inventory to the RWST during cooldown. In the event of a spurious valve operation which renders this flow path open, the plant can be maintained in hot standby for as long as 4 hours.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-77 Should this area be inaccessible due to the fire or should the operators desire to initiate the cooldown sooner than 4 hours, a gravity feed can be established from the boric acid tanks to the charging pumps. As the BAT head is lower than that required to return inventory to the RWST, there would be no loss of BAT inventory through this path and the position of these valves would be inconsequential. The safe shutdown requirements are satisfied.

9. Tower Actuation Logic EDE

-CP-249 Failures in TA logic cables or equipment could initiate a spurious tower actuation signal which would transfer Train B service water cooling capability from the pumphouse to the cooling towers. The transfer will not interrupt Train B service water nor will it have any impact on Train A service water. This failure does not prevent safe shutdown. The safe shutdown requirements are satisfied.

10. 4160V Switchgear EDE

-SWG-6 Although this equipment is not required for safe shutdown for fire in this area, there are many loads powered from it whose spurious operation could affect safe shutdown should they remain powered. For any fire in the Train B switchgear room that has a potential to impact safe shutdown, the operators will trip and lockout all ac power supplies (UAT, RAT, DG) to the bus from the MCR. To assure that breakers cannot spuriously reclose, the UAT and RAT breaker dc control power will be disabled at the disabling panel and the DG breaker control power will be disabled at the DG control panel, both in the Train B diesel generator room (Fire Area: DG -F-2B-A). Should the capability to trip the power supplies not be available due to prior loss of the dc control power, the operators can remove power by tripping the switching station breakers that supply power to the UAT and RAT causing a loss of offsite power to the station. This trip can be initiated from the MCR as the switching station breaker control circuits are not routed through this fire area. Subsequent to this loss of offsite power, the 4160V emergency switchgear bus E5 and Train A power will be supplied by the Train A diesel generator. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-78 11. Emergency Feedwater Pump Control Valves FW -FV-4214B, FW -FV-4224B, FW-FV-4234B and FW -FV-4244B These valves are normally open and at least two valves must remain open for safe shutdown. Spurious closure of one valve will not prevent safe shutdown. The operators will prevent further spurious operations by removing power from the 4160V emergency bus E6. MCC E615, which powers these valves, is fed from emergency bus E6. The safe shutdown requirements are satisfied.

12. Atmospheric Relief Valves MS

-PV-3001, MS-PV-3002, MS-PV-3003, MS-PV-3004 Valves MS -PV-3001, MS-PV-3002, MS-PV-3003 and MS -PV-3004 are normally closed valves. A fire would prevent operation of the Train B capabilities provided for opening and closing these valves. However, the fire would not affect the Train A capabilities and the valves will be operable for safe shutdown. Spurious opening of even one ARV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. Since the ARV 's are air operated valves, their spurious operation will be prevented by assuring that these valves are placed in a state such that the initial spurious operation in the air supply will not cause the valve to open. This will be accomplished by procedure as one of the first steps for any fire that can affect the integral ARV air system cables. This action is justifiable since it can be accomplished from the main control room. To prevent a subsequent short that could override the initial action and cause the ARV to open, the affecte d air solenoids will be de -energized from the disabling panel located in Train B diesel generator room (Fire Area: DG -F-2B-A). This will isolate the faulted air supply but will not preclude operation of the ARV since the redundant air solenoids will still be operational. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-79 13. Reactor Vent Valves RC -FV-2881, RC-V323 Functionally redundant series valves RC -FV-2881 (fail closed) and RC -V-323 are normally closed and remain closed for safe shutdown. The spurious opening of one valve will not prevent safe shutdown. The operators will prevent spurious opening of this path by disabling the power supply to valve RC -FV-2881 at the disabling panel in the Train B diesel generator room (Fire Area: DG -F-2B-A). The safe shutdown requirements are satisfied.

14. Pressurizer Relief Valves RC

-PCV-456B, RC-V124 RC-PCV-456B is normally closed, fail closed valve whose cables are in this fire area. The spurious opening of a PORV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. The PORV is supplemented with a normally open, series block valve RC -V124. For all fires that have the potential to cause spurious opening of the PORV, the operators will close the block valve by procedure. This will be the first step in the procedure and can readily be accomplished from the main control room. The promptness of this action is justification for the ability to isolate the block valve prior to any spurious valve operations. Under the condition, the initial short will not cause depressurization. To prevent subsequent spurious operations, the operators will de -energize the PORV by placing the PORV main control board control switch to the closed position. The safe shutdown requirements are satisfied.

15. RHR Isolation Valves RC

-V22, RC-V87 RHR isolation valves are permanently disabled in the closed position. For entry into RHR shutdown cooling valve RC -V22 must be opened. This can be accomplished by entry into containment, if required. This manual operation can be delayed as much as 9 hours into the event. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-80 16. Safety Injection Pump SI -P-6B This pump is not required for safe shutdown; however, a fire could cause a spurious start. The operators will terminate operation of SI pump either by tripping and locking out the motor 's circuit breaker from the MCR or by removing all power from the 4160V emergency bus E6. The safe shutdown requirements are satisfied. 17. Containment Enclosure Isolation Damper, PAH -DP-35B, PAH-DP-36B Cables for dampers PAH -DP-35B and PAH -DP-36B are routed through this area. Under normal operation both dampers are open. If both dampers go closed, the Containment Enclosure Air Handling (EAH) system operates in the recirculation mode. The normal and recirculation modes for EAH system operation both satisfy the safe shutdown function. Independent operation of either damper (one open and one closed) could cause an air flow problem in EAH system. This assumes that both redundant dampers (PAH -DP-35A and PAH -DP-36A) are in their normal open position since they would not be affected by a fire in this area. Both dampers are powered from a single Train B power supply. The circuit design is such that a spurious signal will cause both dampers to operate together, either both open (normal mode) or both closed (recirculation mode). The safe shutdown requirements are satisfied.

18. Control Room Air Conditioning The non-safety related chilled water system, which is powered from a non

-safety related power supply, is normally running and aligned to either the A Train or the B Train Control Building Air Conditioning System fan unit. During normal plant operation, with the non -safety subsystem aligned for Control Room cooling on the B Train fan unit, the control switch on the MCB for the safety related train will be aligned for AUTO operation. On a loss of offsite power, the non -safety chilled water subsystem will be shut down and an automatic start sequence will be initiated via the emergency diesel generator load sequencer to restart the AC unit and start the B Train safety chiller. In the event the B Train of the CBA fails to start, operator actions, prompted by high Control Room temperature, are assumed to secure the failed chiller and associated equipment and start the A Train. All controls for the recovery are in the Control Room. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-81 19. Volume Control Tank Isolation Valve CS -LCV-112C and CS-LCV-112E, and Charging Pump CS -P-2A & CS-P-2B Volume control tank (VCT) isolation valves CS -LCV-112B & -112C are normally open to provide a suction path from the VCT to the normally operating charging pump (CS -P-2A or -2B). These valves must stay open until RWST valve CS-LCV-112D or -112E is manually opened to provide a charging pump suction path from the RWST, or the boric acid tanks are manually aligned as a charging pump suction source. Spurious closure of a VCT isolation valve caused by a hot short would interrupt suction flow to the operating charging pump causing it to be damaged. If the standby charging pump has cables in the same area then its operation can also be degraded. The result would be no charging system flow. Since this fire area contains cables for CS -LCV-112C and CS -P-2B, this condition is applicable for the system alignment with CS -P-2B the standby pump and the CS -P-2A the operating pump. There is an electrical interlock that automatically opens opposite train RWST valve 1-CS-LCV-112D if VCT valve 1 -CS-LCV-112C is not full open (i.e., spuriously closes). The cables, controls and equipment required for automatically opening RWST valve 1 -CS-LCV-112D are not contained in this fire area. The open RWST valve provides a suction path so operating charging pump CS -P-2A will not be damaged. Since charging flow is available, the safe shutdown requirements are satisfied.

20. Charging Pump CS

-P-2B and High head Injection Valve SI -V-139 Either charging pump CS -P-2A or CS-P-2B is normally operating. High head injection valve SI -V-139 is normally closed. If SI -V-139 spuriously opens, CS-P-2A and CS -P-2B need to be stopped to isolate charging flow to prevent pressurizer overfill. If CS -P-2B can not be stopped from the main control room because its cables are routed through this fire area, then power will be removed from Emergency Bus E6 to stop the pump (see Item 10 analysis). A fire in this area does not affect the capability to trip CS -P-2A from the main control room. C. Evaluation The safe shutdown requirements and Appendix R separation requirements are satisfied.

2. Recirculation Damper CBA

-DP-52 Cables for damper CBA -DP-52 are routed through this area. This damper is normally closed and is required to remain closed for safe shutdown if only one main control room ventilation fan is operating. In the event of a spurious opening of the damper, the operators will isolate and bleed the air line to the dampers air operator and manually re -close the damper by means of a handwheel. The damper and its air supplies are located in the main control room HVAC equipment and duct area (Fire Area: CB -F-3B-A). The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-89 3. Process Control Cabinets MM -CP-153, MM-CP-297A Power cables for PCC cabinets MM -CP-153 and MM-CP-297A are routed through this fire area. The loss of power to these cabinets will result in loss of CST level transmitter CO -LT-4096 and FW -LT-4252 and emergency feedwater flow transmitters FW -FT-4214-2 and FW-FT-4234-2. The Train B CST level transmitter FW -LT-4257 is not affected by a fire in this area. Additionally, the emergency feedwater flow to two steam generators will be available along with steam generator level for all four steam generators. The Appendix R separation requirements are satisfied.

4. Normal Letdown Isolation Valve RC

-LCV-459 Cables for valve RC -LCV-459 are routed in this fire area. The cables, controls and equipment for functionally redundant valve CS -V145 are not contained in this area and; hence, will be available for safe shutdown. The Appendix R separation requirements are satisfied.

5. Control Room Air Conditioning The non-safety related chilled water system, which is powered from a non

-safety related power supply, is normally running and aligned to either the A Train or the B Train Control Building Air Conditioning System fan unit. During normal plant operation, with the non -safety subsystem aligned for Control Room cooling on the A Train fan unit, the control switch on the MCB for the safety related train will be aligned for AUTO operation. On a loss of offsite power, the non -safety chilled water subsystem will be shut down and an automatic start sequence will be initiated via the emergency diesel generator load sequencer to restart the AC unit and start the A Train safety chiller. In the event the A Train of the CBA fails to start, operator actions, prompted by high Control Room temperature, are assumed to secure the failed chiller and associated equipment and start the B Train. All controls for the recovery are in the Control Room. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-90 6. Emergency Feedwater Pump Control Valves FW -FV-4214A, FW -FV-4224A, FW-FV-4234A, FW -FV-4244A These valves are normally open and at least two valves must remain open for safe shutdown. Spurious closure of one valve will not prevent safe shutdown. The operators will prevent further spurious operations by disabling the power supplies to the unaffected valves in the Train A switchgear room (Fire Area: CB -F-1A-A). The safe shutdown requirements are satisfied.

7. Pressurizer Power Operated Relief Valve (PORV) RC

-PCV-456A A cable for RC -PCV-456A is routed in this area. Failure of this cable cannot cause the PORV to spuriously open, so the RCS pressure boundary is maintained.

2. Main Control Room Cooling Equipment CBA

-E-230A, CBA -E-230B, CBA-DP-26A, CBA-DP-26B, CBA-FN-14A, CBA-FN-14B, CBA-FN-211A, CBA-FN-211B, CBA -PDS-21206A1/A2, CBA -PDS-21206B1/B2, CBA-TCV-21200A, CBA -TCV-21200B The control building Train B mechanical room - south is a Class 1 area which for safe shutdown has a primary function of providing protection for the Train B air handling equipment for the Train B switchgear rooms and battery rooms. The area is approximately 26 ft. long by 43 ft. wide by 23 ft. high with floor area of 1120 sq. ft. and volume of 25,800 cu. ft. The in situ combustibles consist of cables in trays.

There are a total of three cable trays which run horizontally through the area. When stacked, the trays run three high with the bottom tray being an enclosed instrument tray. There is approximately 200 ft. of uncovered cable tray containing a total of approximately 50 cables. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-93 Detectors are provided throughout the area. The cable for the Train A cooling equipment is routed in a conduit and box with a one-hour, fire -rated barrier. The only exception is at an interference with two HVAC duct hangers where the one -hour wrap is butted up to the hangers and pyrocrete is installed for heat transfer protection. The conduit and box are approximately 20 ft. above the floor. There are a total of eight cables in tray within 20 ft. horizontal of the barriered conduit. The redundant Train B cables are routed in tray a minimum of 25 ft. from the barriered conduit. The spatial separation, the height above the floor, the routing of one train of cables in conduit with a one -hour, fire -rated barrier and considering the limited in situ combustibles provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III.G.2.c "in addition to 1 hour fire barrier, and automatic fire suppression system shall be installed", has been approved. 2a. Control Room Air Conditioning The non-safety related chilled water system, which is powered from a non -safety related power supply, is normally running and aligned to either the A Train or the B Train Control Building Air Conditioning System fan unit. During normal plant operation, with the non -safety subsystem aligned for Control Room cooling on the B Train fan unit, the control switch on the MCB for the safety related train will be aligned for AUTO operation. On a loss of offsite power, the non -safety chilled water subsystem will be shut down and an automatic start sequence will be initiated via the emergency diesel generator load sequencer to restart the AC unit and start the B Train safety chiller. In the event the B Train of the CBA fails to start, operator actions, prompted by high Control Room temperature, are assumed to secure the failed chiller and associated equipment and start the A Train. All controls for the recovery are in the Control Room. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-94 3. Process Protection Cabinet MM -CP-13 The power cable for the PPC cabinet MM -CP-13 is routed through this fire area. The loss of power to this cabinet will prevent opening of valves RC -V22 and RC-V87. These valves are required to be opened for cooldown below 350F when the RH System is placed in operation. Should the cable damage be such that valves cannot be operated from the MCR, the affected portion of the circuit can be isolated at the RSS panel in the Train B switchgear room (Fire Area: CB-F-1B-A) and the valves repositioned for safe shutdown. The safe shutdown requirements are satisfied.

4. Process Control Cabinet MM

-CP-297B The power cable for PCC cabinet MM -CP-297B is routed through this fire area. The loss of power to this cabinet will result in loss of CST level transmitter FW-LT-4257 and emergency feedwater flow transmitters FW -FT-4224-2 and FW-FT-4244-2. The Train A CST level transmitter FW -LT-4252 is not affected by a fire in this area. Additionally, the emergency feedwater flow to two steam generators will be available along with steam generator level for all four steam generators. The Appendix R separation requirements are satisfied.

5. Reactor Vent Valve RC

-FV-2881 A cable for the normally closed, fail closed valve RC -FV-2881 is routed through this fire area. The spurious opening of this valve will not prevent safe shutdown as functionally redundant valve RC -V323 is normally closed and has no cables, controls, or equipment in this fire area so it cannot spuriously open. The Appendix R separation requirements are satisfied.

6. Emergency Feedwater Pump Control Valves FW

-FV-4214B, FW -FV-4224B, FW-FV-4234B, FW -FV-4244B These valves are normally open and at least two valves must remain open for safe shutdown.

Analysis 1. General Area Analysis

a. Mechanical Penetration Area (PP

-F-XX-Z) The mechanical penetration area is a Class 1 concrete structure which for safe shutdown has a primary purpose of protecting the containment isolation valves for component cooling, charging pumps and RHR. The area is sectioned into compartments, separated by concrete walls, with small openings for access. This configuration would most probably limit a fire caused by transient combustibles to one zone in the area. The area contains no in situ combustibles with the exception of cable in trays. Only Train A safe shutdown cables are routed in trays. All Train B safe shutdown cables are in conduits. Personnel access to the radioactive areas will be limited to operator tours. Detectors are provided throughout the area.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-104 b. Containment Fan Enclosure Area and Containment Annulus (CE -F-l-Z) The containment fan enclosure area is a Class 1 concrete structure which for safe shutdown has a primary function of providing protection for the redundant cooling and air handling equipment for the RHR, CBS, SI equipment vaults; the charging pump rooms; and the mechanical penetration area. The area is approximately 112 feet long by 21 feet wide by 29'-6" high with a floor area of 3000 sq. ft. and volume of 90,000 cu. ft. The in situ combustibles consist of cables in trays and charcoal in filters and fiberglass ladders. There are a total of seven cable trays which are stacked four high for the Train A trays and three high for the Train B trays. The bottom tray in each stack is an enclosed instrumentation cable tray. The trays are a minimum of 13'-6" above the floor. There is approximately 275 lineal ft. of uncovered cable tray containing a total of 80 cables. With the exception of three cables, the Train B cables for the fans are routed in one -hour, fire-rated barriered conduits from the point where they enter the area to the equipment. The charcoal filters which contain 1050 lbs. of charcoal each are not required for safe shutdown nor are they within 30 ft. of the cooling units. The units have an early fire detection system internal to the units. Detectors are provided throughout the area.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-105 2. System/Equipment Analysis

a. Component Cooling Isolation Valves CC

-V175, CC-V257, CC-V122, CC-V168 The redundant component cooling containment isolation valves CC -V175, CC-V257, CC-V122 and CC -V168 are located in proximity. These valves are normally open and remain open for safe shutdown. The valves are provided with dual coil solenoids that must be energized to close the valves. The operators can prevent spurious operation by tripping the power supply breakers at the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). It should be noted, however, that these valves are required to remain operable only for containment entry when manual operation of the safety injection isolation valves SI -V3, SI-V17, SI-V32 and SI -V47 and the reactor coolant - RHR isolation valves RC-V22, RC-V23, RC-V87 and RC -V88 is required. Cables for these valves are not routed through this fire area; hence the valves would be operable from the main control room or the RSS control panels and containment entry would not be required. The safe shutdown requirements are satisfied.

b. Thermal Barrier Containment Isolation Valves CC

-V1101, CC -V1109, CC-V1092, CC -V1095 The redundant thermal barrier containment isolation valves CC -V1101, CC-V1109, CC -V1092, CC -V1095 are located in the same fire area. The redundant valves are in separate fire zones separated by a concrete wall. These valves are normally open and remain open for safe shutdown. The operators will prevent spurious operation of more than one valve by tripping the power supply breakers for these valves at the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-106 c. Charging Line Isolation Valves CS -V142, CS-V143 The redundant charging line isolation valves CS -V142 and CS -V143 are located in the same fire area. These valves are normally open and at least one valve is required to be closed for safe shutdown. The functionally redundant valve CS -HCV-182 is not located in this fire area; hence, it can be closed to isolate the normal charging line. The Appendix R separation requirements are satisfied.

d. Seal Injection Isolation Valves: CS

-V154, CS-V158, CS-V162, CS-V166 and High Head Injection Valves SI -V138, SI-V139 Under normal conditions, the seal injection isolation valves CS -V154, CS-V158, CS-V162 and CS -V166 are utilized for the seal injection flow path. Spurious closure of one of these valves will not prevent safe shutdown. The operators will prevent further spurious operations by tripping the power supply breakers in the Train A switchgear room (Fire Area: CB-F-1A-A). The high head injection valves SI -V138 and SI -V139 are normally closed valves which may be opened to provide a redundant hot standby charging path. If the seal injection path is available, the position of these valves during hot standby is inconsequential. On cooldown, the operators will either close or maintain closed the high head injection path. If the high head injection path cannot be isolated, a capability is provided to manually align and throttle the charging pumps to the seal injection flow paths. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-107 e. RC Pump Seal Water Isolation Valve CS -V167 Valve CS-V167 is a normally open valve that should remain open for safe shutdown. Spurious isolation of the Train A valve could result in loss of inventory through the upstream relief valve. This inventory is directed to the PRT and is, therefore, non -recoverable. To preclude this loss of inventory, functionally redundant isolation capability is provided by the RC pump seal return lines by means of Train A valves CS -V10, CS-V28, CS-V44 and CS -V59 and the excess letdown line by means of normally closed, fail closed valves CS -V175 or CS -V176. The cables, controls and equipment required for operation of valves CS -V10, CS-V28, CS-V44, CS-V59, CS-V175 and CS -V176 are not contained in this fire area. The Appendix R separation requirements are satisfied.

f. Containment Enclosure Cooling Units EAH

-AC-2A, EAH-AC-2B; Fans EAH-FN-5A, EAH-FN-5B; Dampers EAH -DP-3A, EAH-DP-3B and Terminal Boxes EDE -TBX-YC3, EDE-TBX-YB3 The redundant cooling units EAH -AC-2A and EAH -AC-2B are totally enclosed fiberglass insulated steel units which house the motor, fan and cooling coils. The units are separated by 8 ft. of clear space and the fan motors EAH -FN-5A and EAH -FN-5B are approximately 25 ft. apart. During normal operation only one cooling unit is required to operate. An analysis has shown that a worst case fire caused by burning five (5) gallons of heptane between the cooling units can affect potentially one cooling unit. All Train B cables required for operation of the cooling unit EAH -AC-2B are routed in one -hour, fire -rated barriered conduits from the rated fire wall where they enter the fire area to the equipment. The spatial separation, the routing of one train of cables in a conduit with a one-hour, fire -rated barrier, the limited in situ combustibles provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-108 g. Containment Enclosure Return Fans EAH -FN-31A, EAH-FN-31B and Dampers EAH -DP-25A and EAH -DP-25B. The redundant return fans EAH -FN-31A and EAH -FN-31B are located 20 ft. above the floor and are an integral part of the HVAC ducts (one in each duct). These fans are required to maintain the equipment vaults habitable for entry if manual operations are required to place RHR into operation for cold shutdown. A fire in the containment enclosure fire zone CE -F-1-Z will not prevent operation from the MCR of any equipment necessary for RHR operation; hence, habitability of the equipment vaults is not required. Analysis and field testing has confirmed that the containment enclosure supply fan EAH -FN-5A or EAH -FN-5B is sufficient to maintain the equipment vaults below the equipment 's qualified temperatures. The safe shutdown requirements are satisfied.

h. Containment Enclosure Isolation Damper, PAH

-DP-35B, PAH-DP-36B Cables for dampers PAH -DP-35B and PAH -DP-36B are routed through this area. Under normal operation both dampers are open. If both dampers go closed, the Containment Enclosure Air Handling (EAH) system operates in the recirculation mode. The normal and recirculation modes for EAH system operation both satisfy the safe shutdown function. Independent operation of either damper (one open and one closed) could cause an air flow problem in EAH system. This assumes that both redundant dampers (PAH -DP-35A and PAH -DP-36A) are in their normal open position since they would not be affected by a fire in this area. Both dampers are powered from a single Train B power supply. The circuit design is such that a spurious signal will cause both dampers to operate together, either both open (normal mode) or both closed (recirculation mode). The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-109 i. RHR Isolation Valves RC -V22, RC-V23, RC-V87, RC-V88 and Sample Valves RC -FV-2894, RC-FV-2896 Redundant cables associated with the position indicating lights for the RHR isolation valves are contained in this area. Failure of these circuits will not prevent the operators from opening the valves for entry into cold shutdown. Although this indication is desirable, other means are available to confirm RH system operability (e.g. RH Pump Flow). The safe shutdown requirements are satisfied.

j. H Pump to Cold Leg Isolation Valves RH

-V14, RH-V26 Valves RH -V14 and RH -V26 are normally open valves which are required to remain open for RH systems operation (cold shutdown). These valves and their related cables are in proximity. If either valve spuriously closes, the operators will prevent further spurious operation of the redundant valve by tripping the power supply breakers in either the Train A or Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The safe shutdown requirements are satisfied.

k. RH Pump to Hot Leg Isolation Valves RH

-V70, RH-V32 Valves RH -V70 and RH -V32 are normally closed valves which are required to remain closed for RH system operation (cold shutdown). These valves and their related cables are in proximity. If either valve spuriously opens, the operators will prevent further spurious operation of the redundant valve by tripping the power supply breakers in either the Train A or Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-110 l. RH Heat Exchanger to CS/SI Pump Isolation Valves RH-V35, RH-V36, Containment Sump Isolation Valves CBS -V8, CBS-V14 and Terminal Boxes EDE -TBX-Y32, EDE-TBX-Y35 Cables for the redundant valves RH -V35 and RH -V36 are routed in proximity to one another. Valves RH -V35 and RH -V36 are normally closed and their position is inconsequential during all modes of plant operation with the exception of cooldown below 350F when the RH system is placed in operation. At that time it is necessary to assure that the valves remain closed. Should one of the valves open spuriously the operators can disable its power supply in either the Train A or Train B switchgear rooms (Fire Areas: CB -F-1A-A or CB-F-1B-A) and manually reposition the valves located in the equipment vaults (Fire Zone RHR-F-4B-Z or RHR-F-2-A-Z). Manual operation of the valves can be delayed as much as 9 hours into the event. Therefore, no fire protection other than the existing separation is needed. The provision of a capability to mitigate the spurious operation of the valves outside the fire area satisfies the safe shutdown requirements.

m. Containment Pressure Transmitters SI

-PT-936, SI-PT-937 Redundant channels of containment pressure instruments and cables are located in proximity. Spurious operation of these channels will initiate containment spray and containment isolation Phase B. The operators will have the capability to terminate these protective actions by use of manual reset switches. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CB -1F-1A-A and CB-F-1B-A). The provision of a capability to mitigate the spurious operation of the pressure transmitters outside the fire area satisfies the safe shutdown requirements.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-111 C. Evaluation Deviations from the Appendix R, Paragraph III.G.2 separation requirements exist in the containment fan enclosure area and the mechanical penetration area, and have been discussed and analyzed above. A deviation for Appendix R, Paragraph III G.2c, "in addition to a 1 hour fire barrier, an automatic fire suppression system shall be installed ", has been approved. These deviations are justified based on the analysis and our assertion that additional modifications would not enhance fire protection safety.

Analysis Redundant equipment and cables are located in the same fire area. The plant will normally be operating on service water pumps SW -P-41A, B, C, and D. These pumps are located in the service water pump house which is a separate area (Fire Area: SW -F-1E-Z). SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-119 This area contains valves SW -V25 and SW -V54 which are normally closed. The spurious opening of SW -V25 would divert B Train service water flow to the cooling tower thus reducing cooling flow to the diesel generator and PCCW heat exchangers. Spurious opening of SW -V54 would result in the same condition for the A Train service water system. The operators will prevent further spurious operation of the redundant valve by tripping the power supply breakers for EDE -MCC-513 at the 480 Volt Unit Substation E51 (Fire Area: CB -F-1A-A) for SW -V54 and the EDE -US-64 supply breaker at 4160 Switchgear E6 (Fire Area: CB -F-1B-A) for valve SW -V25. Thus, one train of service water capability is assured. Permissive logic for redundant SW pumps could prevent the redundant SW pumps from being started (Note: one pump of each Train is normally running). The operators will prevent spurious operation of the permissive logic by tripping the power supply breakers at the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). This area contains cooling tower fan SW -F-51A, pump SW -P110A, valves SW -V54, SW-V55, SW-V56, SW-V139, fans SWA -FN-64, SWA-FN-71, damper SWA -DP-66 and switch SWA -TSH-5667. The cooling towers are considered a redundant capability which may be utilized for a limited period of time during the year (e.g., tunnel heat treating). Should a fire occur during this time period the operators can utilize the Train B service water pumphouse capability. The cables, controls and equipment required for the Train B service water pumphouse capability are not contained in this fire area. C. Evaluation The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-127 2. Component Cooling Water Pumps CC -P-11B, CC-P-11D and Component Cooling Water Containment Isolation Valves CC -V122, CC-V168 A fire could cause loss of all PCCW to Containment. It should be noted, however, that these valves are required to remain operable only for containment entry when manual operation of the safety injection isolation valves SI -V3, SI-V17, SI-V32 and SI -V47 and the reactor coolant - RHR isolation valves RC-V22, RC-V23, RC-V87 and RC -V88 are required. Cables for these valves are not routed through this fire area; hence, the valves would be operable from the main control room or the RSS control panels and containment entry would not be required. The safe shutdown requirements are satisfied.

3. RHR Isolation Valves RC

-V22, RC-V87 Redundant cables associated with the position indicating lights for the RH R isolation valves are contained in this area. Failure of these circuits will not prevent the operators from opening the valves for entry into cold shutdown. Although this indication is desirable, other means are available to confirm RH System operability (e.g. RH Pump Flow). The safe shutdown requirements are satisfied.

4. Volume Control Tank Isolation Valve CS

-LCV-112C and Charging Pump CS-P-2A & CS-P-2B Volume control tank (VCT) isolation valves CS -LCV-112B & -112C are normally open to provide a suction path from the VCT to the normally operating charging pump (CS -P-2A or -2B). These valves must stay open until RWST valve CS-LCV-112D or -112E is manually opened to provide a charging pump suction path from the RWST, or the boric acid tanks are manually aligned as a charging pump suction source. Spurious closure of a VCT isolation valve caused by a hot short would interrupt suction flow to the operating charging pump causing it to be damaged. If the standby charging pump has cables in the same area then its operation can also be prevented. The result would be no charging system flow. Since this fire area contains cables for CS -LCV-112C and CS -P-2B, this condition is potentially applicable for the system alignment with CS -P-2B the standby pump and CS -P-2A the operating pump.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-128 The CS-LCV-112C circuit design prevents spurious valve closure from hot shorts as follows. The field cable conductors for the motor control center (MCC) contactor close coil circuit are in different cables than the 120 V "hot" circuit conductors eliminating the hot short failure mode within the cables. Cable-to-cable hot shorts need not be postulated for thermoset cable insulation as used at Seabrook. Since CS -LCV-112C will not spuriously close, CS -P-2A as the operating charging pump will not be damaged. Also, the CS -LCV-112C and CS-P-2B cables are routed in separate concrete encased conduits within the duct bank so that one fire can not damage both the valve and the standby pump cables. Since charging flow is available, the safe shutdown requirements are satisfied. C. Evaluation The safe shutdown requirements and Appendix R separation requirements are satisfied.

Process Protection Cabinet MM -CP-12 The power cables for the PPC cabinet MM -CP-12 is routed through this fire area. The loss of power to this cabinet will prevent opening of valves RC -V23 and RC-V88. Valve RC -V88 is required to be opened for cooldown below 350F when the RH system is placed in operation. Should the cable damage be such that valves cannot be operated from the MCR, the affected portion of the circuit can be isolated at the RSS panel in the Train A switchgear room (Fire Area: CB -F-1A-A) and the valves repositioned for safe shutdown. The safe shutdown requirements are satisfied.

3. Process Control Cabinet MM

-CP-297A The power cable for PCC cabinet MM -CP-297A is routed through this fire area. The loss of power to this cabinet will result in loss of CST level transmitter FW-LT-4252 and emergency feedwater flow transmitters FW -FT-4214-2 and, FW-FT-4234-2. The Train B CST level transmitter FW -LT-4257 is not affected by a fire in this area. Additionally, the emergency feedwater flow to two steam generators will be available along with steam generator level for all four steam generators. The Appendix R separation requirements are satisfied.

4. Normal Letdown Isolation Valve RC

-LCV-459 Cables for valve RC -LC-459 are routed in this fire area. The cables, controls, and equipment for functionally redundant valve CS -V145 are not contained in this area and; hence, will be available for safe shutdown. The Appendix R separation requirements are satisfied.

Pressurizer Power Operated Relief Valve RC -PCV-456A RC-PCV-456A is a normally closed, fail closed valve whose cables are in this fire area. The spurious opening of a PORV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. The PORV is supplemented with a normally open, series block valve RC -V122. For all fires that have the potential to cause spurious opening of the PORV, the operators will close the block valve by procedure. This will be the first step in the procedure and can readily be accomplished from the main control room. The promptness of this action is justification for the ability to isolate the block valve prior to any spurious valve operations. Under the condition, the initial short will not cause depressurization. To prevent subsequent spurious operations, the operators will de -energize the PORV by tripping its power supply in the Train A switchgear room (Fire Area: CB -F-1A-A). The safe shutdown requirements are satisfied.

6. Control Room Air Conditioning The non-safety related chilled water system, which is powered from a non

-safety related power supply, is normally running and aligned to either the A Train or the B Train Control Building Air Conditioning System fan unit. During normal plant operation, with the non-safety subsystem aligned for Control Room cooling on the A Train fan unit, the control switch on the MCB for the safety related train will be aligned for AUTO operation. On a loss of offsite power, the non -safety chilled water subsystem will be shut down and an automatic start sequence will be initiated via the emergency diesel generator load sequencer to restart the AC unit and start the A Train safety chiller. In the event the A Train of the CBA fails to start, operator actions, prompted by high Control Room temperature, are assumed to secure the failed chiller and associated equipment and start the B Train. All controls for the recovery are in the Control Room. The safe shutdown requirements are satisfied.

Analysis 1. General Area Analysis The diesel generator mechanical equipment room is a Class 1 area which for safe shutdown has a primary function of providing protection for the redundant air handling equipment for the diesel generator rooms. The area is approximately 86 ft long by 37 ft. wide by 26 ft. high with a floor area of 3200 sq. ft. and volume of 83,000 cu. ft. The in situ combustibles consist of cables in trays, 7 gallons of oil in equipment, and fiberglass ladders. There are a total of six cable trays which run horizontally and vertically through the area. When stacked the trays are run three high with the bottom tray being an enclosed instrumentation cable tray. There is approximately 375 ft. of uncovered cable tray containing a total of approximately 80 cables. Detectors are provided throughout the area. An analysis has shown that a worst case fire caused by burning 3.5 gallons of oil will not affect the operation of the Safe Shutdown equipment.

2. System/Equipment Analysis

a. Main Control Room Cooling CBA

-E-230A, CBA -E-230B, CBA-FN-211A, CBA -FN-211B, CBA -P-434A, CBA -P-435A, CBA-P-434B, CBA -P-435B, CBA -PDS-21202A, CBA -PDS-21202B, CBA-PDS-21206A1/A2, CBA -PDS-21206B1/B2 The redundant control room cooling equipment and cables are located in the same fire area. A fire in this area can cause total loss of this cooling capability. Should this occur, the operators will utilize the evaporator fans CBA-FN-14A, 14B to supply outside air into the control room. These fans and their cables are not in this fire area. An air inlet and exhaust path, utilizing these fans, can be established by opening certain doors in the control room complex which will allow air to enter into the fan intake plenum from the south stairwell and exhaust the control room via the double doors to the turbine building. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-148 b. Diesel Generator Room Cooling DAH-FN-25A, DAH-FN-25B, DAH-FISH-5529, DAH -FISH-5530 The Safe Shutdown cables for the fans and flow switches are routed in barriered conduit from the floor where they enter the area to the equipment (a distance of approximately 20 feet or less). The one -hour, fire -rated barrier is reduced at two locations or stops approximately two feet from the equipment because of access or potential interference. The redundant fans and dampers are separated by approximately 28 feet with the only intervening combustible being approximately 44 cables in three vertical/horizontal Train B trays and approximately 33 cables in two horizontal Train A trays. The Train A and Train B trays are separated by 8 ft. The redundant flow switches and associated conduits are separated by 45 ft. with the above trays containing the only intervening combustibles. The spatial separation, the routing of both trains of cables in separate conduits with a one -hour, fire -rated barrier and the limited in situ combustibles provide acceptable fire protection equivalent to the technical requirements of Appendix R. Note: A deviation was requested and granted for not installing suppression in this location. Since that deviation was granted the following conservative changes have been made, the electrically operated supply dampers have been changed to back draft dampers and the supply fan flow switch interlock with the exhaust fan has been removed. Cables for the flow switch are still routed in barriered conduit because their failure could effect the control circuit for the supply fan. These changes do not adversely effect the basis of the deviation.

c. Diesel Generator Control DG

-CP-76A, DG-DG-1B, EDE-SWG-6 The cables for control panels DG -CP-76A and DG -DG-1B are located in this area. Failure of these cables will render the Train B diesel inoperable from the main control room. The operators can re -establish Train B diesel operability by transferring control to the RSS panel located in the Train B diesel room (Fire Area: DG -F-2B-A). Operation of the diesel from the RSS panel will also allow re -establishing emergency power to EDE-SWG-6 by isolation of the faulted main control room cables. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-149 d. Process Protection Cabinet MM -CP-13 The power cable for the PPC cabinet MM -CP-13 is routed through this fire area. The loss of power to this cabinet will prevent opening of valves RC-V22 and RC -V87. These valves are required to be opened for cooldown below 350F when the RH system is placed in operation. Should the cable damage be such that valves cannot be operated from the MCR, the affected portion of the circuit can be isolated at the RSS panel in the Train B switchgear room (Fire Area: CB -F-1B-A) and the valves repositioned for safe shutdown. The safe shutdown requirements are satisfied.

e. Normal Letdown Isolation Valve RC

-LCV-459 Cables for valve RC -LCV-459 are routed in this fire area. The cables, controls and equipment for functionally redundant valve CS -V145 are not contained in this area and; hence, will be available for safe shutdow

n. The Appendix R separation requirements are satisfied.

f. Reactor Vent Valve RC

-FV-2881 A cable for the normally closed, fail closed valve RC -FV-2881 is routed through this fire area. The spurious opening of this valve will not prevent safe shutdown as functionally redundant valve RC -V323 is normally closed and has no cables, controls, or equipment in this fire area so it cannot spuriously open. The Appendix R separation requirements are satisfied. C. Evaluation Deviations from the Appendix R, Paragraph III.G.2 separation requirements exist in the diesel generator building El. 51 '-6" for the DAH system and have been discussed and analyzed above. A deviation from Appendix R, Paragraph III G.2c, "in addition to 1 hour fire barrier, an automatic fire suppression system shall be installed ", has been approved. These deviations are justified based on the analysis and our assertion that additional modifications would not enhance fire protection safety. For the remainder of the systems affected in this analysis, the safe shutdown requirements and the Appendix R separation requirements are satisfied.

Analysis The emergency feedwater pump building is a Class 1 concrete structure which for Safe Shutdown has a primary function of providing protection for the motor driven feedwater pump and valves. The area is approximately 79 ft. long by 28 ft. wide by 18 ft. high with a floor area of 2400 sq. ft. and a volume of 43,000 cu. ft.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-157 The in situ combustibles consist of six gallons of oil in the turbine drive of emergency feedwater pump FW -P-37A and 27 pounds of plastic in a 10 ft. step and 24 ft. extension ladder. An analysis of the Design basis Fire for this combustible is contained in the "Fire Protection Program Evaluation and Comparison to Branch Technical Position APCSB-9.5-1 Appendix A. All cables are routed in conduit. Detectors are provided throughout the area.

See Section 3.4 for a discussion of the operator response for a fire in this area.

The eight emergency feed pump control valves are separated such that valves FW-FV-4214A, B and FW-FV-4244A, B are separated by 60 feet from valves FW-FV-4224A, B and FW -FV-4234A, B. See Section 3.4 for more discussion of these valves. The redundant fans and dampers are in separate steel enclosures located 11 ft. above the floor, and separated b y 1'-6". The temperature switches are separated by over 20 '. The redundant CST Level transmitters FW -LT-4252 and FW -LT-4257 are separated by 16'. The motor driven emergency feedwater pump and recirculation valve FW -V347 are located in this fire area. For a fire in this area, the start -up feedwater pump FW -P-113 (SUFP) and start -up to EFW valves FW -V156 and FW -V163 will be utilized to satisfy the safe shutdown requirements. The SUFP low suction pressure trip must also be bypassed prior to commencing cooldown. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-158 During no -load and low load plant operations, the SUFP is aligned to non -emergency Bus 4 to provide its startup and shutdown functions. After the SUFP completes its startup function, its power supply will be transferred to emergency Bus E5 as plant power is increased. The SUFP will remain aligned to Bus E5 during 100% power operation. As power is decreased in preparation for a plant shutdown, the SUFP power supply will be transferred back to Bus

If the SUFP is required to perform its EFW contingency function in response to a fire that disables the Train B emergency feedwater pump, while aligned to Bus 4 coincident with a loss of offsite power, it will have to be manually transferred to Bus E5 and manually started. SUFP operation will be controlled by operating procedures including selection of the appropriate power supply and verification of adequate power supply capacity prior to starting the SUFP on the emergency diesel generator.

The main control room would not have to be evacuated for a fire in this area; hence, the operators would have the capability to control and monitor all the equipment which is powered from the electrical distribution emergency system and would be required for a safe shutdown. Additional details on the alternative safe shutdown capability are contained in Section 3.4. C. Evaluation A deviation from the requirements of Appendix R, Paragraph III.G.3 requiring the installation of fixed suppression in an area for which alternative safe shutdown capability has been developed exists in the emergency feedwater pump building. This deviation is justified based on our assertion that additional modifications would not enhance plant safety which has been insured by the alternative shutdown capability discussed in Section 3.4 and Tabulation 3.4.3.

Analysis 1. General System/Equipment Analysis With the exception of the systems/equipment discussed below, a fire in this area will only affect the Train A safe shutdown equipment and cables. The redundant Train B safe shutdown equipment and cables are located in fire area ET -F-1C-A. The Appendix R safe shutdown requirements are satisfied.

2. Component Cooling Water Isolation Valves CC

-V57, CC-V121, and Head Tank Level Transmitters CC -LT-2172-1, 2, 3, CC -LT-2272-1, 2, 3 Cables associated with head tank level transmitters which affect the Loop B outboard isolation valves CC -V175 and CC -V257 are routed in the same trays as the Loop A inboard isolation valves CC -V57 and CC -V121. Failures in these cables could cause total loss of PCCW to containment by initiation of a spurious

lo-lo head tank level signal. Loop B PCCW can be re -established by transferring control of valves CC -V175 and CC -V257 to local control at the RSS panel in fire area CB-F-1A-A. This removes the lo -lo head tank level isolation function and allows operators to re -open the valves. The safe shutdown requirements are satisfied.

3. RC Pump Seal Water Isolation Valves CS

-V10, CS-V28, CS-V44, CS-V59 The safe shutdown function of these valves is to isolate seal return in the event that valve CS -V168 spuriously closes due to a fire. As cabling for CS-V168 is not routed through this area, the position of these valves is inconsequential and will not prevent safe shutdown. The safe shutdown requirements are satisfied.

4. Letdown Isolation Valves CS

-V145, RC-LCV-459, RC-LCV-460 Functionally redundant Train A series valves CS -V145, RC-LCV-459 and RC-LCV-460 are normally open and are required to close for safe shutdown. CS-V145 can be closed from the main control room. Should this valve not close due to spurious operation, the operators can close either RC-LCV-459 or RC-LCV-460 by tripping their power supply breakers at the Train A switchgear room (Fire Area: CB -F-1A-A). This will prevent further spurious operation. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-164 5. Charging Pump Test Line Isolation Valve SI-V159 On spurious operation of the normally closed, fail closed valve SI -V159 (Train A), the operators will maintain the normally closed high head injection path valves SI -V138 and SI -V139 closed. Charging will be accomplished utilizing the seal injection flow path through valves CS -FCV-121, CS-V154, CS-V158, CS-V162 and CS -V166. The cables, controls and equipment required for operation of these valves are not contained in the fire area. The capability to provide charging to the RC System through a minimum of one flow path satisfies the safe shutdown requirements.

6. RHR Isolation Valves RC

-V23, RC-V88 RHR isolation valves are permanently disabled in the closed position. For entry into RHR shutdown cooling, valve RC -V88 must be opened. These valves are not required until 9 hours into the event. This can be accomplished manually by entry into containment, if required. The safe shutdown requirements are satisfied.

7. Emergency Feedwater Pump Control Valves FW

-FV-4214A, FW -FV-4224A, FW-FV-4234A, FW-FV-4244A These valves are normally open and at least two valves must remain open for safe shutdown. Spurious closure of one valve will not prevent safe shutdown. The operators will prevent further spurious operations by disabling the power supplies to the unaffected valves in the Train A switchgear room (Fire Area: CB -F-1A-A). The safe shutdown requirements are satisfied.

8. Main Steam Isolation Valves MS

-V86, MS-V88, MS-V90, MS-V92 Failure of the Train A cables will not prevent safe shutdown as the redundant Train B cables required for MSIV closure are routed in Fire Area ET -F-1C-A. The Appendix R separation requirements are satisfied.

9. Not used SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-165 10. Atmospheric Relief Valves MS

-PV-3002, MS-PV-3003 and Associated Solenoids Valves MS -PV-3002 and MS -PV-3003 are normally closed valves. A fire would prevent operation of the Train A capabilities provided for opening and closing these valves. However, the fire would not affect the Train B capabilities and the valves will be operable for safe shutdown. Spurious opening of even one ARV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. Since the ARV 's are air operated valves, their spurious operation will be prevented by assuring that these valves are placed in a state such that the initial spurious operation in the air supply will not cause the valve to open. This will be accomplished by procedure as one of the first steps for any fire that can affect the integral ARV air system cables. This action is justifiable since it can be accomplished from the main control room. To prevent a subsequent short that could override the initial action and cause the ARV to open, the affected air solenoids will be de -energized from the distribution panels located in Train A switchgear room (Fire Area: CB -F-1A-A). This will isolate the faulted air supply but will not preclude operation of the ARV since the redundant air solenoids will still be operational. The safe shutdown requirements are satisfied.

11. Tower Actuation Logic Pressure Transmitters SW

-PT-8272, SW-PT-8273, SW-PT-8274 Failure in this cable could initiate a spurious tower actuation signal which would transfer Train A service water cooling capability from the pumphouse to the cooling towers. This transfer will not significantly interrupt Train A service Water cooling nor will it have any impact on Train B service water. This failure does not prevent safe shutdown. The safe shutdown requirements are satisfied.

Main Steam Pressure Transmitters FW -PT-524, FW-PT-526, FW-PT-534, FW-PT-536 Redundant channels of main steam pressure cables are located in proximity. Spurious operation of the channels will initiate safety injection and containment isolation Phase A signals. The operators will have the capability to terminate SI after 1 minute by use of the manual reset block switch and terminate the containment isolation by use of the manual reset switch. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CS -F-1A-A and CB-F-1B-A). The safe shutdown requirements are satisfied.

13. Steam Generator Level Transmitters FW

-LT-501, FW-LT-503, FW-LT-529, FW-LT-548 Cables for transmitters FW -LT-501, FW-LT-503, FW-LT-529, FW-LT-548 are located in the same fire area. A Fire could cause loss of indication for all four steam generators. However, the same fire would not affect the redundant level transmitters FW -LT-502, FW-LT-504, FW-LT-519 and FW -LT-537. The Appendix R separation requirements are satisfied.

14. Emergency Feedwater Flow Transmitters FW

-FT-4214-2, FW-FT-4224-4, FW-FT-4234-2, FW-FT-4244-4 Failure in this cable could cause spurious closure of one emergency feedwater line. The logic will prevent isolation of additional lines. This leaves three steam generators available for heat removal; hence, safe shutdown is not affected. Although, failure in this cable could also cause loss of flow indication on two emergency feedwater lines, steam generator operability can be monitored by use of SG level indication. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-167 15. Condensate Storage Tank Level FW-LT-4252 All cables are Train A. The Train B level transmitter FW -LT-4257 will be available. In addition, the cables for CST level transmitter CO -LT-4096 are not routed through this area. The safe shutdown requirements are satisfied.

16. Pressurizer Pressure Transmitters RC

-PT-455, RC-PT-457 Redundant channels of pressurizer pressure cables are located in proximity. Spurious operation of two channels will initiate safety injection and containment isolation Phase A signals. The operators will have the capability to terminate SI after 1 minute by use of the manual reset and block switch and terminate the containment isolation by use of the manual reset switch. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B Switchgear Rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The provision of a capability to mitigate the spurious operation of the pressure transmitters outside the fire area satisfies the safe shutdown requirements.

17. Reactor Coolant Temperature Elements RC

-TE-413A, RC-TE-423A, RC-TE-433A, RC-TE-443A All hot leg RC temperature element cables are routed through this area; however,

this function can also be performed by the Train B incore thermocouples IC-TE-XX. The cables for these thermocouples are routed through the Train B electrical tunnel (Fire Area: ET -F-1C-A). The Appendix R separation requirements are satisfied.

Pressurizer Relief Valves RC -PCV-456A, RC-V122 RC-PCV-456A is a normally closed, fail closed valve whose cables are in this fire area. The spurious opening of a PORV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. The PORV is supplemented with a normally open, series block valve RC -V122. For all fires that have the potential to cause spurious opening of the PORV, the operators will close the block valve by procedure. This will be the first step in the procedure and can readily be accomplished from the main control room. The promptness of this action is justification for the ability to isolate the block valve prior to any spurious valve operations. Under the condition, the initial short will not cause depressurization. To prevent subsequent spurious operations, the operators will de -energize the PORV and the block valve by tripping their power supplies in the Train A switchgear room (Fire Area:

CB-F-1A-A). The safe shutdown requirements are required.

19. Containment Pressure Transmitter SI

-PT-935 A cable for one channel of containment pressure instrumentation is routed through this fire area. This channel inputs to 2 out of 3 and 2 out of 4 logics which initiate protective actions. A spurious signal from one channel is not sufficient to initiate the logic and perform the protective action; hence, a failure in this cable will not prevent safe shutdown. The safe shutdown requirements are satisfied. C. Evaluation The safe shutdown requirements and Appendix R separation requirements are satisfied.

Pressurizer Relief Valves RC -PCV-456A, RC-V122 RC-PCV-456A is normally closed, fail closed valve whose cables are in this fire area. The spurious opening of a PORV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. The PORV is supplemented with a normally open, series block valve RC -V122. For all fires that have the potential to cause spurious opening of the PORV, the operators will close the block valve by procedure. This will be the first step in the procedure and can readily be accomplished from the main control room. The promptness of this action is justification for the ability to isolate the block valve prior to any spurious valve operations. Under the condition, the initial short will not cause depressurization. To prevent subsequent spurious operations, the operators will de -energize the PORV and the block valve by tripping their power supplies in the Train A switchgear room (Fire Area:

CB-F-1A-A). The safe shutdown requirements are satisfied.

21. High Head Safety Injection Valve SI

-V-138 SI-V-138 is a normally closed valve which may be opened to provide a redundant hot standby charging path. The functionally redundant Train B valve SI -V-139 is available to perform this function. Should SI -V-138 spuriously open, the charging pump may have to be stopped to prevent overfill of the pressurizer. The safe shutdown requirements are satisfied. C.

Analysis 1. General System/Equipment Analysis With the exception of the systems/equipment discussed below, a fire in this area will only affect the Train B safe shutdown equipment and cables. The redundant Train A safe shutdown equipment and cables are located in fire area ET -F-1A-A. The Appendix R separation requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-183 2. Component Cooling Water Isolation Valves CC -V176, CC-V256 and Head Tank Level Transmitters CC -LT-2192-1, 2, 3, CC -LT-2292-1, 2, 3 Cables associated with head tank level transmitters which affect the Loop A outboard isolation valves CC -V122 and CC -V168 are routed in the same trays as the Loop B inboard isolation valves CC -V176 and CC -V256. Failures in these cables could cause total loss of PCCW to containment by initiation of a spurious lo-lo heat tank level signal. Loop A PCCW can be re -established by transferring control of valves CC -V122 and CC -V168 to local control at the RSS panel in fire area CB-F-1B-A. This removes the lo -lo head tank level isolation function and allows operators to re -open the valves. The safe shutdown requirements are satisfied.

3. RC Pump Seal Water Isolation Valve CS

-V168 Valve CS-V168 is a normally open valve which should remain open for safe shutdown. Spurious isolation of the Train B valve could result in RC inventory loss through the upstream relief valves. This inventory is directed to the PRT and is therefore, non -recoverable. To preclude this loss of inventory, redundant isolation capability is provided for the RC pump seal return lines by means of Train A valves CS -V10, CS-V28, CS-V44 and CS -V59. The cables, controls and equipment required for the operation of CS -V10, CS-V28, CS-V44 and CS -V59 are not contained in this fire area. The safe shutdown requirements are satisfied.

4. Letdown Isolation Valves CS

-V175, CS-V176 Functionally redundant Train B series valves CS -V175 and CS -V176 are normally closed and remain closed for safe shutdown. The spurious opening of one valve will not prevent safe shutdown. The operators will prevent further spurious operation by tripping the power supply breakers for CS -V175 and CS -V176 at the Train B switchgear room (Fire Area: CB -F-1B-A). The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-184 5. Charging Pump Test Line Isolation Valve SI -V158 On spurious operation of the normally closed, fail closed valve SI -V158 (Train B), the operators will maintain the normally closed high head injection path valves SI-V138 and SI -V139 closed. Charging will be accomplished utilizing the seal injection path through valves CS -FCV-121, CS-V154, CS-V158, CS-V162 and CS-V166. The cables, controls and equipment required for operation of their valves are not contained in the fire area. The capability to provide charging to the RC system through a minimum of one flow path satisfies the safe shutdown requirements.

6. Head Vent Valves RC-FV-2881 and RC

-V323 Functionally redundant Train B series valves RC -FV-2881 and RC -V323 are normally closed and remain closed for safe shutdown. The spurious opening of one valve will not prevent safe shutdown. The operators will prevent further spurious operation by tripping the power supply breakers for RC -FV-2881 and RC-V323 at the Train B switchgear room (Fire Area: CB -F-1B-A). The safe shutdown requirements are satisfied.

7. RHR Isolation Valves RC

-V22, RC-V23, RC-V87, RC-V88 RHR isolation valves are permanently disabled in the closed position. For entry into RHR shutdown cooling, valves RC -V22 and RC -V23 must be opened. This can be accomplished manually by entry into containment, if required. This manual operation can be delayed as much as 9 hours into the event. The safe shutdown requirements are satisfied.

8. Emergency Feedwater Pump Control Valves FW

-FV-4214B, FW -FV-4224B, FW-FV-4234B, FW -FV-4244B These valves are normally open and at least two valves must remain open for safe shutdown. Spurious closure of one valve will not prevent safe shutdown. The operators will prevent further spurious operations by disabling the power supplies to the unaffected valves in the Train B switchgear room (Fire Area: CB -F-1B-A). The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-185 9. Main Steam Isolation Valves MS -V88, MS-V90 Failure of the Train B cables will not prevent safe shutdown as the redundant Train A cables required for MSIV closure are routed in Fire Area ET -F-1A-A. The Appendix R separation requirements are satisfied.

10. Atmospheric Relief Valves MS

-PV-3002, MS-PV-3003 Valves MS -PV-3002 and MS -PV-3003 are normally closed valves. A fire would prevent operation of the Train B capabilities provided for opening and closing these valves. However, the fire would not affect the Train A capabilities and the valves will be operable for safe shutdown. Spurious opening of even one ARV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. Since the ARV 's are air operated valves, their spurious operation will be prevented by assuring that these valves are placed in a state such that the initial spurious operation in the air supply will not cause the valve to open. This will be accomplished by procedure as one of the first steps for any fire that can affect the integral ARV air system cables. This action is justifiable since it can be accomplished from the main control room. To prevent a subsequent short that could override the initial action and cause the ARV to open, the affected air solenoids will be de -energized from the distribution panel located in Train B switchgear room (Fire Area: CB -F-1B-A). This will isolate the faulted air supply but will not preclude operation of the ARV since the redundant air solenoids will still be operational. The safe shutdown requirements are satisfied.

11. Tower Activation Logic Pressure Transmitters SW

-PT-8282, SW-PT-8283, SW-PT-8284 Failure in this cable could initiate a spurious tower actuation signal which would transfer one train of service water cooling capability from the pumphouse to the cooling towers. This transfer will not significantly interrupt Train B service water cooling nor will it have any impact on Train A service water. This failure does not prevent safe shutdown. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-186 12. Main Steam Pressure Transmitters FW -PT-525, FW-PT-535 A cable for one channel of main steam pressure instrumentation is routed through this fire area. This channel inputs to 2 out of 3 logics which initiate protective actions. A spurious signal from the one channel is not sufficient to initiate the logic. Hence, a failure in this cable will not prevent safe shutdown. The safe shutdown requirements are satisfied.

13. Steam Generator Level Transmitters FW

-LT-502, FW-LT-504, FW-LT-519, FW-LT-537 Cables for transmitters FW -LT-502, FW-LT-504, FW-LT-519, FW-LT-537 are located in the same fire area. A fire could cause loss of indication for all four steam generators. However, the same fire would not affect the redundant level transmitters FW -LT-501, FW-LT-503, FW-LT-529 and FW -LT-548. The Appendix R separation requirements are satisfied.

14. Emergency Feedwater Flow Transmitter FW

-FT-4214-4, FW-FT-4224-2, FW-FT-4234-4, FW-FT-4244-2 Failure in this cable could cause spurious closure of one emergency feedwater line. The logic will prevent isolation of additional lines. This leaves three steam generators available for heat removal; hence, safe shutdown is not affected. Although, failure in this cable could also cause loss of flow indication on two emergency feedwater lines, steam generator operability can be monitored by use of SG level indication. The safe shutdown requirements are satisfied.

15. Condensate Storage Tank Level FW

-LT-4257 All cables are Train B. The Train A level transmitter FW -LT-4252 will be available. In addition, the cables for CST level transmitter CO -LT-4096 are not routed through this area.

The Appendix R separation requirements are satisfied. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-187 16. Reactor Pressure RC -PT-403, RC-PT-405 Redundant reactor pressure instruments and cables are contained in this area. This function can also be performed by functionally redundant pressurizer pressure transmitters RC -PT-455 or RC -PT-457 routed through Fire Area ET-F-1A-A. The Appendix R separation requirements are satisfied.

17. Pressurizer Pressure Transmitters RC

-PT-456, RC-PT-458 Redundant channels of pressurizer pressure cables are located in proximity. Spurious operation of two channels will initiate safety injection and containment isolation Phase A signals. The operators will have the capability to terminate SI after 1 minute by use of the manual reset and block switch and terminate the containment isolation by use of the manual reset switch. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The provision of a capability to mitigate the spurious operation of the pressure transmitters outside the fire area satisfies the safe shutdown requirements.

18. Reactor Coolant Temperature RC

-TE-413B, RC-TE-423B, RC-TE-433B, RC-TE-443B All cold leg RC temperature element cables are routed through this area; however, this function can also be performed by the Train A steam generator pressure transmitters FW -PT-514, FW-PT-524, FW-PT-534, FW-PT-544 because cold leg temperature approximated the saturation temperature corresponding to secondary pressure. The cables for these PT 's are routed through fire area ET -F-1A-A. The safe shutdown requirements are satisfied.

Pressurizer Relief Valves RC -PCV-456B, RC-V124 RC-PCV-456B is normally closed, fail closed valve whose cables are in this fire area. The spurious opening of a PORV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. The PORV is supplemented with a normally open, series block valve RC -V124. For all fires that have the potential to cause spurious opening of the PORV, the operators will close the block valve by procedure. This will be the first step in the procedure and can readily be accomplished from the main control room. The promptness of this action is justification for the ability to isolate the block valve prior to any spurious valve operations.

To prevent subsequent spurious operations, the operators will de -energize the PORV and the block valve by tripping their power supplies in Train B switchgear room (Fire Area:

20. Containment Pressure Transmitters SI

-PT-934, SI-PT-935 Redundant channels of containment pressure instruments and cables are located in proximity. Spurious operation of these channels will initiate safety injection, containment spray and containment isolation Phase A and Phase B. The operators will have the capability to terminate the SI after 1 minute by use of manual reset and block switches and terminate the containment spray and containment isolation by use of manual reset switches. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CB -1F-1A-A and CB-F-1B-A). Provision of a capability to mitigate the spurious operation of the pressure transmitters outside the fire area satisfies the safe shutdown requirements. C.

-PT-515, FW-PT-516, FW-PT-525, FW-PT-535, FW-PT-545, FW-PT-546 Redundant channels of main steam pressure cables are located in proximity. Spurious operation of the channels will initiate safety injection and containment isolation Phase A signals. The operators will have the capability to terminate SI after 1 minute by use of the manual reset and block switch and terminate the containment isolation by use of the manual reset switch. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The safe shutdown requirements are satisfied.

14. Emergency Feedwater Flow Transmitters FW

-FT-4214-4, FW-FT-4224-2, FW-FT-4234-4, FW-FT-4244-2 Failure in this cable could cause spurious closure of one emergency feedwater line. The logic will prevent isolation of additional lines. This leaves three steam generators available for heat removal; hence, safe shutdown is not affected. Although failure in this cable could also cause loss of flow indication on two emergency feedwater lines, steam generator perability can be monitored by use of SG level indication. The safe shutdown requirements are satisfied.

Condensate Storage Tank Level FW -LT-4257 All cables are Train B. The Train A level transmitter FW -LT-4252 will be available. In addition, the cables for CST level transmitter CO -LT-4096 are not routed through this area. The Appendix R separation requirements are satisfied.

16. Pressurizer Pressure Transmitters RC

-PT-456, RC-PT-458 Redundant channels of pressurizer pressure cables are located in proximity. Spurious operation of two channels will initiate a safety injection signal. The operators will have the capability to terminate SI after 1 minute by use of the manual reset and block switch. All SI equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The provision of a capability to mitigate the spurious operation of the pressure transmitters outside the fire area satisfies the safe shutdown requirements.

17. Reactor Coolant Temperature RC

-TE-413B, RC-TE-423B, RC-TE-433B, RC-TE-443B All cold leg RC temperature element cables are routed through this area; however, this function can also be performed by the Train A steam generator pressure transmitters FW -PT-514, FW-PT-524, FW-PT-534, FW-PT-544 because cold leg temperature approximates the saturation temperature corresponding to secondary pressure. The cables for these PT 's are routed through fire area ET -F-1A-A. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-199 18. Containment Pressure Transmitters SI -PT-934, SI-PT-936 Redundant channels of containment pressure instruments and cables are located in proximity. Spurious operation of these channels will initiate safety injection, containment spray and containment isolation Phase A and Phase B. The operators will have the capability to terminate the SI after 1 minute by use of manual reset a nd block switches and terminate the containment spray and containment isolation by use of manual reset switches. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The provision of a capability to mitigate the spurious operation of the pressure transmitters outside the fire area satisfies the safe shutdown requirements.

19. Process Protection System Cabinet MM

-CP-2 Failure of cable will cause loss of power supply to Channel II process protection system cabinet and related instrumentation. The power supplies to redundant channel PPC are routed through other fire areas and; hence, the PPC 's will perform their safe shutdown function. The Appendix R separation requirements are satisfied.

20. Pressurizer Relief Valves RC

-PCV-456B, RC-V124 RC-PCV-456B is a normally closed, fail closed valve whose cables are in this fire area. The spurious opening of a PORV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. The PORV is supplemented with a normally open, series block valve RC-V122. For all fires that have the potential to cause spurious opening of the PORV, the operators will close the block valve by procedure. This will be the first step in the procedure and can readily be accomplished from the main control room. The promptness of this action is justification for the ability to isolate the block valve prior to any spurious valve operations. Under the condition, the initial short will not cause depressurization. To prevent subsequent spurious operations, the operators will de-energize the PORV and the block valve by tripping their power supply in the Train B switchgear room (Fire Area: CB -F-1B-A). The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-200 21. Containment Enclosure Isolation Damper, PAH -DP-35B, PAH-DP-36B Cables for dampers PAH -DP-35B and PAH -DP-36B are routed through this area. Under normal operation both dampers are open. If both dampers go closed, the Containment Enclosure Air Handling (EAH) system operates in the recirculation mode. The normal and recirculation modes for EAH system operation both satisfy the safe shutdown function. Independent operation of either damper (one open and one closed) could cause an air flow problem in EAH system. This assumes that redundant dampers (PAH -DP-35A and PAH -DP-36A) are in their normal open position since they would not be affected by a fire in this area. Both dampers are powered from a single Train B power supply. The circuit design is such that a spurious signal will cause both dampers to operate together, either both open (normal mode) or both closed (recirculation mode).

The safe shutdown requirements are satisfied.

22. High Head Safety Injection Valve SI

-V-139 SI-V-139 is a normally closed valve which may be opened to provide a redundant hot standby charging path. The functionally redundant Train A valve SI -V-138 is available to perform this function. Should SI -V-139 spuriously open, the charging pump may have to be stopped to prevent overfill of the pressurizer. The safe shutdown requirements are satisfied. C.

The area contains no in situ combustibles other than cables in trays and fiberglass ladders. There is one stack of three cable trays. The bottom tray is an enclosed instrument level tray located approximately 1 '-6" above the floor. The other trays are open ladder type trays which are located approximately 10 ' above the floor. The zone contains approximately 140 lineal ft. of ladder type tray. Detectors are provided throughout the area.

a. Containment Enclosure Ventilation Fans EAH

-FN-174A, EAH -FN-174B and Temperature Switches, EAH -TSH-5136, EAH -TSH-5763. Redundant ventilation fans and related cables are located in proximity. The purpose of these fans is to provide cooling for the Train A MSIV logic cabinets and the main steam pressure instrumentation. The failure of these fans will not prevent safe shutdown as the Train B logic cabinets and the main steam pressure transmitters FW -PT-514 and FW -PT-545 are not in the same fire area. The Train B logic cabinets are in the Train B switchgear room (Fire Area CB -F-1B-A) and the main steam pressure transmitters FW-PT-514 and FW -PT-545 are located in the west main steam and feedwater pipe chase (Fire Zone MS -F-1B-Z). These logic cabinets and pressure transmitters will perform their safe shutdown function. The Appendix R separation requirements are satisfied.

b. 460 Volt Motor Control Center EDE

-MCC-514 All cables are Train A. The redundant Train B cables are in Fire Area DCT-F-1B-0. The Appendix R separation requirements are satisfied.

Spurious operation of the channels will initiate safety injection and containment isolation Phase A signals. The operators will have the capability to terminate SI after one (1) minute by use of the manual reset and block switch and terminate the containment isolation by use of the manual reset switch. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B Switchgear Rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-209 Additionally main steam line pressure transmitters FW -PT-525 and FW-PT-534 utilized for process monitoring are located in the same fire areas. A fire could cause loss of indication from both main steam line pressure transmitters. However, the same fire would not affect pressure transmitters FW -PT-514 and FW -PT-545 which are functionally redundant and are located in the west main steam and feedwater pipe chase. (Fire Area: MS-F-1B-Z). These pressure transmitters and their associated atmospheric relief valves MS -PV-3001 and MS -PV-3004 will perform their safe shutdown function. The Appendix R separation requirements are satisfied.

d. Atmospheric Relief Valves MS

-PV-3002, MS-PV-3003 and Associated Solenoids. Valves MS -PV-3002 and MS -PV-3003 are normally closed valves. A fire could prevent operation of these valves. However, the same fire would not prevent the operation of valves MS -PV-3001 and MS -PV-3004 which are in the west main steam and feedwater pipe chase (Fire Area: MS -F-1B-Z, MS-F-2B-Z). Spurious opening of even one ARV can result in an overcooling condition in the RCS. This coupled with the potential unavailability of SI constitutes an unanalyzed condition. Since the ARV 's are air operated valves, their spurious operation will be prevented by assuring that these valves are placed in a state such that the initial spurious operation in the air supply will not cause the valve to open. This will be accomplished by procedure as one of the first steps for any fire that can affect the integral ARV air system cables. This action is justifiable since it can be accomplished from the main control room. To prevent a subsequent short that could override the initial action and cause the ARV to open, the affected air solenoids will be de -energized from the distribution panels located in Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). This will isolate the faulted air supply but will not preclude operation of the ARV since the redundant air solenoids will still be operational. The safe shutdown requirements are satisfied.

Main Steam Isolation Valves (MSIV) MS -V88 and MS -V90 and Logic Cabinet MS -CP-182, MS-CP-184. The valves MS -V88 and MS -V90 have no redundant counterpart, but they are supplied with redundant control capabilities. The Train A cables are routed in tray and conduit to the MSIV 's and their respective Train A logic cabinets. The Train B cables are routed in conduit on the opposite side of the MS & FW pipe chase. Their is a minimum horizontal separation of 10 ' up to the point that the conduits must run to the valves. The Train B conduits are routed approximately 15 ' above the floor. The MSIV 'S, connection boxes and electrical equipment are located approximately 25 ' above the floor. The Train B conduits are a minimum of 20 ' above the floor at the point they are in proximity to the Train A conduits. The Train A and Train B controls are on opposite sides of the MSIV approximately 2 ' apart. These valves are closed as an initial operator action. Should an MSIV reopen due to spurious operation (loss of power to both trains), the operators will isolate all feedwater to its respective steam generator and allow the SG to dry out. In the worst case this condition could occur to both MSIV 'S. The two steam generators and their associated MSIV 's in the west main steam and feedwater pipe chase (Fire Area: MS -F-1B-Z, MS-F-2B-Z) will be available for safe shutdown. The safe shutdown requirements are satisfied.

The cables and equipment in this Fire Area are associated with the Train A logic. The Train B logic cables and equipment are not routed through this fire area; hence, they will perform their safety function (MSIV trip). The Appendix R separation requirements are satisfied.

a. The PAB is a Class 1 concrete structure which contains the above listed equipment and cable required for safe shutdown. The PAB has been divided into several zones for fire protection analysis, with intervening walls, floors and ceilings of poured concrete.

b. The significant in situ combustibles consist of 0.2 gallon of oil in each of the two boron injection pumps; 1.0 gallon of oil in the monorail crane hoists; 1.0 gallon of oil in each of the two chiller pumps; 0.25 gallon of oil in each of the two reactor makeup water pumps; 1.0 pound of grease in each of the two boric acid transfer pumps; 1.0 gallon of oil in each of the four primary component cooling pumps; 0.5 gallon of oil in each of the two flash tank distillate pumps; 32,500 lbs. of charcoal within filters PAH-F-16 and CAP

-F-40 and 19,000 pounds of insulation for cables in trays. The analysis of the in situ fire load provided by the cable in trays is contained in the "Zone Analyses ". An analysis of the Design Basis Fires for the remaining combustibles is contained in the "Fire Protection Program Evaluation of Comparison to Branch Technical Position APCSB

9.5-1, Appendix A" and is summarized as follows:

1) Elevation 7'-0" and Below a) Fire Zone PAB

-F-1A-Z Total fire loading for 6.0 gallons of oil is 900,000 Btu (chiller pumps CS -P-7A, and CS -P-7B and reactor makeup water pumps RMW -P-16A and RMW -P-16B), and the fire loading for fiberglass ladders is (28 pounds plastic) 364,000 Btu. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-237 b) Fire Zone PAB -F-1J-Z Limited in situ combustibles in pumps. c) Fire Zone PAB -F-1K-Z No combustibles

2) Elevation 25

'-0" a) Fire Zone PAB -F-2A-Z Total fire load for fiberglass ladders is (71 pounds plastic) 923,000 Btu . b) Fire Zone PAB-F-2B-Z Total fire loading for 2.0 pounds of grease is 36,000 Btu (boric acid transfer pumps CS -P-3A and CS -P-3B). c) Fire Zone PAB -F-2C-Z Total fire loading for 5.25 gallons of oil is 787,500 Btu (PCCW pumps CC -P-11A, 11B, 11C and 11D; 31/2 ton monorail crane hoist CS -CR-13; 41/2 ton monorail crane hoist CS-CR-5; boron injection pumps SI -P-4A and SI -P-4B). 3) Elevation 53 '-0" a) Fire Zone PAB -F-3A-Z Total fire loading for 1.0 gallon of oil is 150,000 Btu (flash tank distillate pumps SB -P-171A and SB -P-171B). SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-238 b) Fire Zone PAB -F-3B-Z Total fire loading for 0.5 gallon of oil is 75,000 Btu (41/2 ton monorail crane hoist CS -CR-6) and for 50 pounds of Class A material is 400,000 Btu and for fiberglass ladders is (71 pounds plastic) 923,000 Btu. See "Fire Protection Program Evaluation and Comparison to Branch Technical Position APCSB 9.5 -1 Appendix A" for analysis of 6600 lbs. of charcoal in CAP -F-40. c. The Train A safe shutdown cables are routed in trays. The Train B safe shutdown cables are routed in conduits with a one -hour, fire -rated barrier from the fire area boundary where they enter the PAB to the fire area boundary where they exit or the equipment at which they terminate, except as discussed in the zone analyses.

d. Detectors are provided in all zones of the PAB with the exception of Fire Zones PAB

-F-1B-Z, PAB-F-1F-Z and PAB -F-1K-Z. e. Suppression is provided in Fire Zone PAB -F-2C-Z. Details are provided in the zone analysis.

f. Early fire detection by use of carbon monoxide detectors within the

charcoal filter CAP -F-40 is provided.

g. Volume control tank (VCT) isolation valves CS

-LCV-112B & -112C are normally open to provide a suction path from the VCT to the normally operating charging pump (CS -P-2A or -2B). These valves must stay open until RWST valve CS -LCV-112D or -112E is manually opened to provide a charging pump suction path from the RWST, or the boric acid tanks are manually aligned as a charging pump suction source. Spurious closure of a VCT isolation valve caused by a hot short would interrupt suction flow to the operating charging pump causing it to be damaged. If the standby charging pump has cables in the same area then its operation can also be degraded. The result would be no charging system flow. The following PAB fire zones have been combined into one fire area for analysis purposes: PAB-F-1A-Z, PAS-F-1J-Z, PAB-F-1K-Z, PAB-F-2A-Z, PAB-F-2B-Z, PAB-F-2C-Z, PAB-F-3A-Z, and PAB -F-3B-Z. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-239 Since this combined fire area contains cables for CS -LCV-112B, CS-LCV-112C, CS-P-2A and CS -P-2B, this condition is potentially applicable for the system alignment with either combination of CS -P-2A and CS-P-2B as the standby pump and operating pump. The CS-LCV-112B and CS -LCV-112C circuit design prevents spurious valve closure from hot shorts as follows. The field cable conductors for the motor control center (MCC) contactor close coil circuit are in different cables than the 120 V "hot" circuit conductors eliminating the hot short failure mode within the cables. Cable -to-cable hot shorts need not be postulated for thermoset cable insulation as used at Seabrook. Also, the barriered conduit for CS -LCV-112C prevents Train B cable damage. Since CS-LCV-112B and CS -LCV-112C will not spuriously close, CS-P-2A or -2B as the operating charging pump will not be damaged.

b. Fire Zone PAB

-F-1J-Z (Tabulation 3.2.7.66)

1) Specific Zone Analysis This zone at Elevation (

-) 6'-0" and (-) 26'-0" of the PAB is bounded by concrete floors, ceiling and walls with penetrations to other zones. The zone is approximately 96 ' long by 75 ' wide by 11 ' to 18' high with floor area of 1980 sq. ft. and a volume of 23,782 cu. ft. All Train B safe shutdown cables are routed in conduit with a one-hour, fire -rated barrier. Combustibles are limited to cables in open trays with a total fire loading of 500 Btu per sq. ft. and limited in situ combustibles in pumps. Detectors are provided throughout the zone.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-244 2) System Analyses a) Primary Component Cooling Water (CC) System This zone contains cables routed in tray for the Train A valves CC -V175 and CC -V257. The tray is minimum of 10' above floor elevation ( -) 26'-0". Only 6 linear feet of the tray is in the zone. The redundant Train B cables are routed in barriered conduit above floor elevation ( -) 8'-0" in Fire Zone PAB -F-1Z-Z, which is approximately 18 ' horizontally above the Train A cables with an intervening concrete floor. b) Chemical and Volume Control (CS) Syst em This zone contains equipment and cables in conduit required for operation of Train A Valve CS -FCV-121 which provides a redundant charging flow path to Train B Valve SI-V139. The redundant Train B cables are routed in barriered conduit in Fire Zone PAB -F-1A-Z and are separated from the Train A cables by concrete floors and walls. Valve CS-V158 provides redundant seal cooling capabilities to the safety grade thermal barrier cooling. Cables, controls and equipment for the Train A thermal barrier cooling capability are not contained in the PAB fire area and will be available for safe shutdown. Redundant valves CS -V196 and CS -V197 are located in the same fire zone and are separated by approximately 3 ' horizontal separation. These valves are normally open

valves that remain open for Safe Shutdown. The spurious closure for one valve will not prevent shutdown. The operators will prevent further spurious operation by tripping the power supply breakers at the Train A or Train B switchgear rooms (Fire Areas: CB -F-1A-A or CB-F-1B-A). See additional CS system discussion on CS -LCV-112B, CS-LCV-112C, CS-P-2A and CS -P-2B in the General Area Analysis, Section B.1.g.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-245 c) Reactor Coolant (RC) System This zone contains cables routed in tray for the Train A valves RC -V23 and RC-V88. The cables are part of the position indicating light circuit for valves that have been permanently disabled. Failures in this circuit will not prevent the opening of the valves for cold shutdown. d) Safety Injection (SI) System This zone contains cables routed in tray for the Train B valve SI-V139. The tray is a minimum of 10 ' above floor Elevation ( -) 26'-0". Only six lineal feet of the tray is in the zone. The redundant Train B cables are routed in barriered conduit above floor Elevation (-) 8'-0" in Fire Zone PAB-F-1A-Z, which is approximately 18 ' horizontally above the Train A cables with an intervening concrete floor. Redundant channels of containment pressure (SI -PT-936 and SI-PT-937) cables are located in proximity. Spurious operation of these channels will initiate containment spray and containment isolation Phase B. The operators will have the capability to terminate these protective actions by use of manual reset switches. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CB-F-1A-A and CB-F-1B-A). SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-246 3) Summary For CC and SI systems above, the routing of the Train B cables in conduit with a one -hour, fire -rated barrier; the height of the Train A an B raceways, the provision of a capability to mitigate the spurious operation of the pressure transmitters outside the fire area; and considering the low combustibles loading in the zone provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III G.2.c "in addition to 1 hour fire barrier, an automatic fire suppression system shall be installed ", has been approved. For CS system above, the routing of the Train B cables in conduit with a one -hour, fire -rated barrier; and the low combustibles loading in the zone provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III G.2.c in addition to 1 hour fire barrier, an automatic fire suppression system shall be installed ", has been approved. For RC system above, the safe shutdown requirements are satisfied.

c. Fire Zone PAB

-F-1K-Z (Tabulation 3.2.7.67)

1) Specific Zone Analysis This zone between Elevation (

-) 6'-0" and roof Elevation 81 '-0" of the PAB is bounded by concrete floors, ceilings and walls with penetrations to other zones. The zone is approximately 68 ' long by 9' wide by 75 ' high with a floor area of 4,620 sq. ft. and a volume of 75,370 cu. ft. There is no tray in the zone and all cables are routed in conduit. All Train B safe shutdown cables are routed in conduit with a one-hour, fire -rated barrier. There are no in situ combustibles in the zone.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-247 2) System Analyses a) Chemical and Volume Control (CS) System This zone contains cables routed in conduit for Train A valves CS -LCV-112B and CS -LCV-112D. The Train B cables for their redundant counterpart valves CS-LCV-112C and CS -LCV-112E are routed in barriered conduit in the zone. There is 13 ' horizontal separation between the conduits containing the redundant cables. See additional CS system discussion on CS -LCV-112B, CS-LCV-112C, CS-P-2A and CS -P-2B in the General Area Analysis, Section B.1.g. b) PAB Air Handling (PAH System) This zone contains cables routed in conduit to Train A damper PAH -DP-43A. The Train B cables to redundant damper PAH -DP-43B are routed in barriered conduit in the zone. The only exception to the barrier is a short length of flexible conduit whose wrapping would interfere with the damper operator. The dampers are located approximately 15' above the floor. The area containing the dampers is a concrete and steel enclosed air plenum with limited access and no combustibles. These dampers and the fans which they control are not needed unless the main ventilation system is lost due to loss of off-site power or unless the temperature in the PCCW area exceeds 40C (104F). SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-248 c) Service Water (SW) System This zone contains cables routed in conduit for Train A valve SW-V4. The Train B cables for its redundant counterpart valve SW-V5 are routed in barriered conduit in the zone. The only exception to the barrier is one cable which runs in flexible conduit between a limit switch on valve SW-V5 to its motor operator. There is 8 ' horizontal separation between the barriered conduit for valve SW -V5 and valve SW -V4. There is 16 ' horizontal separation between the redundant valves. The valves are located approximately 15 ' above floor Elevation 53 '-0" and 3' above platform Elevation 65 '-0. This zone also contains cables routed in conduit for Train A valve SW-V74. The position of this valve is only important when the Train A cooling tower capabilities are in use at which time the valve should be closed and should remain closed. In the event this valve opens spuriously, the operators can either transfer the Train A service water to the pumphouse or utilize the Train B service water system. This satisfies the safe shutdown requirements.

3) Summary For the CS system above, the routing of the Train B cables in conduit with a one

-hour, fire-rated barrier; the spatial separation between the Train A and Train B conduits; and considering the absence of in situ combustibles in the zone provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III G.2.c "in addition to 1 hour fire barrier, an automatic fire suppression system shall be installed ", has been approved.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-249 For the PAH system above, the routing of the Train B cables in conduit with a one -hour, fire-rated barrier; the height of the dampers above the floor; the absence of in situ combustibles in the zone and the fact that a fire in the area could not cause loss of off-site power, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III.G.2 has been approved. For the SW system above, the routing of the Train B cables in conduit with a one -hour, fire -rated barrier; the horizontal separation of 8 ' between conduit and valve and 16 ' between the valves themselves; the height of the valves from the floor; and considering the absence of in situ combustibles in the zone provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III G.2.c "in addition to 1 hour fire barrier, an automatic fire suppression system shall be installed ", has been approved.

d. Fire Zone PAB

-F-2A-Z (Tabulation 3.2.7.68)

1) Specific Zone Analysis This zone at Elevation 25

'-0" of the PAB is bounded by concrete floor, ceiling and walls (South and East) and is contiguous to fire zones PAB -F-2B-Z and PAB -F-2C-Z. The northern boundary consists of partial height concrete walls and an 11 ' wide access passage. The western boundary consists of full height concrete walls and metal partitions. There are penetrations for tray, ducts, and pipes to other fire zones. The zone is approximately 44 ' long by 39' wide by 26 ' high with a floor area of 1550 sq. ft and a volume of 40,000 cu ft. No safe shutdown equipment is contained in the zone, only safe shutdown cables. Combustibles are 71 pounds of plastic (fiberglass ladders) for a total fire loading of 596 Btu per sq. ft. of floor area and limited in situ combustibles. This is classed as a low fire load. Detectors are provided throughout the zone.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-250 2) System Analyses a) Chemical and Volume Control (CS) System This zone contains cables routed in tray for the redundant boric acid tank level transmitters CS -LT-102 and CS-LT-106. These tank levels are only required once cooldown has been initiated. Should both transmitter cables be damaged by a fire, the operators can utilize the Train B level transmitter CS -LT-7464. This transmitter and its associated cable are not contained in this fire zone. The indicator for this transmitter is located at the RSS panel in the Train B switchgear room (Fire Area: CB -F-1B-A). This zone contains cables routed in tray and conduit for the boric acid pump CS -P-3A and for the boric acid to charging pumps isolation valve CS -V426. Cables for the redundant Train B boric acid pump CS -P-3B are routed in barriered conduits in Fire Zones PAB -F-2B-Z and PAB -F-2C-Z. Valve CS-V426 has no electrically operated redundant counterpart. Should the valve be damaged by a fire, the operator will establish a gravity path from the BAT 's to the charging pump suction by the repositioning to manual valves in the boric acid pump room (Fire Zone PAB-F-2B-Z). These valves are not required to be operated until boric acid is required for shutdown reactivity. This would be up to four hours into the event. See additional CS system discussion on CS -LCV-112B, CS-LCV-112C, CS-P-2A and CS -P-2B in the General Area Analysis, Section B.1.g.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-251 This zone contains cables for CS-FCV-110A, -111A, -110B, -111B. Spurious opening of these valves in conjunction with spurious start of a boric acid transfer pump or reactor makeup water pump may divert boric acid from the reactor coolant system affecting cold shutdown reactivity control, or result in an unplanned dilution affecting hot standby and cold shutdown reactivity control. The operators isolate the diversion flow by closing

CS-FCV-110B & -111B using the main control board control switches. The operators isolate the dilution flow by closing CS -LCV-112B or CS -LCV-112C using the main control board control switch. b) Containment Enclosure Air Handling (EAH) System This zone contains cable routed in barriered conduit for the Train B fan EAH -FN-5B. The cables for the redundant Train A fan EAH -FN-5A are routed in trays in fire zone PAB-F-2C-Z. There is approximately 16 ' horizontal separation between the barriered conduit and the redundant tray. c) Electrical Distribution Emergency (EDE) System All cables are Train A. The functionally redundant cables are located in other fire areas.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-252 d) PAB Air Handling (PAH) System Cables and equipment for outboard isolation dampers PAH-DP-35A and PAH -DP-36A and inboard isolation dampers PAH -DP-35B and PAH -DP-36B are routed in trays and conduits in proximity to one another. Under normal operation both outboard and both inboard dampers are open. If both outboard or both inboard dampers go closed, the Containment Enclosure Air Handling (EAH) system operates in recirculation mode. The normal and recirculation modes for EAH system operation both satisfy the safe shutdown function. If the outboard dampers and the inboard dampers operate independently such that either the supply or the exhaust path but not both are isolated, there could be an air flow problem in EAH system. Outboard dampers are powered from a single Train A power supply. Inboard dampers are powered from a single Train B power supply. The circuit design for the outboard and inboard dampers is such that a spurious signal in either or both circuits will cause both outboard and inboard dampers to operate together, either both open (normal mode) or both closed (recirculation mode). This zone contains cables routed in tray for the Train A fan PAH-FN-42A and damper PAH -DP-357. The cables for the redundant Train B fan PAH -FN-42B and damper PAH-DP-358 are routed in barriered conduit in fire zone PAB-F-2C-Z. There is greater than 50 ' of horizontal separation between the tray and the redundant barriered conduit. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-253 e) Service Water (SW) System This zone contains cable routed in tray for the Train A pumps SW-P-41A and SW -P-41C and valve SW -V54. The cables for the redundant Train B pumps SW -P-41B and SW-P-41D and valve SW -V25 are routed in barriered conduits in fire zone PAB -F-1A-Z. There is approximately 25' of horizontal separation between the tray and the redundant barriered conduits. For the other Train A cables routed in this zone, the redundant cables and equipment are contained in other fire areas. f) Service Water Air Handling (SWA) System All cable are Train A, the redundant cables are located in other fire areas.

3) Summary For the CS system above, the provision of a manual valve alignment capability that is not required for up to four hours into the event satisfies the safe shutdown requirements. Also, the capability to isolate the boric acid diversion flow and the dilution flow using the main control board control switches satisfies the safe shutdown requirements.

For the EAH, PAH and SW systems above, the routing of the Train B cables in a one -hour, fire -rated barrier; the horizontal separation of 16 ', 25' and 50' respectively; and the low combustibles loading in the zone, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III.G.2.c, "in addition to 1 hour fire barrier, an automatic fire suppression system shall be installed ", has been approved. For the EDE and SWA systems above, the Appendix R separation requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-254 e. Fire Zone PAB -F-2B-Z (Tabulation 3.2.7.69)

1) Specific Zone Analysis This zone at Elevation 25

'-0" of the PAB is bounded by concrete floor, ceiling and walls (South and West) and is contiguous to fire zones PAB -F-2A-Z and PAB -F-2C-Z. The northern and eastern boundaries consists of full height concrete walls and metal partitions. There are penetrations for tray, ducts and pipes to other fire zones. The zone is approximately 28 ' long by 37 ' wide by 16 ' high with a floor area of 1300 sq. ft. and a volume of 33,800 sq. ft. Combustibles are limited to 2.0 pounds of grease for a fire loading of 36,000 Btu and cables in open trays for a total fire loading of 6000 Btu per sq. ft. of floor area. Detectors are provided throughout the zone.

2) System Analyses a) Chemical and Volume Control (CS) System The redundant boric acid tank level transmitters CS

-LT-102 and CS-LT-106 are located in the same fire zone. Should both transmitters be unavailable due to fire damage, the operators can utilize the Train B level transmitter CS-LT-7464. This transmitter and its associated cable are contained in this fire zone. The indicator for this transmitter is located on the RSS panel in the Train B switchgear room (Fire Area: CB -F-1B-A). Should all level transmitters be unavailable, the operators will open the cross-connect valve s CS-V437 and CS -V1207 and boric acid tank isolation valves CS -V410 and CS -V416 allowing charging pump suction from both boric acid tanks. The combined inventory of the two tanks is sufficient to complete the cooldown thus eliminating the need for tank level monitoring.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-255 Redundant boric acid pumps CS -P-3A and CS -P-3B and the valve CS -V426 are located in the same fire zone. Should both pumps or the valve be damaged by the fire, th e operators will establish a gravity flow path from the BAT 's to the charging pump suction by repositioning of manual valves in the fire zone. Valves CS -V410, CS-V416, CS-V437, CS-V1207, CS-V439 and CS -V442 are manual valves required for gravity feed from the boric acid tanks to the charging pumps or cross-connecting the boric acid tanks in response to a loss of level indication. These valves are not required to be operated until boric acid is required for shutdown reactivity. This would be upon commencement of cooldown, up to four hours into the event, and the valves would then be accessible for manual operation. During this time the plant would be maintained in hot standby with RC inventory makeup provided by the RWST. See additional CS system discussion on CS -LCV-112B, CS-LCV-112C, CS-P-2A and CS -P-2B in the General Area Analysis, Section B.1.g.

This zone contains cables for CS-FCV-110A, -111A, -110B, -111B and the valves. Spurious opening of these valves in conjunction with spurious start of a boric acid transfer pump or reactor makeup water pump may divert boric acid from the reactor coolant system affecting cold shutdown reactivity control, or result in an unplanned dilution affecting hot standby and cold shutdown reactivity control. The operators isolate the diversion flow by closing CS -FCV-110B & -111B using the main control board control switches. The operators isolate the dilution flow by closing CS -LCV-112B or CS-LCV-112C using the main control board control switch.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-256 b) PAB Air Handling (PAH) System This zone contains cables routed in tray and conduit for the Train A fan PAH -FN-42A and dampers PAH -DP-43A and PAH-DP-357. The cables for the redundant Train B fan PAH-FN-42B and dampers PAH -DP-43B and PAH-DP-358 are routed in barriered conduit in fire zone PAB-F-2C-Z. There is 4 ' horizontal separation between the Train A raceways and the Train B equipment and barriered conduit. The Train A trays are a minimum of 8 ' above floor Elevation 25 '-0". A total of 3 trays exist in the stack with the bottom tray an enclosed instrument level tray containing no Safe Shutdown cables. The Train B damper PAH-DP-358 is located approximately 18 ' above floor Elevation 25 '-0". 3) Summary For the CS system above, the provision of a manual valve alignment capability that is not required for up to four hours into the event satisfies the safe shutdown requirements. Also, the capability to isolate the boric acid diversion flow and the dilution flow using the main control board control switches satisfies the safe shutdown requirements. For the PAH system above, the routing of the Train B cables in conduit with a one -hour, fire -rated barrier in another zone of the PAB; the 4 ' horizontal between the Train A and Train B equipment; the 8 ' height of the tray above the floor; and considering the low combustibles loading in the zone, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III G.2.c. "in addition to 1 hour fire barrier, automatic fire suppression system shall be installed ", has been approved.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-257 f. Fire Zone PAB -F-2C-Z (Tabulation 3.2.7.70)

1) Specific Zone Analysis This zone at Elevation 25

'-0" of the PAB is bounded by concrete floors, ceilings and walls (North, East and West) and is contiguous to fire zones PAB -F-2A-Z and PAB -F-2B-Z to the South. The southern boundary consists of full height partitions, full and partial height concrete walls and an 11' wide access passage. There are penetrations for tray, ducts and pipes to other fire zones. The zone is approximately 100 ' long by 75 ' wide by 26 ' high with a floor area of 7,200 sq. ft. and a volume of 187,000 cu. ft. The trays installed at Elevation 25 '-0" are in stacks five and six high by four wide, as a worst case, with a minimum of 4 ' between the Train A and Train B stacks. There are several areas where the trays have vertical drops through the floor. With a limited number of exceptions, the trays are a minimum of 10 ' above the floor. Metal covers are provided around the vertical trays near column lines 2 and C. The in situ combustibles are limited to cables in open trays which provide a fire load of 16,000 Btu per square foot of floor area; the boron injection pumps which contain 0.25 gallons of oil are a fire loading of 37,500 Btu; the primary component cooling water pumps CC-P-11A, 11B, 11C and 11D containing a total of four gallons of oil for a fire loading of 600,000 Btu; 41/2 ton monorail crane hoist CS -CR-5 containing 0.5 gallons of oil for a fire loading of 75,000 Btu; and 31/2 ton monorail crane hoist CS -CR-13 containing 0.5 gallons of oil for a fire loading of 75,000 Btu. The concentrated fire load in this zone is 30,000 Btu per squar e foot of tray. Because of the concentrated fire load, we have installed sprinklers to control transient fires in the area of the trays. To protect the PCCW pumps against a fire from a transient combustible, we have installed a pre -action system, using high temperature heads over the pumps and the surrounding area. Spray shields will be installed over the PCCW pump motors. Detectors are provided throughout the zone.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-258 2) System Analyses a) Primary Component Cooling Water (CC) System The redundant Primary Component Cooling Water (PCCW) pumps are located in the same fire area. The CC System is configured such that there are two 100% capacity PCCW pumps in each train either of which can be utilized for safe shutdown. The spatial separation between Train A pump CC-P-11A and Train B pump CC -P-11D is in excess of 20' with a metal partition between them. The spatial separation between Train A pump CC -P-11C and Train B pump CC-P-11B is in excess of 20 ' with a metal partition between them. The cables to the Train B pumps are routed in barriered conduit from the point they enter the PAB to the pump motors. The conduits are barriered in the vicinity of the Train B pumps. The Train B pumps have a spatial separation of 25 ' from the Train A trays and 15 ' from the Train B trays. The redundant PCCW heat exchanger valves CC-TV-2171-1, 2 and CC -TV-2271-1, 2 and their associated controls and instrument rack MM -IR-93 are located in the same fire area. The cables for the Train B valves CC -TV-2271-1 and CC-TV-2271-2 and the Train B controllers are routed in barriered conduits. The only exception is a reduction in the barriers at the controllers and valves due to interference with instrument lines. The redundant valves are mounted approximately 20 ' above the floor with a minimum separation of 2 '. The controllers are wall and instrument rack mounted and are separated by approximately 20 '. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-259 The redundant temperature elements CC -TE-2171, CC-TE-2197 and CC -TE-2271, CC-TE-2297 are located in the same fire area. The cable for one of the redundant Train B temperature elements is routed in a barriered conduit. The trip logic is a 2 out of 2 logic. The redundant temperature elements have a horizontal separation of approximately 8 ' and are mounted on 24 " component cooling water pipes approximately 20 ' above the floor. Cables for the redundant head tank level transmitters are in proximity. Failures in these cables could initiate a spurious

lo-lo-head tank level isolation signal. This in turn would result in closure of the PCCW containment isolation valves. These valves are only required when it is necessary to maintain containment habitable for containment entry to manually operate the RHR isolation valves and the SI accumulator isolation valves. The circuitry for these valves is not affected by a fire in this area; hence, they would be operable from the MCR. Therefore, the spurious operation of these transmitters will not prevent safe shutdown. b) Chemical and Volume Control (CS) System This zone contains cables in tray required for operation of Train A valve CS -FCV-121, which provides one of the required hot standby charging flow paths. The redundant Train B valve SI -V139 cables are routed in barriered conduit in Fire Zone PAB -F-1A-Z and are separated from the Train A cables by concrete floors. For cooldown, the operators will manually align the Train B charging pump discharge and bypass valves (CS-V219 and CS -V220) to the seal injection flow path and throttle the bypass valve as required. This operator action can be delayed for up to of 4 hours into the event. This zone contains cables in barriered conduit for the charging to RCS isolation valve CS -V143. The cables for the redundant valve CS -V142 are not contained in this fire area. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-260 This zone contains cables routed in tray for the redundant boric acid tank level transmitters CS -LT-102 and CS-LT-106. These tank levels are only required once cooldown has been initiated. Should both transmitter cables be damaged by a fire, the operators can utilize the Train B level transmitter CS -LT-7464. This transmitter 's cable is contained in this fire zone. The indicator for this transmitter is located at the RSS panel in the Train B switchgear room (Fire Area: CB -F-1B-A). Should all level transmitters be unavailable, the operators will open th e cross-connect valve CS -V437 allowing charging pump suction from both boric acid tanks. The combined inventory of the two tanks is sufficient to complete the cooldown thus eliminating the need for tank level monitoring. This zone contains cables routed in tray and conduit for the redundant boric acid pumps CS -P-3A and CS -P-3B and for the valve CS -V426. Should both pumps or the valves be damaged by a fire, the operator will establish a gravity path from the BAT 's to the charging pump suction by the repositioning of manual valves in the boric acid pump room (Fire Zone PAB -F-2B-Z). Some of these valves are also required to cross -connect the boric acid tanks in response to a loss of level indication (see above discussion). These valves are not required to be operated until boric acid is required for shutdown reactivity. This would not be required for up to four hours into the event. This zone contains cables routed in tray and conduit for the Train A charging pump CS-P-2A. The cable for the redundant Train B pump CS -P-2B are routed in a barriered conduit in Fire Zone PAB -F-1A-Z. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-261 The zone contains cables routed in tray and conduit for the redundant valves CS -LCV-112B, CS-LCV-112D, CS-LCV-112C and CS -LCV-112E. The cables for valves CS-LCV-112C and CS -LCV-112E are routed in barriered conduits. The only exception is at an interference with fire detectors where the one -hour wrap is reduced to allow air flow to the detector. At the point of the reduced one -hour wrap, there is a minimum of 20 ' of horizontal separation to functionally redundant cables. See additional CS system discussion on CS -LCV-112B, CS-LCV-112C, CS-P-2A and CS -P-2B in the General Area Analysis, Section B.1.g.

This zone contains cables for CS-FCV-110A, -111A, -110B, -111B. Spurious opening of these valves may divert boric acid from the reactor coolant system affecting cold shutdown reactivity control, or result in an unplanned dilution affecting hot standby and cold shutdown reactivity control. The operators isolate the diversion flow by tripping the control circuit power supply breaker to close CS -FCV-110B & -111B (valves fail closed). The operators isolate the dilution flow by closing

CS-LCV-112C using the main control board control switch. This zone contains cables routed in trays for valve CS-V196. The cables for the redundant Train B valve CS-V197 are routed in a barrier conduit in Fire Zone PAB-F-1A-Z. c) Containment Enclosure Air Handling (EAH) System The cables for the redundant fans EAH -FN-5A and EAH-FN-5B, are routed in tray and conduits in the same area. All the Train B fan cables are routed in barriered conduits, which are separated from the Train A cables by a minimum of 18 '. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-262 Cables for redundant equipment vault return fans EAH-FN-31A and EAH -FN-31B are routed in trays and conduits in proximity to one another. These fans are required to maintain the equipment vaults habitable for entry if manual operations are required to place RHR into operation for cold shutdown. A fire in the PAB fire area will not prevent operation from the MCR of any equipment necessary for RHR operation; hence, habitability of the equipment vaults is not required. Analysis and field testing has confirmed that the containment enclosure supply fans EAH-FN-5A and EAH-FN-5B are sufficient to maintain the equipment vaults below the equipment 's qualified temperatures. d) Electrical Distribution Emergency (EDE) System All cables are Train A. The functionally redundant cables are located in other fire areas. e) PAB Air Handling (PAH) System Cables and equipment for outboard isolation dampers (PAH-DP-35A and PAH -DP-36A and inboard isolation dampers PAH -DP-35B and PAH -DP-36B are routed in trays and conduits in proximity to one another. Under normal operation both outboard and both inboard dampers are open. If both outboard or both inboard dampers go closed, the Containment Enclosure Air Handling (EAH) system operates in recirculation mode. The normal and recirculation modes for EAH system operation both satisfy

the safe shutdown function. If the outboard dampers and the inboard dampers operate independently such that either the supply or the exhaust path but not both are isolated, there could be an air flow problem in EAH system.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-263 Outboard dampers are powered from a single Train A power supply. Inboard dampers are powered from a single Train B power supply. The circuit design for the outboard and inboard dampers is such that a spurious signal in either or both circuits will cause both outboard and inboard dampers to operate together, either both open (normal mode) or both closed (recirculation mode). The redundant PAH fans (PAH -FN-42A and PAH-FN-42B) and dampers (PAH -DP-43A, PAH-DP-357, PAH-DP-43B and PAH -DP-358) are in proximity. The fans and dampers are inside separate metal enclosures located approximately 15 ' above the floor. The Train B fan and damper cables are routed in barriered conduits. The only exception to the barrier is short lengths of flexible conduit whose wrapping would interfere with damper

operator PAH -DP-358. There are no cable trays in the vicinity of the fans and dampers. The only in situ combustibles in the vicinity are in the PCCW pumps which are separated from the fans and dampers by greater than 20 ' horizontally and the monorail crane hoist. These fans are not needed unless the main ventilation system is lost due to the loss of off -site power or unless the temperature in the immediate area exceeds 40C (104F). The redundant temperature switches PAH -TSH-5391 and PAH-TSH-5393 and conduits containing their cables are located in proximity. Failure of these switches or their cables could prevent operation of fans PAH -FN-42A and PAH-FN-42B. Should the switches or cables fail, the operators can isolate the affected portion of the circuit at the RSS facilities in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A) and restart the fans.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-264 f) Service Water (SW) System This zone contains cables routed in tray for the Train A pumps SW-P-11A and SW -P-11C and valve SW -V54. The redundant Train B pumps and valve cables are routed in a barriered conduit in Fire Zone PAB -F-1A-Z which is separated from this zone by an intervening concrete floor. The cables for redundant valves SW -V4, SW-V16, SW-V5 and SW-V18, are located in the same fire zone. These valves may be required to reposition to isolate secondary component cooling water or for DG cooling. The Train B valves SW -V5 and SW -V18 cables are routed in barriered conduits and are separated from the Train A cables by greater than 30' horizontally. There are no cable trays or other in situ combustibles in the vicinity of Train B conduits. The cables for redundant valves SW -V-15 and SW -V17 are located in the same fire zone. These valves are normally in their safe shutdown position to provide cooling to the PCCW heat exchangers. In addition, the circuit breaker for

SW-V17 is administratively controlled off so the valve cannot spuriously close. If SW -V15 spuriously closes, SW-V17 is still open to provide the Train B PCCW heat exchanger cooling function. Redundant valves SW -V20, SW-V34 and SW -V19, SW-V23 are located in the same fire zone. Operators for valves SW -V34 and SW -V23 are approximately 5 ' above floor Elevation 25 '-0" and operators for valves SW -V20 and SW-V19 are approximately 10' above floor Elevation 25'-0". The redundant valves are separated by approximately 16 ' horizontally. There are no cable trays in the vicinity of the valves. The only in situ combustibles in the vicinity are the PCCW pumps which are separated from the Train A valves by greater than 16 ' horizontally. The valves are in Safe Shutdown position. The operators will prevent spurious operation by tripping the power supply breakers at the Train A and Train B Switchgear Rooms (Fire Area: CB -F-1A-A and CB-F-1B-A). SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-265 For the other Train A cables routed in this zone, the redundant cables and equipment are contained in other fire areas. g) Service Water Air Handling (SWA) System All cables are Train A. The redundant functionally cables are located in other fire areas. 3) Summary For the CC system above, the routing of the Train B cables in conduit with a one -hour, fire -rated barrier; the spatial separation; and the provision of the sprinkler system, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. For the CS system charging pumps and the related CS and SI valves above, the routing of the Train B cables in conduit with a

one-hour, fire -rated barrier and the provision of suppression in the area of the trays and the PCCW pumps, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. For the CS system transmitters, boric acid pumps and related valve above, the provision of a manual valve alignment capability that is not required for up to four hours into the event satisfies the safe shutdown requirements. Also, the capability to isolate the boric acid diversion flow by tripping the control circuit power supply breaker and isolate the dilution flow using the main control board control switches satisfies the safe shutdown requirements. For the EAH system supply fans above, the routing of Train B cables in conduit with a one -hour, fire -rated barrier and the provision of suppression in the area of the trays and the PCCW pumps, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. For the EAH system return fans above, the safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-266 For the PAH dampers above, the safe shutdown requirements are satisfied. For the PAH fans and related dampers above, the routing of the Train B cables in conduits with a one -hour, fire -rated barrier; the height of the fans off the floor; the lack of combustibles in the area of the fans and the fact that a fire in the area could not cause loss of offsite power, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. For the PAH temperature switches above, the safe shutdown requirements are satisfied. For the SW system above, the routing of the Train B cables in a conduit with a one -hour, fire -rated barrier; the spatial separation and the provision of the sprinkler system, provide acceptable fire protection and provide protection equivalent to the technical requirement of Appendix R. For the EDE and SWA systems above, the Appendix R separation requirements are satisfied.

g. Fire Zone PAB

-F-3A-Z (Tabulation 3.2.7.71)

1) Specific Zone Analysis This zone at Elevation 53

'-0" of the PAB is bounded by concrete floor, ceiling and walls (North, East and West) and is contiguous to fire zone PAB -F-3B-Z to the South. The southern boundary consists of a full height partition wall. There are penetrations for tray, ducts and pipes to other fire zones. The zone is approximately 53 ' long by 75 ' wide by 26 ' high with a floor area of 4000 sq. ft. and a volume of 103,400 cu. ft. Combustibles are limited to 1.0 gallon of oil for a fire loading of 150,000 Btu and cables in open trays for a total fire loading of 3000 Btu per sq. ft. of floor area. Detectors are provided throughout the zone.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-267 2) System Analyses a) Primary Component Cooling Water (CC) System Redundant transmitters and cables for head tank level logic are in proximity. Failures in these transmitters or cables could initiate a spurious lo -lo head tank level isolation signal. This in turn, would result in closure of the PCCW containment isolation valves. These valves are only required when it is necessary to maintain containment habitable for containment entry to manually operate the RHR isolation valves and the SI accumulator isolation valves. The circuitry for these valves is not affected by a fire in this area; hence they would be operable from the MCR. Therefore, the spurious operation of these transmitters will not prevent safe shutdown. b) Chemical and Volume Control (CS) System This zone contains cables routed in tray for the Train A valves CS-LCV-112B and CS-LCV-112D. The Train B cables are routed in barriered conduits in fire zone PAB-F-3B-Z. See additional CS system discussion on CS -LCV-112B, CS-LCV-112C, CS-P-2A and CS -P-2B in the General Area Analysis, Section B.1.g. This zone contains cables for CS-FCV-110A, -111A, -110B, -111B. Spurious opening of these valves in conjunction with spurious start of boric acid transfer pump or reactor makeup water pump may divert boric acid from the reactor coolant system affecting cold shutdown reactivity control, or result in an unplanned dilution affecting hot standby and cold shutdown reactivity control. The operators isolate the diversion flow by closing

CS-FCV-110B & -111B using the main control board control switches. The operators isolate the dilution flow by closing CS -LCV-112C using the main control board control switch. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-268 c) Service Water (SW) System This zone contains Train A valves SW -V15 and SW -V16 and cables for Train A valve SW -V4. Also contained in this zone are the redundant Train B valves SW -V17 and SW-V18 and cables for valve SW -V5. Redundant valves SW -V15 and SW -V17 are in the Safe Shutdown position. In addition, the circuit breaker for SW-V17 is administratively controlled off so the valve cannot spuriously close. If SW -V15 spuriously closes, SW-V17 is still open to provide the Train B PCCW heat exchanger cooling function. For conservatism, the operators will prevent further spurious operation by tripping the SW -V15 power supply breaker in the Train A switchgear room (Fire Area: CB -F-1A-A). Redundant diesel generator jacket water heat exchanger valves SW -V16 and SW-V18 are normally closed and are required to open for operation of the diesel generators.

De-energizing the solenoids will open the valves. If SW-V16 or SW -V18 spuriously closes, SW to the respective train DG would be isolated. The other train DG

would still be available. Also, a fire in this area does not cause a loss -of-offsite power. To prevent further spurious operation, the operators will trip the valves ' power supply breakers in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The Train A cables for valve SW -V4 are routed in trays and conduit. The trays and conduit are a minimum of 10 ' above floor Elevation 53 '-0". The Train B cables for valve SW-V5 are routed in barriered conduits. The Train A and Train B raceways are separated by greater than 25 '. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-269 3) Summary For the CC system above, the safe shutdown requirements are satisfied. For the CS system above, the routing of the Train B cables in conduit with a one -hour, fire rated barrier in another fire zone and considering the low combustibles loading in the zone, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III G.2.c, "in addition to one (1) hour fire barrier, an automatic fire suppression system shall be installed ", has been approved. Also, the capability to isolate the boric acid diversion flow and the dilution flow using the main control board control switches satisfies the safe shutdown requirements. For the SW system above, the routing of the Train B cables in a conduit with a one -hour, fire -rated barrier; the spatial separation; the disabling capabilities in another fire area; and considering the low combustibles loading in the zone, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R, Paragraph III G.2.c, "in addition to one (1) hour fire barrier, an automatic fire suppression system shall be installed ", has bee n approved.

1) Specific Zone Analysis This zone at Elevation 53

'-0" of the PAB is bounded by concrete floor, ceiling and walls (South, East and West) and is contiguous to fire zone PAB -F-3A-Z to the North. The northern boundary consists of a full height partition wall. There are penetrations for ducts and pipes to other fire zones. The zone is approximately 88 ' long by 75 ' wide by 26 ' high with a floor area of 6500 sq. ft. and a volume of 168,200 cu. ft.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-270 Combustibles are limited to 71 pounds of plastic (fiberglass ladders) for a fire loading of 923,000 Btu, 0.5 gallon of oil for a fire loading of 75,000 Btu, 50 pounds of Class A material for a fire loading of 400,000 Btu for a total fire loading of 1602 Btu per sq. ft. of floor area. See "Fire Protection Program Evaluation and Comparison to Branch Technical Position APCSB 9.5 -1 Appendix A" for the analysis of 6600 lbs. of charcoal in CAP-F-40. Detectors are provided throughout the zone.

2) System Analysis a) Primary Component Cooling Water (CC) System Redundant transmitters and cables for head tank level logic are in proximity. Failures in these transmitters or cables could initiate a spurious lo

-lo head tank level isolation signal. This in turn would result in closure of the PCCW containment isolation valves. These valves are only required when it is necessary to maintain containment habitable for containment entry to manually operate the RHR isolation valves and the SI accumulator isolation valves. The circuitry for these valves is not affected by a fire in this area; hence, they would be operable from the MCR. Therefore, the spurious operation of these transmitters will not prevent safe shutdown. b) Chemical and Volume Control (CS) System The redundant volume control tank isolation valves

CS-LCV-112B and CS -LCV-112C are located in the same fire area. The valves are in separate concrete cells with concrete walls and a solid controlled access door between them. There are no in situ combustibles or cables in trays in the cells. The cables for the Train B valve CS-LCV-112C are routed in barriered conduits. See additional CS system discussion on CS -LCV-112B, CS-LCV-112C, CS-P-2A and CS -P-2B in the General Area Analysis, Section B.1.g.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-271 This zone contains cables for the redundant RWST suction valves CS -LCV-112D and CS -LCV-112E. These cables are part of a circuit that will automatically open the opposite train RWST valve if a VCT valve is not full open (i.e., spuriously closes). Since the VCT valves do not spuriously close for a fi re in this zone, the automatic open circuit is not required. The automatic open circuit is supplied from a separate circuit, i.e., not the RWST MOV control circuit, so failure of these cables does not affect the ability to manually open the RWST valves as part of transferring charging pump suction from the VCT to the RWST. This zone contains cables for

CS-FCV-110A, -111A, -110B, -111B. Spurious opening of these valves in conjunction with spurious start of a boric acid transfer pump or reactor makeup water pump may divert boric acid from the reactor coolant system affecting cold shutdown reactivity control, or result in an unplanned dilution affecting hot standby and cold shutdown reactivity control. The operators isolate the diversion flow by closing CS-FCV-110B & -111B using the main control board control switches. The operators isolate the dilution flow by closing CS -LCV-112C using their main control board control switch.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-272 3) Summary For the CC system above, the safe shutdown requirements are satisfied. For the CS system above, the routing of the Train B cables in a one-hour, fire -rated barrier; the separation between the valves; the absence of in situ combustibles in the cells; and considering the low combustibles loading in the zone, provide acceptable fire protection and provide protection equivalent to the technical requirements of Appendix R. A deviation from Appendix R Paragraph III G.2.c, "in addition to 1 hour fire barrier, an automatic fire suppression system shall be installed ", has been approved. Also, the capability to isolate the boric acid diversion flow and the dilution flow using the main control board control switches satisfies the safe shutdown requirements. C. Evaluation Deviations from the Appendix R, Paragraph III.G.2 separation requirements exist in the Primary Auxiliary Building fire zones PAB -F-1A-Z, PAB-F-1J-Z, PAB-F-1K-Z, PAB-F-2A-Z, PAB-F-2B-Z, PAB-F-2C-Z, PAB-F-3A-Z and PAB-F-3B-Z. These deviations are justified based on the above analyses and our assertion that additional modifications would not enhance fire protection safety.

The redundant Train B safe shutdown cables are located in fire area DCT -F-3B-0 and other fire areas. The Appendix R separation requirements are satisfied.

2. PCCW Head Tank level Transmitters CC

-LT-2172-1, 2, 3; CC -LT-2272-1, 2, 3; CC-LT-2192-1, 2, 3, CC -LT-2292-1, 2, 3 Cables for the redundant head tank level transmitters are in proximity. Failures in these cables could initiate a spurious lo -lo-head tank level isolation signal. This in turn would result in closure of the PCCW containment isolation valves. These valves are only required when it is necessary to maintain containment habitable for containment entry to manually operate the RHR isolation valves and the SI accumulator isolation valves. The circuitry for these valves is not affected by a fire in this area; hence, they would be operable from the MCR. Therefore, the spurious operation of these transmitters will not prevent safe shutdown. The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-280 3. Component Cooling Water Pumps CC -P-11A, CC-P-11C and Component Cooling Water Containment Isolation Valves CC -V175, CC-V257 A fire could cause loss of all PCCW to containment. It should be noted, however, that these valves are required to remain operable only for containment entry when manual operation of the safety injection isolation valves SI -V3, SI-V17, SI-V32 and SI-V47 and the reactor coolant - RHR isolation valves RC -V22, RC-V23, RC-V87 and RC -V88 are required. Cables for these valves are not routed through this fire area; hence, the valves would be operable from the main control room or the RSS control panels and containment entry would not be required. The safe shutdown requirements are satisfied.

4. RHR Heat Exchanger Outlet Valves CC

-V145, CC-V272 Cables for redundant valves CC -V145 and CC -V272 are routed in proximity to one another. The valves are normally open to their shutdown cooling position and their position is inconsequential until the plant is cooled down to 350F and the RH system is placed in operation. At that time, it is necessary to assure that the valve supplying PCCW to the operational RH train is opened. This can be accomplished manually if required in the appropriate equipment vault. Manual operation can be delayed as much as 9 hours into the event. Therefore, no fire protection other than the existing separation is needed. The provision of a capability to position the valve outside the fire area satisfies the safe shutdown requirements.

5. Charging Pump Discharge Valve CS

-FCV-121 This zone contains cables in tray required for operation of Train A valves

CS-FCV-121, which provides one of the required hot standby charging flow paths. The redundant Train B SI-V139 cables are located in Fire Area DCT-F-3B-0. For cooldown, the operators will manually align the Train B charging pump discharge and bypass valves (CS -V219 and CS -V220) to the seal injection flow path and throttle the bypass valve as required. This operator action can be delayed for up to of 4 hours. The Appendix R separation and safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-281 6. Boric Acid Tank Level Transmitter CS -LT-102, CS-LT-106 This zone contains cables routed in tray for the redundant boric acid tank level transmitters CS -LT-102 and CS -LT-106. These tank levels are only required once cooldown has been initiated. Should both transmitter cables be damaged by a fire, the operators can utilize the Train B level transmitter CS -LT-7464 whose cable is not routed through this fire area. The indicator for this transmitter is located at the RSS panel in the Train B switchgear room (Fire Area: CB -F-1B-A). The provision of a redundant transmitter with its cable routed in another fire area satisfies the safe shutdown requirements.

7. Seal Injection Isolation Valves CS

-V154, CS-V158, CS-V162 and CS -V166 Under normal conditions, the seal injection isolation valves CS -V154, CS-V158, CS-V162 and CS -V166 are utilized for the seal injection flow path. Spurious closure of one of these valves will not prevent safe shutdown. The operators will prevent further spurious operations by tripping the power supply breakers in the Train A switchgear room (Fire Area: CB -F-1A-A). The safe shutdown requirements are satisfied.

8. RC Pump Seal Water Isolation Valve CS

-V167 Valve CS-V167 is a normally open valve which should remain open for safe shutdown. Spurious isolation of this Train A valve could result in loss of RC inventory through the upstream relief valve. This inventory is directed to the PRT and is therefore, non -recoverable. To preclude this loss of inventory, functionally redundant isolation capability is provided by the RC pump seal return lines by means of Train A valves CS -V10, CS-V28, CS-V44, and CS -V59. The cables, controls and equipment required for operation of valves CS -V10, CS-V28, CS-V44, and CS -V59, are not contained in this fire area. The Appendix R separation requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-282 9. BAT to Charging Pump Isolation Valve CS -V426 Valve CS-V426 is a normally closed valve which is opened to provide a path from the boric acid tanks to the charging pump suction. This path is required to begin cooldown. In the event that this valve is inoperable, the operators can provide a redundant path by manually positioning valves in the boric acid tank room (Fire Area: PAB -F-2B-Z). The operators can maintain the plant in hot standby for the time required to perform this manual action. The safe shutdown requirements are satisfied.

10. SI-CS Suction Cross Connection Valves CS

-V460, CS-V461, CS-V475 Valves CS -V460, CS-V461 and CS -V475 are located in proximity. Prior to beginning cooldown the normally closed CS -V460 and CS -V461 valves should remain closed or the functionally redundant valve CS -V475 should be closed. The isolation of this path will prevent loss of boric acid tank inventory to the RWST during cooldown. In the event of a spurious valve operation which renders this flow path open, the plant can be maintained in hot standby for as long as 4 hours. Should the operators desire to initiate the cooldown sooner than 4 hours, a gravity feed can be established from the boric acid tanks to the charging pumps. As the BAT head is lower than that required to return inventory to the RWST, there would be no loss of BAT inventory through this path and the position of these valves would be inconsequential. The safe shutdown requirements are satisfied.

-DP-35A, PAH-DP-36A, PAH-DP-35B, PAH-DP-36B Cables for outboard isolation dampers PAH -DP-35A and PAH -DP-36A and inboard isolation dampers PAH -DP-35B and PAH -DP-36B are routed in trays and conduits in proximity to one another. Under normal operation both outboard and both inboard dampers are open. If both outboard or both inboard dampers go closed, the Containment Enclosure Air Handling (EAH) system operates in recirculation mode. The normal and recirculation modes for EAH system operation both satisfy the safe shutdown function. If the outboard dampers and the inboard dampers operate independently such that either the supply or the exhaust path but not both are isolated, there could be an air flow problem in EAH system. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-283 Outboard dampers are powered from a single Train A power supply. Inboard dampers are powered from a single Train B power supply. The circuit design for the outboard and inboard dampers is such that a spurious signal in either or both circuits will cause both outboard and inboard dampers to operate together, either both open (normal mode) or both closed (recirculation mode). The safe shutdown requirements are satisfied.

12. RHR Isolation Valves RC

-V22, RC-V23, RC-V87, RC-V88 Cables for redundant valves are located in proximity. As the RHR isolation valves are permanently disabled in the closed position, failures in the cables cannot cause a spurious operation. Valves RC -V87 and RC -V88 are required to be opened for cooldown below 350F when the RH system is placed in operation. Should the cable damage be such that the valves cannot be operated from the MCR, the affected portion of the circuit can be isolated at the RSS panels in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A) and the valves repositioned for safe shutdown. The safe shutdown requirements are satisfied.

13. RHR Heat Exchanger Outlet Flow Control and Bypass Flow Control Valves RH-FCV-618, RH-HCV-606, RH-FCV-619, RH-HCV-607 Cables for the redundant flow control valves are routed in proximity. The RH-HCV-606 and RH

-HCV-607 valves are normally closed and are required to open whereas the RH -FCV-618 and RH -FCV-619 are normally open and are required to close. These valves are only required to operate when the RH system is placed in operation (cold shutdown). The valves have air operators controlled by dc solenoids. These solenoids when deenergized vent the air from the operators and cause the valves to fail to their safe shutdown position. In the event this positioning cannot be performed in the MCR, the operators will position these valves by tripping the power supply breakers in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-284 14. RH Pump to Cold Leg Isolation Valves RH -V14, RH-V26 Cables for redundant valves RH -V14 and RH -V26 are routed in proximity. These valves are normally open valves which are required to remain open for RH systems operation (cold shutdown). If one of the valves spuriously closes, the operators will prevent further spurious operation of these valves by tripping the power supply breakers in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). The safe shutdown requirements are satisfied.

15. RH Pump to Hot Leg Isolation Valves RH

-V70, RH-V32 Cables for redundant valves RH -V70 and RH -V32 are routed in proximity. These valves are normally closed valves which are required to remain closed for RH system operation (cold shutdown). If one of the valves spuriously opens, the operators will prevent further spurious operation of these valves by tripping the power supply breakers in the Train A and Train B switchgear rooms (Fire Areas: CB-F-1A-A and CB-F-1B-A). The safe shutdown requirements are satisfied.

16. RH Heat Exchanger to CS/SI Pump Isolation Valves RH-V35, RH-V36 Cables for the redundant valves RH

-V35 and RH -V36 are routed in proximity. Valves RH -V35 and RH -V36 are normally closed and their position is inconsequential until the plant is cooled down to 350F and the RH system is placed in operation. At that time it is necessary to assure that the valves remain closed. Should one of the valves open spuriously the operators can disable its power supply in either the Train A or Train B switchgear rooms (Fire Areas: CB-F-1A-A or CB-F-1B-A) and manually reposition the valves located in the equipment vaults (Fire Zone RHR -F-4B-Z or RHR-F-2A-Z). Manual operation of the valves can be delayed as much as 9 hours into the event. Therefore, no fire protection other than the existing separation is needed. The provision of a capability to mitigate the spurious operation of the valves outside the fire area satisfies the safe shutdown requirements.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-285 17. Containment Pressure Transmitters SI -PT-936, SI-PT-937 Redundant channels of containment pressure cables are located in proximity. Spurious operation of these channels will initiate containment spray and containment isolation Phase B. The operators will have the capability to terminate these protective actions by use of manual reset switches. All ESF equipment which has been started will be tripped and locked out. To preclude further spurious operations, the operators will disable the engineered safety features logic cabinets in the Train A and Train B switchgear rooms (Fire Areas: CB-F-1A-A and CB-F-1B-A). The provision of a capability to mitigate the spurious operation of the pressure transmitters outside the fire area satisfies the safe shutdown requirements.

18. Volume Control Tank Isolation Valve CS

-LCV-112B and Charging Pump CS-P-2A & CS-P-2B Volume control tank (VCT) isolation valves CS -LCV-112B & -112C are normally open to provide a suction path from the VCT to the normally operating charging pump (CS -P-2A or -2B). These valves must stay open until RWST valve CS-LCV-112D or -112E is manually opened to provide a charging pump suction path from the RWST, or the boric acid tanks are manually aligned as a charging pump suction source. Spurious closure of a VCT isolation valve caused by a hot short would interrupt suction flow to the operating charging pump

causing it to be damaged. If the standby charging pump has cables in the same area then its operation can also be degraded. The result would be no charging system flow. Since this fire area contains cables for CS -LCV-112B and CS -P-2A, this condition is potentially applicable for the system alignment with CS -P-2A the standby pump and CS -P-2B the operating pump. The CS-LCV-112B circuit design prevents spurious valve closure from hot shorts as follows. The field cable conductors for the motor control center (MCC) contactor close coil circuit are in different cables than the 120 V "hot" circuit conductors eliminating the hot short failure mode within the cables. Cable-to-cable hot shorts need not be postulated for thermoset cable insulation as used at Seabrook. Since CS -LCV-112B will not spuriously close, CS -P-2B as the operating charging pump will not be damaged. Since charging flow is available, the safe shutdown requirements are satisfied.

Boration/Dilution Flow Control Valves, CS -FCV-110A, -111A, -110B, -111B This area contains cables for CS -FCV-110A, -111A, -110B, -111B. Spurious opening of these valves in conjunction with spurious start of a boric acid transfer pump or reactor makeup water pump may divert boric acid from the reactor coolant system affecting cold shutdown reacivity control, or result in an unplanned dilution affecting hot standby and cold shutdown reactivity control. The operators isolate the diversion flow by closing CS -FCV-110B and -111B using the main control board control switches. The operators isolate the dilution flow by closing CS -LCV-112C using the main control broad switch. The safe shutdown requirements are satisfied. C.

SI-CS Suction Cross Connection Valves CS -V461, CS-V475 Valves CS -V461 and CS-V475 are located in proximity. Prior to beginning cool down the normally closed valve CS -V461 should remain closed or the functionally redundant valve CS -V475 should be closed. The isolation of this path will prevent loss of boric acid tank inventory to the RWST during cooldown. In the event of a spurious valve operation, which renders this flow path open, the plant can be maintained in hot standby for as long as 4 hours. Should this area be inaccessible due to the fire or should the operators desire to initiate the cooldown sooner than 4 hours, a gravity feed can be established from the boric acid tanks to the charging pumps. As the BAT head is lower than that required to return inventory to the RWST, there would be no loss of BAT inventory through this path and the position of these valves would be inconsequential. The safe shutdown requirements are satisfied.

The operator will manually trip the switchgear in the non -essential switchgear room (Fire Area: NES-F-1A-Z). Pressurizer heaters C, D and control group control power could be lost. If the heaters require tripping, an operator will manually trip them in the Train A switchgear room (Fire Area: CB -F-1A-A). Alternatively, the operator can reduce pressure by operating a PORV. Redundant heaters are available with control power from the emergency DC buses. The safe shutdown requirements are satisfied.

4. Electrical Distribution Emergency (EDE) System (4160 Swgr. E5, E6; Control Panels SY

-CP-84, 85, 86, 87, and 460V MCC E523) Redundant equipment and cables for the 4160 switchgear are located in the same fire area. A short circuit in this equipment or cables can cause a trip of the 4160V emergency switchgear E5 and E6 incoming line breakers from the UAT and RAT, resulting in loss of the offsite power supply. Loss of the offsite power supply will require starting of the diesel generators. The emergency buses will be powered from the diesel generators. This is the design base for safe shutdown. The safe shutdown requirements are satisfied. For the 460V MCC 's all equipment and cables are Train A, the functionally redundant Train B cables and equipment are located in fire area CB -F-1B-A, separated from this area by a 3 -hour fire wall. The Appendix R separation requirements are satisfied.

Instrument Air (IA) System Redundant equipment and cables for instrument air dryers are located in the same fire area. Dryers IA -SKD-18A and IA -SKD-18B provide instrument air for the primary component cooling water system containment isolation valves, Train A and Train B switchgear room dampers CBA -DP-24A, B, C, D, E, F, and MCR dampers CBA-DP-26A and CBA-DP-26B. Component cooling water to containment is required to maintain containment habitability. For a fire in this area, containment entry is not required as operators have the capability to operate safety injection accumulator isolation valves SI -V3, SI-V17, SI-V32 and SI -V47 and RHR isolation valves RC -V22, RC-V23, RC-V87 and RC -V88 from the main control room (Fire Area: CB-F-3A-A) or the RSS control panels (Fire Areas: CB -F-1A-A and CB-F-1B-A), separated from this area by a 3 -hour fire wall. The operators have the capability to manually position the Main Control Room air conditioning condenser units face and bypass dampers in the Diesel Generator Building HVAC equipment area (Fire Areas DG -F-3A-Z & DG-F-3B-Z). As these dampers fail "as is", this action would only be required to maintain long term habitability required by 9 hours into the event. Therefore, the air dryers are not required for safe shutdown for a fire in this area. The safe shutdown requirements are satisfied.

Service Air (SA) System Redundant equipment and cables for the service air system and secondary component cooling system with its tie -in to the fire protection system are located in the same fire area. Compressor skids SA -SKD-137A and SA -SKD-137B and their associated equipment provide instrument air for the primary component cooling water system containment isolation valves, and MCR dampers CBA -DP-26A and CBA-DP-26B. Component cooling water to containment is required to maintain containment habitability. For a fire in this area, containment entry is not required as operators have the capability to operate safety injection accumulator isolation valves

SI-V3, SI-V17, SI-V32 and SI -V47 and RHR isolation valves RC -V22, RC-V23, RC-V87 and RC -V88 from the main control room (Fire Areas: CB -F-3A-A) or the RSS control panels (Fire Areas: CB -F-1A-A and CB-F-1B-A), separated from this area by a 3 -hour fire wall. The operators have the capability to manually position the MCR dampers in the Control Room HVAC Room (Fire Area: CB -F-3B-A), separated from this area by a 3 -hour fire wall. The operators have the capability to manually position the switchgear room dampers in the control building mechanical equipment rooms (Fire Areas: CB -F-2B-A and CB-F-2C-A). As the Train A and Train B switchgear room intake and recirculation dampers fail "as is" and the exhaust damper fails open, this action would only be required to maintain long term habitability required by 9 hours into the event. Therefore, the SA system is not required for safe shutdown for a fire in this area. The safe shutdown requirements are satisfied. C. Evaluation The safe shutdown requirements and Appendix R separation requirements are satisfied.

Redundant equipment is located in fire area EFW -F-1A. Also RC pump switchgear control power is lost. When the RCP 's are required to be tripped (during cooldown) the operator will manually trip them in the non -essential switchgear room (Fire Area: NES -F-1A-Z). Pressurizer Heaters C, D, and control group control power will be lost. An operator, if the heaters require tripping, will do so in the Train A switchgear room (Fire Area: CB -F-1A-A).

Analysis Redundant valves CS -LCV-112D and CS -LCV-112E are located in the same fire area. The cables for VCT isolation valves CS -LCV-112B and CS -LCV-112C, are also located in this fire area. These are normally open valves. A fire in this area will prevent opening the normally closed RWST to charging pump isolation valves from the control room. The normally open VCT isolation valves may experience a loss of control power but can not spuriously close as described below. A fire in this area does not affect the normal charging, letdown, and boric acid makeup functions so safe shutdown can be achieved and maintained using a charging pump aligned to the VCT through CS -LCV-112 B & -112C. The RWST is not needed for this normal shutdown so the inability to open CS -LCV-112D & -112E does not affect safe shutdown. If there was a need to use the RWST, the RWST valves could be manually opened, and the VCT isolation valves could be closed from the RSS panels or manually closed. Volume control tank (VCT) isolation valves CS -LCV-112B & -112C are normally open to provide a suction path from the VCT to the normally operating charging pump (CS-P-2A or -2B). These valves must stay open to provide a charging pump suction path from the VCT. Spurious closure of a VCT isolation valve caused by a hot short would interrupt suction flow to the operating charging pump causing it to be damaged. If the standby charging pump has cables in the same area then its operation can also be degraded. The result would be no charging system flow. Since this fire area does not contain cables for CS -P-2A or CS-P-2B, this condition is not applicable to this fire zone.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 13 Section 3.2 Page 3.2-311 Furthermore, the CS -LCV-112B and -112C circuit design prevents spurious valve closure from hot shorts as follows. The field cable conductors for the motor control center (MCC) contactor close coil circuit are in different cables from the 120 V "hot" circuit conductors eliminating the hot short failure mode within the cables. Cable -to-cable hot shorts need not be postulated for thermoset cable insulation as used at Seabrook. Since

CS-LCV-112B and -112C will not spuriously close, CS-P-2A or -2B as the operating charging pump will not be damaged. C. Evaluation The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 14 Section 3.3 Page 3.3-1 3.3 ALTERNATIVE SAFE SHUTDOWN USING REMOTE SAFE SHUTDOWN FACILITIES 3.3.1 General Remote safe shutdown (RSS) is a design feature which allows plant shutdown from locations other than the main control room in the event of a fire or other condition which requires evacuation of the main control room. The fire areas of concern are the main control room, control room HVAC room, and the cable spreading room. Remote safe shutdown contains the necessary complement of systems and equipment required to satisfy the performance goals delineated in Appendix R, Paragraph III.L.2. Technical Specification (T/S) 3/4.3.3.5 requires surveillance testing of selected equipment used for safe shutdown from outside the Control Room at Remote Safe Shutdown (RSS) locations. The required equipment is listed in Table 3.3 -9. The selection criteria for the Transfer Switch/Control Circuit portion of the table is the primary equipment which has remote/local selector switches and is required to perform the reactor coolant system inventory and pressure control, reactivity control, and decay heat removal functions to achieve and maintain hot standby. For Appendix R shutdown, only one train of equipment (safety or non -safety related) is required; redundancy is not a requirement. Seabrook is a hot standby safe shutdown design basis plant (see UFSAR Section 5.4.7.2.i). Support equipment, and equipment required only to achieve and maintain cold shutdown, are not required to be included in the T/S table. Process monitoring instruments also have surveillance requirements. 3.3.2 Safe Shutdown Control Locations Normally safe shutdown will be accomplished from the main control room, utilizing the safe shutdown equipment along with other equipment which may be available to the operators. Upon detection of a fire, the fire brigade will be dispatched to the affected area and a determination will be made as to the severity of the fire. If it is determined that the fire has a potential for impacting safe shutdown from the main control room, the operators will proceed with a planned evacuation of the main control room and manning of the Train B remote safe shutdown control panel (MM-CP-108B) and man the following remote safe shutdown (RSS) facilities as necessary:

a. Train B Switchgear Room (Switchgear E6, and various Unit Substations, Motor Control Centers (MCC) and Distribution Panels) and RSS Aux Panel in Electrical Tunnel B. b. Train A Switchgear Room (MM

-CP-108A, Switchgear E5, and various Unit Substations, Motor Control Centers (MCC), and Distribution Panels) and RSS Aux Panel in Electrical Tunnel A .

" refers to an action taken after receipt of a valid fire alarm in the main control room. The term "expeditious action " or "expeditiously " refers to an action taken quickly upon entry into the applicable safe shutdown procedure. These type actions are considered to be completed prior to a spurious operation of the equipment operated by the prompt and expeditious actions. Therefore, no associated timing calculation is required for these actions. 3.3.3 Safe Shutdown Functions for Hot Standby The following are equipment necessary for Hot Standby:

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 14 Section 3.3 Page 3.3-3 3.3.3.1 Reactor Coolant (RC) Inventory and Pressure Control To compensate for miscellaneous RC system leakage, RC pump seal leakage and cooldown volume shrink, portions of the chemical and volume control (CS) system including centrifugal charging pumps, boric acid transfer pumps, and a borated water supply, either the refueling water storage tank (RWST) or the boric acid tanks (BAT) are used. The injection path to the RC system will be either through the seal injection flow path or the high head injection flow path. The preferred seal injection path requires that a flow control valve (CS -FCV-121) and that a minimum of two of the four seal injection valves (CS -V154, CS-V158, CS-V162 or CS -V166) be operable. Additionally, the normal charging flow to the RC system is isolated. This can be accomplished by temporarily stopping a charging pump to prevent overfill of the pressurizer. It can also be accomplished by use of any one of two functionally redundant but non -credited valves (CS -V142 or CS -V143). Should the seal injection path not be operable e.g., due to spurious closure of a flowpath valve (CS-FCV-121), the high head injection flow path (SI -V138 or SI -V139) can be utilized initially to maintain hot standby by batch charging from the RWST to maintain pressurizer level. During cooldown as RC system pressure decreases, it is necessary to provide a flow restricted path to prevent charging pump cavitation. This is due to the limited flow capability from the BAT. If the high head injection path cannot be isolated at this time and/or if the flow controlled path through CS -FCV-121 is not operable, a capability is provided to manually align and throttle the charging pumps to the seal injection flow paths. The necessary operator actions and valve alignments are unique for each fire area where these flow paths are affected and are described in the analysis for each area. RC pump seal cooling is provided by a redundant thermal barrier cooling system. Should the redundant thermal barrier system not be available, the seals will be cooled by the seal injection capability. A control room or cable spreading room fire can result in a temporary loss of all cooling to the RCP seals. The operator action to accomplish restoration of cooling to the seals is to restore power to an emergency bus, restart of a thermal barrier cooling pump and a CC water pump. Then, a charging pump and SW pump are started for long term seal cooling via seal cooling, as well as inventory control. The operator action to restore RCP seal cooling is accomplished prior to the time that there would be potential damage to the seals. The reactor coolant pumps (RCPs) are stopped from the main control board prior to evacuating the main control room. Circuit analysis shows that the RCPs can not spuriously restart due to fire -induced cable damage. The RC system pressure is controlled by use of a portion of the RC system which includes the pressurizer heaters (Group A and B) to increase pressure and the pressurizer power operated relief

valves (PORV) which depressurize the RC system by discharging reactor coolant fluid to the pressurizer relief tank (PRT).

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 14 Section 3.3 Page 3.3-4 Considering worst case scenarios for spurious actuation of affected equipment, the required times for operator actions regarding RC inventory and pressure control for safe shutdown from the remote safe shutdown facilities are provided below: Action Time Close PORV block valve Prompt Open the RWST outlet valves Prompt Place the standby charging pump in pull -to-lock Prompt Restore RCP seal cooling 9.9 to 19.8 minutes, depending on the highest RCP seal rate Trip RCPs 10 minutes Restore cooling to charging pump oil cooler

9.6 minutes

Isolate letdown 15 minutes Swap charging pump suction from VCT to RWST 15.4 minutes. Should SI -V138, SI-V139, or CS -HCV-182 spuriously open, this action must be completed no later than 5.0 minutes following letdown line isolation. Restore SW to emergency diesel generators 17.6 minutes Open a PORV to reduce pressurizer pressure in the event of spurious pressurizer heater operation or trip pressurizer heaters 23 minutes Start a charging pump, or open a high head safety injection valve SI -V-138 or SI -V-139 if normal charging pump path is not available 31.1 minutes Isolate charging flow, except for seal injection 35.4 minutes Trip spuriously operating containment building spray pumps 46 minutes Trip spuriously operating SI pump

<4 hours, prior to commencement of plant cooldown Align BAT for makeup source
<4 hours, prior to commencement of plant cooldown 3.3.3.2  Reactivity Control Reactivity for hot standby at normal operating temperature (NOT) is provided by insertion of the control rods. Reactivity conditions required for cooldown and maintaining cold shutdown are provided by a portion of the chemical and volume control (CS) system which includes a centrifugal charging pump taking suction from the BAT

's. During cooldown, the borated source must be the BAT volume until expended to at least the point that the volume injected or a boron sample demonstrates that sufficient shutdown margin for cold shutdown has been achieved, at which time the RWST would be aligned. The credited path for boration is gravity feed with the RWSP isolated. The boric acid transfer pumps can be used if available. Considering worst case scenarios for spurious actuation of affected equipment, the required times for operator actions regarding reactivity control for safe shutdown from the remote safe shutdown facilities are provided below: Action Time Trip the Reactor Expeditiously Provide borated water from the BATs, via boric acid transfer pump or gravity feed.

<4 hours, prior to commencement of plant cooldown Isolate boric acid flow diversion path.
<4 hours, prior to commencement of plant cooldown

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 14 Section 3.3 Page 3.3-6 3.3.3.3 Decay Heat Removal The reactor coolant (RC) system temperature is controlled by use of portions of the feedwater (FW) system and the main steam (MS) system. The main steam safety/relief valves will maintain a heat dump capability. The steam generator water inventory is controlled by operating the motor driven emergency feedwater pump and associated emergency feedwater control valves. Inventory for the emergency feedwater is from the condensate storage tank. Long term water capability exists using a temporary connection between the suction of the emergency feed pumps and the fire protection system but is not required to meet Appendix R requirements. To assure main steam system integrity the MSIV 's and MSIV bypass are maintained closed. The MSIV bypass valves are normally locked closed and depowered with breakers locked open to preclude spurious opening. Decay heat transfer is made possible by natural convection flow in the RC System. Considering worst case scenarios for spurious actuation of affected equipment, the required times for operator actions regarding decay heat removal for safe shutdown from the remote safe shutdown facilities are provided below: Action Time Isolate MSIVs Expeditiously following a reactor trip Place the mode selector switches for the ASDVs to the closed position Prompt Gain Control of excessive Emergency Feedwater Flow 20 minutes Start motor driven EFW pump to preclude steam generator dry out 39 minutes Time allotted for operator actions to preclude emptying CO tank to accommodate RHR Cut -in, and ultimately achieve cold safe shutdown within 72 hours 9 hours; 4 hours at hot standby plus

5 hours cooldown to RHR Cut -in 3.3.3.4 Process Monitoring Instrumentation is provided at the Train B remote safe shutdown control panel for monitoring the following process variables:

a. Steam generator emergency feedwater flow

b. Steam generator wide-range level Note that other instrumentation is provided at the Train A remote safe shutdown control panel but is not credited for Appendix R fire safe shutdown.

3.3.3.5 Service Water The service water system will supply cooling water to the primary component cooling water system, diesel generators, and if required, fire protection system. Service water supply will be from the service water pumps taking suction from the tunnels to the ocean. Section 3.3.3.1 provides the required times for operator actions, based on worst case scenarios for spurious actuation. 3.3.3.6 Primary Component Cooling Water (CC) The CC system is utilized to maintain cooling water to the charging pumps, RH pumps, RH heat exchangers, and reactor coolant pumps (RCP) thermal barrier heat exchanger. The PCCW pumps, temperature control valves, and RCP thermal barrier cooling pumps are necessary for system operations. Section 3.3.3.1 provides the required times for operator actions, based on worst case scenarios for spurious actuation.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 14 Section 3.3 Page 3.3-8 3.3.3.7 Sampling Sampling of the reactor coolant system is not required at hot standby and cold shutdown conditions since make -up during cool -down will only be provided to the RCS from the boric acid tanks (two) which are maintained at 4 wt% boric acid. During all phases of cool -down, the core will be maintained to the shutdown margin greater than or equal to the limit specified in the Core Operating Limits Report (COLR). 3.3.3.8 Diesel-Generator Building Air Handling (DAH) The DAH system is utilized to maintain long -term habitability and equipment protection for the diesel-generator rooms. The DAH system includes the fans and dampers for air handling in these areas. 3.3.3.9 Containment Enclosure Air Handling (EAH) The EAH system is utilized to maintain long-term habitability of the mechanical penetration area, and provide equipment cooling in the charging pump rooms, and the hydrogen analyzer and electrical room. The EAH system includes the coolers, fans, and dampers required for air handling in these areas. 3.3.3.10 Emergency Feedwater Pumphouse Air Handling (EPA) The EPA system is utilized to maintain long -term habitability and equipment protection in the emergency feedwater pump building. The EPA system includes the fans and dampers required for air handling in this area. 3.3.3.11 Primary Auxiliary Building Air Handling (PAH) Portions of the PAH system are utilized to maintain long -term habitability and equipment protection in the PCCW area of the primary auxiliary building. The PAH system includes the fans and dampers required for ventilation in this area. 3.3.3.12 Service Water Air Handling (SWA) Portions of the SWA system are utilized for equipment protection in the SW pump house electrical control rooms. The SWA system includes the fans and dampers required for air handling in these areas. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 14 Section 3.3 Page 3.3-9 3.3.3.13 Electrical Distribution Emergency (EDE) Portions of the EDE system are required to power the various pumps, fans, valves, etc. required for safe shutdown. Included in the EDE system are the 4160 Volt ac emergency switchgear, 460 Volt ac emergency unit substations and motor control centers, the uninterruptible power supplies, 120 Volt ac vital distribution panels, 125 Volt dc batteries, battery chargers, and 125 Volt dc distribution panels. 3.3.3.14 Diesel-Generators (DG) The diesel -generators provide power to the electrical distribution emergency system upon loss of off-site power. The DG system includes the diesel, generators, control panels, engine -driven auxiliaries, fuel oil transfer pumps, starting air compressors and backup operating air compressors. 3.3.3.15 Safeguard Actuation System The safeguard actuation system could be actuated. A portion of this system is used to deactivate the system for recovery. 3.3.3.16 Communication The Gaitronics or radio systems are used to announce the fire event, dispatch the fire brigade, and to dispatch an NSO to perform local actions in the emergency diesel generator rooms. The Gaitronics system is also used to provide a fire alarm. Face -to-face communications is used to dispatch a control room operator (CRO) to the Train B switchgear room to perform local actions. A sound powered telephone loop (SPC) is provided for the CRO and NSO to communicate between the switchgear and the diesel generator rooms. Headsets or handsets are stored at these RSS locations for operator use. All actions required to achieve and maintain hot standby are taken in these areas. When field actions are required to commence cooldown, and achieve and maintain cold shutdown, an operator would: a) be dispatched to take the required action, b) go to the field and take the action, and c) then return and report the action completed. The RSS SPC loop also includes two SPC jacks in the RHR equipment vaults. Radios and Gaitronics are not credited but would be used as additional means of communications, if not damaged by the fire. 3.3.4 Safe Shutdown Functions for Cooldown The following equipment in addition to that which is listed in Section 3.3.3 are necessary for cooldown.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 14 Section 3.3 Page 3.3-10 3.3.4.1 Decay Heat Removal In addition to equipment discussed in Section 3.3.3.3, the steam generator atmospheric relief valves will be used for cooldown until the residual heat removal (RH) system can be used. The residual heat removal system will be the long term heat sink at the end of cooldown. An RH pump will be operated along with various control, manual and motor operated valves. 3.3.4.2 Sample System For cold shutdown, the operators will draw a manual sample from RH system to verify boron concentration before li ne-up to RCS. The operator will use manual valves in RH system. 3.3.5 Initial Operator Actions Remote safe shutdown procedures will require that prior to main control room evacuation the reactor, the main steam isolation valves, and the reactor coolant pumps be tripped, thus establishing a hot standby condition. Closure of the pressurizer PORV 's block valves, placing the switches for the ASDVs to the closed position, placing the standby centrifugal charging pump in pull -to-lock, and opening the RWST outlet valves to the charging pump suction will be accomplished from the main control board after alarm confirmation (promptly) to prevent over cooling situations from either the primary or secondary side of the plant and ensuring proper RCS inventory control. Additionally, capabilities to trip the four MSIV 'S, the four RCP 's and the pressurizer PORV 's and atmospheric relief valves exist outside the main control room. After a confirmed fire alarm for a main control room or cable spreading room fire, a control room operator (CRO) and nuclear systems operator (NSO) are dispatched to the Train B switchgear and emergency diesel generator rooms to take actions as directed by procedure. In the time interval required for the operators to evacuate the main control room and man the RSS facilities, decay heat removal is accomplished automatically by the steam generator safety valves. No other function is required initially to maintain a decay heat sink for the reactor. Upon arrival at the RSS facilities, the operators will transfer control capability to the RSS facility by means of "Remote-Local" selector switches at the RSS locations and take the actions necessary to maintain control of the RCS inventory and pressure, and decay heat removal functions within the time frames described in sections 3.3.3.1 and 3.3.3.3. Control of the Train B Diesel Generator will be taken and if a Loss of Offsite Power (LOOP) occurs, clear and load EDE -SWG-6 to support safe shutdown. The operators will also trip the power supplies for engineered safety features actuation system (ESFAS) logic and cooling tower actuation logic to prevent inadvertent activation of these functions. The operators will then disable (trip power supply breakers) all equipment which is properly positioned in its safe shutdown position. Any additional recovery actions needed to maintain hot standby or to start a cooldown will be completed if inadvertent safeguard operation, tower actuation or "HOT SHORT " actuation occurs.

However, analysis can be also provided to justify not listing components and cables in Appendix III. The tables provide the following requested information for each equipment listed: a) A column which notes whether the equipment is required for hot standby or cold shutdown. b) A column which defines each equipment 's location by fire zone/area. c) A column which defines each equipment 's redundant counterpart. d) A column which lists each equipment 's essential cabling. e) The table also delineates the following additional information:

3) Power Supply 4) Electrical Node Number

5) Supporting Control and Instrumentation Equipment

6) Electrical Schematic Drawing No.

7) Electrical Cable Schematic Drawing No.

8) Supporting Systems

9) Remarks Separate tables are furnished for each of the safe shutdown functions. In several instances a safe shutdown function requires components from several systems to perform its safe shutdown function.

Appendix R Section III.L requires that only one train of equipment necessary to achieve and maintain hot standby must be available from alternate or dedicated RSS shutdown facilities. Redundancy is not required. Equipment required to achieve and maintain cold shutdown can be repaired within 72 hours. For Seabrook, the preferred RSS shutdown equipment is Train B. The

Train B RSS equipment with R/L selector and control switches have redundant control circuit fuses. This ensures that the local control circuit will still be operable in case the MCR control circuit blows the circuit fuse before control is transferred to local. For conservatism, redundant Train A equipment is typically listed in the RSS equipment lists in Appendix III, for example, both the Train A and the Train B charging pumps are listed whereas only one (Train B) is required to provide the safe shutdown function. This Train A equipment is desired, but not required, for safe shutdown. In some cases the Train A equipment is not listed just for conservative redundancy but is actually required for safe shutdown, for example, the SI accumulator isolation valves where there are two Train A and two Train B required valves. In order to simplify the tabulation, the following are not listed: manual valves in the process flow path; mechanical check valves which provide a Safe Shutdown system boundary; normally closed manual valves which provide a Safe Shutdown system boundary; mechanical relief valves; and root valves on small instrument lines. The review of these valves is documented by the marked P & I Diagrams. Tables are provided for the following functions which satisfy the performance goals stated in Appendix R, Paragraph III.L.2 SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 14 Section 3.3 Page 3.3-14 Function Table No. Decay Heat Removal 3.1.3.1 Reactor Coolant Inventory and Pressure Control 3.1.3.2 Reactivity Control 3.1.3.3 Process Monitoring 3.1.3.4 Safeguard Actuation System 3.1.3.5 Cold Shutdown 3.1.3.6 Service Water 3.1.3.7 Primary Component Cooling Water 3.1.3.8 (Deleted) 3.1.3.9 Control Building Air Handling 3.1.3.10 Diesel Generator Building Air Handling 3.1.3.11 Containment Enclosure Air Handling 3.1.3.12 Emergency Feedwater Pumphouse Air Handling 3.1.3.13 Primary Auxiliary Building Air Handling 3.1.3.14 Service Water Air Handling 3.1.3.15 (Deleted) 3.1.3.16 Electrical Distribution Emergency 3.1.3.17 Diesel Generators 3.1.3.18 Communication 3.1.3.19 3.3.9 Analysis and Evaluation of Fire Areas An evaluation is provided as to whether the Appendix R requirements or safe shutdown requirement are satisfied.

Containment Enclosure Isolation Damper, PAH -DP-35A, PAH-DP-36A, PAH-DP-35B, PAH-DP-36B Cables for outboard isolation dampers PAH -DP-35A and PAH -DP-36A and inboard isolation dampers PAH -DP-35B and PAH -DP-36B are routed in trays and conduits in proximity to one another. Under normal operation both outboard and both inboard dampers are open. If both outboard or both inboard dampers go closed, the Containment Enclosure Air Handling (EAH) system operates in recirculation mode. The normal and recirculation modes for EAH system operation both satisfy the safe shutdown function. If the outboard dampers and the inboard dampers operate independently such that either the supply or the exhaust path but not both are isolated, there could be an air flow problem in EAH system. Outboard dampers are powered from a single Train A power supply. Inboard dampers are powered from a single Train B power supply. The circuit design for the outboard and inboard dampers is such that a spurious signal in either or both circuits will cause both outboard and inboard dampers to operate together, either both open (normal mode) or both closed (recirculation mode). The safe shutdown requirements are satisfied.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 9 Section 3.4 Page 3.4-1 3.4 ALTERNATIVE SAFE SHUTDOWN - EMERGENCY FEEDWATER PUMPHOUSE FIRE A fire in this area disables both emergency feedwater (EFW) pumps, associated EFW flow control valves, and related instrumentation. An immediate plant trip in response to this fire event is not desirable since this would place a demand on the EFW system which may not be available. Instead, plant operation will be maintained stable at 100% power conditions using the normal feedwater system while the fire event is assessed and appropriate mitigating actions are determined. The plant will not be perturbed by any action, including a power change, that might result in a plant trip and demand on the EFW system. If it is determined that plant shutdown is warranted, th en normal procedures will be used eliminating an EFW system demand. This approach is consistent with the Technical Specification 3/4.7.1.2 Bases. Plant shutdown using normal procedures does not require use of the EFW system so the time critical operator action response times related to the EFW system do not apply (see Section 3.2.2.3) for this fire area. If an immediate plant shutdown was required, then the startup feedwater pump (SUFP) would be used to provide the EFW function. Since both EFW trains are disabled by a fire in this area, this is considered an alternate shutdown capability area. Safe shutdown would be controlled from the main control room. Since this is not the preferred response, immediate plant shutdown is considered a beyond design basis condition analyzed for defense in depth. If the EFW flow control valves are disabled, then the EFW pumps may have to be tripped to control excessive EFW flow. The SUFP and its valves can provide throttled flow to prevent overfill/over cooling conditions. Since this is a beyond design basis, defense in depth, response, the time critical operator action response times related to the EFW system do not apply for this fire area. The following analysis evaluates the beyond design bases response of shutdown controlled from the main control room with an immediate plant trip using the SUFP to provide the EFW function. Plant shutdown using normal procedures does not require use of equipment in this fire area so no further analysis of normal shutdown is required. 3.4.1 Main Control Room Safe Shutdown Safe shutdown will be accomplished with control from the main control room, utilizing the safe shutdown equipment in the following locations:

a. Non-Essential Switchgear Area

b. Condensate Storage Tank Valve Room (CST)

c. Train A Switchgear Room

d. Train B Switchgear Room

e. Turbine Building SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 9 Section 3.4 Page 3.4-2 Actions required in the additional areas would be to realign the suction of the startup feedpump; realign the power supply of the startup feedpump from Bus ED

-SWG-4 to Bus EDE -SWG-5 (if offsite power is not available and not already aligned to Bus EDE-SWG-5); bypass the startup feedpump low suction pressure trip (prior to commencing cooldown) and trip the power supply breakers for the feedwater flow control valves. Safe shutdown will then be performed from the main control room. 3.4.2 Safe Shutdown Equipment List Tables that list all equipment, including instrumentation and vital support systems equipment, required to achieve hot standby and cold shutdown are provided in Appendix III. The tables provide the following requested information for each equipment listed.

a. A column which notes whether the equipment is required for hot standby and cold shutdown.

Analysis With the exception of the systems/equipment discussed below, a fire in this area will only affect the Train B safe shutdown equipment and cables. The redundant Train A safe shutdown equipment and cables are located in other fire areas. Additional details on the fire protection measures and physical separation for this fire area are contained in Tabulation 3.2.7.48. Redundant emergency feedwater flow control valves and associated flow transmitters which are part of the alternative shutdown capability are located in the fire area. These valves are normally open valves and remain open for the initial phases of safe shutdown. Only two steam generators are required to satisfy the safe shutdown requirements: hence, only two valves on each of two lines need to be disabled (e.g., FW -FV-4214A, FW-FV-4214B, FW -FV-4224A and FW -FV-4224B). The operators will prevent additional spurious operations by tripping the power supply breakers for these valves in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). C. Evaluation A deviation from the Appendix R, Paragraph III.L.3 requirements exists in the emergency feedwater pump building. This deviation is justified based on the analysis and our assertion that additional modifications would not enhance fire protection safety.

9) Remarks 3.5.3 Review and Analysis A review of each of the lines listed in subsection 3.5.1 is provided to identify lines which could open and cause a LOCA.

The flow through each high -low interface path will be evaluated. If the flow is less then the capacity of one charging pump, then the open path is not considered a LOCA and no further circuit analysis is required. The effect of the flow on system operation would still need to be evaluated. If the flow exceeds the capacity of one charging pump, then further circuit analysis is required per the criteria in Section 3.1.8 to demonstrate that spurious valve operation can not result in an open path. A specific flow value may not be documented for cases where it is obviously unacceptable (ex. RHR/RCS isolation valves). Alternatively, a circuit analysis per the criteria in Section 3.1.8 can be used to demonstrate that spurious valve operation cannot result in an open high -low interface path so no flow analysis is needed. 3.5.3.1 Chemical and Volume Control System

a. Excess letdown line The high-low pressure interface is downstream of control valve CS

-HCV-123. This is a normally closed, fail close diaphragm valve. Upstream of CS -HCV-123 are two normally closed, fail close diaphragm valves, CS -V175 and CS -V176. Spurious opening of one valve will not open the path and prevent safe shutdown. The operators will prevent further spurious openings by tripping the 125 Volt dc power supply breaker for valves CS -V175 and CS -V176 in the Train B switchgear room. An additional disabling capability exists at the disabling panel for CS -V-175 in the Train B diesel generator room (Fire Area: DG -F-2B-A) should the primary capability be inaccessible due to a fire in the switchgear room.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 9 Section 3.5 Page 3.5-3 b. Normal letdown line The high-low pressure interface is downstream of parallel valves CS -HCV-189 and CS-HCV-190 (letdown flow control valves). These valves are motor operated drag valves. Upstream of CS -HCV-189 and CS -HCV-190 are fail close diaphragm valves CS -V145, RC-LCV-459, and RC-LCV-460. CS-HCV-189 or 190 failing full open results in a maximum flow rate that exceeds the charging pump capability . To isolate this path, the operator will close CS -V-145, RC-LCV-459 or RC-LCV-460. RC-LCV-459 and RC -LCV-460 can also be closed by tripping a circuit breaker at the 125 Volt distribution panels in the A Train switchgear room (Fire Area: CB -F-1A-A). An additional disabling capability exists in the Train A diesel generator room (Fire Area: DG -F-2A-A) for RC-LCV-459. c. Reactor coolant pumps seal bleedoff lines The high-low pressure interface is downstream of valves CS -V44 (Loop 3), CS -V59 (Loop 4), CS -V10 (Loop 1), CS -V28 (Loop 2). These valves are fail open diaphragm valves. However, these valves are not used for pressure reduction. The RCP seals are the pressure reduction device. If the bleedoff line is isolated downstream of the high/low interface, the pressure would equalize across the seals and pressurize the bleed lines. The low pressure portion of the bleedoff line is protected with relief valves CS -V173, CS-V794, and CS -V250. Bleedoff from the RCP seals will equal a maximum of 12 GPM either discharging to the reactor drain tank (RDT) if containment isolation valves CS -V168 or CS-V167 (normally open motor operated valves) close or to the charging pump suction. RCS fluid to the RDT is not recoverable but will be made up by flow to the charging suction from BAT or RWST. 3.5.3.2 Residual Heat Removal System The high-low pressure interface is downstream of motor operated valves (MOV) RV -V23 (Loop 1) and RC-V88 (Loop 4). Upstream of each MOV is MOV RC -V22 and RC -V87. All four valves are normally closed when the RCS is above RHR design pressure of 600 psig and interlocked to prevent opening when RCS pressure is above 365 psig. During normal operation these normally closed MOV 's will also be deenergized at their respective motor control center, thus there is no possibility of a short circuit, or hot short circuit opening the valves. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 9 Section 3.5 Page 3.5-4 3.5.3.3 Pressurizer Power Operated Relief Valves The high-low pressure interface is downstream of paralleled valves RC -PCV-456A and RCV-PCV-456B. These valves are normally closed, fail closed solenoid operated valves. Upstream of each of these valves are the PORV block valves RC-V122 and RC -V124. These MOV's are normally open. Since the PORV block valves are normally open MOVs and will be closed for all fires which could cause spurious PORV operation, a hot short to the control logic or power to the PORV or block valves will not cause PORV blowdown. The operators will prevent the opening of the solenoid operated valves RC -PCV-456A and RC-PCV-456B by tripping their respective power supply breakers in the Train A and Train B switchgear rooms (Fire Areas: CB -F-1A-A and CB-F-1B-A). An additional disabling capability exists in the Train A and Train B diesel generator rooms (Fire Areas: DG -F-2A-A and DG-F-2B-A) respectively should the primary capability be inaccessible due to a fire in the switchgear room. 3.5.3.4 Reactor Vessel Head Vent The high-low pressure interface is downstream of valve, RC -V323. This is a normally closed MOV. Upstream of RC -V323 is a normally closed, solenoid valve, RC -FV-2881. Spurious opening of one valve will not open the path. The operators will prevent further spurious openings by disabling the normally closed MOV RC -V323 and solenoid RC -FV-2881 at the motor control center and 125 volt dc distribution panel, respectively, in the B Train switchgear room (Fire Area: CB-F-1B-A). An additional disabling capability exists for RC-FV-2881 in the Train B diesel generator room (Fire Area: DG -F-2B-A) should the primary capability be inaccessible due to a fire in the switchgear room.

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 9 Section 3.6 Page 3.6-1 3.6 ASSOCIATED CIRCUITS 3.6.1 Definition of Associated Circuits of Concern Circuits other than those directly required for the safe shutdown functions which have the potential to affect or prevent post -fire safe shutdown are considered associated circuits of concern. Associated circuits of concern are defined as those cables (Class 1E and non -Class 1E) that: a. Have a physical separation less than that required by Section III.G.2 of Appendix R, and b. Have one of the following:

1) a common power source with the safe shutdown equipment (redundant or alternative) and the power source is not electrically protected from the circuit of concern by coordinated breakers, fuses or similar devices, or

2) a connection to circuits of equipment whose spurious operation would adversely affect the safe shutdown capability (e.g., RHR/RCS isolation valves, PORVS, steam atmospheric dump valves, etc.), or

3) a common enclosure (e.g., panel) with the shutdown cables (redundant or alternative) and a) are not electrically protected by circuit breakers, fuses or similar devices, or b) will allow propagation of fire into the common enclosure.

3.6.2 Discussion of Methodology Sections 3.6.2.1, 3.6.2.2 and 3.6.2.3 in conjunction with Figure 3.6-1 describes the methodology utilized to address the following types of associated circuits:

a. Common power source

b. Spurious operation

c. Common enclosure

SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 9 Section 3.6 Page 3.6-2 3.6.2.1 Common Power Source As stated in FSAR Section 8.3.1.4, all non -Class 1E circuits are associated relative to electrical separation with either Train A or Train B in accordance with the provisions of FSAR Appendix 8A Section 4.5a. Based on these design consideration s, associated circuits can be powered from the Class 1E electrical distribution emergency (EDE) system or from the

non-Class 1E electrical distribution (ED) system and further may be routed in the same raceways and terminate in the same enclosure as Class 1E circuits. Although all safe shutdown circuits are powered from the EDE system, not all safe shutdown circuits are considered to be Class 1E. There are no Safe shutdown circuits, which require electrical power to operate, powered from the ED system. Associated circuits that are powered from the EDE system, and are associated with the safe shutdown circuits by a common power supply, are protected by a coordinated circuit breaker and; hence, are not considered to be associated circuits of concern. The above design considerations eliminates as associated circuits of concern all circuits which have no deleterious impact on safe shutdown. 3.6.2.2 Spurious Operation The review of each system required to satisfy the safe shutdown functions included all valves necessary to operate the system or maintain the system process boundaries. This assures that the safe shutdown system will operate as designed. If valves or other equipment from one train (i.e., Train A) are required for operation or could prevent operation of the other train (i.e., Train B), then additional reviews are performed to determine the failure modes and provide manual actions or operations of other equipment that would prevent the spurious operation from affecting safe shutdown. An example of this is the primary component cooling water containment isolation function which requires that both Train A and Train B valves remain open. The inboard containment isolation valve is the same train as the pumps which supply primary component cooling water while the outboard valve is of the opposite train but could be operated manually upon loss of power or damage to electrical circuit. To prevent the spurious operation of various safety injection system valves, containment isolation valves and service water valves, the engineered safety features actuation system logic and the tower actuation logic are disabled by tripping their power supplies after a control room evacuation. In several instances (e.g., RHR/RCS isolation valves), the power supplies are permanently disabled (breaker tripped and locked out) to prevent spurious operation. The spurious operation of valves protecting high -low pressure interfaces is discussed in Section 3.5. See Section 3.1.8 for criteria to evaluate components for spurious operation . SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50, Appendix R Safe Shutdown Capability Rev. 9 Section 3.6 Page 3.6-3 3.6.2.3 Common Enclosures The deleterious effects of fire on associated circuits in common enclosures is eliminated by the following three design considerations:

a. Coordinated circuit breakers, fuses or similar devices will assure that the associated circuit failure does not prevent the redundant train from performing its safe shutdown function. b. The cables are qualified to IEEE Standard 383; hence, the propagation of the fire from one train to the redundant train in another fire area/zone is very unlikely.

c. Train and channel separation for cable routing is assured by a computerized cable routing program which does not allow cables with different circuit code assignments to be routed in the same raceways.

Based on the above design considerations, associated circuits in common enclosures are not considered associated circuits of concern.

These drawings were typical of the P & I Diagrams which were marked for each safe shutdown function and not all inclusive, thus they have been removed from this appendicies. The typical diagrams included in this section were only to show the methodology used for the original report preparation and were not in tended to be updated for report revisions. The latest design documents, not these typical drawings, should be used to evaluate the Safe Shutdown Capability. SEABROOK STATION Fire Protection of Safe Shutdown Capability 10CFR50. Appendix R Schematic Diagrams & Cable Schematics (Typical) Rev 5 Appendix II Page II-1 Schematic Diagrams & Cable Schematics (Typical) This section originally contained drawings that were typical of those which were marked for each safe shutdown function. The typical drawings in cluded in this section were only to show the methodology used for the original report preparation. These typical drawings were not intended to be updated for report revision. The original drawings were provided to show marked-up electrical schematic diagrams, cable schematics, and cable tables for the Train A decay heat removal safe shutdown function. The drawings were marked by shading and by cross-hatching. The equipment and cables which were shaded were isolated by a "Local Remote" selector switch or other isolation device and were not considered for further review. The equipment and cables which have been cross-hatched were analyzed, and it was determined that there was no effect on safe shutdown capability. These equipment and cables were not considered for further review. The latest design documents, not these typical drawings, should be used to evaluate the Safe Shutdown Capability.

Equipment is mechanical with no electrical requirement.

2. CS-V-423, 410, 416, 431, 437, 439, 442 are non

-electrically operated valves and will be manually positioned as required to provide their reactivity control function during safe shutdown.

3. Electrical conduit plan drawing, 310766, listed only to show fire zone correlation reference to Primary Auxiliary Building area covered by piping Drawings 805216, 805229, 805230, where Valves CS-V-410, 416, 423, 431, 437, 439, 442 are identified in plan and section.

4. This equipment is listed because it can spuriously start due to cable failure in the boration & dilution flow control valve control circuits. Spurious pump start by itself from failure of its cables is not of concern since CS-FCV-111A remains closed.

.Notes  1. The equipment is mechanical with no electrical requirement. 

2. During normal operation, this equipment is in its safe shutdown position (locked closed). To prevent spurious operation, its circuit breaker is administratively controlled locked open (off).

3. Disabling the valve at the appropriate control location will reposition it for safe shutdown.

4. Air is not needed to position or to reposition the valve for safe shutdown.

5. The review of this valve was conducted with the assumption that it will be closed from the Control Room prior to evacuation and that a fire will not reset its logic before the operator could man the remote shutdown station and throw the "Remote-Local" switches to "Local". Its cables and supporting controls were listed to analyze the possibility of the valve reopening after the isolation switch has been positioned to "Local". 6. Circuit breaker tripped to disable the redundant controls.

.Notes  1. Equipment is mechanical with no electrical requirement.

2. CS-V-423, 410, 416, 431, 437, 439, 442 are non

-electrically operated valves and will be manually positioned as required to provide their reactivity control function during safe shutdown.

3. Electrical conduit plan drawing, 310766, listed only to show fire zone correlation reference to Primary Auxiliary Building area covered by piping Drawings 805216, 805229, 805230, where Valves CS

-V-410, 416, 423, 431, 437, 439, 442 are identified in plan and section.

4. This equipment is listed because it can spuriously start due to cable failure in the boration and dilution flow control valve control circuits. Spurious pump start by itself from failure of its cable is not of concern since CS

-FCV-111A remains closed so the pump cables are not listed.

5. Disabling the valves at the appropriate control location will reposition CS

-FCV-110B and C S-FCV-111B for safe shutdown. Air is not needed to position or to reposition the valve for safe shutdown.

.Notes  1. Equipment is mechanical with no electrical requirements. 

2. Electrical conduit Plan Drawing 310443, listed only to show fire zone correlation reference to control building area covered by HVAC Drawing 604094 where CBA Dampers 24 D, E, and F are identified in plan.

3. Process connections showing positioning of air operated dampers, DP-24A-F, by pneumatic temperature indicating controllers, CBA-TIC-5571 and 5572, are detailed on I&C Loop Diagrams 510159 and 510160.

4. Instrument air is required for normal positioning of dampers for area temperature control. Should IA fail, dampers 24A, 24B, 24E and 24F will fail "as is" and 24C and 24D fail open. The operators can start and stop fans to maintain switchgear room habitability.

5. Dampers fail open on loss of instrument air, which is the safe shutdown position.

Rev. 5 Appendix IV Page IV-1 Raceway Arrangement Drawings (Typical) This section originally contained photographs of marked raceway arrangement drawings for several fire areas/zones of the plant containing redundant Safe Shutdown equipment and cables. The typical drawings included in this section were provided to only show the methodology used for the original report preparation. These typica l drawings were not intended to be updated for report revisions. These original drawings were typical of the raceway arrangement drawings which were marked for each fire area/zone containing safe shutdown equipment and cables. The latest design documents, not these typical dr awings, should be used to evaluate the Safe Shutdown Capability.}}
