Response to Request For Additional Information (RAI) AST 5

Background

On August 1, 2001 (Serial: BSEP 01-0063), Carolina Power & Light (CP&L) Company submitted a license amendment application to allow a full-scope implementation of an Alternative Radiological Source Term (AST) for the Brunswick Steam Electric Plant (BSEP),

Units 1 and 2. Subsequently, on December 20, 2001, the NRC Equipment and Human Performance Branch (IEHB), provided an electronic version of a RAI regarding the use of manual, instead of automatic, initiation of control room isolation following a fuel handling accident.

NRC Question 5-1 Provide a description of all operator actions or manipulations required to complete the manual control room isolation. For each action or manipulation:

A.

State the location and describe any adverse environmental conditions (e.g.,

temperature, humidity, noise, lighting, radiation).

B.

Describe the ingress and egress paths and accessibility to the required equipment.

C.

Provide a copy of the applicable procedural guidance.

D.

Describe the required training, including operator qualifications and provide a copy of the related training material.

E.

State the information required and instrumentation relied upon to determine the need for action and to verify action completion, including instrument quality requirements.

F.

State the amount of time assumed to recognize the need for action and the amount of time assumed available to complete the action after the need is recognized.

BSEP 02-0012 Page 2 of 7 Provide estimates of the time actually required to complete these actions and the basis for these estimates.

G.

Describe the operator's ability to recover from credible errors in performing the action or manipulation.

H.

Describe the level of staffing required to complete the action, concurrent duties or responsibilities of the required personnel, and basis for concluding adequate availability of required staff.

I.

State the risk significance of the action.

CP&L Response Manual Control Room isolation is accomplished by manipulation of two control switches located in the Control Room. The two control switch actions required to accomplish Control Room isolation are: place one Control Building emergency recirculation fan in "ON"; and stop the Control Building washroom exhaust fan. The verifications and control switch actions are included on the same Control Room panel. The picture below, taken at the BSEP simulator, shows a former control room shift superintendent pointing to the two required control switches.

Part A:

The actions required to isolate the Control Room Heating, Ventilation, and Air Conditioning System (i.e., change from normal to emergency recirculation mode)

BSEP 02-0012 Page 3 of 7 are accomplished by manipulation of control switches in the Control Room. No adverse environmental conditions are anticipated.

Part B:

Since the realignment of the Control Room to emergency recirculation mode is accomplished entirely in the Control Room, there are no ingress or egress paths or accessibility requirements applicable to the evolution.

Part C:

The procedural guidance for manual start-up of the Control Building Ventilation System in emergency recirculation mode, which includes Control Room emergency recirculation, is contained on pages 14 and 15 of plant procedure OOP-37, "Control Building Ventilation System Operating Procedure." Procedure steps 5.3.2.1.a and 5.3.2.1.d correspond with the two control switch manipulations described above which are necessary to accomplish isolation of the Control Room; procedure steps 5.3.2.1.e through 5.3.2.1.g are not required in order to ensure isolation of the Control Room is accomplished. A copy of plant procedure OOP-37 is provided in Enclosure 2.

Part D:

There is no special training or qualification for placing the Control Room Ventilation System in the emergency recirculation mode because the evolution is covered in existing normal system training for operators. However, placement of the Control Building Ventilation System in emergency recirculation mode is being covered as part of licensed operator continuing training on Emergency Operating Procedure changes associated with implementation of Extended Power Uprate. provides a copy of Lesson Plan LOCT-CLS-LP-500-02-1, Revision 0, for the licensed operator continuing training. Placement of the Control Building Ventilation System in emergency recirculation mode is being addressed in conjunction with EOPs 1EOP-01-RVCP (i.e., page 11 of the lesson plan) and OEOP-04-RRCP (i.e., page 12 of the lesson plan).

Part E:

The following information and indications are used to determine the need to manually initiate Control Room isolation:

(1)

Fuel Handling Accident: Continuous communications are maintained between the refuel bridge and the Control Room during refueling, thereby providing immediate notification of the occurrence of a dropped fuel assembly. Back-up communications, via Plant Public Address System, can also be used for this purpose. A radioactive release associated with a dropped fuel bundle would be indicated by a refuel floor high radiation alarm, a Reactor Building ventilation high radiation alarm, and by various area radiation monitor and continuous air monitor alarms. In support of AST implementation, BSEP Abnormal Operating Procedure (AOP)

OAOP-5.0, "Radioactive Spills, High Radiation, and Airborne Activity," is being revised to direct operator realignment of the Control Room

BSEP 02-0012 Page 4 of 7 Ventilation System to the emergency recirculation mode following a dropped fuel assembly.

(2)

Loss-of-Coolant Accident (LOCA), Main Steam Line Break (MSLB), and Control Rod Drop Accident (CRDA): Symptom-based Emergency Operating Procedures (EOPs) will provide guidance to manually initiate Control Building ventilation emergency recirculation mode upon detection of selected indications. Indications used as input for these EOPs include:

high main steam line radiation, high off-gas radiation (i.e., steam jet air ejector or plant stack), high Reactor Building roof ventilation radiation, and high Turbine Building ventilation radiation.

As previously stated, manual Control Room isolation is accomplished by manipulation of two control switches located the on the benchboard section of the Reactor Turbine Gage Board (RTGB) in the Control Room. Lights indicating the status of the associated fans and dampers are located immediately adjacent to each switch.

Part F:

Since the action to manually isolate the Control Room is based on indications, not requiring diagnosis of conditions, other than recognize/respond to the indication, the time required to decide that action is required will be extremely short. Total time to recognize the indication and to accomplish Control Room isolation is estimated to be substantially less than two minutes, based on operator experience.

In comparison, the AST analyses have been performed assuming manual isolation of the Control Room at 20 minutes following initiation of the accident.

Part G:

Placing the Control Room Ventilation System in the emergency recirculation mode (i.e., isolated) consists of two specific switch manipulations by the Control Operator to complete the alignment. The switches are located on the benchboard section of the RTGB, within eight inches of each other. In the event that incorrect switch manipulations were performed, the indicating lights associated with the correct switches would not change state to indicate proper alignment. Also, during off-normal events, standard practice is that required actions are verified, by another operator and/or the Shift Technical Advisor, to ensure proper alignment of equipment for the conditions that exist. If the operator should fail to actuate either of the two "required" switches, no action (i.e., resets, manual re-alignment, etc.) would be necessary to correctly align the Control Room Ventilation System other than to actuate the necessary switch.

Part H:

Placing the Control Room in the emergency recirculation mode is accomplished in accordance with the system operating procedure (i.e., OOP-37). Only one Control Operator is needed complete alignment of the Control Room Ventilation System to the emergency recirculation mode. Realignment of the Control Room Ventilation System to the emergency recirculation mode is an existing, normal

BSEP 02-0012 Page 5 of 7 response to symptom-based conditions. During off-normal events, standard practice is that required actions are verified, by another operator and/or the Shift Technical Advisor. The actions necessary to align the Control Room Ventilation System to the emergency recirculation mode are currently being accomplished with the normal Control Room staffing; no change to this capability will occur as a result of the proposed crediting of manual isolation of the Control Room. On this basis, CP&L has concluded that adequate availability of required staff exists.

Part I:

There is no risk associated with placing the Control Room in the emergency recirculation mode.

NRC Question 5-2 Provide a system description manual or training lesson plan for "Control Room Ventilation."

CP&L Response A copy of the system description for Control Building Ventilation System (i.e., SD-37, "Control Building Heating, Ventilation, and Air-Conditioning System") is provided in Enclosure 4.

NRC Question 5-3 Provide a simplified schematic drawing of "Control Room Ventilation," including key valves and dampers.

CP&L Response The normal line-up for the Control Building Ventilation System is shown in Figure 37-1, "Control Building Ventilation System: Normal Flowpaths" of the system description, SD-37, provided as Enclosure 4. The emergency recirculation mode line-up (i.e., Control Room isolated) for the Control Building Ventilation System is shown in Figure 37-2, "Control Building Ventilation System: Detected High Rad/Fire" of the system description.

NRC Question 5-4 Provide a description of the effect, if any, of the following relaxations on operator ability to identify the need for, and complete, manual control room isolation:

A.

Control Room Emergency Ventilation intake radiation monitors not required to be operable B.

Secondary containment instruments allowed to be inoperable

BSEP 02-0012 Page 6 of 7 CP&L Response In regards to the relaxations requested for Control Room ventilation intake radiation monitors and the secondary containment instruments (i.e., Reactor Building ventilation radiation monitor),

during Modes 4 and 5, these instruments will not be relied on to identify the need for Control Room isolation.

As discussed in the response to NRC Question 5-1, Part E, the indication relied upon during refueling is the report of a dropped assembly by direct communications with the refuel bridge (i.e., a fuel handling accident). For the LOCA, MSLB, and CRDA, there are no relaxations in the requirements for instrument availability.

NRC Ouestion 5-5 Provide a description of any operational or safety benefits anticipated from the substitution of manual for automatic initiation of control room isolation.

CP&L Response The removal of Technical Specification requirements for automatic initiation of Control Room isolation is only being requested for periods when both units are in Modes 4 and 5. During periods when either unit is operating in Modes 1, 2, or 3, the capability for automatic initiation of Control Room isolation will continue to be required by the Technical Specifications. As such, the use of the manual initiation of Control Room isolation is a conservative assumption used in the Control Room operator dose calculations for the LOCA, MSLB, and CRDA.

The substitution of manual for automatic initiation of Control Room isolation is a change associated with implementation of the generic Boiling Water Reactor (BWR) Technical Specification change, Technical Specification Task Force (TSTF) Standard Technical Specification Change Traveler TSTF-5 1, "Revise Containment Requirements During Handling Irradiated Fuel and Core Alterations," Revision 2. The TSTF-51 generic change has been previously approved by the NRC. TSTF-51 includes Technical Specification changes eliminating requirements for the operability of the Control Room Ventilation System (i.e.,

referred to as the Main Control Room Environmental Control (MCREC) System in the TSTF-51 Technical Specification mark-ups), and its associated actuation instrumentation, during core alterations. This change is based on the recognition that, after reactor shutdown, decay of short lived fission products greatly reduces the fission product inventory present in irradiated fuel.

Although the generic TSTF-51 change supports elimination of Technical Specification operability requirements for the Control Room Ventilation System isolation initiation instrumentation during core alteration activities, because the BSEP Control Room is a common facility for both BSEP units, substantial operational benefit (i.e., in regards to the system for

BSEP 02-0012 Page 7 of 7 automatic isolation of the Control Room) will only be recognized during periods involving a dual-unit shutdown in conjunction with core alterations on one or both units.

SUMMARY

The procedures listed below include changes required for EPUR, the core reload, and outage related ESRs. Administrative type changes, and small wording changes, are not detailed below.

PROCEDURE CHANGES 001-37 This revision incorporated the new Unit 1 APRM downscale value of 2%, the Unit 1 BPV full open press of 950 psig, the Unit 1 MAFP values, the Unit 1 MCFI values, and the new Unit 1 LL4 value and graph. The new Unit 1 HCTL, PSP, and MCUTL graphs were also added. Step RR-2 of the EPG was revised to replace "approaching" with "before'. Finally, the discussion for the 150 degree F temperature for the Suppression Pool was revised to account for the new temperature values calculated for Extended Power Uprate in calculation El 1-0028.

001-37.1 Changes resulting from LEP-01, LEP-02, SEP-01, SEP-05, and AEDP changes, and the new EOP-01 -SEP-1 1.

001-37.3 Changes resulting from EOP-01 -RSP changes.

001-37.4 Changes resulting from EOP-01-RVCP changes. In addition, the discussion for Step RC/L-09 was revised to address that containment pressurization is credited with maintaining NPSH margins for Unit 1.

001-37.5 Changes resulting from EOP-01-LPC changes. In addition, the discussion for Steps RC/L-19 through 27, DW/T-09 through 17, and PC/P-04 through 13, were revised to address that containment pressurization is credited with maintaining NPSH margins for Unit 1.

001-37.6 Changes resulting from OEOP-01-RXFP changes.

001-37.8 Changes resulting from OEOP-02-PCCP changes. In addition, the discussion for Steps SPIT-01 through 04 was revised to address that containment pressurization is credited with maintaining NPSH margins for Unit 1.

001-37.10 Changes resulting from OEOP-04-RRCP changes.

OEOP-01-NL This revision incorporates the new Unit 1 BPV full open press of 950 psig, changed the wording associated with the discussions on TAF, LL4 (including a new Unit 1 graph), and LL5 to include GE14 for U1, and included the new Unit 1 MCFI values. The new Unit 1 MCUTL graph and MAFP values were also added. The new Unit 1 MDRIR Page 8 of 17 LOCT-CLS-LP-500-02-1 Rev. 0

OEOP-01 -UG OEOP-01-LEP-01 STUDENT HANDOUT graph, APRM downscale value of 2%, PSP graph, and HCTL graphs were incorporated. Finally, the discussion for the 150 degree F temperature for the Suppression Pool was revised to account for the new temperature values calculated for Extended Power Uprate in calculation El 1-0028.

This revision incorporates the new Unit 1 HCTL and PSP graphs, the new Unit 1 APRM downscale value of 2%, and the new EOP-01-SEP 11 required by implementation of Alternative Source Term. Note 5 was added to the Group 2 valves to denote the removal of various valves from the Group 2 isolation requirements, though they still receive a Group 2 signal. The new Unit 1 MCUTL and LL-4 graphs were also incorporated. The new Unit 1 LL-4 value of -32.5 inches was also incorporated. Attachment 7 was revised to include the new Unit 1 Unit Trip Load Shed Selector switch key. Finally, the discussions for RVCP, PCCP, and RRCP were revised to account for the new wording of the exit step for each procedure (i.e. is the procedure required to control the associated parameters).

This revision adds the Unit Trip Load Shed Selector switches for the Heater Drain Pumps to Section 2. The switch for the pump to be started must be placed in the "DISABLED" position before the pump is started, and returned to the "ENABLED" position after the pump is stopped.

OEOP-01-LEP-01 Revision 19 Section 7 of the procedure is being deleted due to having inadequate technical guidance to allow successful completion of the activity. The use of the Condensate Transfer System (CTS) as a source of water for injection into the reactor pressure vessel has been included as a potential source of water when all other systems have failed to provide a method of injection. The section aligned the CTS header to a selected Condensate Filter Demineralizer (CFD) by opening the N (System Backwash Water Supply), Ns (Slow Backwash Water Supply Valve) and W (CFD Backwash Inlet/Precoat Outlet) valves. The water was then routed through the E (CFD Outlet Valve) to the condensate header. A pathway was aligned through a condensate booster pump, through the feedwater heater bypass valves, and reactor feedpump bypass valve through the feedwater discharge valves to the reactor pressure vessel. This flow path should have provided an injection source at a pressure of approximately 100 psig to the reactor pressure vessel. The problems associated with the flow path were:

The E (CFD Outlet) valve could not be opened as long as the A (CFD Inlet) valve was closed.

LOCT-CLS-LP-500-02-1 Rev. 0 Page 9 of 17

OEOP-01-LEP-02 OEOP-01-SEP-01 OEOP-01-SEP-05 OEOP-01 -SEP-i 1 STUDENT HANDOUT

"* The W (CFD Backwash Inlet/Precoat Outlet) valve would not remain open when the E (CFD Outlet) valve was opened.

The Hotwell Level Control Spill to Condensate Storage Tank Valve, CO-LV-1-1 is used in a manual mode to control hotwell levels during normal operation. The valve may not have been closed during a transient, which required the use of this procedure. This procedure did not have a step to ensure that the valve was closed.

This could have diverted the water back to the CST instead of to the reactor pressure vessel.

In attempting to determine how the procedure should be revised, it was recognized that additional evaluation of the use of the CTS header through the CFD was needed. Therefore the current guidance in the procedure for using the CTS header is being deleted.

Additional minor changes to the procedure are being implemented at this time. They are replacement of WR/JO with WO, addition of an independent verification step for the E 11-F017A(B) in section 3 step 11, deletion of approval signatures from cover page, deletion of list of effective pages, relocation of reason for revision page, and correction of page references within the procedure.

This problem with the procedure has been documented in AR 52562 and is not associated with EPUR.

This revision changes the initial operator actions to make separate Unit 1 and Unit 2 steps for the IRM and APRM recorders. Unit 1 will no longer have the switch to swap the recorders from APRMs to IRMs.

Unit 1 will monitor power on the APRMs until the IRM recorders are on scale. The IRMs must be inserted to get the recorders on scale.

This revision incorporates the Alternative Source Term requirement to maintain the Unit 1 SGT-V8 and SGT-V9 valves as normally open valves. Separate Unit 1 and Unit 2 steps were created where necessary. The CAC-CS-4337 and 4338 override switches were deleted from Section 2 since the valves they override are not operated in this section.

This revision incorporates the Alternative Source Term requirement to maintain the Unit 1 CAC-V152 and CAC-V153 valves as normally open valves. Separate Unit 1 and Unit 2 steps were created where necessary. A Unit 1 step was also added to ensure the reactor Building Ventilation System was in service prior to opening the Unit 1 CAC-V152 and CAC-V153 valves upon completion of the procedure.

This is a new procedure to implement the Alternative Source Term requirement to establish a primary or alternative main steam line LOCT-CLS-LP-500-02-1 Rev. 0 Page 10 of 17

OEOP-01-AEDP 1 EOP-01-RSP 2EOP-01-RSP 1 EOP-01 -RVCP 2EOP-01-RVCP STUDENT HANDOUT leakage control pathway to the main condenser. The alternative pathway requires manual valve operation is power is not available to the required valves.

This revision added notes as required to inform the operator that the following actions would affect any established OEOP-01 -SEP-i 1 leakage control pathways. A step was also added to state that if the actions of Step C.6 cannot depressurize the reactor vessel, the operator is to continue in the procedure. A step was also added to reposition those valves utilized by OEOP-01 -SEP-1 1 to the positions required by that procedure upon completion of this procedure.

This revision incorporated the new APRM downscale value of 2%, the new BPV full open press of 950 psig, a new step to go to LPC if control rod position cannot be determined, and the new IRM and APRM recorders where switching between recorders is no longer necessary.

This revision incorporated the new Unit 1 APRM downscale value of 2% since this will be the value used in the simulator. This change will not be incorporated in the actual Unit 2 procedure revision. A new step to go to LPC if control rod position cannot be determined was also added. This revision also accounted for the new Unit 1 IRM and APRM recorders where switching between recorders is no longer necessary since this will be the condition in the simulator. This change will not be incorporated in the actual Unit 2 procedure revision.

This revision incorporated the new Unit 1 APRM downscale value of 2%, added a new entry condition like that on LPC of a reactor scram required by PCCP, SCCP, or RRCP, and reworded exit step RVCP-6 to ask if the procedure is required for control of reactor vessel parameters (instead of does an entry condition exists). This revision also added the Alternative Source Term requirements to initiate SLC, place the Control Building Emergency Recirculation system in service (a new hard card is being developed), and to perform OEOP-01-SEP 11, all before existing to the SAMG procedures. The new BPV full open press of 950 psig, and a revision to Step RC/P-1 1 to ask if ED "is or was" required, were also incorporated.

This revision incorporated the new Unit 1 APRM downscale value of 2% since this will be the value used in the simulator. This change will not be incorporated in the actual Unit 2 procedure revision. A new entry condition like that on LPC of a reactor scram required by PCCP, SCCP, or RRCP, was added, with exit step RVCP-6 being reworded to ask if the procedure is required for control of reactor vessel parameters (instead of does an entry condition exists). Step RC/P-1 2 was revised to ask if ED "is or was" required.

This revision incorporated the new Unit 1 APRM downscale value of 2% since this will be the value used in the simulator. There will be no actual Unit 2 procedure revision.

This revision incorporated the new Unit 1 MAFP table values that now agree with the Unit 2 values, the new Unit 1 MCFI table values, and the new Unit 1 MCUTL graph.

This revision changed the wording in exit Step PCCP-5 to ask if the procedure was required to control primary containment parameters instead of if an entry condition exists. Existing step number discrepancies were also corrected.

This revision changed exist Step RR-6 to ask if the procedure was required for control of radioactivity releases instead of if an entry condition exists. Step RR-12 and numerous steps in the lower portion of the flowchart, were reworded to replace "periodically" with "as required due to changing plant conditions". A new step (RR-27) required by the Alternative Source Term analyses was added to ensure the Control Building Emergency Recirculation System was placed in service if fuel failure is indicated. Steps RR-14 and 15, and RRITB-03 were reworded to ensure that the entire Turbine Building Ventilation System is restarted, and not just the filtration system.

Steps RR-24 through 26 were reworded to replace "approaching" with a "before" step. Table 1 was revised to delete the reference to the section of E&RC-2020 used to perform the needed calculation, and to replace "Tech Spec" with "ODCM".

This revision added words to page 17 to note that containment pressurization is credited in Unit 1 with maintaining NPSH margins.

The new Unit 1 MDRIR and PSP graphs were also incorporated.

This revision added the new Unit 1 MDRIR and PSP graphs.

This revision added words in numerous places to note that containment pressurization is credited in Unit 1 with maintaining NPSH margins. Pages 218 through 221, and 223 were revised to include all of SAMG-01 Step PCF-RP-1 in each graphic, and delete reference to Step PCF-RP-3 since it does not exist. In addition, page 221 was revised to add a discussion of the Alternative Source Term requirement to inject SLC. Pages 227 through 234 were revised to include all of SAMG-01 Step PCF-RVP-1 in each graphic, and to delete reference to Step PCF-RVP-3 since it does not exist.

LOCT-CLS-LP-500-02-1 Rev. 0 Page 12 of 17 STUDENT HANDOUT OSAMG-07 OSAMG-10 OSAMG-12 This revision incorporates changes necessary to account for the possible implementation of EOP-01 -SEP-1 1, and its associated valve positions. A note was also added to ensure that re-entry into the Turbine Building is coordinated with the TSC and OSC. New steps were also added to ensure that those valves required to be in certain positions by EOP-01-SEP-1 1 are returned to those positions.

This revision incorporates the Alternative Source Term requirement to maintain the Unit 1 CAC-V152 and CAC-V153 valves as normally open valves. Separate Unit 1 and Unit 2 steps were created where necessary. A Unit 1 step was also added to ensure the reactor Building Ventilation System was in service prior to opening the Unit 1 CAC-V152 and CAC-V153 valves upon completion of the procedure.

This revision incorporates the Alternative Source Term requirement to maintain the Unit 1 SGT-V8 and SGT-V9 valves as normally open valves. Separate Unit 1 and Unit 2 steps were created where necessary. The CAC-CS-4337 and 4338 override switches were deleted from Steps 4.4 and 4.6 since the valves they override are not operated in these steps.

Along with the above procedure revisions, revisions to the Caution 1, Ctmt Limits, and level graphs aids were made. SPDS changes will also occur. BESS has been informed of the need to revise the TSG aids that they control.

1.0 PURPOSE 1.1 System Purpose The Control Building Heating, Ventilation and Air Conditioning (HVAC) System performs the following functions:

1.1.1 Maintains all occupied areas within the temperature ranges desired for human occupancy.

1.1.2 Maintains the various Control Building areas at the temperature conditions which provide for optimum operation of equipment.

1.1.3 Provides for isolation, the emergency filtration of Control Room air, and positive pressurization upon the detection of excessive radiation levels or smoke such that habitability conditions are maintained.

1.1.4 Provides for the automatic isolation of the Control Room atmosphere upon the detection of chlorine gas such that habitability conditions are maintained.

1.2 Design Basis The Control Building Heating, Ventilation, and Air Conditioning System is designed to permit continuous occupancy of the Control Room (Habitability Envelope) under normal operating conditions and under the postulated design basis accidents including a complete rupture of the chlorine tank car throughout the life of the plant. This system is also designed to maintain optimum atmospheric conditions within the various Control Building areas for the safety of plant personnel and equipment, and to prevent the accumulation of an explosive mixture of hydrogen gas released from the plant batteries.

The HVAC equipment, controls, and ductwork supports are designed to seismic Class I and are protected by tornado-proof construction. Portions of the system are also safety related. Redundant ventilating, air conditioning, and emergency filtering equipment are provided to ensure proper environmental conditions within the Control Room, computer rooms, and the electronic workrooms.

I SD-37 I

Rev. 2 Page 6 of 57

The Control Room air conditioning subcooling system is nonsafety related. Failure of this subsystem does not affect the operability of the Control Room air conditioning condensing unit. The heat exchangers and liquid lines for the condensing units are seismically qualified/supported to prevent a seismic event from affecting the condensing unit.

1.3 General System Description The Control Building Heating, Ventilation, and Air Conditioning System consists of individual once-through ventilation subsystems, a recirculating ventilation subsystem, and an emergency air filtering subsystem (Figure 37-1).

Redundant ventilating, air conditioning and emergency filtering equipment is provided to ensure proper environmental conditions within the Control Room, Computer Rooms, Electronic Equipment Rooms, and Electronic Workrooms.

The various system supply fans draw outside air into the Control Building through two tornado pressure check valves. The air is then filtered by the supply plenum air filter and distributed to the various ventilation subsystems.

Each Cable Spreading Room, each Battery Room, and the Mechanical Equipment Room is provided with a once-through ventilation subsystem equipped with an individual supply fan and exhaust fan. The supply fan for each subsystem takes suction from the supply plenum through a supply damper, and discharges to its associated room. The exhaust fan takes suction from the ventilated room and discharges through an exhaust damper and a tornado pressure check valve to the atmosphere outside the Control Building.

Heating for the mechanical equipment room is provided by two space heaters, one per unit. The cable spread rooms' temperature is regulated by thermostats that sense ambient air and start or stop the supply and exhaust fans to maintain the desired temperature. Temperature regulation for each of the Battery Rooms is accomplished by a temperature controlled supply duct heater and by temperature controlled vortex dampers located in the supply and exhaust ducting. The vortex dampers in the exhaust receive the same signal as the supply fan vortex dampers. Minimum air flow required to maintain less than 2% hydrogen during an equalizing battery charge is 900 scfm. Minimum air flow for proper duct heater operation is 1028 scfm. Maximum air flow during winter (1 5oF outside temp) for the duct heater to maintain 770F in the Battery Rooms is 1580 scfm. Minimum air flow during summer months (93oF outside temp) to maintain less than 125oF in the Battery Rooms is 3100 scfm.

I SD-37 Rev. 2 Page 7 of 57 1

The battery rooms are normally maintained at a negative pressure relative to the Cable Spread room to prevent the exfiltration of hydrogen generated during battery equalization. The room pressure changes with net air flow, based on the positions of supply and exhaust fan vortex dampers, which are positioned by each room's thermostat. The vortex dampers are adjusted to ensure more than the minimum flow (for both hydrogen dilution and supply duct heater operation) is obtained at all times, without allowing too much flow in the winter to negate the operation of the supply duct heater. Since the exhaust fans are physically larger than the supply, the rooms are normally at a negative pressure, even though there is no requirement for room pressure (i.e., the dilution flow maintains hydrogen at concentrations below its flammable limit).

The Control Room (Recirculating) Ventilation Subsystem provides conditioned air to the Main Control Room and its associated areas (i.e., Computer Room, bathrooms, kitchen, Security CAS, and the Electronic Equipment Room).

The Control Room Ventilation Subsystem make-up air and recirculated air are constantly filtered by the recirculation air filter to remove dust, smoke and other particles that may be present in the air. The nominal volume of normal make-up air (2000 cfm) sufficiently compensates for the normal exhaust (nominal 350 cfm) of the Control Room (bathroom) exhaust fan and the Control Room ex-filtration.

From the recirculation air filter, the air is routed to the air conditioning cooling coils. The Recirculating Ventilation System is equipped with three air conditioning units (one serving as a spare) capable of handling the large concentrated heat gains from the computers and electronic equipment, as well as the variable heat gains from personnel and lighting. Individual heating coils are located in the discharge ducting of each air conditioning unit cooling coil to aid in temperature control. An air cowl was installed at the inlet to the Control Building Ventilation System. The purpose of this cowling is to minimize the potential for smoke to enter the ventilation system should a fire occur in the ventilation area or control room area. Two 8'-0" x 8'-0" openings were cut in the roof above the ventilation system condensing units. The purpose of these holes is to ensure that the new Trane condensing units receive adequate air flow for the removal of heat from the refrigerant loop. These new openings are in close proximity to the existing air inlet for the Control Building Ventilation System such that there is a potential for the condensing unit exhaust air to be drawn into the ventilation system. If a fire were to develop in the condenser area the smoke from that fire could potentially be drawn back to the control room. Likewise, if the ventilation system were placed in the smoke removal mode, the exhausted smoke could also be drawn back into the ventilation system.

I SD-37 Rev. 2 Page 8 of 57

After conditioning, the air is directed to the suction of the three recirculating ventilation supply fans (one serves as a spare). The air discharged by the fans is routed to the Main Control Room area where it is dispersed to the various rooms. The air is then recirculated and conditioned for reuse.

0PT-23.1, Control Room Emergency Filtration System Operability Test is performed to check operability of the CBEAF System. The PT requires a minimum 15 minute run time. This ensures Tech. Spec. Surveillance Requirements are met and is also used for verification of the Run Timer accuracy (+/-10%).

The Run Timer is used to ensure charcoal sample results are taken at required Tech. Spec. Surveillance requirements (720 hrs).

2.0 COMPONENT DESCRIPTION/DESIGN DATA Table 37-2 is a list of the system fans and major components identifying their component number and location.

2.1 Tornado Pressure Check Valves (Dampers)

One function of the ventilation tornado pressure check valves is to protect the Control Building Heating, Ventilation, and Air Conditioning System from collapse in the event of a tornado. This is accomplished by automatic valve closure when negative pressure outside the building causes a surge evacuation of air from the building. During normal operation, the second function of the valves is to remain open to allow the passage of air. The two inlet check valves are equipped with springs which help close the valves when there is no air flow through the system. During normal operation, the ventilation fans provide sufficient air flow through the system to overcome the spring tension and open the valves to achieve the required air flow with a minimum of pressure loss through the valve. If the fans are shut down, the springs return the valves towards the closed position. In the event of a tornado during system operation, the negative pressure outside the building will reverse system air flow, opposing the ventilation fans. As this occurs, the valves are closed, preventing damage to the duct. As the tornado passes beyond the building area, the normal fan pressure reopens the valves, restoring the system to normal.

SD-37 Rev. 2 Page9of 57

In order for the discharge check valves to accomplish their intended purpose, they must close to prevent excessive outflow under tornado conditions, but must remain open during normal operations when system air outflow is acting against the closing side of the valve. If the movement of the valve plates were not restricted, normal air discharge would cause the valve to close, thereby shutting down the system. To prevent this, the valve plates are restrained from closing by linking them to a counterweight suspended inside the valve body. During normal operation, the counterweight will hold the valve plate open, allowing normal passage of ventilation air. During a surge discharge of air, such as would occur during a tornado, the increase in flow will create drag forces on the valve plate in excess of the counterweight.

This results in the closing of the valve and protects the ductwork from collapse. The discharge check valves are also equipped with equipment for remote testing. A double acting 80 psi air cylinder is attached to each counterweight to allow the weight to be lifted from the valve plate, and then restored to its normal/open position. Operation of the cylinder permits the cycling of the check valve to ensure the valve is functioning properly.

2.2 Intake Plenum and Recirculation Air Filters The intake plenum air filter is a roll type filter, utilizing a media which consists of a continuous interlaced filter material rolled on disposable spools. The intake filter is manually advanced. The recirculating air filter is a cartridge-type filter utilized for the mechanical filtration of Control Building air. These filters utilize a filter media which consist of high density glass micro fibers laminated to a glass woven mesh backing.

Rev. 2 Page 10of57

2.3 Emergency Air Filter (CREV) Trains The purpose of the two emergency air filter (Control Room Emergency Ventilation, CREV) trains is to remove smoke and/or radioactive particulate matter and iodine/methyl iodine from the Control Room atmosphere and the outdoor makeup during postulated accident or fire 0

conditions. Each train consists of a dedicated fan, isolation dam pers, NOTE: U1/U2-2obe.spreoda... can be restcled dunng rad/re mode elhW

swffch, high efficiency particulate absorbing (HEPA) filter, and a carbon type adsorber. During Emergency Air Filtering System operation, air enters the filter assembly through the HEPA filter. The air is then directed over the carbon adsorber as it exits the assembly. The CREV fan then directs the air to the recirculation plenum of the Control Room Subsystem.

These HEPA filters are of water repellent and fire resistant construction satisfactory for operations at temperatures up to 2500F. The filter media is glass type media designed with a filtering capacity of 99.97% for 0.3 micron particles.

Each train's filter bank consists of two HEPA filters in parallel.

The function of the carbon type filters is to remove iodine, or its organic compounds, which may be contained in the Control Room or outdoor air. Each train's adsorber bank consists of six horizontal trays of granular activated carbon, impregnated as required to provide the needed iodine and methyl iodide removal efficiency. The trays are designed so that the carbon can be completely removed without destroying the integrity of the cell.

The emergency air filters are equipped with run time meters located in the Unit 2 Cable Spread Room, in the MCC compartment for the emergency recirculation fans. The tag number for the 2A fans is 2-2CA-C23-ETM and for the 2B fan is 2-2CB-C44-ETM.

I SD-37 Rev. 2 Page 11 of 57 1

2.4 Ventilation Fans The majority of the ventilation fans contained in the Control Building Heating, Ventilation, and Air Conditioning System are identical with the exception of size and capacity. These fans are in-line, direct driven, axial flow type with the motor and fan housed within the air ducting. These fans are driven by enclosed, air-over type motors cooled by the air circulating inside the ventilation duct containing the fan unit. The booster fans for the Control Room air conditioning condenser area are belt-driven propeller type fans, while the computer room air conditioning air handlers are squirrel cage type.

The ventilation fans are designed such that when the fan is started, the fan's dampers receives an OPEN signal, and when the damper's limit switch indicates OPEN, then, the fan motor receives a START signal. This ensures the fan will not start under a shutoff head (no flow) condition, which could result in damage to the fan.

2.5 Control Room Ventilation Air Conditioning Units The recirculating ventilation air conditioning units each consist of an air cooled condensing unit, a subcooling heat exchanger/condensing unit and a direct expansion cooling coil (evaporator) assembly. The condensing units provide for the initial heat removal (cooling) of the refrigerant used in the system.

This refrigerant is then directed to a subcooling heat exchanger where it can be further cooled by the refrigerant of the subcooling condensing unit. The original refrigerant is then routed to the expansion valves of the (evaporator) cooling coils located in the appropriate ventilation fan suction flowpath where the air is cooled and dehumidified prior to Control Room introduction.

The cooling air for the main condensing units is provided by four fans mounted internal to each of the three units. Two booster exhaust fans are located in the condenser area to provide additional cooling for the three primary air cooled condensing units. These booster fans maintain the ambient temperature at an acceptable level for efficient condenser performance. Failure of the two booster fans does not affect operability of the condensers.

Each condensing unit includes an air-cooled subcooling condenser unit to boost the capacity of the condensing unit. The capacity of each system is increased from approximately 38 to 40 tons by cooling the liquid refrigerant in a heat exchanger served by the subcooling condensing unit. Failure of the subcooling condensing system does not affect operability of the primary condensing unit. The subcooling system is normally turned off.

2.6 Control Room Ventilation Subsystem Heating Coils Heating coils are provided in the discharge ducting of the cooling coil assemblies for each recirculating ventilation air conditioning unit. These heating coils are operated during low temperature conditions and are controlled by their respective thermostats in the Control Room back panel areas. The individual heating coils are finned, tubular, resistance heating elements rated at 51,180 Btu/hr.

2.7 Control Building Instrument Air Compressors Two safety related, 100% redundant instrument air compressors, complete with receiver tanks, are provided to supply the air requirements for the Control Building Heating, Ventilation, and Air Conditioning Control Air System. The compressors are belt driven by a 480 VAC, 3 phase motor and the receiver tanks are equipped with automatic drain traps. The discharged air is cooled and dried by a refrigerated air dryer which is also provided with an automatic drain trap. After the air dryer, part of the air is reduced to 20 psig and routed to the Control Air System via an air filter, while the rest is reduced to 80 psig and routed to the test cylinder of the exhaust tornado dampers and the actuators of the four isolation dampers of the Control Room Ventilation Recirculation System.

The intake air for the two instrument air compressors is taken from filters inside the return air plenum which is inside the Control Room habitability envelope.

This control air is used in regulating the thermostats in the Control Room.

As these thermostats cycle, instrument air is bled off. Therefore, because the instrument air is clean; radioactive or toxic gases will not be introduced into the Control Room.

3.0 INSTRUMENTATION AND CONTROL Table 37-1 is a list of monitoring instrumentation and locations associated with the system. Table 37-3 is a list of the Instrument and controls setpoints which provide trip functions in the system.

3.1 Component Controls 3.1.1 Air Conditioner Condenser Area Booster Exhaust Fan The Control Room air conditioner area booster exhaust fans are controlled by individual controllers located in the condenser area of the Mechanical Equipment Room. Each controller is provided with a two-position STOP-START, control switch and fan status indicating lights. The booster fans normally cycle on outside temperature to provide extra ventilation to the condensing and air conditioning units for increased efficiency. During low temperature winter periods, the Control Room A/C condenser area booster fans may be manually turned off to prevent cooling the condenser too much, and causing low refrigerant pressure in the A/C system.

3.1.2 Control Building Instrument Air Compressors The Control Building instrument air compressors are controlled by individual three-position, AUTO-OFF-MAN control switches located on XU-3 panel. Selection of the MAN position initiates a manual start of the associated air compressor. In the AUTO position, the air compressor starts when its associated air receiver pressure decreases to 78 psig.

The air compressor continues to operate to raise receiver pressure to 92 psig, at which time the air compressor will shut down.

3.1.3 Intake Plenum and Recirculation Air Filters The original automatic control of the intake plenum filter is no longer functional. The recirculating filter is a cartridge-type filter. Both are manually advanced/replaced on a regular basis by Maintenance personnel.

Control Building Washroom Exhaust Fan The Control Building Washroom exhaust fan is controlled by a two-position, STOP-START control switch (U-2 RTGB) and starts and stops the same as the Cable Spread Room fans. This fan will trip and its exhaust damper will close on initiation of the Emergency Air Filtration (CREV) System or after a chlorine signal.

3.1.5 Manual Operation of CREV Isolation Dampers The CREV Emergency Air Dampers, 2-VA-2A/B/C/D-EAD-CB are equipped with Instrument Air Vent Valves which allow the instrument air line to be isolated from the dampers, then the dampers can be manually operated. Note that this operation should only be performed under an LCO with appropriate cautions given to the Control Room that the control switches to the EAF System and the automatic activation capabilities have been rendered inoperable.

3.1.6 Computer Room Split A/C System Each computer room HVAC system is a split system that is continuously operated.

There are no RTGB control switches and the system does not trip due to radiation, chlorine, or smoke signals. The units are thermostatically controlled to maintain 680F in the computer room.

3.1.7 Smoke Removal Plan The automatic smoke protection mode is intended to prevent smoke from a fire outside the Control Room from entering. After a fire in the Control Room, the CB HVAC System has manual smoke removal capabilities. It is detailed on drawing F-04207. When smoke buildup occurs in the Control Room envelope, the personnel doors in the Control Room and mechanical equipment room are opened. Booster fans 1/2-1/2A-BF-CB are verified to be on. The duct access doors immediately up stream from isolation dampers, 1/2-VA-ISOL-DMP-CB, are opened. The isolation dampers are closed. The Control Room supply fans force the smoke into the Mechanical Equipment Room. The negative pressure created by the booster fans draws the smoke out of the Mechanical Equipment Room. After the Control Room is free from smoke, the system is returned to its normal lineup.

NOTE:

Security must be notified when this action occurs because it involves blocking open security card reader doors.

3.2 System Control 3.2.1 Control Room Area Air Conditioning The air conditioning unit for each Unit is controlled from its respective XU-3 panel using control switches 1-VA-CS-1 026 and 2-VA-CS-1 028 (Units 1 and 2 respectively). The spare air conditioning unit may be controlled from either unit's XU-3 panel using control switches VA-CS-1 027-1 and VA-CS-1 027-2 (Units 1 and 2 respectively). Operation of each air conditioning unit is identical. The following is an operational description for the Unit 2 air conditioning unit.

The air conditioning unit and its associated supply fan are started simultaneously by the same control switch. Selecting the START position of control switch 2-VA-CS-1 028 energizes solenoid valve 2-VA-SV-1 028 which supplies air to the actuator of the supply fan discharge damper and to Control Room thermostat 2-VA-TC-1 028. The damper fully opens actuating a limit switch to initiate the start of the supply fan and either the heater or the air conditioning unit as called for by the thermostat.

The "FAN ON" indication is actuated by an air flow switch located in the fan discharge ducting.

The spare air conditioning unit may be placed in service as a replacement for either unit's air conditioning unit. Start of the spare unit can only be initiated from the XU-3 panel associated with the shutdown air conditioning unit. The spare air conditioning unit is then started in the manner previously described. Shutdown of the spare unit requires actuating both control switches simultaneously.

Emergency Air Filtering Trains The emergency air filtering (CREV) trains may be operated in the automatic or manual mode. Each filter train is provided with a three position, STBY-PREF-ON, control switch (2-VA-CS-915A and 2-VA-CS-915B).

Both control switches are located on the Unit 2 XU-3 Panel, with status indicating lights located on each Unit's XU-3 Panel.

1.

An automatic start signal is initiated by any of the following:

a.

Any one of three Area Radiation Monitors (1)

Control Room (Channel 1) 1 mr/hr +.05mr increasing (2)

Control Building Ventilation Intake (Channel 2 or 3) 7 mr/hr

+.05mr increasing

b.

Manual Fire Pull station in the Unit 1 Electronic Equipment Room

c.

Any one Ionization (smoke) detector in the Zone C4 and any one Ionization (smoke) detector in the Zone C5.

d.

Manual Fire Pull Station in the Unit 2 Electronic Equipment Room During normal operation, one filtering train control switch is selected to the PREF (preferred) position and the second train is selected to the STBY (standby) position. The initiation of an automatic start signal places the preferred filtering train in operation.

When a start signal is received, the inlet and outlet Emergency Air Dampers on the preferred filtering train open. In the fully open position, each damper actuates a limit switch to initiate the start of the emergency recirculation fan. If the fan fails to start or trips, a start signal for the standby filtering train is initiated after a 10 second time delay. The starting sequence is identical to that of the preferred train. An air flow switch closes when sufficient air flow is reached to indicate the unit is running. The train will continue to operate until it is secured by operator action from the RTGB.

ISD-37 Rev. 2 Page 27 of57 5

3.2.2

During automatic or manual EAF operation, if chlorine alarm logic, (one out of two twice) is met by the Control Building air intake plenum detectors or by the chlorine loading area (see Figure 37-4 for logic assignment) detectors the emergency recirculation fan trips and associated dampers close. If the Emergency Filtration System is not running, its logic (during a chlorine event), will prevent the Emergency Filtration Subsystem from operating automatically or manually. Shutdown of the filtering train prevents the introduction of chlorine gas into the Control Room area.

A heat (fire) detection system is incorporated into the carbon type filter of each emergency air filter. If a high temperature is detected, the filtering train automatically shuts down. If a radiation or smoke signal is present, the other train will automatically start.

The intake plenum is equipped with two area radiation monitors which are mounted on seismic pedestals in the intake plenum on the intake side of the filters. These monitors provide for radiation detection, and should detection occur the following automatic actions occur: (These same actions occur automatically upon the fire/smoke signals given above.)

The normal intake damper (2L-D-CB) closes The control room washroom exhaust damper (2H-D-CB) closes and the washroom fan (2D-EF-CB) stops The emergency recirculation damper (2J-D-CB) opens The respective inlet/outlet dampers (2A/2C or 2B/2D-EAD-CB) open, and the associated CREV fan (2A or 2B-ERF-CB) starts

"* The Mechanical Equipment Room supply and exhaust dampers close (2K/2T-D-CB) and fans (2F-SF/2E-EF-CB) stop

"* The Cable Spread supply and exhaust dampers close (1 B/2B and 1 E/2E-D-CB) and fans (1A/2A-SF/EF-CB) stop NOTE:

The ventilation for the four battery rooms is not affected, nor is the recirculated air conditioning of the Main Control Room or the computer rooms.

A third area radiation monitor is located inside the Control Room. It is connected to the same logic path as the radiation monitors located in the intake plenum.

I SD-37 Rev. 2 1

Page 28 of 57 1

Selecting a filtering train control switch to the ON position initiates a starting sequence for the CREV fan identical to that initiated by an automatic start signal. However, a manual start does not trip the washroom fan, the mechanical equipment room fans, or the cable spread fans. The filtering train can then be shut down by selecting the PREF or STBY positions, provided an automatic start signal is not present. Also, if a CREV fan is placed in ON, the non-operating fan will not auto start upon receipt of an initiation signal.

3.2.3 Make-Up Air Dampers During normal operation, the normal make-up air damper (2L-D-CB) is open and diverting a nominal 2000 cfm of air from the air intake plenum to the recirculation air plenum, and the emergency make-up air damper (2J-D-CB) is closed. An initiation signal (manual or automatic) to the Emergency Air Filtration System causes the normal make-up air damper to close and the emergency make-up air damper to open.

This signal will also shut the washroom exhaust fan damper (2H-D-CB) thus tripping the fan (2D-EF-CB). The operation of the Emergency Makeup Damper is automatic and cannot be directly controlled by the operator. The Normal Makeup Damper and the washroom damper/fan can be closed by the operator by using control switches on XU-3.

During all modes of operation, all three of these dampers close if a high chlorine level is detected by chlorine detectors located in the Control Building ventilation intake plenum or in the area of the chlorine rail car.

3.2.4 Cable Spreading Room Ventilation The Cable Spreading Room supply and exhaust fans are controlled from their respective XU-3 panel using two-position, OFF-AUTO, control switches (1-VA-CS-928-1 and 2-VA-CS-929-1). In addition, individual two-position, NORM-BYPASS, Cable Spread Room 1(2) Vent Emerg.

Bypass key-locked control switches (1-VA-CS-1 586-1 and 2-VA-CS-1586-2) are provided to allow bypassing the detected fire, radiation, or chlorine trips.

SD-37 Rev. 2 Page 29 of 571

The OFF-AUTO control switch initiates the start of both the supply and exhaust fans for the associated Cable Spreading Room. Selecting the AUTO position sets up the fans to auto start on Cable Spreading Room temperature.

High temperature will signal a pressure switch to energize the solenoid valve to allow instrument air to open the dampers. When the dampers are in the fully open position, per limit switches, both fans start. If a fan should fail to start or trip for any reason, its associated damper will close. The fan running indications are provided by a signal generated from an air flow switch located in the discharge ducting of each fan.

The supply and exhaust fans are automatically tripped by the following emergency conditions:

1.

Abnormally high radiation levels (same signal that starts the Emergency Air Filtering System)

2.

Ionization (smoke) detector or manual fire pull station for the associated Cable Spreading Room (Unit 2 also has a flame detector).

3.

High chlorine level (same signal that trips the Emergency Air Filtering System).

If any of the above conditions occur, the fans may be operated by selecting the key-locked bypass switch to the BYPASS position and selecting the associated fan control switch to the AUTO position.

3.2.5 Mechanical Equipment Room Ventilation Fans The Mechanical Equipment Room ventilation supply and exhaust fans are controlled by two-position, STOP-START control switches.

ISD-37 Rev.2 Page 30 of 57

Selecting START initiates opening of a solenoid valve which allows instrument air to open the supply and exhaust dampers. When the dampers reach full open, per limit switches, the fans start. The fan running indications are provided by a signal generated from airflow switches located in the fan discharge duct. The fan trips are the same signals that trip the Cable Spreading Room fans except that the fire detection trip comes from ionization detectors or a pull station associated only with the Mechanical Equipment Room. No bypassing of the trip signals is provided. These fans are not thermostatically controlled. Fans are secured by placing both units control switch (1/2-CS-918) to STOP.

During low temperature winter periods, the Mechanical Equipment Room fans may be manually secured to help the rooms unit heaters maintain the room above 320F, as required by the chlorine detectors.

3.2.6 Battery Room Ventilation Fans The Battery Room ventilation supply and exhaust fans are controlled by two-position, STOP-START control switches.

Operational control of the ventilation fans is identical to that of the Mechanical Equipment Room ventilation fans except that no trip exists for fire detected in the Battery Room or for Control Room radiation or chlorine signals. When the fans are operating, a room thermostat modulates the supply and exhaust vortex dampers to control room temperature. A separate room thermostat cycles the supply duct heater as needed.

Chlorine Isolation Mode The CBHVAC has eight chlorine detectors, four located outside on the west wall of the Service Water Intake structure near the chlorine car, and a pair located in each of the two inlets to the CBHVAC supply plenum. As shown in Figure 37-4, the two locations (four detectors each) are defined as a trip system, with each trip system containing two trip subsystems. Each trip system is designed as one out of two, taken twice. If the trip system logic criteria for either of the Service Water building trip subsystems is met, the Chlorine Tank Car will automatically isolate. If either (or both) trip system's logic criteria is met, the following automatic actions occur:

The normal intake damper (2L-D-CB) closes The Control Room washroom exhaust damper (2H-D-CB) closes and the washroom fan (2D-EF-CB) stops The emergency recirculation damper (2J-D-CB) closes or remains closed All CREV inlet/outlet dampers (2A/2C or 2B/2D-EAD-CB) close or remain closed, and the CREV fans (2A or 2B-ERF-CB) stop or are prevented from starting The Mechanical Equipment Room supply and exhaust dampers close (2K/2T-D-CB) and fans (2F-SF/2E-EF-CB) stop The Cable Spread supply and exhaust dampers close (11B/2B and 1E/2E-D-CB) and fans (1A/2A-SF/EF-CB) stop The ventilation frrhcrciirhtt COFJ-sOLBIL-DIN G TR[ P SYSTE M

I SD-37 Rev. 2 Page 32 of 57 1 3.2.7

4.0 SYSTEM OPERATION 4.1 Normal Operational Relationships The system is designed to operate on a continuous basis with minimal Operator action, due to automatic control (temperature, radiation, chlorine, smoke).

Within the instrument air/pneumatic controls subsystem, there are provisions for manually isolating certain components to allow maintenance work without shutting down the entire Control Room A/C subsystem.

4.1.1 Normal System Flowpaths The normal system flowpaths provide for once through ventilation of all areas except the Control Room. These areas are both Cable Spread Rooms, all four Battery Rooms, the Mechanical Equipment Room and the Elevator Machinery Room. The ventilation air for these rooms comes from outside via two supply plenum tornado check valves, the supply plenum filter, and individual room supply dampers and fans. The air is exhausted directly outside via exhaust fans and dampers and the exhaust tornado check valves.

The Control Room Ventilation Subsystem is operated in a mode of continuous recirculation and outside air makeup such that temperature control, humidity control, and filtration can be provided. A common filter provides air to individual Control Room heating coils, cooling coils and supply fans. Air within the Control Room envelope is distributed to the Electronic Equipment Rooms, the main control panel area, the Security CAS, etc. Air is drawn from the individual rooms to a common header where it is returned to the common recirculation filter. Each Computer Room has air recirculated to its dedicated air conditioning units to aid in heat removal from these rooms. The computer room air conditioning ductwork also has manual dampers which allow some air from the Main Control Room to be cooled by the computer room air conditioning, then returned to the Main Control Room. During normal operation the Control Room outside makeup air is lost via building/system leakage and approximately 350 SCFM through the Washroom exhaust fan. Normal make-up is approximately 2000 SCFM via air conditioning fans. This difference in loss and make-up, results in a positive pressure being maintained in the Control Room. This positive pressure is a design feature, but it is not required during normal operation.

SD-37 Rev. 2 Page 33 of 57 1

4.2 Abnormal Operation 4.2.1 High radiation System Flowpaths with Detected High Radiation or Fire detected at the Control Building intake plenum, or in the Control Room OR smoke detected in both Control Room Electronic Equipment Rooms OR the pull station tripped in either units' Electronic Equipment Room will place the Control Room Ventilation Subsystem into a mode of FILTERED recirculation and outside makeup. In this mode, the washroom exhaust fan trips and damper closes, the emergency recirc damper opens, the normal make up damper closes, and an emergency air filtration train starts. This provides approximately 1500 SCFM of make-up air and approximately 500 SCFM of recirculated air which passes through charcoal adsorbers and is filtered via HEPA units. With the 1500 SCFM of make-up air, and leakage as the only exhaust path (normal exhaust is isolated),

the Control Room is maintained at a positive pressure relative to the outdoor atmosphere. The filtration units contain charcoal for iodine removal and HEPA filters for particulate and smoke removal.

Smoke detected in, or manual pull station tripped in the Mechanical Equipment Room, either units' Cable Spread Room, or high radiation detected in the Control Building intake plenum or the Control Room causes the Mechanical Equipment Room and Cable Spread Room ventilation dampers to shut and trip the associated fans. The Cable Spreading Room fans are equipped with a bypass switch on the XU-3 panel to allow the bypassing of protective interlocks during periods of extreme emergency (high temperature in the room(s)).

The Battery Room fans are not affected by any of these signals. Neither is the Control Room air conditioning or its fans.

ISD-37 Rev. 2 Page 34 of 571

System Flowpaths with Detected Chlorine Chlorine intrusion detected in the Control Building intake plenum or at the chlorine rail car (SW structure wall) will cause the Control Room Ventilation System to isolate all outside ductwork penetrations and operate in a strict recirculation mode until the chlorine signal can be reset. Self Contained Breathing Apparatuses (SCBAs) are located in the Control Room should this mode fail or be necessary for an extended period of time. This same chlorine intrusion signal will cause closure of the Unit 1 and Unit 2 Cable Spreading Room and the Mechanical Equipment Room ventilation dampers. This in turn will cause stopping of the associated fans. The Cable Spreading Room dampers are equipped with a bypass switch located on the XU-3 panel to allow restarting the fans with a chlorine signal present if high Cable Spread room temperatures develop.

The Battery Room fans are not affected by any of these signals. Neither is the Control Room air conditioning or its fans.

4.2.3 Control Room Emergency Ventilation The Emergency Air Filtering System provides the additional filtering and positive pressure necessary to maintain habitable conditions within the Control Room area during emergency situations. The Emergency Air Filtering System consists of two filtering trains, each consisting of an emergency air filter and recirculation fan. One filtering train is required for system operation with the other serving as the 100%

redundant standby train. For a chlorine event, the CREV does not operate. The Control Room is isolated (no positive pressure).

To restore CBHVAC after a CREV initiation, once the initiation signal is reset, the system is realigned per OOP-37.0, which requires completion of a table to determine the effect of the run on the charcoal bed and required actions. The required actions are based on the reason for initiation and run time.

I SD-37 Rev. 2 Page 35 of 57 1 4.2.2

Failure of the CBHVAC System including the Emergency Filtration Train to function as required on a high radiation, fire, or chlorine alarm, could result in a Control Room evacuation and plant shutdown from outside the Control Room.

4.2.4 Control Room Air Conditioning Control Room air temperature is required to be less than 760F. If it exceeds 76oF, four hour trending of temperature is required. If Control Room temperature exceeds 840F, around-the-clock troubleshooting of the Control Room HVAC System shall commence until temperature is restored within the normal band (<760F). On a sustained loss of Control Building Ventilation (e.g Station Blackout) all Control Room backpanel cabinet doors are required to be opened. This is performed to minimize heating of the electronic equipment in these panels until the necessary emergency diesel generator crossties can be made and the Control Room A/C restarted.

4.2.5 Control Building Chlorine Isolation The Control Room, Cable Spread Rooms, and the Mechanical Equipment Room are isolated on a chlorine signal. This design provides a Control Room which will remain habitable during a chlorine tank car rupture, allowing Operators to safely control the plant during the event. While it is desired they remain off during a chlorine release, the Cable Spread fans can be restarted if temperatures in those rooms reach their annunciator setpoints (101 °F). If the Control Room chlorine protection mode is lost, Operations may have to use SCBA and/or leave the Control Room to safely operate the plant. Restoration of the CBHVAC after a chlorine isolation initiation is found in OOP-37.

I SD-37 Rev. 2 Page 36 of 57

Battery Room Ventilation Battery capacity and lifetime are affected by temperature. The Battery Rooms should remain above 77°F at all times. For every 3oF drop in electrolyte temperature, the specific gravity drops by one point. If the Battery Room ambient temperature is <71oF a WR/JO must be written to monitor battery cell temperatures. If the cell temperature is below 65oF a WR/JO will be required to set up emergency heating in the room. If the cell temperature drops below 60°F, the battery must be declared INOP. If the Battery Room ambient temperature is >1 10oF, a WR/JO must be written to obtain cell temperatures and notify the system engineer. High cell temperatures are not an operability concern and no LCO applies, but it is a battery lifetime concern.

Ventilation is required during the equalization of the batteries to prevent the generated Hydrogen gas from reaching its explosive limit. Therefore, battery room ventilation failure could impact the ability to charge/equalize the batteries, unless alternate methods of ventilation/dilution are provided.

4.3 Interrelationships With Other Systems The Control Building HVAC Control Air System is supported by the AC and Electrical Distribution Systems. Power for major components comes from 1(2)CA and 1(2)CB [480 Vac panel fed from E5(E7) and E6(E8)]. 120 Vac power for dampers comes from 120 volt panels 1(2)A, B, C, and D (also fed from E-bus power).

The chlorine detectors at the chlorine loading area are powered from 120 Vac panels 2A-SW (Div I) and 2B-SW (Div II) (E7/E8). The chlorine detectors in the Control Building intake plenum are powered from 120 Vac panels 2C (Div I) and 2D (Div II) (2E7/2E8). If power is lost to the chlorine detectors or its logic, it will not cause a chlorine isolation (for the division that lost power).

The system will also not start in the fire or radiation mode if the Fire Detection System or ARM System loses power (again, for that division).

ISD-37 I

Rev. 2 Page 37 of 571 4.2.6

The Control Building HVAC Control Air System is provided with two safety related instrument air compressors (powered from 1 CA and 2CA). These air compressors provide control air for the HVAC pneumatic controllers. If all control air is lost, the dampers will fail to the chlorine detected mode except the EADs which fail as-is and the normal intake damper (2L-D-CB) which fails open. Also, ventilation and A/C to the Control Room will be lost. On loss of power to the solenoid valves, the Control Room isolation dampers fail closed.

5.0 RELATED INDUSTRY EVENTS 5.1 IE 82-43 IE Information Notice No. 82-43 "Deficiencies in BWR Air Filtration/Ventilation Systems" dated November 16, 1982, described deficiencies in prefilters and HEPA filters in safety-related and non-safety-related ventilation systems. It stated that these deficiencies would most likely be avoided if the systems were installed, maintained and tested in accordance with Regulatory Guides 1.52 and 1.140.

5.2 PM 79-094 Plant modification 79-094 on Unit 2 was used to add INOPERABLE annunciators to the Control Building emergency recirculation fan circuits 2A-ERF-CB and 2B-ERF-CB. The INOPERABLE annunciator signals whenever the corresponding recirculation fan is inoperable due to a loss of power to the fan or the fan overloads tripping open.

5.3 SER 11-92, Consequences of Disabled Dampers INPO Significant Event Report (SER) 11-92 summarizes four industry events involving ventilation and fire dampers that were disabled by maintenance activities or plant modifications. The consequences of these damper mispositioning events were ventilation configurations that would not support the required operation of important plant equipment. These events are significant because disabled dampers resulted in unavailability of safety systems.

The importance of dampers, fans and other ventilation system equipment in supporting the operation of safety equipment is not always readily apparent from plant documents and drawings. Effective planning of activities that involve disabling dampers includes work area/system walkdowns and visual inspections to identify possible conflicting interactions.

I SD-37 Rev. 2 Page 38 of 57

Because dampers in plant ventilation and fire protection systems function similarly to valves in piping systems, the mispositioning of dampers often exhibit causal factors similar to those involving valve mispositioning. The frequency of positioning errors is significant even though initiatives have been undertaken that are intended to reduce these events. Human error continues to be the predominant cause of mispositioning events. By understanding the factors that influence human performance, improved administrative controls and personnel self-checking awareness can be utilized to prevent human error.

5.4 CBHVAC Instrument Air Dryer - Removal From Service The BNP Control Room air conditioners tripped on 1/17/94 due to low pressure in the instrument air supply line. Pressure gauge 2-VA-PI-1636 indicated 5 psig; 20 psig is normal. This same line supplies instrument air to the Control Building HVAC dampers. LCOs A-2-94-0073 and A-1 0075 were initiated in accordance with Technical Specification 3.7.2 because the components of the 2A and 2B Emergency Air Filtration Systems were rendered inoperable. The CBHVAC Instrument Air Dryer, located in the 70' Mechanical Equipment Room, was isolated (valves 2-VA-IV-2633/2636) and the bypass valve opened (2-VA-IV-2632). This restored the normal instrument air supply pressure to the CBHVAC System. The above LCOs were then canceled, and tracking LCO T2-94-0079 was initiated.

The air dryer failure was found to be due to a low refrigerant charge, due to refrigerant leakage over time. This low charge reduced the temperature of the compressed air sufficiently to freeze the condensing moisture in the compressed air line, resulting in blockage of the air line. EER 94-0024 provides justification for operability of the CBHVAC when the dryer is bypassed.

5.5 Control Room NC Subcoolers The Control Room Subcoolers are not required to support any safety-related equipment, nor are they needed to maintain Control Room temperature/humidity below the design values (75oF, 50%). This has been verified by both calculation (OVA-01 04) and by actual plant conditions (Al-1 17, TCF #96-058) with all three subcoolers turned off for the entire summer of 1996. Therefore, the subcoolers should be maintained off to reduce house electrical load.
