1.0 INTRODUCTION
l This report has been prepared by Southern California Edison-San Onofre Nuclear Generating Station, Unit 1, in accordance with the requirements of 10CFR50 Appendix R, Section III.G, to demonstrate the capaDility to safely shut down the plant in the event of fire. The report is divided into five sections, including this introductory section. Tne second section of the report details the methodology used to perfonn the compliance evaluation. Figures wnich show the division of the plant into fire areas and fire zones are included in Section 3 of the report. The fourth section provides the detailed evaluation of the compliance of each fire area / zone to the requirements of 10CFR50, Appendix R, Section III.G. Tne final section lists the references used in the peformance of the evaluation. The evaluation is based on the systems required for safe shutdown in the event of fire as defined in Revision 1 to the Updated Fire Hazards Analysis for San Onofre Nuclear Generating Station, Units 1, 2, and 3, except as noted below:
- the consideration of the effects of the spurious operation of components which define the high/ low pressure interface on the primary system;
- the consideration of the effects of the spurious operation of O
v boundary components of support and secondary systems;
- the inclusion of the dedicated shutdown system;
- the conceptual design for the dedicated shutdown system, as submitted to the Nuclear Regulatory Commission on April 24, 1984, and Revision 1 to the conceptual design (submitted in response to NRC questions);
- the review of normal, alternate, and dedicated shutdown systems against the functional requirement of 10CFR50, Appendix R, Section III.L.
For the purpose of this evaluation, tne plant fire areas and zones, as defined in Revision 1 to the Updated Fire Hazards Analysis, have Deen revised to reflect the division of the plant into those fire areas / zones whose boundaries may be expected to contain a fire due to the in situ comoustibles. The revision of the plant fire area / zones may be summarized as follows:
- A new fire area was created for the roof of the power block (1-PB-56-33).
- The yard, formerly fire zone 1-AB-14-2J, has been redefined as a zone of the yard fire area (1-YD-14-4D).

SAN CNCFRE NUCLEAR GENERATING STATION - UNIT 1 10CFR50 APPENDIX R, SECTION III.G CCMPLIANCE EVALUATION n V 2.0 METHODOLOGY The evaluation of plant compliance to 10CFR50, Appendix R, Section III.G requires that the plant demonstrate that: a single fire will not damage redundant systems required for safe shutdown; damage to associated non-safety circuits of concern which could prevent operation or cause maloperation due to hot shorts, open circuits, or shcrts to around will not result in the loss of redundant systems required for safe shutdown. In accordance with the guidance provided by Generic Letter 81-12, plant compliance to these requirements was analyzed by the perforwance of the following tasks: Development of the Safe Shutdown Equipment List Development of the Minimum Required Circuits List Safe Shutdown Circuit Routing Comon Power Supply Analysis Comon Enclosure Analysis Circuit Analysis Review of Fire Area / Zone Boundaries Evaluation of Compliance to 10CFR50, Appendix R, Section III.G The criteria, assumptions and methodology used to perform each of these tasks are outlined below. 2.1 Criteria The criteria used to perform the evaluation are as follows:
- The plant shall be evaluated against the requirements of 100FR50, Appendix R, Section III.G, Fire Protection of Safe Shutdown Capability. Clarification of the requirements of Appendix R shall be obtained from the following guidance documents:

- Plant transients resulting from the most severe of the following spurious operations shall not result in an unrestorable condition (5): ;
- a. The safe shutdown capability should not be adversely affected by l any one spurious actuation or signal resulting from a fire in any i plant area. l
- b. The safe shutdown capability should not be adversely affected by a fire in any plant area which results in the loss of all automatic function (signals, logic) from the circuits located in
- the area in conjunction with one worst case spurious actuation or l t signal resulting from the fire. I
- c. The safe shutdown capability should not be adversely affected by a fire in any plant area which results in the simultaneous spurious actuation of all valves in high/ low pressure interface i
lines. I 2.2 Assumptions l The assumptions used to perform the evaluation are as follows:
- The plant is assumed to be at full power operation.
- Plant accidents or the most severe natural phenomena are not i postulated to occur simultaneously with the fire or subsequent plant shutdown.
4
- The fire occurs concurrent with a loss of offsite power. Power for the operation of safe shutdown equipment is available from the 4 emergency diesel generators, or the dedicated diesel generator.
- Simultaneous fires in separate fire areas or fire zones are not
- postulated.
- Manual actions may be taken to locally control systems / components which are nomally automatically controlled.
- Loss of piping and passive components (i.e. check valves, tanks, etc.) is not postulated to occur as a result of the fire.
- The reactor cavity cooling fans are required to provide coolina for l the source range monitors. Existing procedures provide required cooling for other safe shutdown components in the event HVAC is lost, by natural ventilation through openings, open doors, and the use of portable exhaust fans.

& r.- m - -. - ' - 1+ -L SAN ONOFRE NUCLEAR GENERATING STATION - UNIT 1 10CFR50 APPENDIX R, SECTION III.G COMPLIANCE EVALUATION O - Offsite power was assumed to be available for those spurious operations which could adversely affect safe shutdown of the plant, until such time as operator action is taken to isolate the offsite power. No credit is taken for offsite power availability if the spurious actuation could result in assisting plant shutdown.
A three phase to three phase hot short between 480V AC power cables is not considered credible. 2.3 Development of the Safe Shutdown Equipment List The systems and components needed for post-fire shutdown are those systems necessary to perfom the shutdown functions defined in 10CFP50, Appendix P, Section III.L, Alternative or Dedicated Shutdown Capability. These guidelines also apply to the systems needed for normal post-fire shutdown capability (3). The acceptance criterion for post-fire shutdown systems is also defined in 1 Section III.L: During the post-fire shutdown, the reactor coolant system process variables shall be maintained within those predicted for a loss of normal AC power, and the fission product boundary integrity shall not be affected: 1.e. there shall be no fuel clad damage, rupture of any primary coolant boundary, or rupture of any of the containment boundary. The post-fire shutdown systems shall be capable of achieving the following functional requirements, assuming a loss of normal AC power:
- The reactivity control function shall be capable of achieving and maintaining cold shutdown reactivity conditions.
- The reactor coolant makeup function shall be capable of maintaining the reactor coolant level within the level indication in the pressurizer.
- The reactor heat removal function shall be capable of achieving and maintaining decay heat removal.
- The process monitoring function shall be capable of providing direct
. readings of the process variables necessary to perform and control the above functions.
- The supporting functions shall be capable of providing process cooling, lubrication, etc., necessary to permit the operation of the
- equipment used for safe shutdown functions.
l The systems required for safe shutdown in the event of fire were identified in Appendix A of Pevision 1 to the Updated Fire Hazards Analysis (6), These safe ; ' shutdown systems were reviewed in two stages to insure that the safe shutdown l systems identified were in compliance with the Appendix R requirements. l l Impe11 Corporation Report No. 01-0310-1435 2-3 Revision 0 i l
SAN ONOFRE NUCLEAR GENERATING STATION - UNIT 1 10CFR50 APPENDIX P, SECTION III.G COMPLIANCE EVALUATION During the first stage of the review, the safe shutdown systems were evaluated ) against the perfomance goals for shutdown functions listed above. In the i i second stage of the review, the flow path required for the operability of the safe shutdown . system was highlighted on the system piping and instrumentation diagram (P8ID). The highlighted P& ids were then studied to insure that all
. pressure boundaries had been identified and isolated.
Table 2-1, SONGS 1 Safe Shutdown Components, summarizes the results of the
, review of the highlighted P8 ids (17). Each component shown on the highlighted P& ids is listed on the table by system. In addition, the component is categorized as required for hot standby, cold shutdown, alternate shutdown, dedicated shutdown, high/ low pressure interface, or as a spurious operator, based on the following definitions:
Hot Standby Equipment - components which are required to operate to achieve or maintain hot standby conditions. Passive mechanical components, i.e., heat exchangers, are included for completeness. Boundary components, which are normally in the position required to achieve or maintain hot standby, are not included here. These components are addressed as high/ low pressure interface or spurious operation equipment. Cold Shutdown Equipment - components which are required to operate to cooldown from hot standby conditions to cold shutdown, or to maintain cold shutdown conditions. Passive mechanical components, i.e., heat
! exchangers, are included for completeness. Boundary components, which are normally in the position required to achieve or maintain cold shutdown, are not included here. These components are addressed as spurious operation equipment.
Alternate Shutdown Equipment - components used to provide an alternative means of achieving the safe shutdown function, when the , normal systems / components used for safe shutdown in the event of fire are damaged by a single fire. Dedicated Shutdown Equipment - components composing the dedicated shutdown system, up to and including the interface with the normal shutdown components. High/ Low Pressure Interface - equipment which maintains the integrity of the high/ low pressure interface between the reactor coolant sytem and other plant systems. Failure of high/ low pressure interface components could result in a loss of coolant accident. Spurious Operation Equipment - equipment whose inadvertent operation could adversely affect safe shutdown system operation. ! Safe Shutdown Component - components which are classified as required for hot standby, cold shutdown, alternate shutdown, dedicated shutdown, high/ low pressure interface, or as spurious operation equipment.

SAN ONOFRE. NUCLEAR GENERATING STATION - UNIT 1 10CFR50 APPENDIX R, SECTION III.G COMPLIANCE EVALUATION 2.4 Development of the Minimum Pequired Circuits List The minimum required circuits constitute those circuits which, if damaged, could affect the operation of the safe shutdown components identified above. Circuits which are used for indication only, i.e., pump running status, are not considered as required for safe shutdown, as a single failure is not postulated concurrently with a fire. The required circuits were identified through a review of the station elementary diagrams and station circuit schedules in a three step process.
- First, the station circuit schedules were updated using a computerized database manager. Second, the station elementary diagrams were reviewed to determine the circuits which could affect the operation of each safe shutdown component. A block diagram was then developed to illustrate the functional relationships of the circuits for that component. Finally, the circuit schedule was searched to determine the cable identification for each of the circuits on the component's block diagram.
Using the block diagrams, a list of required circuits for each component was developed and input into a computerized database (29). 2.5 Safe Shutdown Circuit Pouting The required circuits for each safe shutdown component were routed by fire area / zone by deterwining, from the raceway layout drawings, the fire area / zone O location of each of the raceways or enclosures through which the circuit was routed. A computerized database of the safe shutdown circuit raceways and enclosures (18) was then used to sort the safe shutdown circuits by fire area / zone. (7-16,18). Field walkdowns were performed for those safe shutdown circuits for which adequate information did not appear in the station circuit schedules or raceway layout drawings (19). 2.6 Common Power Supply Analysis The damage of associated circuits which share a common power supply with components required for hot standby, cold shutdown, or alternate or dedicated shutdown, could result in the loss of power to those safe shutdown components if proper breaker coordination is not provided. The breaker coordination analysis for San Onofre Nuclear Generating Station Unit 1 (20) demonstrates that proper breaker coordination is provided by:
- Buses supplying power to equipment required for hot standby, cold shutdown, or alternate shutdown are properly coordinated.
O I Impell Corporation Report No. 01-0310-1435 2-5 Revision 0
SAN ON0FRE NUCLEAR GENERATING STATION - UNIT 1 10CFR50 APPENDIX R, SECTION III.G COMPLIANCE EVALUATION
- Buses which supply power only to boundary components (high/ low pressure interface or spurious operators) need not be properly coordinated, as these components are chosen such that the failure mode of the boundary valve on loss of power is the desired position for safe shutdown.
- Intertie breakers between the 480V AC switchgear are properly coordinated.
- Train separation between the 4160V AC buses is maintained by racking out the intertie breaker between 4160V buses 1A and 1B.
- Equipment required for dedicated shutdown is supplied power from a dedicated diesel generator. There are no associated loads, as the dedicated diesel generator supplies only those loads required for dedicated shutdown.
2.7 Common Enclosure Analysis The damage of associated circuits sharing a comon enclosure with safe shutdown loads could propagate the fire beyond the boundaries defining the fire area / zone. The propagation of the fire could result from either of two causes: the combustion of the cable insulation, or the electrical overheating n of the cable. The comon enclosure evaluation demonstrates that associated circuits due to comon enclosures will not endanger safe shutdown, as:
- all circuits at San Onofre Nuclear Generating Station Unit 1 are provided with proper fuse or breaker protection per the applicable industry codes (21);
- all cable trays are fire sealed or fire stopped at fire area / zone boundaries (23).
2.8 Circuit Analysis The circuits required for the operation of each safe shutdown component were analyzed to determine how the failure of any of the circuits would affect the operation of the component. The Circuit Analysis (22) postulates each type of fault which could occur in the cable, and using the electrical elementary drawings, determines how the safe shutdown component will operate as a result of the fault. The following circuit failure modes are postulated:
- For component sower cables, three types of cable faults are postulated. T1ese are: open circuits, short to ground, and wire to wire short circuit.

SAN ONOFPE NUCLEAR GENERATING STATION - UNIT 1 10CFR50 APPENDIX R, SECTION III.G COMPLIANCE EVALUATION
- For component control cables, open circuits, short circuits to ground, and wire to wire faults are postulated. For clarity, the analysis documents the resulting position of the controlled i component, e.g. the spurious position of the flow control valve, not i
the solenoid valve operator.
- For instrumentation, three types of cable failures are evaluated.
These are: open circuit and short circuit failure of the instrument signal loads, and the open circuit failure of the instrument power leads. All cable failures were evaluated for their effect on the instrument indication and/or control circuits. 2.9 Peview of Fire Area / Zone Boundaries Section III.G of 10CFR50, Appendix R sets forth the requirement for fire protection of safe shutdown capability on the basis of fire areas. A fire area is defined (3) as that portion of a building or plant that is separated from other areas by boundary fire barriers (walls, floors, or roofs) with any openings or penetrations protected with seals or closures having a fire resistance rating equal to that of the barrier. The division of the plant into fire area / zones is based on an evaluation of the boundaries of those fire area / zones to withstand the hazards associated with the fire area or zone, and to protect the equipment within the fire
,V area / zone from a fire outside the area / zone.
The performance of the 10CFR50, Appendix R, Section III.G Compliance Evaluation on the basis of these fire areas and fire zones requires that an analysis demonstrate that the boundaries of the fire area / zone will limit the consequences of the fire in that area / zone to that area / zone. The Fire Area / Zone Verification (23) establishes the adequacy of these fire area / zone boundaries for preventing the propagation of fire between adjacent fire area / zones. A number of factors were considered in determining the adequacy of a fire area / zone boundary (5, 23). These factors include:
- the construction of the walls, floor, and ceiling of the fire area / zone.
- the size and location of any openings in the walls, floor or ceiling of the fire area / zone.
- the fire loading due to the in situ combustibles in the fire area / zone.
- the protection of the structural steel within the fire area / zone.
- the adequacy of any fire suppression / detection systems in the fire area / zone.

The substantial physical separation will allow the train 1480V electrical distribution system to remain available when the train 2 and train 3 station service transformers are damaged by fire. The train 2 and train 3 480V electrical distribution system will remain available when the train I station service transformer is damaged by fire. Operator action may be required to intertie the 480V switchgear to provide power to components on the redundant switchgear. The intertie cables are routed outside the fire area / zone. Operator action will be required to locally control certain valves required for hot standby located within the fire zone and outside of the fire zone. Damage to cables for charging ptmps G-8A and G-88 and their associated support equipment coulo result in the loss of redundant charing pungs. Cables for charging pep G-86 and its associated support equipment will be rerouted outside the fire area / zone, i Damage to caoles fur RWST isolation valve MuV-883 could cause the valve to spuriously close.

Cables for the auxiliary saltwater cooling pump G-13C are routed in ent>edded conduit through this fire area / zone. The auxiliary saltwater cooling pump will remain available to support component cooling water system operation. The saltwater cooling system is not required to support single phase cooldown. Damage to cables for the temperature control valves for component cooling water flow to the residual heat removal heat exchangers could cause the loss of remote valve control or cause the valves to f all open. Operator action will be taken to locally control component cooling water flow if the residual heat removal system is used to achieve cold shutdown. Damage to cables for the reactor vessel head vent valves and pressurizer high point vent valves, which are routed tnrough this fire area / zone, could cause tne spurious actuation of the two redundant high/ low pressure interface valves in eacn line. Operator action will be required to operate disconnect 2 switches in the penetration area to deenergize and close valves to isolate these lines.

Operator action will be required to manually start the pump at 480V switchgear 1. I Damage to cables for residual heat removal isolation valves MOV-814 and MOV-834 could cause the valves to spuriously open or cause the loss of remote valve control. Redundant isolation valves MOV-813 , and MOV-833 will remain available to isolate these lines. Operator i action may be required to manually open the valves to initiate restNel heat removal. One train of all other systems required for hot standby and cold shutdown will remain free of fire damage.
- Damepe to cables for the reactor vessel head vent valves and pressurfrer high point vent valves, which are routed through 4
this fire area /rone, could cause the spurious actuation of , the two redundant high/ low pressure interface valves in each line. Operator action will be required to operate disconnect switches in the penetration area to deenergire and close these
