Subject:
Docket No. 50-206 Operating License No. DPR-13 Fire Protection Program Review San Onofre Nuclear Generating Station Unit 1 This letter is provided in response to two NRC Staff requests for information concerning their ongoing review of the fire protection program at San Onofre Unit 1. The requests involve:
(1) the schedule for submittal of a revised plan for safe shutdown following a fire, as requested in your letter dated September 14, 1979, and (2) the additional design information for certain items identified in the Fire Protection Safety Evaluation Report dated July 19, 1979.
Our responses to each of these requests are discussed below.
- 1. Response to September 14, 1979 Letter By letter dated January 15, 1979, we submitted for NRC Staff review, a conceptual plan for providing the capability to establish a safe shutdown of San Onofre Unit 1, following a fire in the 4160 Volt Switchgear Room or the Lube Oil Reservoir Area.
The conceptual plan included the use of a charging pump and was not dependent on the Chemical and Volume Control System test pump. As discussed in the NRC Staff's Fire Protection Safety Evaluation Report dated July 19, 1979, the modifications associated with the conceptual plan have been deferred pending completion of the integrated assessment of potential modifications identified by review of station design and operation in connection with the Systematic Evaluation Program (SEP).
Since the information requested in your letter dated September 14, 1979 is dependent upon final engineering of the safe shutdown capability, submittal of that information will be delayed until after the integrated assessment of SEP modifications, at the time when final engineering of the modifications is in progress.
The fire protection criteria included in the enclosure to your September 14, 1979 letter will be used as guidance in the final engineering of the safe shutdown capability.

5.0 AREA FIRE DETECTION SYSTEM 5.1 Design Criteria The area has smoke (ionization) detectors installed above the lube oil reservoir and conditioner, and over the cable trays. This detection system provides an early warning in identifying the commencement of a fire and also acts as backup to Foam and Cable Tray Detection Systems.
The detection system is electrically supervised so that any malfunction will be indicated and alarmed at the local detection panel and in the main control room.
The spacing of the detectors meets the intent of NFPA 72E Appendix A.
The local detection panel is located out of the area being protected.
The detection system indication cannot be reset in the event of trouble or detector alarm, condition until the system has returned to a normal state.
5.2
System Description
When a malunction in the detector circuit or local detection panel occurs, the supervisory function of the system causes a trouble buzzer and indi cation in the local detection panel and MCR to energize.
While the buzzers can be silenced, the trouble lamps cannot be extinguished until the malfunction has ceased.
When one of the pyrotronics DIS 3/5A high voltage ionization detectors in the single loop goes into an alarm condition, a lamp in the base of the detector lights, an alarm bell and zone indicating lamp in the local detec tion panel energizes, and an alarm bell and zone indicating lamp in the MCR energizes. While the alarm bells may be silenced, the lamps cannot be extinguished until the detector in an alarm condition has been reset.
5.3 System Testing After detector sensitivity checks have been conducted, in situ testing shall be conducted to demonstrate responsiveness of the detection sytem to a fire.
Aerosols simulating combustibles from the area shall be released in regulated quantities and the time response of the system recorded.
Normal environmental and air flow conditions will be main tained during testing.

3.1.2 Fire Water Supply Test features will be provided for the fire pumps which meets the requirements of NFPA 20.
An isolation valve(s) will be provided in the above ground cross connection of the yard loop which is routed through the turbine building to prevent the loss of both manual and automatic water suppression due to a single impairment.
A self-actuated pressure valve or a check valve with a parallel bypass valve will be provided in: the Units 2 and 3 connection to the Unit 1 fire water loop.
YARD FIRE LOOP 1.0 GENERAL Modifications to the yard fire loop include the following:
1.1 Intertie to Units 2 and 3 fire water system.
1.2 Isolation valves in turbine building (fire area No. 9).
1.3 Second fire water source for Unit 1 Administration Building hose reels.
1.4 Crosstie and isolation valve between hose reel No. 6 and fire hydrant No. 10.
Each of the above modifications is described below.
2.0 DESIGN CRITERIA 2.1 General Design Criteria 2.1.1 The design objective of the intertie to the Units 2 and 3 fire water system is to provide a separate, independent backup water supply to the existing Unit 1 fire water pumps and salt water cooling water pump.
2.1.2 The primary design objective of the various isolation valves and crossties (1.2, 1.3 and 1.4 above) is to allow removal of portions of the fire water system from service for maintenance without requiring an outage on the entire fire water system.
2.2 Detailed Design Criteria 2.2.1 All valves installed shall be UL listed or FM approved.
2.2.2 Maximum design pressure for the Unit 1 fire system is 165 psig.
2.2.3 All piping and valves shall be installed in accordance with NFPA Standard Nos. 13 and 16.
2.2.4 The intertie shall be designed to prevent flow from Unit 1 to the Units 2 and 3 fire water system.
2.3
System Description
2.3.1 Fire Water System Intertie A check valve shall be installed to allow flow from the Units 2 and 3 fire water system to the Unit 1 fire water system.
-2 During normal operation, the higher pressure in the Unit 1 system will keep this valve closed.
In case of loss of system pressure and loss of the Unit 1 fire pumps, the check valve will open allowing flow into the Unit 1 system. A normally closed block valve will also be provided as a bypass to allow the Unit 1 fire pumps to be used as backups to the Units 2 and 3 fire system, if required.
Both systems are pressurized by the Units 2 and 3 fire water jockey pump. Pressure switches within the system control the operation of the various pumps so that the jockey pump will be actuated first on pressure decay in the system followed sequentially by the Unit 1 fire pump G-11, Unit 1 fire pump G-11S, and finally by the Units 2&3 fire pumps.
The Units 2 and 3 fire pumps are set at lower pressure settings ensuring that the jockey pump will maintain system pressure and that the Units 2 and 3 fire pumps will not start prior to the Unit 1 fire pump.
2.3.2 Additional Isolation Valves Isolation valves shall be installed in the following locations:
2.3.2.1 Block valves shall be installed in lines 8052-3"-KN (BV3) and 856-3"-KN (BV7).
These valves allow isolation of the hose cabinets within the Unit 1 Administration Building, allowing maintenance in the Administration Building without requiring the removal of other portions of the fire water system from service.
2.3.2.2 Block valves shall be installed in line 814-8n-KN between the fire pump discharge line (BV2) and downstream of the branch lines to the lube oil area foam and sprinkler systems (lines 8066-6"-KN, 8072-2"-KN, 843-4"-KN, valve BV1).
These valves permit the separate isolation of each fire pump as well as isolation of the system between BV1, BV7 and PIVH.
2.3.2.3 The second fire water source and block valve (BV6) shall be installed between fire hydrant No. 10 and line 846-3"-KN.
This provides a second fire water source to fire hydrant No.
10 while allowing isolation of fire pump G-11S.
2.4 Testing All modifications to the fire system shall be pressure tested per IFPA No. 13 prior to release for normal operation.
0 3.0 Fire Water Supply Test features will be provided for the fire pumps which meet the requirements of NFPA 20.
A review of NFPA 20 of the National Fire Codes, 1979, has resulted in the identification of the following test requirements:
"A-12-3.1 Weekly Tests A centrifugal pump should be operated every week at rated speed with water discharging through some convenient opening.
This is desirable to make sure of the condition of the pump, bearings, stuffing boxes, suction pipe and strainers, and the various other details pertaining to the driver and control equipment (see 7-5.2.1, 8-6.1, 9-5.2.1 and 9-5.2.6).
When automatically controlled pumping units are to be tested weekly by manual means, at least one start should be ac complished by reducing the water pressure either with the test drain on the pressure sensing line or with a larger flow from the entire system."
n7-5.2.1 Water Pressure Control In the controller circuit there shall be provided a pressure actuated switch having independent high and low calibrated adjustments, and responsive to water pressure in the fire protection system. The pressure sensing element of the switch shall be capable of withstanding a momentary surge pressure of 400 psi (27.6 bars) without losing its accuracy.
Suitable provision shall be made for relieving pressure to the pressure-actuated switch, to test the operation of the controller and the pumping unit.
(See Fig. A-7-5.2.1.)
(a) Each controller for multiple pump installations shall have its own individual pressure sensing line."
"12-3.1 Yearly Test A yearly test shall be made at full capacity and over to make sure that neither pump nor suction pipe is constructed.
Where the water supply is from a public service main, pump operation shall not reduce the suction head, at the pump, below the pressure allowed by the local regulatory authority."
Section 9-5.2.1 referenced in A-12.3.1 above is a duplication of 7-5.2.1 and the other referenced sections of NFPA 20 are not applicable to the Unit 1 fire pumps.
The inspection and testing requirements for the Unit 1 fire pumps are contained in Technical Specification 4.15, Fire Protection System Surveillance. The station procedures which are used to implement these requirements are:
Station Order S-A-2, Fire Protection Operating Instruction S-7-1, Fire Protection Maintenance Procedure S-I-1.55, Fire Water Systems.
-4 Attachments 5A,B,C of S-I-1.55 (enclosed) provide the procedure for performance of the tests as required by NFPA 20.
The guages used in this test are calibrated annually.
By testing the fire pumps using this procedure, the testing requirements of NFPA 20 are met.
