Docket No. 50-206 JAN 17 LICENSEE:
Southern California Edison Company FACILITY:
San Onofre Nuclear Generating Station, Unit 1 (SONGS-1)
SUBJECT:
SUMMARY
OF MEETING TO DISCUSS APPENDIX R (FIRE PROTECTION) AT SONGS-1 On November 14, 1985 the NRC staff met with licensee representatives to discuss the Appendix R compliance review for San Onofre, Unit 1. Discussions during the meeting centered around the area-by-area review for compliance with Section III.G of Appendix R, the design of the dedicated shutdown system (DSS), a review of exemptions from NRC requirements that have been submitted or are pending, and a discussion of possible deviations from NRC guidance.
The licensee committed to submit additional information to the NRC in response to specific questions regarding the DSS design and to clarify certain exemption requests.
A list of attendees is provided as Enclosure 1. Copies of handouts provided are included as Enclosure 2.

Reactor Coolant System Cables for the following components:
primary system temperature transmitters pressurizer pressure transmitter pressurizer level transmitter Main Steem System (MS$)
Cables for tne follaping components*
steam generator level transmitters Cables for the dedicated snutdown system operation of pressurizer heater group 0, and the PURVs and their associated block valves will also be routed tnrough this tire area/zone.
The fire protection features provided for the protection and separation of safe shutdown systems within the fire area/zone do not meet the separation requirements of 10CFR5O Appendix R, Section 11I.6.2.
The dedicated shutdown system will be used to achieve and maintain cold shutdown in the event of a fire in the fire area/zone.
Operator action will be taken to locally control certain valves required for hot standby.
Operator action will also be taken to deenergize offsite and normal onsite power sources to prevent and mitigate spurious equipment operation.
An exemption request for the lack of area-wide suppression/detection per the requirements of Sections Il.G.3 will be provided.
Cables and equipment for the dedicated shutdown system which are routed through this fire area/zone will be protected by a 3-hour rated fire barrier.
The interruption of seat injection and seal cooling to the reactor coolant pumps, for the period required to initiate seal injection from the dedicated shutdown system, nas been evaluated and determined to be acceptaole (26).
The loss of auxiliary feedwater flow, for the period required to initiate auxiliary feedWdter flow from the dedicated shutoown system, has been evaluated and determined to be acceptable (24,25).

Damage to the cables for atmospheric steam dump valves CV-?
and CV-79 could cause the valves to spuriously open.
Spurious actuation of the valves, until operator action is taken to deenergize and close the valves, has been analyzed, and will not result in unacceptable consequences (24.25). The redundant steam dump valves CV-76 and CV-78 will remain available for dedicated shutdown system operation.
Damage to cables for the reactor vessel head vent valves and pressurizer hiqh point vent valves could cause the spurious actuation of the two redundant high/low pressure interface valves in each line.
Spurious actuation of these valves, until operator action is taken to deenergize and close the valves, has been analyzed, and will not result in an unacceptable consequences (24,25).
Damage to cable for primary plant makeup water control valve FCv-1102A could cause the valve to spuriously actuate, allowing primary plant water to be supplied directly to the charging pump suction.
Spurious actuation of this valve, until operator action is temen to deenergize and close the valve, has been analyzed and determined to be acceptable (27).
Uamage to cables for boric acid supply valves FCV-ilU28 and CV-334 could cause these valves to spuriously open, allowing concentrated boric acid to be supplied to the charging pump suction. Operator action will be required to close manual valves to isolate these lines.
Damage to cables for the containment spray control valve CV-I14 could cause this valve to spuriously open. Containment spray will not be inadvertently initiated, as the refueling water pumps will not be spuriously actuated by a fire in this fire area/zone.
