SUMMARY
OF APRIL 13, 1983 MEETING RPurple On April 13, 1983, members of the NRC staff met with representatives of Southern California Edison Company (SCE) and San Diego Gas and Electric Company. The purpose of the meeting was to discuss SCE's plans for (1) managing plant retrofit items, and (2) early return to power. Enclosure 1 is a list of attendees. Enclosure 2 are the handouts provided by SCE.
SCE discuss!ed the projected retrofit costs for San Onofre Unit No. 1.
The licensee is seeking senior NRC management endorsement for their integrated implementation plan that is designed to spread-out retrofit items over several reload outages. The proposed plan would extend through the Cycle XII outage (April through June 1990). The implementa tion plan is based on operating the plant on an 18 month fuel cycle and then implementing retrofit items during a three-month outage.
The NRC staff indicated that it supports an integrated implementation approach and that the licensee should submit a formal proposal.
SCE representatives also discussed their plan for early return to power.
The general provisions of the plan are:
- 1. Structures and systems whose failure could cause an accident will be available following a 0.67g earthquake.
- 2. Structures and systems requfred to get to a safe cold shutdown will be available following a 0.67g earthquake.

- 3. Structures and systems not rqquired to get to a safe cold shutdown will be deferred.

-2 April 18, 1983 The NRC staff raised the question whether some Of the backfits other than seismic upgrades would provide a greater increment of safety.
The staff and the licensee plan to investigate this question.

Failure will not impact ability to attain safe cold shutdown Systems o Safety injection o Recirculation o Containment spray o Containment isolation valves and penetrations o
Hydrazine addition a
o Main feedwater pumps and lube oil cooler fans o Control room HVAC
-2 o Backup nitrogen will not be Provided for feedwater pump mini-flow valves (CV 36, 37)

Above systems include piping, equipment, valves and instruments; except where it is required as part of safe shutdown systems Basis:
Reactor coolant pressure boundary, main steam piping and main feedwater piping will be available, therefore an earthquake will not cause an accident. Probability of concurrent earthquake and accident is low.
o Electrical Raceways - completion of modifications Basis:
Electrical raceways have not experienced failure in testing programs. Selected modifications will be implemented to ensure applicability of tests.
PLAN FOR EARLY RETURN TO POWER SAN ONOFRE UNIT 1 Program for NRC Approval o
Maintain dialogue on specific aspects o
Meetings to discuss details as required o
Submittal of plan for early return to power o
NRC approval of plan for early return to power o
SCE will initiate plan for early return to power only after concurrence is obtained on Plan for Managing Plant Retrofit (i.e., long term integrated plant modification upgrade schedule)
