10,kREG~j UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555 June 22, 1992 Docket Nos. 50-361 and 50-362 Mr. R. M. Rosenblum Manager of Nuclear Regulatory Affairs Southern California Edison Company 23 Parker Street Irvine, California 92718

SUBJECT:

REVIEW OF RESPONSE TO GENERIC LETTER 88-20, SUPPLEMENT NO. 4 INDIVIDUAL PLANT EXAMINATIONS FOR EXTERNAL EVENTS - SAN ONOFRE UNIT NOS. 1 AND 2 (TAC NOS. M83671 AND M83672)

Supplement 4 to Generic Letter 88-20 was issued on June 28, 1991, to require each licensee and each Construction Permit holder to conduct an individual plant examination of external events (IPEEE).

Guidance was provided with the generic letter supplement in the form of NUREG-1407, "Procedural and Submittal Guidance for the Individual Plant Examination of External Events (IPEEE) for Severe Accident Vulnerabilities."

The supplement requested a 180-day response (December 26, 1991) that would (1) identify the method and approach selected for the IPEEE, 2) describe the method to be used if it has not previously been submitted for staff review, and 3) identify the milestones and schedule for performing the IPEEE and submittal of the results to the NRC.

Licensees were requested in the supplement to submit the IPEEE results to the NRC for review by June 28, 1994, (3 years after issuance of the supplement) to ensure that the intent of the Commission's Severe Accident Policy Statement will be met by mid-1995.

We have reviewed your letter dated June 9, 1992, submitted in response to Generic Letter 88-20, Supplement 4. We find that your selected IPEEE methods are acceptable. However, your submittal schedule is beyond the NRC's target date of June 1994. This could impact the schedule for closure of severe accident issues. Therefore, the staff requests that you reassess your opportunities for submitting your IPEEE results *on a more expeditious schedule, preferably either in 1994 or early 1995 but no later than June 1, 1995. Also, by doing so, your efforts will more closely reflect the level of safety significance attributed to this effort by the Commission when the goal of closing severe accident issues by June 1995 was established.
