August 9, 1993 Docket Nos. 50-327 and 50-328 Tennessee Valley Authority ATTN:

Dr. Mark 0. Medford, Vice President Technical Support 3B Lookout Place 1101 Market Street Chattanooga, Tennessee 37402-2801

SUBJECT:

REVIEW 0F RESPONSE TO GENERIC LETTER NO. 88-20, SUPPLEMENT NO. 4 -

INDIVIDUAL PLANT EXAMINATIONS FOR EXTERNAL EVENTS ~- SEQUOYAH NUCLEAR

-i PLANT UNITS 1 AND 2 (TAC NOS. M83674 AND M83675)

The NRC issued Supplement 4 to Generic Letter 88-20 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, i

" Procedural and Submittal Guidance for the Individual Plant Examination of External Events (IPEEE) for Severe Accident Vulnerabilities." The' supplement requested a response 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 i

submitted for staff review, and 3) identify the milestones and schedule for performing the IPEEE and submittal of the results to the NRC.

Following our review of your initial response to Supplement 4, we informed you by letter dated June 24, 1992, that your scheduled completion date did not support the Commission's goal of closure on the severe accident issue by mid-1994.

You subsequently informed us by letter dated September 18, 1992, of your revised date and provided additional justification for your completion date.

We have reviewed your letter dated September 18, 1992, and, although later than the staff would have preferred, we have determined that your schedule is acceptable.

Please inform us of any additional changes to your schedule or methodology.
