.e Docket No. 50-289 Mr. T. Gary Broughton, Vice President and Director - TMI-1 GPU Nuclear Corporation Post Office Box 480 Middletown, Pennsylvania 17057

SUBJECT:

THREE MILE ISLAND NUCLEAR STATION, UNIT 1 - REVIEW OF RESPONSE TO GENERIC LETTER NO. 88-20. SUPPLEMENT NO. 4 - INDIVIDUAL PLANT EXAMINATIONS FOR EXTERF'. EVENTS (TAC N0. M83685)

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 Supplement 4 in the form of NUREG-1407, " Procedural and Submittal Guidance for the Individual Plant Examination of External Events l

(IPEEE) for Severe Accident Vulnerabilities." The supplement requested a response that would a) 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.

Following our review of your initial response to Supplement 4, we informed you by letter on June 29, 1992, that your scheduled completion date did not srpport the Commission's goal of closure on the severe accident issue by mid 1994.

You subsequently informed us of your revised date or provided additional justification for your completion date.

We have reviewed your letter dated September 2,1992, and, although your proposed schedule is later than the staff would have preferred, we have determined that your schedule is acceptable.

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

Sincerely, Distribution:
