TO GENERIC LETTER NO. 88-20, SUPPLEMENT NO. 4 INDIVIDUALPLANT EXAMINATIONS FOR EXTERNAL EVENTS NINE MILE POINT NUCLEAR STATION, UNIT NOS.

1 and 2

(TAC NOS.

H83645 AND H83646)

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, "Procedural and Submittal Guidance for the Individual Plant Examination of External Events (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 dated June 29, 1992, that your scheduled completion dates did not support the Commission's goal of closure on the severe accident issue by mid-1994.

You subsequently provided additional justification for the Unit 1

IPEEE completion date and informed us of your revised date for completion of the Unit 2 IPEEE.

We have reviewed your letter dated September 18,

1992, and, although later than the staff would have preferred, we have determined that your schedules are acceptable.

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

Sincerely, Original signed by:
