EDWIN I. HATCH NUCLEAR PLANT UNIT 1 ANTICIPATED TRANSIENTS WITHOUT SCRAM IMPLEENTATION SCHEDULE Gentlemen:

Section (d) of 10 CFR 50.62, the final Anticipated Transients Without Scram (ATWS) rule, recuires the submittal of a schedule for completing the recuired plant ATWS modifications within 180 days of the issuance of QA guidance for non-safety related eaufpment. Justification is recuired for a schedule calling for final implementation later than the second refueling outage after the effective date of the ATWS rule (July 26, 1984). Pursuant to those recuirements, Georgia Power Company (GPC) hereby proposes to implement the recuired mudifications in Hatch Unit 1 by the end of its third refueling outage after the ATWS rule effective date.

The proposed schedule is necessary because the timing of the first two fetch I refueling outages relative to the effective date of the ATWS rule allows an insufficient time period for implementation of the recuired modifications. :The rule took effect on July 26, 1984; Hatch I was shut down for a scheduled refuelingf outage on September 29, 1984, only two months later. The unit is currently operating in a twelve month cycle with its second refueling outage following the rule scheduled to begin in November, 1985. By the end of that outage, only 19 months, approximately, will have elapsed after the issuance of the ATWS rule. While the exact nature of the Hatch 1 ATWS modifications has not yet been determined, a reasonable estimated implementation schedule extends well beyond the end of the upcoming outage. An implementation schedule extending to the third outage, 8507260577 85071F DR ADOCK 0500 321 p((

l scheduled to take place in Spring 1987, will allow an orderly implementation of ATWS modifications. This proposal is reasonable in that the third Hatch 1 refueling will end approximately 34 months after issuance of the ATWS rule, while a BWR operating on 18 month cycles could conceivably have 36 months to the end of its second refueling.

Based on the above, CFC considers the proposed schedule to implement this major program to be reasonable and justified. As expressed to you on previous occasions, GPC wishes to resolve licensing issues related to the upcoming November outage as soon as possible. We, therefore, respectfully reouest NRC approval of this schedule within 30 days of receipt of this letter. If you should have any cuestions in this regard, please contact this office at anytime. We will give top priority to responding to your cuestions.

A separate submittal will be made by October 14, 1985, to address the implementation schedule for Hatch Unit 2, which will complete GPC's response to 10 CFR 50.62(d).

Very truly yours,
