g Gentlemen:
(b y
In accordance with the provisions of 10 CFR 50.90, as required by 10 CFR 50.59(c)(1), Georgia Power Company hereby proposes amendments to Operating Licenses NPF-5 and DPR-57.
The proposed amendment would be to incorporate revised Technical Specifications in response to your July 7, 1980, letter.
The proposed Technical Specifications will strengthen the provisions for assuring continued operability of the control rod drive system during reactor operation by providing surveillance requirements on the scram discharge volume vent and drain valves.
In addition, the pressure relie f valves are added to the existing tables of containment isolation valves and included in the normal surveillance requirements.
The proposed changes in no way alter system design or operation, and thus do not create the possibility of a new accident or malfunction of equipment, nor does it increase the probability of previously analyzed accidents or malfunctions.
Margins of safety are increased by the addition of periodic surveillance on these valves which become containment isolation valves during the time period following a scram and before the scram is reset.
The Plant Review Board and the Safety Review Board have revi2wed the proposed changes to the Technical Specifications and the basis, stated above, for the proposed changes, and have concluded that they do not involve an unreviewed safety question.
Accordingly, we therefore request your review and approval of the proposed changes to the Technical Specifications as shown in the attachments.
Very truly yours, 22'dM Me c03/

Georgia Power Company has evaluated the attached proposed amendment to Operating Licenses zDPR-57 and NPF-5 and has determined that:
a).
of' a new Safety Analysis Report or rewrite of the The proposed amendment does not require the evaluation facility license; b)
.The proposed amendment does not contain several complex' issues, does not involve ACRS review, and does not require an environmental impact statement; c).
The. proposed amendment-does not involve a
