Stolz Operating deactors Branch No. 4 Division of Licensing U. S. Nuclear Regulatory Commission Washington, D.C. 20555 NRC DOCKET 50-321 OPERATING LICENSE DPR-57 EDWIN I. HATCH NUCLEAR PLANT UNIT 1 RECIRCULATION AND RFR SYSTEMS PIPING REPAIRS Gentlemen:

As a result of repairs by means of weld overlay on several Recirculation Systs and Residual Heat Rmoval (RHR) System piping welds which were observed to have unacceptchie ultrasonic indications during examinations conducted during the 1982 maintenance / refueling outage at Plant Hatch Unit 1, Georgia Power Company (GPC) proposes herein an amendment to the Technical Specifications related to reactor coolant leakage detection measures. In addition, augmented inservice inspection of Class 1 austenitic stainless steel piping welds to be examined during the next maintenance / refueling outage is addressed herein.

In accordance with the provisions of 10 CFR 50.90, as required by 10 CFR 50.59(c)(1), GPC proposes an amendment to the Technical Specifications (Appendix A to the Operating License) for Plant Hatch Unit 1. The proposed amendment will incorporate revised specifications for reactor coolant leakage (limiting conditions for operation and surveillance requirements). The proposed changes to the Technical Specifications, enclosed herein, provide:

the addition of an action statment for a 2 gpm increase in unidentified leakage averaged over a 24-hour period; an increase in the monitoring frequency of drywell leakage to at least once per 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />; and, in the event of drywell atmosphere monitor inoperability, the measurment of drywall

gaseous radioactivity and atmospheric particulate at least once per 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

The Plant Review Board has reviewed the proposed changes to the Plant Hatch Unit 1 Technical Specifications, and has concluded that no degradation g gfl'f P

n in plant operation is involved and that operation with the reactor coolant leakage limiting conditions for operation and surveillance requirements, as revised by this submittal, will maintain existing margins of safety. Thus, the proposed changes to the Technical Specifications for Plant Hatch Unit 1 do not increase the probability of occurrence or consequences of a previously analyzed accident or malfunction of equipment important to safety, nor has the possibility of a previously unanalyzed accident or malfunction of equipment been created. Margins of safety have not been decreased.

Georgia Power A Director of Nuclear Reactor Regulation Attention: Mr. John F. Stolz February 10, 1983 Page Two As discussed in Attachment 1, the proposed changes to Plant Hatch Unit 1 Technical Specifications have been evaluated to be a single Class III amendment. Enclosed as the amendment fee is a check for $4,000.00.

With regard to augmented inservice inspection, GPC hereby commits to propose an augmented inservice inspection program to NRC three (3) months -

prior to the next scheduled maintenance / refueling outage. Consideration will be given in the augmented program to the inservice inspection guidance to be addressed by NRC in the Safety Evaluation Report for the Recirculation System and Rift System piping weld repairs performed during the 1982 maintenance / refueling outage.

Should you have any questions in this regard, please contact this office.

J. C. Causey states that he is Vice President of Georgia Power Company and is authorized to execute this oath on behalf of Georgia Power Company, and that to the best of his knowledge and belief the facts set forth in this letter are true.
