HATCH NUCLEAR PLANT UNIT 2 REVISION TO THE AUGMENTED RCS LEAK DETECTION SUBMITTAL Ato IN-SERVICE INSPECTION PROGRAM COMMITMENT Gentlemen:

Our letter to you, dated May 25, 1983, committed Georgia Power Company (GPC) to augmented leak detection requirements for the Plant Hatch Unit 2 reactor coolant system. These new requirements, which were intended to incorporate the surveillance frequencies suggested in NUREG-0313, Rev. 1, Sectio'1 IV.B.1.a.2, were requested by the EC staff as a result of our detecting pipe flaw indications in the RHR and Recirculation systems during the current (111t 2 outage. However, the MC Hatch Licensing Project Manager has indicated, through conversation with GPC staff personnel, that additional commitments were required in order to meet the generic guidance stated in NUREG-0313, Rev. 1.

Therefore, GPC submits the following revisions to the letter of May 25, 1983, and commits to implementation of these revised requirements at the time of unit startup following the current refueling / maintenance outage:

1. Surveillance requirement No. 3 of the May 25 letter shall be revised to require implementation of Technical Specification 3.4.3.2 ACTION c. any time that unidentified leakage increases by 2 gpm over a period of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or less.

2. In addition to the present requirements of Technical Specification 3.4.3.1, operability of at least one of the leakage measurement instruments associated with each sump shall be maintained per Surveillance Requirement 4.4.3.1.b.

These plans will be submitted to ~ the NRC at least three months prior to the start of that refueling outage.

Please contact this office if further information is required.

Very truly yours,
