CITY OF DALTON, GEORGIA EDWIN I. HATCH NUCLEAR' PLANT, UNIT NO.1 D0ati NO.60-321 Introduction By letter dated December 2,1981, Georgia Power Company (GPC or the licensee) applied for a change to the Technical Specifications (TSs) appended to Facility Operating License No. DPR-57 for the Edwin I.
The proposed change would update Hatch Nuclear Plant, Unit No.1.
the listing of Primary Containment Testable Isolation Valves.
Background
GPC is installing a Torus Water Drain and Clean-Up System on Hatch Unit 1.
During an early 1981 refueling outage, a portion of the system was installed, and at the same time the TSs were amended to include a manual valve (G51-F016) and a blind flange (G51-D004) as the isolation Late in 1981 during a subsequent outage, valves for the Clean-Up System.
two air-operated valves were installed between the manual valve and the flange; however the flange was removed as the two new valves were con-sidered as an equivalent.
Evaluation We agree that the two air-operated valves are equivalent to the flange that has been removed. These two valves also replace the manual valve G51-F016 as a testable isolation valve; as a consequence G51-F016 has been deleted from TS Table 3.7-4 The licensee has verified that the two new valves are closed and have not been connected to the air supply The valves so that the valves cannot be inadvertently opened, remotely.
have also been " tagged-out", an administrative precaution, that will pre-vent the valves from being manually opened until this proposed TS change is approved. Based on the above, we conclude that the substitution of the two valves for the blind flange and the designation of the two valves in place of G51-F016 as testable isolation valves, is acceptable.
