Joseph M. Farley Nuclear Plant - Unit 2 Leakage Outside Containment As required by NUREG-0737, item III.D.1.1 and the Joseph M. Farley Nuclear Plant Unit 2 Safety Evaluation Report, Supplement No. 5, the below listed leakage rates of systems outside containment are submitted.
The allowable leakage rate levels given are those levels at which Alabama Power Company feels additional investigation and/or further leakage re-duction would be advisable.
1.
Containment Spray System. Allowable leakage is 0.25 GPM, Unit 2 leakage is 0 GPM (3 drops / min.).
2.
High Head Safety Injection (CVCS System). Allowable leakage is 1.0 GPM, Unit 2 leakage is 0 GPM.
3.
Low Head Safety Injection (RHR). Allowable leakage is 1.0 GPM, Unit 2 leakage is 0 GPM.
4.
Containment Atmosphere Sample System. Allowable leakage is 100 SCCM, Unit 2 leakage is 16.7 SCCM.
5.
Sampling System. Allowable leakage is 0.25 GPM, Unit 2 liquid leakage is 0.0006 GPM.
Allowable VCT gas leakage determined by soap bubble (Snoop) leak check is 500 SCCM, Unit 2 leakage is 0 SCCM.
6.
Waste Gas System. Allowable leakage is 500 SCCM. Unit 2 leakage is 0 SCCM.
AoW 7.
All relief lines of systems covered under the leakage assess-3 ment program are sausfactory.

subiect Review of Draft Letter 03 "'
August 19, 1981 FNP-81-1008 From W. G. Hairston, III To Mr. O. D. Kingsley, Jr.
At Farley Nuclear Plant In response to your letter NT-81-0471 (A4.02) dated August 12, 1981 we have the following recommendation.
Change the allowable leakage for Low Head Safety Injection (RHR) from 0.25 GPM to 1.0 GPM. The leakage assessment procedure results for this system were substantiated by the Operations Group performance of a surveillance test procedure (FNP-2-STP-9.0), "RCS Leakage Test", which lists its acceptance criteria as 5 1.0 GPM unidentified leakage and i 10.0 GPM identified leakage.
All other information presented in the draft letter appears appropriate.
If you have any questions, please advise.
