(1) Test duration for all valves and penetrations listed will' generally exceed one hour. ,

, (2) Test pressures are at least 50 psig for all~ valves and penetrations

-except MSIV's which are tested at 28 psig. t (3) MSIV acceptable leakage limit is 11.5 scfh/ valve of air.

(4) The total acceptable leakage for all valves and penetrations other

-than the MSIV's is 0.6 La-l' (5)- Local leak tests on all testable isolation valves shall be performed each major refueling shutdown but in no case at intervals greater i than 2 years.

, (6) Local leak tests on all testable penetrations shall be performed each major refueling shutdown but in no case at intervals greater than 2 '

years.

(7) . The personnel air lock shall be tested at intervals not to exceed 6 months.

(8) The personnel air lock door seals are tested at 10 psig after each opening.

i (9) Identifies isolation valves that are tested by. applying pressure between the inboard and outboard isolation valves. Inboard valve is not tested in the direction required for isolation but will have equivalent or.more conservative leakage results.

(10) Identifies isolation valves that are tested by applying pressure between the isolation valve and a manually operated valve such that' the isolation valve is tested in the direction required for ,,

isolation.

4 (11) Identifies isolation valves that are tested by applying pressure between the isolation valves and other system valves. Isolation valves not tested in the direction required for isolation will have equivalent or more conservative results.

(12) The RHR system remains water filled post-LOCA. Isolation valves are tested with water.

.(13) Identifies blind flange that is tested by applying presture between

the flange and a manually operated valve such that the flange is

!- tested in the direction required for isolation.
