i Unit 2 PBAPS NOTES FOR TABLES 3.7.2 THROUGH 3.7.4 (1)
Minimum test duration for all valves and penetrations listed is one hour.
(2)
Test pressures of at least 49.1 psig for all valves and penetrations except MSIV's which are tested at 25 psig.
(3)
MSIV's acceptable leakage is 11.5 scfh/ valve of air.
(4)
The total acceptable leakage for all valves and penetrations i
other than the MSIV's is 0.60 La.
(5)
Local leak tests on all testable isolation valves shall be performed per 10CFR50, Appendix J requirements.
(6)
Local leak tests on all testable penetrations shall be performed per 10CFR50, Appendix J requirements.
(7)
Personnel Air Locks shall be tested at 6-month intervals.
(8)
The personnel air locks are tested at 49.1 psig.
[
(9)
Identifies isolation valves that may be tested by applying pressure between the inboard und outboard valves.
i (10) Gate valves are tested in reverse direction.
Test acceptable since the normal force between the seat and the disc generated by stem action alone is greater than ten (10) times the normal force induced by test differential pressure except for valves MO-10-31A,B which is 7.97.
This applies to the following valves:
MO-2-74 MO-10-31A, B MO-13-15 MO-10-18 MO-23-15 MO-12-15 (Unit #2)
MO-10-32 (Unit #2)
