, Durins the 1979 Refueling Outage, Type B and C Local Leak Rate Tests (LLRT) will Le performed to ccmply with Tech. Specs. Sections 4.7.A.2.e and 4.7.A.2.F and Appendix J to 10CFR50. This will involve subjecting potential leak paths, j i.e. containment penetrations (Type B Test) and containment isolation valves (Type C Tests) to the same test conditions that would occur post-LOCA.
Conducting local leak rate test (LLRTs) allow discovery and elimination of leak paths thru the containment without performing the Integrated Leak ,
Rate Test (Type A Test) each. refueling outage. ,
Since the primary concern in the containment leakage test program is tot-al containment leakage, no specific acceptance ' criteria is defined for an ' individual Type B or Type C LLRT (excluding MSIVs). However, the logis-tics used in determining an unsatisfactory LLRT encompasses several factors.
The valve design, size, service, etc. are considered in order to maintain .
the total containment penetration leakage within the acceptance criter- ,
ia without imposing an unrealistic -leakage rate limit on an individual valve.
