b. A combined leakage rate of less than 0.60 L fo and valves subject to Type B and C tests, when r all penetrations pressurized to a {

pressure not less than P,, 37 psig. l ,

APPLICABILITY: MODES 1, 2, 3, and 4. j l

ACTION: ,

With either the measured overall integrated containment leakage rate exceeding 0.75 L or the measured combined leakage rate for all penetrations and valves  ;

SURVEILLANCE RE0VIREMENTS

ExcepY a.s medif{ed by nRC $ppoved exetn/h' cots 4.6.1.2 Jhe containment leakage rates shall be demonstrated at the following test schedule and shall be determined in conformance with the criteria speci-fied in Appendix J of 10 CFR Part 50 using the methods and provisions of ANSI N45.4-1972:

a. Three Type A tests (Overall Integrated Containment Leakage Rate) shall be conducted at 40110 month intervals during shutdown at a pressure not less than P,, 37 psig, during each 10-year service l period. The third test of each set shall be conducted during the shutdown for the 10-year plant inservice inspection; l
