3.0 LIMITING CONDITIONS FOR OPERATION h.0 SURVEILLANCE REQUIRDEIES (3) ence, prior to and after repair shall be added to the final integrated Icak rate result.
(4) Closure of the containment isolation valves for the purpose of the test shall be accomplished by the means provided for normal operation of the valves.
(5) Test duration shall be at least eight hours and shall include at least 20 sets of data taken at approximately equal time intervals.
In addition, the test shall have a duration sufficiently long l
to accumulate and analyze enough data to verify.
j that the measured leakage rate, at the 957.
confidence level, is less than the acceptance criterion contained in Specification 4.7.A.2(b)(2).
l (6) Each test shall be inanediately followed by a veri-fication test using a known superimposed leak in accordance with Appendix C to ANSI N45.4 -1972.
(
The verification test shall have a duration suf ficiently long to acetamulate and analyze enough data to verify that at the 957. confidence level the measured composite leakage lies within 0.25La of the sum of the superimposed leak rate and the measured overall contairmoent leak rate.
(b) Acceptance Criteria for IPCLT (1) The maximum allowable leak rate Lt shall not exceed 1.2 weight percent of the contained air
, per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> at the test pressure of 41 psig (P ).
