b. If any periodic Type A test fails to meet 0.75 L the test schedule for subsequent Type A tests shall be reviewed and approved by the -

Commission. If two consecutive Type A tests fail to meet 0.75 L,, a Type A test shall be performed at least every 18 months until two consecutive Type A tests meet 0.75 L, at which time the above test schedule may be resurred;

c. The accuracy of each Type A test shall be verified by a supplemental test which:

1) Confirms the accuracy of the test by verifying that the absolute value of the supplemental test result, L,, minus the sum of the Type A and the superimposed leak, L , is equal to or less than 0.25 L,;

2) Has a duration sufficient to establish accurately the change in leakage rate between the Type A test and the supplemental test; and

3) Requires that the rate at which gas is injected into the containment or bled from the containment during the supplemental test is between 0.75 L, and 1.25 L,. l

d. Type B and C tests shall be conducted with gas at a pressure not less than P,, 37 psig, at intervals no greater than 24 monthstexcept for tests involving:

1) Air locks and j l

2) Purge supply and exhaust isolation valves with resilient 4 material seals. l l

e. Air locks shall be tested and demonstrated OPERABLE by the require- I ments of Specification 4.6.1.3; i

f. Purge supply and exhaust isolation valves with resilient material l seals shall be tested and demonstrated OPERABLE by the requirements I of Specification 4.6.1.7.2;

g. The provisions of Specification 4.0.2 are not applicable.
