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,.
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)
