be conducted at 40 + 10 month intervals during shutdown at P 49 psig, or P, 25 psig, during each 10 year service period.,,The g
third test of each set shall be conducted during the shutdown for the 10 year plant inservice inspection.-

the test schedule for subsequent Type A tests shall be reviewed an approved by the Commission.
If two consecutive Type A tests fall to meet (0.7 L qr

The accuracy of each Type A test shall be_ verified by a supplemental c.
test which _

Confirms the accuracy of the test by verifying that the difference between the supplemental data and the Type A test data is within 0.25 L, or 0.25 L.

Has duration sufficient to establish accurately the change in leakage rate between the Type A test-and the supplemental test.

Requires,the quantity of gas injected into the_ containment or bled from the containment during the supplemental _ test to be equivalent to at least 25 percene of the total measured leakage rate-at-P,,-49 psig, or P, 25 psig.
