CONTAINMENT SYSTEMS SURVEILLANCE RE001REMENTS (Continued) b.
If any periodic Type A test fails to meet.75 L. the test schedule for subsequent Type A tests shall be r$ viewed and approved by the Comission. If two consecutive Type A tests fail to meet.75 L, a Type A test shall be performed at least every 18 months until two consecutive Type A tests meet.75 L, at which time the above test schedule may be resumed.
c.
The accuracy of each Type A test shall be verified by a supple-mental test which:
1.
Confirms the accuracy of the Type A test by verifying that the difference between supplemental and Type A test data is within 0.25 L,.
2.
Has a duration sufficient to establish accurately the change in leakage between the Type A and the supplemental
(
20 test.
3.
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 percent of the total measured leakage rate at Pa (54 psig).

d.
Type B and C tests shall be conducted at Pa (54 psig) at cir locks.

The combined bypass leakage rate shall be detemined to be <
0.017 L by appHeable Type B and C tests at least once per 24 months $xcept for penetrations which are not individually testable; penetrations not individually testable shall be determined to have no detectable leakage when tested with soap bubbles while the containment is pressurized to P, (54 psig) during each Type A test.
f.
Air locks shall be tested and demonstrated OPERABLE per Sur-veillance Reguirement 4.6.1.3.
