CONTAINMENT SYSTEMS SURVEILLANCE REQUIREMENTS (Continued)

b. If any periodic Type A test fails to meet 0.75 La, 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 La, a Type A test shall be performed at least every 18 months until two consecutive Type A tests meet 0.75 La, at which time the above test schedule may be resumed.

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

1. Con)irms the accuracy of the test by verifying that the differ-ence between the supplemental test data and the Type A test data is within 0.25 La. The formula to be used is: [Lo + Lam

- 0.25 La] 1 Lc 1 [Lo + Lam + 0.25 La] where Lc = supplemental test results; Lo = superimposed leakage; Lam = measured Type A leakage.

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

3. Requires the quantity of gas, injected into the . primary containment or bled from the primary containment during the supplemental test, to be netween 0.75 La and 1.25 La.

d. Type B and C tests shall be conducted with qas at Pa, 7.6 psig*, at intervals no greater than 24 months * *except for tests involving: l

1. Air locks, .

2. Main steam positive leakage control system (MS-PLCS) valves and PVLCS valves,

3. Penetrations using continuous leakage monitoring systems,

4. Primary containment isolation valves in hydrostatically tested lines per Table 3.6.4-1 which penetrate the primary containment, and

5. Purgs supply and exhaust isolation valves with resilient material seals.

e. Air locks shall be tested and demonstrated OPERA 0LE per Surveillance Requirement 4.6.1.4.

I

f. Total sealing air leakage into the primary containment, at a test  !

pressure of 11.5 psid for MS-PLCS valves and 33 psid for penetration l 1eakage control system sealed valves, shall be determined by test at  !

least once per 18 months."*This leakage may be excluded when determin-  !

l ing the combined leakage rate, 0.6 La. '
