Mass Point 0.0906 0.0906 Acceptance Criteria (0.75 La): < 0.225 %/ day Allowable Leakage (1.0 La): < 0.300 %/ day Notes:

(1) All test results reported at the 95 % Upper Confidence Limit and include the leakage penalty total for all Type 11 or C penetrations not challenged during performance of the ILRT.

l- (2) Both the ist and 2nd periodic tests were performed at the front of the outage prior to any repairs l or adjustments; therefore, the As-Found test result is equal to the As-Left test result.

(3) For the 2nd periodic test, both the Total Time and Mass Point results were reported in the final test report. 'Ihe Total Time leakage calculated in accordance with the BN-TOP-1 methodology is always greater than the mass point result since its UCL is calculated at the 97.5 % confidence interval.
