DRYWELL BYPASS LEAKAGE LIMITING CONDITION FOR OPERATION 3.6.2.2 Drywell bypass leakage shall be less than or equal to 10% of the acceptable A/Jk design value of 1.0 ft2 APPLICABILITY: When DRYWELL INTEGRITY is required per Specification 3.6.2.1.

ACTION:

With the drywell bypass leakage ~ greater than 10% of the acceptable A/Jk design value of 1.0 fta, restore the drywell bypass leakage to within the limit prior to increasing reactor coolant system temperature above 200*F.

SURVEILLANCE REQUIREMENTS 4.6.2.2 At least once per 18 months, the drywell bypass leakage rate test _

shall be conducted at an initial differential pressure of 3.0 psid and the A//k shall be calculated from the measured leakage. One drywell airlock door shall remain open during the drywell leakage test such that each drywell door is leak tested during at least every other leakage rate test.

a. If any drywell bypass leakage test fails to meet the specified limit, the schedule for subsequent tests shall be reviewed and approved by the Commission. If two consecutive tests fail to meet the limit, a test shall be performed at least every 9 months until two consecutive l

tests meet the limit, at which time the 18 month test schedule may be resumed.

([b. The provisions of Specification 4.0.2 are not applicable.}h gg7--
