3/4.6 CONTAINMENT SYSTEMS BASES 3/4.6.1 PRIMARY CONTAINMENT 3/4.6.1.1 CONTAINMENT INTEGRITY Primary CONTAINMENT INTEGRITY ensures that the release of radioactive materials from the contair. ment atmosphere will be restricted to those leakage paths and associated leak rates assumed in the accident analyses.
This restric-tion, in conjunction with the leakage rate limitation, will limit the site boundary radiation cases to within the limits of 10 CFR 100 during accident conditions.
3/4.6.1.2 CONTAINMENT LEAKAGE The limitations on containment leakage rates (including those used in demonstrating a 30 day water seal) ensure that the total containment leakage volume will not exceed the value assumed in the accident analyses at the peak accident pressure, P.
As an added conservatism, the measured overall inte-grated leakage rate is further limited to less than or equal to 0.75 L or 0.75 L, as applicable, during performance of the periodic test to acc8unt for possibkedegradationofthecontainmentleakagebarriersbetweenleakagetests.
The surveillance testing for measuring leakage rates are consistent with the requirements of Appendix "J" of 10 CFR 50.
3/4.6.1.3 REACTOR BUILDING AIR LOCKS The limitations on closure and leak rate for the reactor building air locks are required to meet the restrictions on CONTAINMENT INTEGRITY and containment leak rate.
Surveillance testing of the air lock seals provide assurance that the overall air lock leakage will not become excessive due to seal damage during the intervals between air lock leakage tests.
