1 Primary CONTAINMENT INTEGRITY ensures that the release of I

radioactive materials from the containment atmosphere will be restricted to those leakage paths and associated leak rates assumed in.the safety analyses.

limitation, will limit the EXCLUSION AREA BOUNDARY radiation doses to

Then.ovetalliconta.inment"I]eakage:ratt 110;L',Q As an added conservatism, the measured overall integrated leakage rate is further limited to less than or equal to 0.75 L during performance of the periodic test to account l

for possible degradation of the containment leakage barriers between l

leakage tests.

For specific system configurations, credit may be taken for a 30-day water seal that will be maintained to prevent containment atmosphere leakage through the penetrations to the environment.
