CONTAINMENT SYSTEMS CONTAINMENT LEAKAGE LIMITING CONDITION FOR OPERATION 3.6.1.2 Containment leakag'e rates shall be limited to:
a.
An overall integrated leakage rate of:
1.
1 L,pe(r 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> at P,, 50 psig, or 346,000 SCCM), 0.20 percent by weight of the containment air 2.

b.
A combined leakage rate of 10.60 L (207,600 SCCM), for all penetra-tions trei ' al'fes subject to Type B $nd C tests when pressurized to P,.
APPLICABILITY:
MODES 1, 2, 3 and 4.
ACTION:
With either (a) the measured overall integrated co'ntainment leakage rate or (b) with the Sea (259,500sured combined leakage fate for all penetrations an exceeding 0.75 L SCCM) or 0.75 L (46,200 SCCM), as applicable, subject to Types B and C tests exceeding 0.60 L, restore the leakage rate (s) to within the limit (s) prior to increasing the Reactor Coolant System temperature above 200*F.
