CONTAINMENT SYSTEMS CONTAINMENT LEAKAGE LIMITING CONDITION FOR OPERATION 3.6.1.2 . Containment leakage rates shall be limited to:
- a. An overall integrated leakage rate of less than or equal to La ,0.1 percent by weight of the containment air per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, at the calculated peak containment pressure P3 ,
greater than or equal to 44.1 psig.
- b. A combined leakage rate of less than or equal to 0.60 La for all penetrations and valves subject to Type B and C tests, when pressurized to Pa, greater than or equal to 44.1 psig.
APPLICABillT_Ya MODES 1,2,3, and 4.
ACTION:
With either (a) the measured overall integrated containment leakage rate exceeding 0.75 La or (b) with the measured combined leakage rate for all penetrations and valves subject to Type B and C tests exceeding 0.60 La, restore the overall integrated leakage rate to less than 0.75 La and the combined leakage rate for all penetrations subject to Type B and C tests to less than or equal to 0.60 L aprior to increasing the Reactor Coolant System temperature above 200 F.
SURVEILLANCE REQUIREMENTS 4.6.1.2 The containment and containment penetrations shall be tested by performing leakage rate testing as required by 10 CFR 50, Appendix J Option B, as modified by approved exemptions, and in accordance with the guidelines contained in Regulatory Guide 1.163, dated September 1995.
