Content:
Also, unless there is a virtually unlimited supply of sealing liquid (such as from a suppression pool or recirculation sump), limits for liquid leakage rate should be assigned to these valves based on analysis and included in the plant technical specifications. Periodic leakage rate testing, using the sealing liquid as the test medium, is then needed to ensure that the technical specification limits are maintained. For Case No. 3, to ensure that containment integrity is restored following testing, the test, vent, and drain connections that are used to facilitate local leakage rate testing and the performance of the CILRT should be under administrative control and should be subject to periodic surveillance, to ensure their integrity and to verify the effectiveness of administrative controls. The testing requirements for BWR drywell steam bypass are discussed in SRP Section 6.2.1.1.C. Operational Programs. For COL reviews, the description of the operational program and proposed implementation milestones for the Containment Leak Rate Testing Program are reviewed in accordance with 10 CFR Part 50, Appendix J. The implementation milestones are as follows: A. Appendix J, Option A, Section III: Type A, B and C test: prior to any reactor operating period. B. Appendix J, Option B, Section III.A: Type A test: after the containment has been completed and is ready for operation. Type B & C test: prior to initial criticality Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs: 1. Compliance with GDC 52 requires that the reactor containment and associated equipment be designed so that periodic integrated leakage rate testing can be conducted at containment design pressure. 6.2.6-7 Revision 3 - March 2007 GDC 52 applies to SRP Section 6.2.6 because the review focuses on containment leakage rate testing, which includes the integrated leakage rate
