REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of containment integrity. Secondary - None I. AREAS OF REVIEW The description of the reactor containment leakage rate testing program is reviewed for conformance to 10 CFR Part 50, Appendix J, and General Design Criteria 52, 53, and 54. Appendix J includes two options, A and B, either of which can be chosen by an applicant or licensee for meeting the requirements of the appendix. Option A is "Prescriptive Requirements" and Option B is "Performance-Based Requirements." In accordance with Option B, section V., an applicant or licensee may chose to comply with all of Option A, all of Option B, or one of the options for containment integrated leakage rate tests (CILRTs) and the other option for local leakage rate tests (LLRTs). If a mixed approach is used, experience indicates that it will likely be Option B for CILRTs and Option A for LLRTs, due to the much longer CILRT interval available under Option B. Further, the staff believes that applicants for new plants will choose Option B for all tests, due to its test interval advantages. Regardless of the choice made, a plant's Technical Specifications will indicate the choice, and a subsequent change in choice would be implemented through a Technical Specifications change. Despite the differences between Option A and Option B, there are many similarities and the review guidance below will apply to either option, unless otherwise stated. 6.2.6-2 Revision 3 - March 2007 The specific areas of review are as follows: 1. CILRTs (Type A tests as defined by Appendix J), including pretest requirements, general test methods, acceptance criteria for preoperational and periodic leakage rate tests, provisions for additional testing in the event of failure to meet acceptance criteria, and scheduling of tests. 2. Containment penetration leakage rate tests (Type B tests as defined by Appendix J), including identification of containment penetrations, general test
