Content:
At the CP or design certification stage, the preliminary design provisions that will permit containment leakage rate testing to be done in accordance with the requirements of Appendix J are reviewed. In some instances, however, the applicant may not be able to address specific aspects of the leakage rate testing program because of incomplete designs. Under these circumstances, the design criteria, and other commitments, that will ensure compliance with the requirements of Appendix J are reviewed. In addition, the applicant's rationale for concluding that the requirements of Appendix J will be met is reviewed. If, on the other hand, the applicant is able to address specific aspects of the leakage rate testing program, the review will be akin to the OL or COL stage review, described below, as much as practical considering the detail provided by the applicant. At the OL or COL stage, the containment final design is reviewed and it is verified that the containment leakage rate testing program meets the requirements of Appendix J. In addition, 6.2.6-9 Revision 3 - March 2007 the plant technical specifications are reviewed for completeness and for conformance to Appendix J. The review of the reactor containment leakage rate test program at the OL or COL stage specifically includes the following: 1. CILRT (Type A Test). Those systems not vented or drained should be identified and the reason for not venting or draining should be stated. Piping and instrumentation diagrams and process flow drawings are used by the reviewer to confirm that, in the vented and drained condition, the isolation valves are exposed to the test air pressure and differential pressure, i.e., the systems are vented and drained both upstream and downstream of the containment isolation valves. For Option B, guidance on venting and draining is available in Section 8.0 of NEI 94-01, Rev. 0. 2. Containment Penetration Leakage Rate Test (Type B Test). All containment penetrations should be listed in the
