Content:
nt atmosphere leak path, and may be found acceptable 6.2.6-3 Rev. 2 - July 1981 if it can be demonstrated in accordance with the requirements of Section III.C of Appendix J, that a liquid inventory is available to maintain a water seal (while assuming the single failure of any active component) during the post- accident period. Limits for liquid leakage should be assigned to these valves based on analysis and included in the plant Technical Specifications. Leak testing, to assure that containment integrity is restored following the test, vent and drain (TVD) connections that are -used to facilitate local leak testing and the performance of the containment integrated leak rate test, should be under administrative control, and should be subject to periodic sur- veillance, to assure their integrity and verify the effectiveness of adminis- trative controls. The testing requirements for BWR drywell steam bypass are discussed in SRP Section 6.2.l.l.C. III. REVIEW PROCEDURES At the CP stage, the CSB will review the preliminary design provisions that will permit containment leak testing to be done in accordance with the require- ments of Appendix J. In some instances, however, the applicant may not be able to address specific aspects of the leak testing program because of incomplete designs. Under these circumstances the CSB will review design criteria, and other commitments, that will assure compliance with the requirements of Appendix J. In addition, the CSB will review the applicant's rationale for concluding that the requirements of Appendix J will be met. At the OL stage, the CSB reviews the containment final design and verifies that the containment leak testing program meets the requirements of Appendix J. In addition, the CSB reviews the plant Technical Specifications for completeness and for conformance to Appendix J. The review of the reactor containment leakage rate test program at the OL stage specifically includes the following: 1. Containment Integrated Leakage
