Content:
to allow the isolation barriers to be individually leak tested. This information should be tabulated in the safety analysis report to facilitate the CSB review. The CSB determines from the descriptive information in the SAR that provisions have been made in the design of the containment isolation system to allow perio- dic operability testing of the power-operated isolation valves and the containment isolation system. At the operating license stage of review, the CSB determines that the content and intent of proposed technical specifications pertaining to operability and leak testing of containment isolation equipment is in agree- ment with requirements developed by the staff. The CSB verifies that the design of the control system for automatic contain- ment isolation valves is such that resetting the isolation signal will not result in the automatic reopening of containment isolation valves, and that ganged reopening of isolation valves is not possible. IV. EVALUATION FINDINGS The information provided and the CSB review should support concluding state- ments similar to the following, to be included in the staff's safety evaluation report: The staff concludes that the containment functional design is accept- able and meets the requirements of General Design Criteria 1, 2, 4, 16, 54, 55, 56, and 57 and Appendix K to 10 CFR Part 50. The con- clusion is based on the following: [The reviewer should discuss each item of the regulations or related set of regulations as indicated.] 1. The applicant has met the requirements of (cite regulation) with respect to (state limits of review in relation to regulation) 6.2.4-10 Rev. 2 - July 1981 by (for each item that is applicable to the review state how it was met and why acceptable with respect to the regulation being discussed): a. meeting the regulatory positions in HUREG Regulatory Guide(s) _; and/or b. providing and meeting an alternative method to regulatory positions in Regulatory Guide ___, that the staff has reviewed and
