ation valves, is performed by the Licensing Guidance Branch (LGB)Technical Specifications Branch (TSB) at the operating license stage of review, as part of its primary review 23 responsibility for SRP Section 16.0. G. The Electrical Engineering Branch (EELB) will review the power sources for containment isolation valve operators in each line penetrating the containment to ensure that no single fault can prevent isolation of the line as part of its primary review responsibility for SRP Sections 8.3.1 and 8.3.2. In addition, the EELB, as part of its 24 DRAFT Rev. 3 - April 1996 6.2.4-4 review responsibility for SRP Section 8.4 (proposed), reviews the capability to withstand or cope with, and recover from an SBO and coordinates with the review of containment isolation system to ensure appropriate functioning of the system for an SBO.25 H. For new plant applicants, the Probabilistic Safety Assessment Branch (SPSB) will review containment integrity issues during shutdown and low-power operations under the systematic assessment of shutdown risk as part of its primary review responsibility for SRP Section 19.1 (proposed).26 For those areas of review identified above as being reviewed as part of the primary responsibility of other branches, the acceptance criteria and methods of application are contained in the referenced SRP section of the corresponding primary branch.27 II. ACCEPTANCE CRITERIA The CSBSCSB will accept the containment isolation system design if the relevant requirements 28 of General Design Criteria l, 2, 4, 16, 54, 55, 56, and 57, Appendix K to 10 CFR Part 50, additional TMI-related requirements in 10 CFR 50.34(f)(2)(xiv) and (xv), and the station 29 30 blackout requirements of 10 CFR 50.63(a)(2), are met. The relevant requirements are as 31 follows: 1. General Design Criteria 1, 2, and 4, as they relate to systems important to safety being designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety
