ontainment isolation valves, is performed by the Licensing Guidance Branch (LGB), as part of its primary review responsibility for SRP Section 16.0. For those areas of review identified above as being reviewed as part of the primary review responsibility of other branches, the acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP section of the corresponding primary branch. 6.2.4-2 Rev. 2 - July 1981 II. ACCEPTANCE CRITERIA The CSB will accept the containment isolation system design if the relevant requirements of General Design Criteria 1, 2, 4, 16, 54, 55, 56, and 57 and Appendix K to 10 CFR Part 50 are met. The relevant requirements are as 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 function to be performed; systems being designed to withstand the effects of natural phenomena (e.g., earthquakes) without loss of capability to perform their safety functions; and systems being designed to accommodate postulated environmental conditions and protected against dynamic effects (e.g., missiles, pipe whip, and jet impingement), respectively. 2. General Design Criteriod 16 as it relates to a system, in concert with the reactor containment, being provided to establish an essentially leak tight barrier against the uncontrolled release of radioactivity to the environment. 3. General Design Criterion 54, as it relates to piping systems penetrating the containment being provided with leak detection, isolation, and contain- ment capabilities having redundant and reliable performance capabilities, and as it relates to design provision incorporated to permit periodic oper- ability testing of the containment isolation system, and leak rate testing of isolation valves. 4. General Design Criteria 55 and 56 as it relates to lines that penetrate the primary
