of regulatory procedures and policies. Standard review plans are not substitutes for regulatory guides or the CommIsson's regulations and compliance with them is not required. The standard review plan sections are keyed to the Standard Format and Content of Safety AnalysIs Reports for Nuclear Power Plants. Not all sections of the Standard Format have a*corresponding review plan. Published standard review plans will be revised periodically, as appropriate, to accommodate comments and to reflect new informa- tion and experience. Comments and suggestions for Improvement will be considered and should be sent to the U.S. Nuclear Regulatory Commission. Office of Nuclear Reactor Regulation. Washington. D.C. I M5. g. The acceptability of closed piping systems inside containment as isolation barriers. 2. The protection provided for containment isolation provisions against loss of function of missiles, pipe whip, and earthquakes. 3. The environmental conditions inside and outside the containment that were considered in the design of isolation barriers. 4. The design criteria applied to isolation barriers and piping. 5. The provisions for detecting a possible need to isolate remote-manual- controlled systems, such as engineered safety features systems. 6. The design provisions for and technical specifications pertaining to operability and leakage rate testing of the isolation barriers, 7. The calculation of containment atmosphere released prior to isolation valve closure for lines that provide a direct path to the environs. CSB will coordinate other branch evaluations that interface with the overall review of the containment isolation system, as follows: The Mechanical Engineering Branch (MEB) will review the system seismic design and quality group classification as part of its primary review responsibility for SRP Sections 3.2.1 and 3.2.2, respectively. The Structural Engineering Branch (SEB) and the MEB will review the mechanical and structural design of the con- tainment
