c as part of the Commission's policy to Inform the nuclear Industry and the general public of regulatory procedures and policies. Standard review plans are not substitutes for regulatory guides or the Commission'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. 2055. The CSB review specifically covers the following analyses and aspects of com- bustible gas control system designs: 1. An analysis of combustible gas (i.e., hydrogen and oxygen) production and accumulation within the containment following a loss-of-coolant accident. 2. An analysis of the functional capability of the systems provided to mix the combustible gas within the containment. 3. An analysis of the functional capability of the systems provided to reduce combustible gas concentrations within the containment. 4. Analyses of the capability of systems or system components to withstand dynamic effects, such as transient differential pressures that would occur early in the blowdown phase of a loss-of-coolant accident. 5. Analyses of the consequences of single active component malfunctions. 6. The quality classification of each system. 7. The seismic design classification of each system. 8. The results of qualification tests performed on system components to demonstrate functional capability. 9. The design provisions and proposed program (including technical specifica- tions at the operating license stage of review) for periodic inservice inspection, operability testing and
