Rev. 1 - July 1981 USNRC STANDARD REVIEW PLAN Standard review plans are prepared for the guidance of the Qifice of Nuclear Reactor Regulation staff responsible for the review of applications to construct and operate nuclear power plants. These documents are made available to the public 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. 2355 2. Design and Installation of. Pressure Relief Devices The design and installation criteria applicable to the mounting of pressure relief devices (safety valves and relief valves) for the overpressure protec-. tion of Code Class 1, 2, and 3 components are reviewed. The review includes evaluation of the applicable loading combinations and stress criteria. The design review extends to consideration of the means provided to accommo- date the rapidly applied reaction force when a safety valve or relief valve opens, and the transient fluid-induced loads applied to the piping downstream of a safety or relief valve in a closed discharge piping system. The dynamic structural response due to BWR safety relief valve discharge into the suppres- sion pool is also considered. The design of safety and relief valve systems is reviewed with respect to
