s due to inadvertent operation of the TBS from faults in the TBS instru- mentation and control. Rev. 2 - July 1981 USNRC STANDARD REVIEW PLAN Standard review plans are prepared for the guidance of the Office of Nuclear Reactor Regulation staff responsible for the review ot 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 plai 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 ad 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. 2OEi. In the review of the turbine bypass system the PSB will coordinate other branches' evaluations that interface with the overall review of the system as follows: The Mechanical Engineering Branch (MEB) determines that the appropriate seismic and quality group classifications have been established for system components as part of its primary review responsibility for SRP Sections 3.2.1 and 3.2.2. The Auxiliary Systems Branch (ASB) determines that TBS is in accordance with Branch Technical Positions ASB 3-1 and MEB 3-1 as related to cracks and breaks in high- and moderate-energy piping outside of containment as part of its primary review responsibility for SRP Section 3.6.1. The Reactor Systems Branch (RSB) determines that the steam bypass capacity is consistent with reactor transient analysis as part
