ese 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 Foriat and Content of Safety Analysis Reports f or 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 Commlssion, Office of Nuclear Reactor Regulation. Washington. D.C. the need for the reactor protection system and operator action to secure and maintain the reactor in a safe condition. The analytical methods are reviewed by RSB to ascertain whether the mathematical modeling and computer codes have been previously reviewed and accepted by the staff. If a referenced analytical method has not been previously reviewed, the reviewer initiates a generic evaluation of the new analytical model. In addition, the values of all the parameters used in the new analytical model, including the initial conditions of the core and system, are reviewed. The predicted results of the transients are reviewed to assure that the conse- quences meet the acceptance criteria given in subsection II, below. Further, the results of the transients are reviewed to ascertain that the values of pertinent system parameters are within ranges expected for the type and class of reactor under review. In addition, the RSB will coordinate other branches' evaluations that interface with the overall review of the system as follows: The Instrument and Control Branch (ICSB) reviews the instrumentation and controls aspects of the sequence
