Primary - Reactor Systems Branch (RSB) Secondary - None I. AREAS OF REVIEW A number of transients which are expected to occur with moderate frequency, and which involve an unplanned increase in heat removal by the secondary system, are covered by this SRP section. Excessive heat removal, i.e., a heat removal rate in excess of the heat generation rate in the core, causes a decrease in moderator temperature which increases core reactivity and can lead to a power level increase and a decrease in shutdown margin. The power level increase will lead to a reactor trip. Any unplanned power level increase may result in fuel damage or excessive reactor system pressure. Each of the transients covered by this SRP section should be discussed in individual sections of the safety analysis report (SAR), as required by the Standard Format (Ref. 1). The transients to be evaluated include: 1. Pressurized Water Reactors (PWRs) and Boiling Water Reactors (BWRs) a. Feedwater system malfunctions that result in a decrease in feedwater temperature. b. Feedwater system malfunctions that result in an increase in feedwater flow. c. Steam pressure regulator malfunctions or failures that result in increased steam flow. Rev. 1 - 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 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 end 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
