uires that these postulated reactivity accidents include consideration of rod ejection (unless prevented by positive means), rod dropout, steam line rupture, changes in reactor coolant temperature and pressure, and cold water addition. Related Guidance • NUREG-0800, “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition” (SRP), (Ref. 3) provides guidance to the NRC staff for review of safety analysis reports submitted as part of license applications for nuclear power plants. o SRP Section 15.4.8 provides guidance to the NRC staff for reviewing PWR CRE accidents. o SRP Section 15.4.9 provides guidance to the NRC staff for reviewing BWR CRD accidents. o SRP Section 4.2 provides guidance to the NRC staff for reviewing reactor fuel designs. o SRP Section 4.2, Appendix B provides guidance to the NRC staff in reviewing both PWR CRE and BWR CRD accidents. • RG 1.183, “Alternative Radiological Source Terms for Evaluating Design Basis Accidents at Nuclear Power Reactors,” (Ref. 4) provides guidance for calculating radiological consequences for design basis accidents. • RG 1.195, “Methods and Assumptions for Evaluating Radiological Consequences of Design Basis Accidents at Light-Water Nuclear Power Reactors,” (Ref. 5) provides guidance for calculating radiological consequences for design-basis accidents. Purpose of Regulatory Guides The NRC issues RGs to describe to the licensees and public methods that the staff considers acceptable for use in implementing specific parts of the agency’s regulations, to explain techniques that the staff uses in evaluating specific problems or postulated accidents, and to provide guidance to applicants. Regulatory guides are not substitutes for regulations, and compliance with them is not required. Methods and solutions that differ from those set forth in RGs will be deemed acceptable if they provide a basis for the findings required for the issuance or continuance of a permit
