NUREG-0800 U.S. NUCLEAR REGULATORY COMMISSION January 2003 STANDARD REVIEW PLAN Office of Nuclear Reactor Regulation Contact: M.G. Kowal (301)415-1663 J.L. Staudenmeier (301)415-7002 DRAFT STANDARD REVIEW PLAN SECTION 15.0.2 REVIEW OF TRANSIENT AND ACCIDENT ANALYSIS METHODS REVIEW RESPONSIBILITIES Primary - Lead Branch for Accident or Transient Secondary - Other Branches with Responsibility for Accident or Transient I. AREAS OF REVIEW In order to establish a licensing basis, licensees must analyze transients and accidents per the requirements of 10 CFR 50.34, 10 CFR 50.46, and where applicable, per NUREG-0737, ”Clarification of TMI Action Plan Requirements.” These accidents and transients are described in the Standard Review Plan (SRP) (NUREG-0800) [Ref. 1]. This section of the SRP describes the review process and acceptance criteria for analytical models and computer codes used by licensees to analyze accident and transient behavior. The purpose of the review is to verify that the evaluation model is adequate to simulate the accident under consideration. This includes methods to estimate the uncertainty in the calculation, as in the case of a best estimate loss of coolant accident (LOCA); or to ensure that the results of the analysis are demonstrably conservative, as in the case of a LOCA in Appendix K to 10 CFR Part 50. The guidance in this section should be applicable to most of the transients and accidents described in the SRP. Appendices that provide specific information for specific classes of accidents and transients will be developed in the future. Guidance to the industry is proposed in 2 Draft Regulatory Guide DG-1120, “Transient and Accident Analysis Methods” [Ref. 2].
