. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff’s plans for using this SRP section. This SRP section will be used by the staff when performing safety evaluations of transient and accident analysis methods used in safety analysis for licenses under 10 CFR Parts 50 and 52. Except in those cases in which the applicant proposes an acceptable alternative method for complying with specified portions of the Commissions’s regulations, the method described herein will be used by the staff in its evaluation of conformance with Commission regulations. The provisions of this SRP section apply to reviews of transient and accident analysis methods submitted by licensees or vendors six months or more after the date of issuance of this SRP section. VI. DEFINITIONS All definitions are in the context of the objectives of this SRP section and may not be generic to other uses. Acceptance Review An initial review of a submittal performed to ensure that sufficient information is included for the review to conduct the review. Accidents In this SRP section, accidents and transients refer to events that are defined in NUREG-0800 (Ref. 1) to be analyzed to meet the requirements of the General Design Criteria (GDC), except for the fuel assembly misloading event and all radiological consequence analyses. Codes Calculational procedures that compose an evaluation model. Code Options User controlled options that control which procedures, models, correlations, etc., the code uses when performing calculations. Code Tuning The adjustment of parameters or options included in the code to achieve a predetermined result of code run. Compensating A set of errors that, combined, mask the effect of the individual errors. Errors Correlation The change in one parameter as a result of a change in another Effort parameter. 15.0.2-18 Initial Issuance - December 2005 Closure Equations and correlations required to close the field equations
