e applicant should justify them. For Code Class 1 and core support components and supports, the reviewer verifies whether for each transient loading condition or combination an acceptable Code service limit is specified (i.e., Design, Level A, Level B, Level C, or Level D as specified in ASME Code, Section III, Division 1). 2. The information on computer programs presented in the applicant's SAR is reviewed as follows: A. The list of programs is evaluated to determine whether the applicant adequately describes each program with respect to the type of analysis performed and the specific components to which the program is applied. B. The submitted computer test problem solutions recommended in subsection II.2.C of this SRP section are reviewed and compared to the test solutions. Satisfactory agreement of computer and test solutions, usually within a +5 percent error band, verifies the quality and adequacy of the computer programs for the functions for which they were designed. 3. If the applicant elects to use experimental stress analysis techniques in lieu of theoretical stress analyses, sufficient information should be presented in the SAR to demonstrate that the requirements of Appendix II to ASME Code, Section III, Division 1, applicable to the conditions in the "Design Specifications" have been met. 4. If the applicant employs an elastic or an elastic-plastic method of analysis to evaluate the design of safety-related Code or non-Code items for which Service Level D limits have been specified (NB-3225 and Appendix F to ASME Code, Section III, Division 1) the review considers the following points: 3.9.1-8 Revision 3 - March 2007 A. The applicant should demonstrate that the stress-strain relationship for component materials to be used in the analysis is valid. The ultimate strength values at service temperature should be justified. B. The analytical procedures to be used in the analysis are reviewed to determine the validity of the analysis.
