ce criteria is agreed upon, additional technical justification be submitted. 2. The information pertaining to computer programs which is presented in the applicant's SAR is reviewed as follows: a. The list of programs is evaluated to determine that the applicant has adequately described each program with respect to the type of analysis that is performed and the specific components to which the program is applied. 3.9.1-7 DRAFT Rev. 3 - April 1996 b. The submitted computer solutions to the test problems required in subsection II.2 of this SRP section are reviewed and compared to with the test solutions. Satisfactory agreement of computer and test solutions, usually within a +5% error band, provides verification of the quality and adequacy of the computer programs to perform the functions for which they were designed. Any deviations that have not been justified to the satisfaction of the staff are identified and the finding is transmitted to the applicant with a request that, unless conformance with the MEBEMEB acceptance criteria is agreed upon, additional technical 30 justification be submitted. 3. If the applicant elects to use experimental stress analysis techniques in lieu of theoretical stress analyses, sufficient information must be presented in the SAR to demonstrate that the requirements of Appendix II to Reference 7 as they apply to the conditions set forth 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 Reference 7), the review covers the following points: a. The applicant must demonstrate that the stress-strain relationship for component materials that will be used in the analysis is valid. The ultimate strength values at service temperature must be justified. b. The analytical procedures to be used in the analysis are reviewed to
