ent 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 determine the validity of the analysis. If a computer program is used, the applicable requirements of subsection II.2 above shall be met. c. If elastic system analysis is used, its application may require detailed review and justification if applied to the analysis of systems which contain active components with close tolerances, or systems in which the sequence of load application could significantly affect the actual stress distribution. d. If elastic, elastic-plastic or limit analysis methods are used for components in conjunction with elastic or elastic-plastic system analyses, the basis upon which these procedures are used are reviewed. The applicant shall provide assurance that the calculated item or item support deformations and displacements do not violate the corresponding limits and assumptions on which the methods used for the system analysis are based. 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 31 justification be submitted. DRAFT Rev. 3 - April 1996 3.9.1-8 For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface
