Content:
ltimate 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. Any computer program used should meet the applicable requirements of subsection II.2.C of this SRP section. 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 with elastic or elastic-plastic system analyses, the bases for these procedures are reviewed. The applicant should provide assurance that the calculated item or item support deformations and displacements do not violate the corresponding limits and assumptions on which the methods for the system analysis are based. 5. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the final safety analysis report (FSAR) meets the acceptance criteria. DCs have referred to the FSAR as the design control document (DCD). The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL action items; however, to ensure these COL action items are addressed during a COL application, they should be added to the DC FSAR. For review of a COL application, the scope of the review is dependent on whether the COL applicant references a DC, an early site permit (ESP) or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). For review of both DC and COL applications, SRP Section 14.3 should be followed for the review of ITAAC. The review of ITAAC cannot be completed until
