REVIEW RESPONSIBILITIES Primary - Organization responsible for mechanical engineering reviews Secondary - None I. AREAS OF REVIEW This Standard Review Plan (SRP) section addresses information in the safety analysis report (SAR) on methods of analysis for seismic Category I components and supports, including both those designated as American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Section III (hereafter "the Code") Class 1, 2, 3, or core support and those not covered by the Code. Certain aspects of dynamic system analysis methods are addressed in SRP Section 3.9.2 as well as this SRP section. Also reviewed is information on design transients for Code Class 1 and core support components and supports. The specific areas of review are as follow: 1. Transients used in the design and fatigue analyses of all Code Class 1 and core support components, supports, and reactor internals. 3.9.1-2 Revision 3 - March 2007 2. Description and verification of all computer programs to be used in analyses of seismic Category I Code and non-Code items listed in this SRP section. 3. Description of any experimental stress analysis programs to be used in lieu of theoretical stress analyses. 4. Description of the analysis methods to be used if the applicant elects to use elastic-plastic stress analysis methods in the design of any components. 5. The environmental conditions to which all safety-related components will be exposed over the life of the plant. 6. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) reviews, the staff reviews the applicant's proposed ITAAC associated with the structures, systems, and components (SSCs) related to this SRP section in accordance with SRP Section 14.3, "Inspections, Tests, Analyses, and Acceptance Criteria." The staff recognizes that the review of ITAAC cannot be completed until after the rest of this portion of the application has been reviewed against
