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 (BPV Code), Section III 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, “Dynamic Testing and Analysis of Systems, Structures, and Components,” as well as this SRP section. Also reviewed is information on design transients for ASME BPV Code Class 1 components, component supports, reactor core support structures and reactor vessel internal components. The specific areas of review are as follow: 1. Transients used in the design and fatigue analyses of all ASME Code Class 1 components, component supports, reactor core support structures and reactor vessel internal components. Computer programs to be used in analyses of seismic Category I, ASME BPV Code and non- Code components listed in this SRP section. 3.9.1-2 Draft Revision 4 – August 2015 1. Experimental stress analyses to be used in lieu of theoretical stress analyses. 2. The elastic-plastic stress analysis methods to be performed in the design of any components. 3. The environmental conditions to which all safety-related components will be exposed over the life of the plant. 4. 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
