REVIEW RESPONSIBILITIES Primary - Mechanical Engineering Branch (MEB) Secondary - None I. AREAS OF REVIEW The MEB reviews information in the SAR concerning methods of analysis for seismic Category I components and supports, including both those designated as Code* Class 1, 2, 3, or CS and those not covered by the Code. Certain aspects of dynamic system analysis methods are discussed in Standard Review Plan Section 3.9.2 as well as this SRP section. Information is also reviewed concerning design transients for Code Class 1 and CS components and supports. The following specific subjects are reviewed under this SRP section: 1. Transients which are used in the design and fatigue analyses of all Code Class 1 and CS components, and supports and reactor internals. The Reactor Systems Branch confirms on request the acceptability of the listed transients and the number of cycles and events expected over the service lifetime of the plant. The Structural Engineering Branch confirms the seismic cyclic ground input loading as described in SRP Section 3.7.3. The method used to determine the seismic cyclic loading used for fatigue analysis of appropriate components and supports will be reviewed. 2. Description and verification of all computer programs which will 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 which will be used in lieu of theoretical stress analyses. 3Aerican Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Section III (hereafter "the Code").
