THEIR ASSOCIATED SUPPORTS REVIEW RESPONSIBILITIES Primary - Organization responsible for mechanical engineering reviews Secondary - None I. AREAS OF REVIEW The reviewer evaluates the information presented in the applicant’s safety analysis report (SAR) concerning the design and analyses of piping systems. The design of piping systems should include seismic Category I, Category II, and non-safety systems. Standard Review Plan (SRP) Section 3.12 is a compilation of guidance from existing Standard Review Plans, generic communications, Regulatory Guides (RG) and issues related to piping design and analyses identified in the Safety Evaluation Reports (SERs) of approved design certifications. 1. The specific areas of review for piping systems and support design are divided into four subheadings: A. Piping Analysis Methods The information presented in the SAR concerning the piping analysis methods for seismic Category I, Category II, and non-safety systems is reviewed. The areas of review for seismic system analysis provided in SRP Section 3.9.2 are to be used as guidance for reviewing piping analysis methods. 3.12-2 March 2007 Since there are numerous technical issues related to piping design and piping support other than seismic analysis and those criteria discussed in this SRP, the review also covers common industry practices and practical engineering considerations proven through extensive experience as referenced in the applicant’s SAR. The specific areas of review are: i. Experimental Stress Analysis Methods ii. Modal Response Spectrum Method iii. Response Spectra Method-Independent Support Motion Method iv. Time History Method v. Inelastic Analysis Method vi. Small Bore Piping Method vii. Nonseismic/Seismic Interaction (II/I) viii. Category I Buried Piping, Conduits, and Tunnels. B. Piping Modeling Techniques The information presented in the SAR related to criteria and procedures for the modeling of piping systems and piping supports is reviewed. The areas of
