AND 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 nonsafety systems. 1. The specific areas of review for piping systems and support design are divided into four subheadings: 3.12-2 Draft Revision 1 – June 2013 A. Piping Analysis Methods. The information presented in the SAR concerning the piping analysis methods for Seismic Category I, Category II, and nonsafety systems is reviewed. In addition to the guidance in this SRP section, the areas of review for seismic system analysis provided in SRP Section 3.9.2 are to be used as guidance for reviewing the seismic loading portions of the piping analysis methods. 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. 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 review for modeling, provided in SRP Section 3.9.2 are to be used as guidance for reviewing piping modeling techniques. The description and verification of all computer programs used for the analysis of Seismic Category I piping designated as Code Class 1, 2, and 3 and non-Code items are reviewed. The areas of review provided in SRP Section 3.9.1 are to be used as guidance for reviewing computer codes. The specific areas of review are: i. Computer Codes ii. Dynamic Piping Model iii.
