’s regulations, and compliance with it is not required. However, an applicant is required to identify differences between the design features, analytical techniques, and procedural measures proposed for its facility and the SRP acceptance criteria and evaluate how the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations. 3.12-7 March 2007 A. Piping Analysis Methods i. Experimental Stress Analysis Methods If experimental stress analysis methods are used in lieu of analytical methods for Seismic Category I ASME Code and non-Code piping system designs, the applicant should provide sufficient information to show the validity of the design. It is recommended, prior to use of the experimental stress analysis methods, that details of the method as well as the scope and extent of its application, be submitted for approval. The experimental stress analysis methods provided in Appendix II to ASME Code, Section III, Division 1 are applicable. ii. Modal Response Spectrum Method The SRP acceptance criteria provided in SRP Section 3.9.2, Subsection II.2 are applicable. iii. Response Spectra Method- Independent Support Motion Method This method may be used in lieu of the response spectra method when there is more than one supporting structure. The acceptance criteria provided in NUREG-1061, Volume 4 are applicable. iv. Time History Method The SRP acceptance criteria provided in SRP Section 3.7.2, Subsection II.6 are applicable. v. Inelastic Analysis Method If inelastic analysis methods are used for the piping design, the applicant will provide sufficient information to show the validity of the analysis. It is recommended, prior to use of the inelastic analysis method that details of the method, as well as the scope and extent of its application and acceptance criteria, be submitted for approval. The inelastic analysis methods provided in SRP Section 3.9.1, Subsection II.4 are applicable. vi. Small Bore Piping
