Content:
of 10 CFR Part 50, Appendix A, GDC 15 provides assurance that the piping systems will remain functional under all postulated design condition and ensures that RCPB components are capable of performing its intended safety function. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. The piping systems, piping components and their associated supports connected to components, must provide adequate margins of safety to maintain the functionality of components under all combinations of loadings. A. Piping Analysis Methods i. Experimental Stress Analysis methods Review the procedures, details of the method and the scope and extent of experimental stress analysis. Review the validity of the design if the method is used in lieu of analytical methods for Seismic Category I, ASME Code and non-Code piping system designs. The experimental stress analysis method should comply with ASME Code, Section III, Division 1, Appendix II. 3.12-17 Draft Revision 1 - June 2013 ii. Modal Response Spectra Method Follow the review procedures provided in SRP Section *3.9.2, Subsection III.2. iii. Response Spectra Method-Independent Support Motion Method ** Review the applicable criteria for independent support motion method of analysis (i.e., response spectra) for all Category I piping systems and supports to ensure that the criteria used for the analysis is consistent with the acceptance criteria given in Section 2, “Staff Recommendations on Response Combinations,” of NUREG-1061, Volume 4. iv. Time History Method Follow the review procedures provided in SRP Section 3.9.2, Subsection III.2. v.
