ng 10 CFR 52.97(b)(1), which sets forth the comprehensive requirements for ITAAC. For design certification reviews, the scope of ITAAC is limited to the scope of the certified design as required by 10 CFR 52.47(b). Generic Piping Design Design certification applicants may not provide the complete design information for piping design before design certification because the design may be dependent upon as-built and as-pro- cured information. Instead, applicants may provide the processes and design acceptance criteria (DAC) by which the details of the design in this area would be developed, designed, and evaluated. The implementation of the processes is the responsibility of the COL applicant or licensee. The DAC are discussed further in Appendix A to SRP Section 14.3. The reviewer should use the SRP guidelines to evaluate the piping design information in Tier 1 and Tier 2, and perform a detailed audit of the piping design criteria, including sample calcula- tions. The staff should evaluate the adequacy of the structural integrity and functional capability of safety-related piping systems. The review is not limited to the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code Class 1, 2, and 3 piping and supports, but includes buried piping, instrumentation lines, the interaction of non-seismic Category I piping with seismic Category I piping, and any safety-related piping designed to industry standards other than the ASME Code. The staff's evaluation should include the analysis methods, design procedures, acceptance criteria, and related ITAAC (and DAC, if applicable) that are to be used for the completion and verification of the standard design piping design. The staff's evaluation should include both Tier 1 and DCD Tier 2 information regarding the applicable codes and standards, analysis methods to be used for completing the piping design, modeling techniques, pipe stress analyses criteria, pipe support design criteria, high-energy line
