ts associated Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” (e.g., requirements in the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPV Code), Section III, Subsection NG that may be invoked for reactor pressure vessel (RPV) internals, as described in SRP Section 3.9.5). 2. The applicant’s identification of the quality group classification for fluid systems important to safety and the system components including pressure vessels, heat exchangers, storage tanks, pumps, piping, and valves (typically presented in a table in the final safety analysis report (FSAR)). The associated quality group classification should be consistent with the applicable ASME BPV Code and code class and the applicable quality assurance criteria in Title 10 of the Code of Federal Regulations (10 CFR) Part 50, “Domestic Licensing of Production and Utilization Facilities,” Appendix B, “Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants”; ASME NQA-1; or other appropriate standards such as those identified for risk-significant mechanical systems and components. Where sufficient level of detail is not included in the table, the review may include the applicant’s presentation, on suitable system descriptions and schematics or simplified piping and instrumentation diagrams (P&IDs), if applicable, of the system quality group classifications. Other branches responsible for the review of each system description and schematics or P&IDs, if applicable, included in other sections may identify to the SRP Section 3.2.2 reviewer any discrepancies in classifications from the corresponding SRP section for that system. 3. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) reviews, the staff reviews the applicant’s proposed ITAAC associated with
