epetition of similar information (e.g., tables or lists of components, system drawings). 2. The systems and components important to safety that are designated as Quality Groups A, B, C, or D items are reviewed to determine if they will be constructed in accordance with the regulatory guides, industry codes, and standards that are referenced in SRP Sections 3.2.1, 3.9.1, “Special Topics for Mechanical Components,” through 3.9.3, “ASME Code Class 1, 2, and 3 Components, and Component Supports, and Core Support Structures,” 3.9.5, “Reactor Pressure Vessel Internals,” and 3.11, “Environmental Qualification of Mechanical and Electrical Equipment.” 3. The adequacy of the qualification and inservice testing program for pumps and valves is determined in accordance with SRP Section 3.9.6, “Functional Design, Qualification, and Inservice Testing Programs for Pumps, Valves, and Dynamic Restraints.” 4. The seismic qualification of equipment is assessed in accordance with SRP Section 3.10, “Seismic and Dynamic Qualification of Mechanical and Electrical Equipment.” 5. The quality group classification of systems and components comprising the reactor coolant pressure boundary (RCPB) is reviewed and the adequacy of proposed RCPB construction codes and code cases is determined, as part of the staff’s primary review responsibility for SRP Sections 5.2.1.1, “Compliance with the Codes and Standards Rule, 10 CFR 50.55a,” and 5.2.1.2, “Applicable Code Cases.” 6. The identification and evaluation of nonsafety-related risk-significant SSCs is reviewed in accordance with the guidance in SRP Chapters 17 and 19 and DC/COL-ISG-018 concerning quality assurance (QA) and reliability assurance. 7. The proposed ITAAC for quality group classifications is reviewed in accordance with SRP Sections 14.3 and 14.3.3, “Piping Systems and Components - Inspections, Tests, Analyses, and Acceptance Criteria.” SRP Section 14.3 provides generic guidance for ITAAC review,
