The adequacy of the qualification and inservice testing program for pumps and valves is determined in accordance with SRP Section 3.9.6. 4. The seismic qualification of equipment is assessed in accordance with SRP Section 3.10. 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 and 5.2.1.2. 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. SRP Section 14.3 provides generic guidance for ITAAC review, while SRP Section 14.3.3 provides guidance for ITAAC review for pressure-retaining components. In addition, the staff will coordinate evaluations, inside and outside the branch as needed, that interface with the overall review of system safety and quality group classification addressed in those sections as follows: The staff reviewer should identify discrepancies in system and component safety and quality group classifications, application of the quality assurance program, and codes and standards applicability in accordance with criteria and methods contained in the SRP sections corresponding to the review of the particular systems.
