mployed by the applicant to demonstrate functionality, either in conjunction with testing or by themselves, by comparing information submitted in the applicant’s program with the acceptance criteria delineated in this SRP section. The references cited in this SRP section provide additional guidance for demonstrating functionality by analysis and supplement the staff’s review procedures. E. The staff will provide assistance for NRC inspections of the functional design and qualification of pumps, valves, and dynamic restraints as necessary. During those inspections, the staff should review the results of tests and analyses to accomplish the following: i. Ensure that the criteria in the certified design were properly implemented ii. Ensure that adequate design was demonstrated for pumps, valves, and dynamic restraints important to safety iii. Verify that the testing and analyses that were performed properly defined and accounted for all applicable loads. F. SRP Sections 3.9.3 and 3.10 provide additional review guidance for safety and relief valves and dynamic restraints. 3.9.6-36 Revision 4 – March 2017 F. The reviewer should give particular attention to flow-induced loading in functional design and qualification to account for degraded flow conditions such as those that might be encountered because of the presence of debris, impurities, and contaminants in the fluid system (e.g., containment sump pump recirculating water with debris). SRP Section 6.2.2 provides additional review guidance for addressing post-LOCA generated debris. G. For passive new reactors, the staff will review the COL applicant’s description of the functional design and qualification for pumps, valves, and dynamic restraints within the scope of the RTNSS program for conformance with the criteria stated in Subsection II.1. H. The staff will review the applicant’s provisions to address potential adverse effects of flow induced vibration on pumps, valves, and dynamic restraints as described
