and 11 to evaluate the functionality assurance programs for purge and vent valves and deep draft pumps. F. The staff will review the analytical procedures used alone or in conjunction with testing to demonstrate functionality by comparing the information submitted in the applicant’s program with the acceptance criteria delineated in Subsections II.1 or II.2 of this SRP section. For pumps, valves, and dynamic restraints, the references cited in Subsection II.2.E of this SRP section provide additional 3.10-19 Draft Revision 4 – August 2015 criteria for demonstrating functionality by analysis, and the reviewer will use them to supplement the staff’s review procedures. 3. Reviews of COL applications should include audits of the equipment qualification file. The staff should review the results of tests and analyses to accomplish the following: A. Ensure that the criteria in the certified design were properly implemented. B. Ensure that adequate qualification was demonstrated for all equipment and supports. C. Verify that the testing and analyses performed, or experience database used, properly defined and accounted for all applicable loads. In the advanced boiling-water reactor (ABWR) and System 80+ DC final safety evaluation reports (SERs), the staff accepted an exemption from the requirement in Appendix A to 10 CFR Part 100, “Seismic and Geologic Siting Criteria for Nuclear Power Plants,” that all safety-related SSCs be designed to remain functional and within applicable stress and deformation limits when subjected to an OBE. This exemption was based on the licensees’ alternative analyses performed for the SSE and procedural requirements to perform an inspection of the plant following an earthquake at or above one-third the SSE (see Appendix S to 10 CFR Part 50). The staff concluded in SECY 93-087, “Policy, Technical, and Licensing Issues Pertaining to Evolutionary and Advanced Light-Water Reactor (ALWR) Designs,” that the effect of eliminating the OBE
