t, especially when operating under expanded operating domains. 10. The reviewer will ensure that the actual component and actuation setpoint testing supports the technical specification values used in the analyses. The reviewer will evaluate plant testing data to ensure that component performance supports the plant- specific technical specification values used in the analyses. For example, the safety/relief valve (SRV) upper lift setpoint tolerance may drift, which might affect the ATWS peak pressure. 11. The reviewer will ensure that if the technical specifications allow for equipment out of service, the ATWS analysis assumes the most conservative configuration. For example, if the technical specifications allow SRVs out of service, then the ATWS analysis should include this configuration irrespective of the basis for the technical specification section. 12. The reviewer will evaluate the need for staff confirmatory calculations if the design changes deviate significantly from established practice. 13. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the final safety analysis report (FSAR) meets the acceptance criteria. DCs have referred to the FSAR as the design control document (DCD). The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL action items; however, to ensure these COL action items are addressed during a COL application, they should be added to the DC FSAR. For review of a COL application, the scope of the review is dependent on whether the COL applicant references a DC, an early site permit (ESP) or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). 15.8-12 Revision 2 - March 2007 IV. EVALUATION FINDINGS The reviewer verifies that the applicant has provided sufficient
