, as part of design certification rulemaking. The design phase of the RAP is verified using the ITAAC process. 2. The RAP provides reasonable assurance that (1) a reactor is designed, constructed, and operated in a manner that is consistent with the assumptions and risk insights for risk-significant procurement specifications SSCs, (2) SSCs do not degrade to an unacceptable level during plant operations, (3) the frequency of transients that challenge advanced reactor SSCs are minimized, and (4) SSCs function reliably when challenged. The RAP also provides (1) a mechanism for establishing baseline reliability values for SSCs identified by the risk determination methods used to implement the Maintenance Rule (10 CFR 50.65) that is consistent with PRA reliability and availability design-basis assumptions, (2) a mechanism for establishing baseline reliability values for SSCs consistent with the defense-in-depth functions to minimize challenges to the safety- related systems, and (3) design and operational information to be used by a COL applicant/holder for ongoing plant reliability assurance activities. III. REVIEW PROCEDURES The reviewer will select provisions from the above acceptance criteria as may be appropriate for a particular case. For deviations from these specific acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives or exceptions to the SRP criteria provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. 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
