erformance consistent with risk insights and key assumptions and to address dominant failure modes. B.4 ITAAC for Design Reliability Assurance Program 3 The reliability performance monitoring does not need to statistically verify the numerical values used in the PRA. However, it should provide a feedback mechanism for periodically evaluating equipment reliability and risk significance based on actual equipment, train, or system performance and other operational history. 17.4-14 Draft Revision 1 – May 2013 In accordance with SRP Section 14.3, “Inspections, Tests, Analyses, and Acceptance Criteria,” for a COL application referencing a DC, the staff should confirm that the application specifies the D-RAP ITAAC as approved in the DC (see Section A.8 of this SRP section). Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs. The RAP is implemented in accordance with the Commission policy described in SECY-95-132, Item E. The requirement to provide a RAP is codified by incorporation within the design specific rulemaking for an applicant for DC. Meeting this requirement provides assurance that (1) the plant is designed, constructed, and operated in a manner that is consistent with the risk insights and key assumptions from the probabilistic, deterministic, and other methods of analysis used to identify and quantify risk, (2) the RAP SSCs do not degrade to an unacceptable level of reliability, availability, or condition during plant operations, (3) the frequency of transients that challenge these SSCs is minimized, and (4) these SSCs will function reliably when challenged. SECY-95-132 describes the details of RAP, such as the scope and purposes of RAP, the different stages of RAP, and the RAP information to be included in an application for new reactor and provides guidance for developing an effective RAP.
