ments to provide reasonable assurance that RAP SSCs do not degrade to an unacceptable level of reliability, availability, or condition during plant operations.3 3. For the non-safety-related RAP SSCs, establishment of QA controls for activities during the operations phase (which include establishing appropriate corrective actions for potential design and operational errors that could degrade these SSCs) in accordance with the provisions in Part V, "Non-safety-Related SSC Quality Controls," of SRP Section 17.5. The staff will conduct the review of these QA controls under Part V of SRP Section 17.5. 4. Consideration of dominant failure modes of RAP SSCs, which are determined in accordance with the process established under the referenced DC, as it relates to maintaining the reliability and availability of RAP SSCs commensurate with their risk significance. For example, dominant failure modes could be used to facilitate the identification of specific reliability assurance activities or strategies (e.g., inservice inspection, inservice testing, surveillance testing, monitoring, and maintenance) to maintain equipment performance consistent with the risk insights and key assumptions for the RAP SSCs. One acceptable method for integrating the RAP into operational programs is by implementation of the following operational programs: (1) maintenance rule program consistent with RG 1.160, with all RAP SSCs being categorized as having HSS, (2) QA program for safety-related SSCs established through Appendix B to 10 CFR Part 50 requirements, (3) QA controls for non-safety- related RAP SSCs established in accordance with Part V of SRP Section 17.5, and (4) inservice inspection, inservice testing, surveillance testing, and maintenance programs for the RAP SSCs to maintain equipment performance consistent with risk insights and key assumptions and to address dominant failure modes.
