ained in Regulatory Guide (RG) 1.160, “Monitoring the Effectiveness of Maintenance at Nuclear Power Plants” (RG 1.160), provided that all RAP SSCs are included in the scope of maintenance rule and categorized as having high safety significance (HSS). 2. Establishment of performance and condition monitoring requirements to provide reasonable assurance that RAP SSCs do not degrade to an unacceptable level of reliability, availability, or condition during plant operations.3 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. 17.4-13 Revision 1 –May 2014 3. For the nonsafety-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, "Nonsafety-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
