zational and administrative structure needed to implement an effective D-RAP. DRAFT Rev. 0 - April 1996 17.4-12 c. A staff review verified the acceptability of the plant-specific PRA required under 10 CFR 52.47(a)(1)(v) and the process used to evaluate, identify, and prioritize the risk significance and relative importance to safety of specific SSCs. d. A staff review verified the acceptability of the list of risk significant SSCs that would be subject to D-RAP requirements. e. A staff review verified the acceptability of the process used to identify the dominant failure modes of risk-significant SSCs as guided by the PRA and as supplemented by deterministic evaluation and other sources. f. A staff review verified the acceptability of anticipated operations, maintenance, and monitoring activities for risk-significant SSCs. 2. For a Combined License (COL) SER that References a Standard Design Certification: The SAR describes the design reliability assurance program (D-RAP) for the design phase of a COL application. The D-RAP is implemented during the detailed design stage and while specific equipment is being procured, fabricated, constructed and preoperationally tested, to ensure that the reliability assumptions of the PRA will be considered throughout the life of the plant. The applicant for the COL has developed and implemented a process that includes such objectives as monitoring equipment performance and evaluating equipment reliability to provide reasonable assurance that the plant is operated and maintained commensurate with PRA assumptions, thereby ensuring that overall plant safety is not knowingly degraded and remains within acceptable limits. Based on the review of the D-RAP described in the COL application, the staff concludes that the D-RAP meets the requirements of Appendix to 10 CFR Part 52 [enter designated appendix for the certified design] for the design phase of the RAP and is therefore acceptable. This conclusion is based on the following: a. A
