have been correctly translated into the detailed design documents used for procurement and construction of every RAP SSC. The D-RAP ITAAC provides assurance to the staff that appropriate controls were imposed during the development of design products for RAP SSCs. Subsequent activities, including system ITAAC, are predicated on the assumption that those products are correct. This ITAAC should include all RAP SSCs so that no RAP SSC is overlooked. The staff considers the scope of this ITAAC fixed when the COL is issued. Subsequent changes to the list can only occur through D-RAP activities, providing reasonable assurance that appropriate controls are applied to SSCs that are added to the scope of RAP. Such modifications may change the particular reliability assurance activities that apply to a particular SSC (e.g., a change in safety classification); in that case, the acceptance criterion would simply be met by a different D-RAP activity. 17.4-11 Draft Revision 1 – May 2013 Other staff inspections are relied upon to provide ongoing confidence that the D- RAP activities are effective (e.g., staff inspections to verify implementation of 10 CFR Part 50, Appendix B requirements and staff inspections of quality controls applied to SSCs that are not safety-related). These obviate the need for an ITAAC to confirm that the implementation controls of D-RAP are accomplished. Other ITAAC will confirm that the construction is correct and the as-built configuration is consistent with the approved design documents. An acceptable D-RAP ITAAC would include a design commitment that the design of RAP SSCs is consistent with the risk insights and key assumptions from probabilistic, deterministic, and other methods of analysis used to identify and quantify risk (e.g., SSC design, reliability, and availability). An analysis would demonstrate that the initial design of all RAP SSCs has been completed in accordance with the D-RAP. The staff considers the initial design to be complete
