licable, to communicate the RAP SSCs effectively and accurately to the organizations that implement the D-RAP. • Clear identification of the boundaries of the RAP SSCs (e.g., electrical, mechanical, and instrumentation and control boundaries) to provide a common basis for understanding the RAP SSCs (this is important because RAP SSCs are subject to QA controls). It would be acceptable for the application to cite the specific documents where these SSC boundaries are defined (e.g., the section of the application that meets the provisions of SRP Section 3.2.2, “System Quality Group Classification,” may describe these boundaries for some RAP SSCs). A.6 Process for Determining Dominant Failure Modes The application should propose a process for determining dominant failure modes of RAP SSCs. This process should incorporate industry experience, analytical models, and applicable requirements (e.g., operating experience, PRA importance analyses, root cause analyses, failure modes and effects analyses). A.7 Quality Assurance Associated with Design Activities For non-safety-related RAP SSCs, the application should specify the QA controls for DC design activities 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. The staff should ensure that Section 17.4 of the application cites the specific sections or chapters of the application where these QA controls are described. A.8 ITAAC for Design Reliability Assurance Program The application should specify an ITAAC for the D-RAP to ensure that appropriate controls are applied to the RAP SSCs early in the COL design phase. This ITAAC ensures that the design bases and other requirements 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
