on, based on the methodology that meets acceptance criterion A.3 of this SRP section. In addition, the following should be included: • A description of the basis or bases for including each RAP SSC. • Clear identification of the RAP SSCs, including text descriptions and specific SSC identification numbers when applicable, 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 17.4-10 Revision 1 –May 2014 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 nonsafety-related RAP SSCs, the application should specify the QA controls for DC design activities 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. The staff should ensure that SRP 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
