d prioritizes risk-significant SSCs based on probabilistic, deterministic, and other considerations (e.g., the plant-specific PRA). Specifically, in the final safety evaluation reports, NUREG-1462 for the System 80+ (Reference 11) and NUREG-1503 for the Advanced Boiling Water Reactor (Reference 12), and in SECY 95-132, the Commission approved the following applicable regulation for D-RAP for the DC-applicant and the COL applicant: An application for advanced reactor design certification or a combined license must contain: 1. A description of the RAP that includes the scope, purpose, and objectives of the D-RAP; 2. The process used to evaluate and prioritize the SSCs in the design, based on their degree of risk significance; 3. A list of SSCs designated as risk significant; and 4. For those SSCs designated as risk significant: (i) a process to determine dominant failure modes that considered industry experience, analytical models, and applicable requirements; and (ii) key assumptions and risk insights from probabilistic, deterministic, or other methods that considered operations, maintenance and monitoring activities. Each COL holder that references a certified design must implement the D-RAP approved by the NRC.2 1. Design Certification (DC) Application D-RAP Requirements - The D-RAP for the design certification application will include the following: a. The scope, purpose, objectives and essential elements of the D-RAP. 17.4-3 DRAFT Rev. 0 - April 1996 b. Identification and prioritization of risk-significant SSCs, including anticipated operations, maintenance, and surveillance activities. This process should be based on probabilistic or deterministic considerations, as well as other possible sources of information (e.g., standard design certification PRA, advice from an expert panel). The D-RAP should specify the following: (1) A process for identifying and prioritizing SSCs that is based on risk significance; (2) The list of SSCs designated as risk significant for
