ts documents that the staff could use as reference or background material during the review process. The bibliography lists documents by category, covering desirable PRA attributes, review of the PRA, uncertainty and sensitivity analyses, and use of the PRA in risk ranking. It also provides a bibliography for aspects of PRA modeling (e.g., initiating events, CCF modeling, human performance modeling). As expressed in the review interfaces portion of Subsection I of this SRP section, other technical branches are expected to use the applicant’s PRA results and insights to inform their review based on risk significance. RG 1.206 indicates the expected scope and level of detail of a PRA used to support a DC or COL application. Exceptions to this expected scope and level of detail may be acceptable if adequately justified by the applicant. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the FSAR meet the acceptance criteria. DCs have referred to the FSAR as the DCD. The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL action items; however, to ensure these COL action items are addressed during a COL application, they should be added to the DC FSAR. For review of a COL application, the scope of the review is dependent on whether the COL applicant references a DC, an early site permit or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). Specific Review Guidance The staff’s review focuses on the methods, results and insights of the design-specific or plant-specific PRA and severe accident evaluations. Design-Specific PRA (Specific Areas of Review) 1. The staff reviews the process used by the applicant to develop its design-specific or plant-specific PRA, including supporting or associated
