ent in meeting the SECY-93-087, Section II.N, expectation. IV. EVALUATION FINDINGS The reviewer verifies that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the following type to be included in the staff’s SER. The reviewer also states the bases for those conclusions. In the SER, the staff should provide a summary description of the applicant’s design-specific or plant-specific PRA and severe accident evaluations, following the topical outline provided in RG 1.206, Section C.I.19. The SER should also identify the PRA and severe accident evaluation information that the applicant docketed and the information reviewed by the NRC during audits. The results of the staff review, including staff audits, should reflect a consistent and scrutable evaluation of the applicant’s PRA and severe accident evaluations. Based on an evaluation of the acceptance criteria from Subsection II of this SRP section, with guidance given in Subsection III, the staff will generally need to make a finding in the following areas: 1. The applicant has used the PRA and severe accident evaluation to identify and assess the balance of preventive and mitigative features, including consideration of operator actions. The Commission anticipates that the plant's operation will reflect a reduction in risk compared to existing operating plants. 2. The applicant has used PRA results and insights to support other programs, as identified in Subsection I of this SRP section. 3. The PRA reasonably reflects the as-designed, as-built, and as-operated plant, and the PRA maintenance program will ensure that the PRA will continue to reflect the as- designed, as-built, and as-operated plant, consistent with its identified uses and applications. 4. The PRA is of the appropriate scope, level of detail, and technical adequacy for its identified uses and applications. 19.0-39 Draft Revision 3 –November 2014 5. Appropriate ITAAC
