ant must address COL action items (referred to as COL license information in certain DCs) included in the referenced DC. Additionally, a COL applicant must address requirements and restrictions (e.g., interface requirements and site parameters) included in the referenced DC. Review Interfaces The organization responsible for structural engineering supports the review of the PRA and severe accident evaluation in two main areas: the applicant’s evaluation of seismic contributors (specifically the seismic hazard analysis and estimation of seismic capacities (acceleration at which there is high confidence in low probability of failure) (HCLPF value) and the applicant’s analysis of containment performance. This organization provides written input to the SER. Acceptance criteria for these sections are outlined below. Other organizations that use the PRA and severe accident evaluation results and insights in their programs, processes, and reviews (e.g., human factors, emergency preparedness, security, inspection, technical specifications (TS), regulatory treatment of non-safety systems (RTNSS), maintenance rule implementation) may need to interface with the PRA staff in evaluating these areas. PRA staff should be prepared to discuss the prioritization of structures, systems, and components (SSC) based on risk significance, as well as PRA-based insights related to the design. This information will help reviewers of other areas focus their review on safety-significant issues. In addition, PRA staff reviews Tier 1 to ensure appropriate treatment of important insights and assumptions from the PRA as described in Section C.II.1 of RG 1.206 and SRP Section 14.3. The organizations that are responsible for the review of the design of the plant for external natural hazards (e.g., earthquakes, high winds, external fires, external flooding), hazards related to human activities (e.g., transportation and local industry) and in-plant area hazards (internal fire and flooding) may
