Content:
w in the design control document (DCD) is contained in Appendix A to this SRP. The PRA for site-specific portions of the design will be evaluated during the combined license review. PSGB: Reviews Tier 1 to ensure appropriate treatment of security issues. Reviewers should use the guidance in SRP Chapter 13 related to security issues to determine the appropriate top-level design features for inclusion in Tier 1 and provide inputs to the responsible review branches. Programmatic and site-specific aspects of security are considered as part of a combined license application. II. ACCEPTANCE CRITERIA The acceptance criteria for ITAAC are based on meeting 10 CFR §52.97(b)(1), which sets forth the comprehensive requirements for ITAAC. For design certification reviews, the scope of ITAAC is limited to the scope of the certified design as required by 10 CFR §52.47(b). III. REVIEW PROCEDURES Preparation for the review of ITAAC should include the following: 1. Complete the review of the structures, systems and components (SSCs) before beginning the review of ITAAC. If the ITAAC review is begun before the significant issues are resolved, then the ITAAC may have to be revised. Also, review the latest version of the Safety Evaluation Report (SER) and Tier 2 for the purpose of familiarization with the facility design and its nomenclature. 2. Review the applicable regulations, SRP sections, regulatory guides (RGs), unresolved safety issues (USIs), and generic safety issues (GSIs), NRC generic correspondence, industry operating experience, NRC inspection programs, and any additional regulatory guidance from the Commission, for the purpose of determining the safety significance of SSCs. Also review NRC generic communications and operating experience discussed in Tier 2 to achieve familiarity with how these issues were resolved on a design-specific basis and their safety significance. 3. Review the DCD for the evolutionary design similar to the current design, specifically the Tier 1
