n general, the specific code edition, volume, version, date, and other such information should be specified in the FSAR rather than in the ITAAC or Tier 1 of the DCD. Inspections, Tests, Analyses, and Acceptance Criteria Design Descriptions The ITAAC design descriptions, if provided, are derived solely from the detailed design information in the COL FSAR and should address the essential top-level design information and performance characteristics that the NRC staff relies on as the bases for its safety review of the design. The type of information and the level of detail included in the ITAAC and ITAAC design descriptions for each SSC are based on a graded approach (SECY-90-377) that is commensurate with the risk- and safety-significance of the facility’s SSCs. Top-level design information selected for verification in the ITAAC should contain the principal performance characteristics and safety functions of the SSCs, their important features in various safety analyses, and their functions for defense-in-depth considerations. The COL applicant should do the following in its development of proposed ITAAC and ITAAC design descriptions: a. Carefully consider design-specific and unique features of the facility for inclusion in ITAAC. b. Ensure that the ITAAC reflect the important insights and assumptions from the PRA with respect to the risk- and safety-significance of SSCs. c. Ensure that the ITAAC reflect the resolutions of technically relevant unresolved safety issues and generic safety issues, NRC generic correspondence (such as bulletins and generic letters), and relevant industry operating experience. d. Ensure that the ITAAC are consistent with the technical specifications, including their bases and LCOs. DG-1325, Page-77 e. Ensure that the ITAAC are consistent with the preoperational test program described in FSAR Section 14.2 because many of the preoperational tests for SSCs may be used to satisfy ITAAC. However, the applicant should not rely on preoperational
