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 tests for testing in lieu of ITAAC. f. Ensure that the ITAAC emphasize testing of the as-built facility and use the definitions for testing provided in this guide. g. Ensure that the ITAAC include SSCs for which the features or functions are necessary to satisfy the NRC’s regulations in 10 CFR Part 20, “Standards for Protection against Radiation”; 10 CFR Part 50; 10 CFR Part 73, “Physical Protection of Plants and Materials”; or 10 CFR Part 100, “Reactor Site Criteria.” h. Ensure that ITAAC include severe accident design features and plant features designed for protection against hazards. i. Ensure that ITAAC include SSCs determined to be risk significant under SRP Section 19.3, “Regulatory Treatment of Nonsafety Systems for Passive Advanced Light Water Reactors.” The NRC staff is particularly interested in ensuring that the ITAAC adequately consider the assumptions and insights from key safety and integrated plant safety analyses in the FSAR under which plant performance depends on contributions from multiple systems of the facility design. Addressing these assumptions and insights in ITAAC ensures that the as-built facility preserves the integrity of the fundamental analyses for the facility design. These analyses include flooding, overpressure protection, containment, core cooling, fire protection, transients, anticipated transient without scram, steam generator tube rupture (pressurized-water reactors only), radiological concerns, unresolved safety issues, generic safety issues, Three Mile Island action plan items, or other key analyses specified by the NRC staff. The applicant should consult RIS 2008-05, “Lessons Learned to Improve Inspections, Tests, Analyses, and Acceptance Criteria Submittal,” Revision 1, dated September 23, 2010, (Ref. 90)
