NRC communications on IST, and information regarding current staff positions on IST. RG 1.192 as incorporated by reference in 10 CFR 50.55a addresses the acceptability of OM Code cases related to IST programs. RG 1.206 provides guidance for COL applicants to use in preparing applications to construct and operate their proposed nuclear power plants, including information for describing the functional design, qualification, and IST programs for pumps, valves, and dynamic restraints. In Section C.IV.9, “Regulatory Treatment of Nonsafety Systems,” of RG 1.206, the staff summarizes the Commission guidance provided in the Commission papers and SRMs on the treatment of RTNSS equipment in new reactors. The NRC staff prepared SRP Section 19.3 to provide high-level guidance for the evaluation of the scope of RTNSS equipment and its treatment that should be established by DC and COL applicants for nuclear power plants with passive post-accident heat removal systems. SRP Section 19.3 indicates that the NRC staff reviewer will verify that the applicant has provided sufficient information to address the regulatory criteria on RTNSS equipment. 3.9.6-14 Revision 4 – March 2017 As an alternative to deterministic IST programs, a risk-informed approach may be used to prioritize and adjust IST activities, such as the frequency of individual tests, selection of components to be tested, and IST testing approaches. The risk-informed IST program needs to provide reasonable assurance that components will remain capable of performing their intended functions until the next scheduled test. SRP Section 3.9.7 contains the acceptance criteria necessary for the review and their methods of application. In SRP Section 3.9.7, the NRC staff describes procedures and acceptance guidelines for its review of proposed plant- specific, risk-informed changes to a licensee’s IST program. The review procedures are consistent with acceptable methods implementing a risk-informed IST program that follow
