T SSCs whose reliability and capabilities have not been confirmed at the CP stage, the application should include a discussion in the SAR on how the applicant intends to confirm, at the OL stage, that reliability and capability performance targets have been met. The application should describe any testing and validation planned to confirm NRST SSC performance capabilities and availability, including any special treatment to be applied to the NSRST SSCs. As discussed earlier, Chapter 6 of the SAR establishes DBHL requirements and identifies design parameters for NSRST and NST SSCs. C.8 Staff Position: NEI 21-07, Revision 1, Section C.7, provides an acceptable method for developing information related to the special treatment requirements for NSRST SSCs and the descriptions and capabilities of NSRST SSCs. Table 4-1 of NEI 18-04, Revision 1, gives additional information on the types of special treatments that may be considered for SSCs. 11 “Design Review Guide (DRG): Instrumentation and Controls for Non-Light Water Reactor (Non LWR) Reviews,” dated February 26, 2021 (Ref. 43) provides guidance to the NRC staff for review of this topic. The DRG is intended to make information about regulatory matters widely available and to improve communication among the NRC, interested members of the public, and the nuclear power industry, thereby increasing understanding of the NRC’s review process. DG-1404, Revision 1, Page 27 a. Addition: In addition to the material identified in NEI 21-07, Revision 1, Section C.7, preparation of Chapter 7 of the SAR should also consider the following: (1) If the facility includes instrumentation and control systems identified as NSRST, the applicant should describe the special treatments applied to the I&C systems and components and analyze their capability to perform their credited functions.13 9. Plant Programs Section C.8 of NEI 21-07, Revision 1, provides guidance on the information related to plant programs that support the LMP-based
