ance program), 10 CFR 50.49 (electric equipment environmental qualification program), 10 CFR 50.55a (code design, inservice testing and inservice inspection programs), 10 CFR 50.65 (maintenance rule), Technical Specifications (TSs), Availability Controls for SSCs subject to Regulatory Treatment of Non-Safety Systems (RTNSS), the Initial Test Program (ITP), and ITAAC. In preparing the safety evaluation for the application, the staff may use the satisfaction of these selected requirements to augment or replace, as appropriate, technical analysis and other evaluation techniques to obtain reasonable assurance that the performance-based acceptance criteria are satisfied. Under the framework, the staff also has the flexibility to use these selected requirements to demonstrate satisfaction of design-based acceptance criteria for the SSCs with low risk significance. The staff will verify the demonstration of the design-basis capabilities of SSCs that are important to safety as part of the ITAAC completion review prior to plant operation. The integrated process described in NEI 18-04 and its consideration of plant capabilities and programmatic controls for non-LWRs is well suited to inform the content of applications, including discussions of appropriate performance-based controls of ancillary SSCs, thereby reducing the level of detail in the descriptions of the physical systems. The general guidance on the content of applications provided in the RG will need to be supplemented by other RGs and documents to help non-LWR developers and the NRC staff prepare and review applications for licenses, certifications, and approvals. DG-1353, Page 26 D. IMPLEMENTATION The purpose of this section is to provide information on how non-LWR applicants and licensees10 may use this guide and information regarding the NRC’s plans for using this RG. In addition, it describes how the NRC staff complies with 10 CFR 50.109, “Backfitting,” and any applicable finality provisions in 10 CFR
