NEI 18-04 thereby defines a methodology for non- LWR applicants to identify and provide the appropriate level of information needed to satisfy parts of the regulatory requirements in 10 CFR 50.34, 10 CFR 52.47, 10 CFR 52.79, 10 CFR 52.137, and 10 CFR 52.157.9 The staff finds it more appropriate to define a technology-inclusive methodology for non-LWRs than to develop prescriptive content guidance as was developed for LWRs and documented in RG 1.70 and RG 1.206. The following guidance is acceptable for non-LWR designers in preparing the 9 This guidance focuses on the design features, programmatic controls, and licensing decisions related to limiting the unplanned release of radioactive material resulting from plant transients and postulated accidents. Various NRC regulations and related guidance address radiological effluents from normal operation and the content of applications provided in licensing basis documents other than Final Safety Analysis Reports (e.g., security plans, technical specifications, and environmental reports). RG 1.206 describes various licensing basis documents and a typical organization of those documents within applications for a combined license, early site permit, or design certification. The overall organization of applications described in RG 1.206, including chapter-level organization of a final safety analysis report, is generally applicable to non-LWR applications.

For ease of discussion, the following descriptions refer to the traditional chapter-level format of RG 1.206. Non-LWR designers may choose to arrange the information in a safety analysis report in a different format. The general guidance on the methodology to determine the appropriate content and level of detail for safety functions,
