sults, such that the PRA can be used in regulatory decision-making for light-water reactors (LWRs). • RG 1.206, “Applications for Nuclear Power Plants” (Ref. 10), provides guidance on the format and content of applications for nuclear power plants submitted to the NRC under 10 CFR Part 52, which specifies the information to be included in an application. This RG applies to power reactors with LWR technology. The NRC staff also considers this RG to generally apply to other types of power reactors (e.g., NLWRs). The NRC staff considers this guidance acceptable to support preparation of applications for ESPs, standard DCs, and COLs under 10 CFR Part 52 and generally acceptable to support its review of other types of applications under 10 CFR Part 52. • RG 1.233, “Guidance for a Technology-Inclusive, Risk-Informed, and Performance-Based Methodology To Inform the Licensing Basis and Content of Applications for Licenses, Certifications, and Approvals for Non-Light Water Reactors” (Ref. 11), provides guidance to inform the licensing basis and content of applications for NLWRs, including, but not limited to, molten salt reactors, high-temperature gas-cooled reactors, and a variety of fast reactors of different thermal capacities. NLWR applicants may use this guidance when applying for permits, licenses, certifications, and approvals under 10 CFR Part 50 and 10 CFR Part 52. RG 1.233 endorses the Licensing Modernization Project (LMP) guidance provided in Nuclear Energy Institute (NEI) 18-04, “Risk-Informed Performance-Based Technology Guidance for Non-Light Water Reactors” issued August 2019 (Ref. 12). • DC/COL-ISG-028, “Assessing the Technical Adequacy of the Advanced Light-Water Reactor Probabilistic Risk Assessment for the Design Certification Application and Combined License Application,” issued November 2016 (Ref. 13), provides guidance on how to adapt the American Society of Mechanical Engineers (ASME)/American Nuclear Society (ANS) PRA standard
