ppropriate to apply to the guidance development for non-LWRs.16 Efforts to establish a risk-informed, performance-based, technology-inclusive regulatory framework for non-LWRs included the development of several key guidance documents. These include guidance on adapting the general design criteria in 10 CFR Part 50, Appendix A, “General Design Criteria for Nuclear Power Plants,” for developing principal design criteria for non-LWR designs documented in RG 1.232. In addition, these also include the LMP described in the industry-developed guidance NEI 18-04, Revision 1, issued August 2019. NEI 18-04, Revision 1, was endorsed by the NRC in RG 1.233. NEI 18-04, Revision 1, provides a systematic, risk-informed, and technology-inclusive process for developing key inputs for the content of applications to improve the understanding of the 2 The NRC encourages LWR applicants proposing to use the risk-informed, performance-based process described in NEI 21-07, Revision 1, to engage in pre-application discussions with the NRC to provide information to the staff on its intended implementation of the NEI 21-07, Revision 1 methodology for its design. 3 The staff has provided guidance on which regulations apply to non-LWRs in Appendix B of the advanced reactor content of application project (ARCAP) Roadmap interim staff guidance (ISG) document, DANU-ISG-2022-01, “Review of Risk Informed, Technology Inclusive Advanced Reactor Applications—Roadmap” (Ref. 16). DG-1404, Revision 1, Page 7 safety and risk significance of system designs and the relationship of system functions to overall facility safety, specifically for non-LWR designs. A key element of this new and flexible regulatory framework is to standardize the development of non-LWR application content to promote uniformity among applicants, support staff review consistency and predictability, and provide a well-defined base for evaluating proposed changes in review scope and requirements. The development of an
