Content:
ances, the SFR-DC or mHTGR-DC may be more applicable to a design or technology than the ARDC. • The SFR-DC and mHTGR-DC are intended to apply to all designs of these technologies. Additional sets of technology-specific design criteria (e.g., MSRs, LFRs) may be developed in the future as more information about the designs becomes available. • Non-LWR designs should provide enhanced margins of safety and/or use simplified, inherent, passive, or other innovative means to accomplish their safety and security functions. DG-1330, Page 10 Harmonization with International Standards The International Atomic Energy Agency (IAEA), in collaboration with the International Project on Innovative Nuclear Reactors and Fuel Cycles and the Generation IV International Forum, established the Sodium-Cooled Fast Reactor Task Force. The SFR Task Force is collaborating with international designers, government organizations, and regulators to develop safety design criteria and safety design guidelines for SFRs. The NRC will continue to monitor and collaborate on these documents and consider using them to the extent practical in developing SFR design criteria. DG-1330, Page 11 C. STAFF REGULATORY GUIDANCE This section contains information on the intended use of the RG. It also contains NRC staff’s determination of the applicability of each GDC to the non-LWR design criteria. This is illustrated in the table titled, “Table 1: Non-Light-Water Reactor Crosswalk.” The actual ARDC, SFR-DC, and mHTGR- DC and NRC staff technology-specific rationale for adaptions to the GDCs to develop the PDC are contained in Appendices A-C to this RG. Intended Use of This Regulatory Guide This RG provides guidance to reactor designers, applicants, and licensees of non-LWR designs for developing PDC. Non-LWR applicants would not need to request an exemption from the GDC in 10 CFR Part 50 when proposing PDC for a specific design. Applicants may use this RG to develop all or part of the PDC and are free to
