gy-inclusive methodology in NEI 21-07, Revision 1, provides a common approach to identifying and describing the scope and level of detail for the fundamental safety functions of a design necessary for developing the safety analysis for the design. The applicant is also responsible for demonstrating compliance with all applicable regulations and may request exemptions, as appropriate, to establish the licensing basis for the design.3 Background As the NRC prepares to review and regulate a new generation of non-LWRs, the staff has recognized both the need to establish a flexible regulatory framework and the benefits of such a framework. The NRC described its efforts to prepare for possible licensing of non-LWR technologies in “NRC Vision and Strategy: Safely Achieving Effective and Efficient Non-Light Water Reactor Mission Readiness,” issued December 2016 (Ref. 11). In “NRC Non-Light Water Reactor Near-Term Implementation Action Plans,” issued July 2017 (Ref. 12), and “NRC Non-Light Water Reactor Mid-Term and Long-Term Implementation Action Plans,” issued July 2017 (Ref. 13), the NRC staff identified specific activities the agency would conduct in the near-term, mid-term, and long-term timeframes. In addition, the Commission encouraged the use of a performance-based, technology-inclusive licensing framework for small modular reactors in SRM-COMGBJ-10-0004/COMGEA-10-0001, “Staff Requirements— COMGBJ-10-0004/COMGEA-10-0001—Use of Risk Insights to Enhance Safety Focus of Small Modular Reactor Reviews,” dated August 31, 2010 (Ref. 14), and SRM-SECY-11-0024, “Staff Requirements—SECY-11-0024—Use of Risk Insights to Enhance the Safety Focus of Small Modular Reactor Reviews,” dated May 11, 2011 (Ref. 15). The NRC staff believes that this approach is appropriate 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
