or such other units.” Together, these requirements recognize that different requirements may be necessary for non- LWR designs. The non-LWR design criteria developed by the NRC staff and included in Appendices A to C of this regulatory guide, are intended to provide stakeholders with insight into the staff’s views on how the GDC could be interpreted to address non-LWR design features; however, these are not considered to be final or binding regarding what may eventually be required from a non-LWR applicant. It is the applicant’s responsibility to develop the PDC for its facility based on the specifics of its unique design, using the GDC, non-LWR design criteria, or other design criteria as the foundation. Further, the applicant is responsible for considering public safety matters and fundamental concepts, such as defense in depth, in the design of their specific facility and for identifying and satisfying necessary safety requirements. The non-LWR design criteria are an important first step to address the unique characteristics of non-LWR technology. The NRC recognizes the benefits to risk informing the non-LWR design criteria to the extent possible, depending on the design information and data available. The NRC’s draft “Vision and Strategy: Safely Achieving Effective and Efficient Non-Light-Water Reactor Mission Readiness” (Ref. 16) outlines mid- and long-term activities to develop, as necessary, a risk-informed, performance- based non-LWR regulatory framework. Implementing the mid- and long-term Implementation Action Plans as part of the Vision and Strategy activities will help NRC determine whether risk informed non- LWR design criteria should be included as part of a new regulatory framework. DOE-NRC Initiative Phase 1 In July 2013, the NRC and U.S. Department of Energy (DOE) established a joint initiative to address a key element in the regulatory framework that could apply to non-LWR technologies— specifically, to address the existing GDC, which
