ARDC are intended to be technology neutral and, therefore, could apply to any type of non-LWR design. In addition to the technology-neutral ARDC, DOE proposed two sets of technology-specific, non-LWR design criteria. These criteria are intended to apply to SFRs and mHTGRs and are referred to as the SFR design criteria (SFR-DC) and the mHTGR design criteria (mHTGR-DC), respectively. The DOE developed the technology specific design criteria to demonstrate how the GDC could be adapted to specific technologies in which there was some level of maturity and documented design information available. DOE determined that the safety objectives for some of the current GDC did not address design features specific to SFR and mHTGR technologies (e.g., sodium or helium coolant, passive heat removal systems, etc.). Additional design criteria were developed to address unique features of those designs. DOE-NRC Initiative Phase 2 After DOE issued its report in December 2014, an NRC multidisciplinary team was assembled to review the report, other pertinent references, and NRC documents, such as NUREGs, reports, and white papers. The NRC held a public meeting on January 21, 2015, to discuss the report with DOE and to describe NRC’s plans to develop regulatory guidance for non-LWR reactor design criteria (Ref. 18). During its review, the NRC staff formulated questions and clarifications necessary to obtain a full understanding of the design aspects of the non-LWR technologies and the reasoning that DOE employed in developing its proposal for the ARDC, SFR-DC, and mHTGR-DC. The following documents contain the NRC questions and DOE responses: • “NRC Staff Questions on the DOE Report, ‘Guidance for Developing Principal Design Criteria for Advanced Non-Light Water Reactors,’” dated June 5, 2015, and “Response to NRC Staff Questions on the U.S. Department of Energy Report, ‘Guidance for Developing Principal Design Criteria for Advanced Non-Light Water Reactors,’” dated
