Submit comments by April 4, 2017. Comments received after this date will be considered if it is practical to do so, but the NRC is able to ensure consideration only for comments received on or before this date. Although a time limit is given, comments and suggestions in connection with items for inclusion in guides currently being developed or improvements in all published guides are encouraged at any time.

The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment draft regulatory guide (DG), DG-1330, “Guidance for Developing Principal Design Criteria for Non-Light Water Reactors.” This DG is a proposed new regulatory guide (RG) to provide designers, applicants, and licensees of non-light water cooled nuclear reactors (non-LWR) guidance for developing principal design criteria (PDC) for a proposed facility. The PDC establish the necessary design, fabrication, construction, testing, and performance requirements for structures, systems, and components important to safety; that is, structures, systems, and components that provide reasonable assurance that the facility can be operated without undue risk to the health and safety of the public.

The DG, entitled “Guidance for Developing Principal Design Criteria for Non-Light Water Reactors,” is a proposed new RG. The proposed new RG is temporarily identified by its task number, DG-1330. The proposed new RG describes the NRC's proposed guidance on how the general design criteria (GDC) in Appendix A, “General Design Criteria for Nuclear Power Plants,” of title 10 of the Code of Federal Regulations, part 50, “Domestic Licensing of Production and Utilization Facilities” (10 CFR part 50) apply to non-LWR designs. This guidance may be used by non-LWR reactor designers, applicants, and licensees to develop PDC for non-LWR designs, as required by 10 CFR part 50 for an application for a construction permit, and 10 CFR part 52 for an application for a design certification, combined license, standard design approval, or manufacturing license. The DG also describes the NRC's proposed guidance for modifying and supplementing the GDC to develop PDC that address two specific non-LWR design concepts: sodium-cooled fast reactors (SFRs), and modular high temperature gas-cooled reactors (mHTGRs).
The advanced reactor design criteria (ARDC) are intended to be technology-neutral and, therefore, could apply to any type of non-LWR design. In July 2013, the NRC and U.S. Department of Energy (DOE) established a joint initiative to review and address the existing GDC, which may not directly apply to non-LWR power plant designs. During the review it was determined that the safety objective for some of the current GDC were not applicable to SFR and mHTGR technologies, so entirely new design criteria were developed to address their unique design features.
The purpose of DG-1330 is to provide regulatory guidance to assist future applicants in developing PDC for non-LWR designs. The NRC approves the PDC, which form part of the licensing basis for the facility. The DG, if finalized, would not constitute regulatory requirements. For this reason, issuance of DG-1330, if finalized, would not constitute backfitting under 10 CFR 50.109 (the “Backfit Rule”). Future applicants may choose to follow the guidance or utilize another approach in developing principle design criteria for their facilities. Applicants and potential applicants are not, with certain exceptions, protected by either the Backfit Rule or any issue finality provisions under 10 CFR part 52. Neither the Backfit Rule nor the issue finality provisions under 10 CFR part 52—with certain exclusions discussed below—were intended to apply to every NRC action which substantially changes the expectations of current and future applicants. Therefore, the positions in any regulatory guide, if imposed on applicants under 10 CFR 50.34(a)(3), 52.47(a)(3), 52.79(a)(4), 52.137(a)(3), or 52.157(a), would not represent backfitting or a violation of issue finality (except as discussed below).
The exceptions to the general principle are applicable whenever a combined license applicant references a 10 CFR part 52 license (i.e., an early site permit or a manufacturing license) and/or 10 CFR part 52 regulatory approval (i.e., a design certification rule or design approval). There are no current non-LWR applicants or holders of licenses or design certifications for non-LWR designs. Therefore, issuance of DG-1330 in final form would not constitute a violation of issue finality.
