2019-09089. Guidance for a Technology-Inclusive, Risk-Informed, and Performance-Based Methodology To Inform the Licensing Basis and Content of Applications for Licenses, Certifications, and Approvals for Non-Light Water Reactors
The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment draft regulatory guide (DG), DG-1353, “Guidance for a Technology-Inclusive, Risk-Informed, and Performance-Based Methodology to Inform the Licensing Basis and Content of Applications for Licenses, Certifications, and Approvals for Non-Light Water Reactors.” This DG proposes new guidance for designers, applicants, and licensees of non-light water cooled nuclear reactors (non-LWRs) to inform the licensing basis and content of applications submittals to the NRC for licenses, certifications, or approvals. The DG provides guidance on using a technology-inclusive, risk-informed, and performance-based methodology to inform the licensing basis and content of applications for licenses, certifications, and approvals for non-LWRs.
Submit comments by July 2, 2019. 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 DG, entitled “Guidance for a Technology-Inclusive, Risk-Informed, and Performance-Based Methodology to Inform the Licensing Basis and Content of Applications for Licenses, Certifications, and Approvals for Non-Light Water Reactors,” is a proposed new RG. The proposed new RG is temporarily identified by its task number, DG-1353. The proposed new RG endorses, with clarifications, the principles and methodology in NEI 18-Start Printed Page 1913304, “Risk-Informed Performance-Based Guidance for Non-Light Water Reactor Licensing Basis Development,” as one acceptable method for determining the appropriate scope and level of detail for parts of applications for licenses, certifications, and approvals for non-LWRs. NEI 18-04 outlines an approach for use by reactor developers to select licensing basis events; classify structures, systems, and components; determine special treatments and programmatic controls; and assess the adequacy of a design in terms of providing layers of defense in depth. The methodology described in NEI 18-04 and the draft RG also provide a general methodology for identifying an appropriate scope and depth of information to be provided in applications to the NRC for licenses, certifications, and approvals for non-LWRs.
Draft regulatory guide, DG-1353, if finalized as a new regulatory guide, would provide guidance for informing the licensing basis and content of applications for non-LWRs. The selection of licensing-basis events; classification and special treatments of structures, systems, and components; and assessment of defense in depth are fundamental to the safe design of non-LWRs. These activities also support identifying the appropriate scope and depth of information provided in applications for licenses, certifications, and approvals required under part 50 of title 10 of the Code of Federal Regulations (10 CFR), “Domestic Licensing of Production and Utilization Facilities,” and 10 CFR part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants.” The methodology outlined in DG-1353 and NEI 18-04 provide guidance intended to support the design and licensing of non-LWRs.
The DG, if finalized, would not constitute regulatory requirements. For this reason, issuance of DG-1353, 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 applications for licenses, certifications, or approvals. 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-1353 in final form would not constitute a violation of issue finality.
Dated at Rockville, Maryland, this 30th day of April, 2019.
