Update on White Paper for Scalable Human Factors Engineering and Flexible Staffing for Advanced Reactors; and Draft Regulatory Guide to Endorse American Society of Mechanical Engineers (ASME)
Code Section XI, Division 2, Reliability and Integrity Management (RIM) Programs for Non-Light Water Reactors.
The meeting notice is available in the NRCs Agencywide Documents Access and Management System (ADAMS) at Accession No. ML21257A351, and the presentation slides are available at
S. Lynch 2 ADAMS Accession No. ML21274A076. The Enclosure to this summary provides the attendees for the meeting as captured by Microsoft Teams.
For each topic listed above, the NRC staff provided information and allotted time for stakeholder comments and questions. Stakeholders provided feedback on several of the topics and asked clarifying questions. NRC staff stated that the feedback was appreciated.
The NRC staff provided an overview of the Advanced Reactor Integrated Schedule of Activities on the NRCs public website at https://www.nrc.gov/reactors/new-reactors/advanced/details#advSumISRA. The NRC staff specifically noted the activities that have recently been completed, updated, or added since the August 26, 2021, advanced reactor stakeholder meeting.
The NRC staff gave an overview of the recently published draft white paper on micro-reactor licensing approaches/strategies within existing regulations (ADAMS Accession No. ML21235A418). One stakeholder questioned whether micro-reactors are a subset of advanced non-light-water reactor designs, as stated in the BACKGROUND section of the paper, or whether the approaches in the paper could be applied to LWRs. In response, the NRC staff stated that the approaches in the paper could be applied to LWRs and that it would be appropriate to remove non-light-water from the statement. Another question was if the biggest policy issue identified in the white paper is the operational programs issue and whether it will be brought up to the Commission. The NRC staff stated the operational programs policy issue is important, but there are also other important policy issues discussed in the white paper involving manufacturing licenses (e.g., starting up reactors in a factory). The NRC staff also responded that policy issues are being considered as part of the Part 53 rulemaking. The NRC staff could also issue separate SECY papers on specific topics. One stakeholder asked if radioactive waste after the end-of-life of a reactor is considered in the environmental review. The NRC staff confirmed that these impacts are considered in the review. A revised draft of the paper will be published.
The Idaho National Laboratory (INL) summarized its report INL-EXTEXT-21 -61847, Regulatory Research Planning for Micro Micro-Reactor Development, and discussed regulatory and licensing challenges involving microreactors. A limited-scope Regulatory Research Development Plan (RRDP) has been developed to link important advanced non-light-water nuclear microreactor technology research and development activities sponsored by the Department of Energys Office of Nuclear Energy with regulatory requirements and critical licensing needs likely to impact the deployment of a domestic commercial microreactor fleet.
INL and Oak Ridge National Laboratory (ORNL) staff continue to seek new and updated needs to support the development and deployment of microreactors. The U.S. Nuclear Industry Council (USNIC) commented that gaps remained between Title 10 of the Code of Federal Regulations (10 CFR) Parts 71, 50 and 52 and that these need to be addressed.
The NRC staff presented a summary of technical reports on transportation and storage of advanced reactor fuels, including a systematic assessment process for these fuels. The process surveyed the state of knowledge, identified information needs, determined the approach to address needs, and initiated the appropriate action. Key messages included: the sufficiency of the current regulatory framework for applications for advanced reactor fuels, the potential for enhancement in certain topic areas for higher quality applications and efficient, effective reviews, the wide variability in potential designs, and the importance of preapplication meetings.
S. Lynch 3 On its draft white paper, Advanced Reactor Content of Application (ARCAP) Guidance for Fire Protection (Operations), the NRC staff stated that the purpose of this ARCAP white paper guidance document (Internal Staff Guidance or ISG) was to facilitate the review of advanced reactor applications that use a risk-informed, performance-based approach to develop their fire protection programs. The guidance in this ARCAP white paper ISG can be applied to any non-LWR, SMR or stationary micro-reactor applying for an operating license (OL) or combined license (COL) under 10 CFR Parts 50 or 52. The NRC staff noted that the white paper guidance was developed considering the 10 CFR Part 53 rulemaking that is underway. As the 10 CFR Part 53 requirements are developed, this ISG will be supplemented, as necessary, to provide guidance for developing fire protection programs to reflect any differences in requirements between 10 CFR Parts 50/52 and 10 CFR Part 53.
The NRC staff and Canadian Nuclear Safety Commission (CNSC) staff provided an overview of joint NRC-CNSC report on technology inclusive and risk-informed reviews for advanced reactors. Since the initiation of a Memorandum of Cooperation (MOC) in August 2019, the NRC and CNSC completed a joint report comparing the technology-inclusive, risk-informed NRC and CNSC review approaches for advanced reactors. Specifically, the review focused on the Licensing Modernization Project (LMP) process endorsed by NRC in Regulatory Guide (RG) 1.233, 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. Key messages and observations from the report were noted, including: both the Canadian and U.S. regulatory approaches effectively protect the health and safety of the public and the environment during nuclear power plant operation; both approaches include some degree of technology-inclusive, risk-informed, performance-based review; although consistent at a high level, NRCs LMP approach uses PRA more extensively while CNSCs approach considers other factors in decision making (operating experience, regulatory authority input, etc.). One stakeholder commented that the regulatory process should be simplified for vendors applying for licenses in both countries. Another stakeholder asked if Canada has voluntary consensus standards, and if there will be harmonization between U.S. and Canada on this matter. CNSC responded by saying Canada accepts ASME codes that are used in the U.S., however, Canada does not have a regulatory process for endorsement similar to the NRC regulatory guide process.
The NRC staff provided an update on draft NUREG-2246, Fuel Qualification for Advanced Reactors." NUREG-2246 provides a framework for evaluating a nuclear fuel design and attempts to enable a transparent, efficient, and thorough safety review. It is informed by the NRC staff experience gained from licensing solid fuel reactor designs (particularly LWR designs), advanced reactor fuel testing performed to-date, and the accelerated fuel qualification (AFQ) considerations and focused on areas where irradiated fuel tests have been required. The NRC staff primarily focused on responding to NEI comments on this document. The NRC staff discussed on-going work with the national labs to exercise the NUREG-2246 framework for metal fuel and tristructural isotropic (TRISO) fuel forms, and provided updates on on-going work associated with molten salt reactor fuel qualification guidance. A Full Committee meeting of the Advisory Committee on Reactor Safeguards (ACRS) is tentatively scheduled for November 2021; the final NUREG-2246 is expected to be issued in January or February of 2022.
The NRC staff provided an update on a white paper for scalable human factors engineering (HFE) and flexible staffing reviews for advanced reactors. The NRC staff contracted Brookhaven National Laboratory (BNL) to develop a technical basis and method for scaling the scope and depth of HFE reviews for advanced reactors. The method enables the NRC staff to readily adjust the focus and level of HFE review based upon risk / safety insights and the unique
S. Lynch 4 characteristics of the facility design and operation. The NRC staff is currently using the BNL research to draft guidance for development of application-specific HFE review plans.
Concurrently, the NRC staff is also developing guidance appropriate for the review of the wide range of staffing plans that the NRC staff anticipates receiving in conjunction with advanced reactor license applications. Although the guidance does not presume the need for an exemption request, it will build upon the technical guidance in NUREG-1791, Guidance for Assessing Exemption Requests from the Nuclear Power Plant Licensed Operator Staffing Requirements Specified in 10 CFR 50.54(m).
The NRC staff made a presentation on its draft regulatory guide DG-1383, Acceptability of ASME Code,Section XI, Division 2, Requirements for Reliability and Integrity Management (RIM) Programs for Nuclear Power Plants for Non-Light Water Reactors. The objectives of this NRC staff presentation included the following: alert stakeholders that DG1383 is publicly available for comment; provide an overview of the NRC staffs review of ASME Code,Section XI, Division 2; familiarize stakeholders with ASME Code,Section XI, Division 2 (RIM); present the unique regulatory aspects of preservice and inservice inspection programs for advanced reactors; identify the conditions the NRC staff has recommended in DG-1383 on the use of ASME Code,Section XI, Division 2; and communicate plans for the public comment period and development of the final regulatory guide (RG). The NRC staff discussed the structure of DG-1383 (future RG 1.246) covering the following: purpose, applicability (non-LWRs),
regulations and related guidance; background and bases for NRC staff positions; and staff regulatory guidance with 15 conditions. The NRC staff briefly discussed each of the 15 conditions.
