UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 March 26, 2021 MEMORANDUM TO: John P. Segala, Chief Advanced Reactor Policy Branch Division of Advanced Reactors and Non-Power Production and Utilization Facilities Office of Nuclear Reactor Regulation FROM: Jordan P.

SUMMARY

OF JANUARY 21, 2021, ADVANCED REACTOR STAKEHOLDER PUBLIC MEETING On January 21, 2021, the U.S. Nuclear Regulatory Commission (NRC) held a Category 2 public meeting with industry stakeholders, including the Nuclear Energy Institute (NEI) and the U.S.

Nuclear Industry Council (USNIC), to discuss ongoing initiatives related to the development and licensing of non-light-water reactors (non-LWRs). The staff has posted the meeting notice in the NRCs Agencywide Documents Access and Management System (ADAMS) at Accession No. ML21012A036 and the presentation slides at ADAMS Accession No. ML21019A462. Enclosure 1 lists the meeting attendees who participated remotely.

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.html#advSumISRA. The staff specifically noted the activities that have recently been completed, updated, or added since the November 5, 2020, advanced reactors stakeholder meeting.

The NRC staff provided feedback on NEIs input on regulatory priorities for new and advanced reactors (ADAMS Accession No. ML20353A393), dated December 18, 2020, which recommended establishing the following regulatory objectives to inform NRC priorities: (1) streamlining of regulatory processes needed to support the timely and efficient review and oversight of new and advanced reactors; (2) resolution of key generic technical or policy topics needed to support the review and approval of new and advanced reactor applications; and (3) changes to the regulations that are needed to achieve a more modern and efficient regulatory framework. The staff noted that they appreciate NEIs input and that the objectives are

J. Segala 2 consistent with NRCs vision and strategy for advanced reactor readiness, but some differences exist between the schedules recommended in NEIs letter and current NRC activities. The staff also noted that they will continue to seek input from stakeholders on ongoing and planned activities and that current staff priorities are focused on ongoing license application reviews, preapplication engagement reviews, activities required by the Nuclear Energy Innovation and Modernization Act (NEIMA), Commission directed rulemakings, and activities to prepare for new applications.

The NRC staff provided a summary of the key revisions to its draft white paper, Preapplication Engagement to Optimize Application Reviews (ADAMS Accession No. ML21014A267), which considered stakeholder feedback received at the November 5, 2020, public advanced reactor stakeholder meeting. The staff noted that the revisions provided additional clarifications in the areas of probabilistic risk assessment (PRA), regulatory exemptions, and environmental considerations discussed in the white paper. The staff discussed that the white paper will go through formal review and concurrence and that the final white paper will be posted on NRCs advanced reactor website following issuance.

The NRC staff presented on preapplication engagement for advanced reactor fuels to support advanced reactor readiness to license and certify fuel facilities, transportation packages, and spent fuel storage installations. The staff noted that they are proactively identifying potential technical challenges and information needs associated with the safe use of advanced reactor fuels being developed at higher enrichments. The staff discussed that the preapplication guidance is applicable to both potential non-LWR and LWR applicants planning on using fuels at higher enrichments. The staff encouraged applicants to have early engagements with the staff to ensure a common understanding of the regulatory issued.

Staff from Sandia National Laboratories (SNL) presented on its work associated with the incorporation of the HYSPLIT atmospheric transport and dispersion (ATD) model into MELCOR Accident Consequence Code System (MACCS) to advance ATD capabilities. SNL discussed the purpose of MACCS and challenges experienced with the use of the Gaussian plume model.

SNL discussed the evaluation and selection of HYSPLIT among other ATD models based on the inclusion of essential features and additional desirable features to increase ATD capabilities.

SNL noted that MACCS coupled with HYSPLIT has been implemented and verified and that the ability to incorporate the HYSPLIT ATD model results in MACCS is a major improvement in the capabilities of MACCS simulations and provides state-of-the-art alternative to the use of the Gaussian plume segment model. Stakeholders asked questions about the use of MACCS for near-field applications. SNL discussed that near-field applications was included in the release of MACCS 4.0. SNL provided a presentation on the use of MACCS for near-field applications at an NRC advanced reactor stakeholder meeting on October 1, 2020 (ADAMS Accession No. ML20350B457).

The NRC staff provided a status update regarding the plans and schedule to develop a regulatory guide (RG) endorsing the American Society of Mechanical Engineers / American Nuclear Society (ASME/ANS) advanced non-LWR PRA standard and NEI 20-09, Performance of PRA Peer Reviews Using the ASME/ANS Advanced Non-LWR PRA Standard. The staff discussed that they issued a draft white paper, Demonstrating the Acceptability of Probabilistic Risk Assessment Results Used to Support Advanced Non-Light Water Reactor Plant Licensing (ADAMS Accession No. ML21015A434), dated January 15, 2021, and are planning a public meeting in February or March 2021 to discuss the draft white paper in detail.

J. Segala 3 The U.S. Department of Energy (DOE) Gateway for Accelerated Innovation in Nuclear (GAIN) provided an overview of GAIN as a resource for accelerated development of nuclear innovations with laboratory partners. GAIN discussed how to do business with them through contact mechanisms and funding opportunities and provided an overview of recent voucher awards and the impact GAIN has made on the industry since it was established in 2015. GAIN discussed upcoming workshops and webinar series scheduled in 2021 and focused on multi-industry stakeholders. GAIN provided an overview of DOEs Office of Nuclear Energy (NE) strategic vision, with the goals of (1) enabling continued operation of existing U.S. nuclear reactors, (2) enabling the deployment of advanced nuclear reactors, (3) developing advanced nuclear fuel cycles, (4) maintaining U.S. leadership in nuclear energy technology, and (5) enabling a high-performing organization.

DOE-NE presented an overview of their Advanced Reactor Demonstration Program (ARDP),

which focuses DOE and non-federal resources on the actual construction of real demonstration reactors. DOE-NE discussed the ARDP program elements and that the Funding Opportunity Announcement (FOA) solicited applications under three funding pathways aligned with different maturity levels: Advanced Reactor Demonstration awards, Risk Reduction for Future Demonstration awards, and Advanced Reactor Concepts-20 awards. DOE-NE discussed the selected technologies for each award. DOE-NE noted that continued coordination with the NRC is needed to meet the aggressive deployment dates associated with these awards.

The NRC staff provided an update on its activities related to the NRCs review and endorsement of ASME Boiler and Pressure Vessel Code (BPVC)Section III, Division 5, High Temperature Reactors. The staff noted that they have received final contractor reports that provide expert recommendation on the technical adequacy of ASME Section III, Division 5 and have posted these reports on the NRCs advanced reactor public website: https://www.nrc.gov/reactors/new-reactors/advanced/details.html#endorev. The staff noted that they are drafting the NUREG and draft RG endorsing ASME Section III, Division 5. The staff expects the NUREG and draft RG to be published for public comment in the spring of 2021.

The meeting ended with an open discussion. The NRC requested feedback about how these meetings can be more engaging and how to increase participation by prospective applicants.

The staff discussed the various upcoming public meetings focused on advanced reactor initiatives, including Part 53. The next advanced reactors stakeholder meeting would be scheduled in late February 2021.
