Strategic overview of advanced reactor fuels activities Robert Taylor Deputy Office Director for New Reactors, Office of Nuclear Reactor Regulation (NRR) 3

Enabling the safe and secure use of Enrichment l Fuel Fabrication l Transport l advanced reactor In-reactor Requirements l Spent Fuel Storage fuels 4

Enhancing technical readiness Develop and update fuel analysis codes Retain, develop, and recruit highly qualified staff Enhance knowledge 5

Optimizing regulatory readiness Data and risk insights to improve review and licensing efficiency.

Maintaining focus on safety.

Technology inclusive regulatory framework.

Flexible and practicable for a variety of technologies.

Recent Licensing Activities - TRISO Fuel Qualification Vendor Specific Topical Reports Preapplication Engagements Generic Topical Report for TRISO Fuel Particles 11

Readiness for the review of applications relating to the front-end and back-end of the advanced reactor fuel cycle Jason Piotter Senior Project Manager, Division of Fuel Management, Office of Nuclear Material Safety and Safeguards (NMSS) 12

Readiness to License Advanced Fuels Licensing Experience Challenges Data Preliminary Technical Evaluations Guidance Research Regulatory Framework 13

Current Licensing and Certification for Advanced Fuels Fuel Fabrication Transportation 14

Looking Forward: Potential Regulatory Needs

  • Critical Experiments Fuel Cycle
  • Code Validation
  • Operations Front End Advanced Fuels
  • Security Roadmap
  • Critical Experiments Transportation
  • Code Validation
  • Source Terms Fuel Cycle
  • Criticality & Shielding
  • Thermal & Materials Back End
  • Operations 15

International safeguards considerations Mirabelle Shoemaker International Safeguards Analyst, Division of Fuel Management, NMSS 16

Promoting Nuclear Nonproliferation Through Safeguards Implementation Committing to safeguards implementation in foreign agreements.

Incorporating safeguards measures in the regulatory framework.

Leading and cooperating within the network of safeguards implementation.

17

Using the Regulatory Framework to Implement Safeguards for Advanced Fuels Domestic and International Safeguards regulations are in place to support safeguards implementation at advanced fuel facilities NMMSS is ready to receive data from the advance reactor and fuel cycle licensees The NRC has published MC&A guidance for Category II facilities in support of regulatory compliance 18

Engaging with Domestic and International Partners Domestic Safeguards

  • DOE & national lab collaboration
  • Subgroup for Implementation of Safeguards in the US (SISUS)
  • US Interagency (Departments of State and Energy/National Nuclear Security Administration)

International Safeguards

  • International Atomic Energy Agency (IAEA)
  • Nuclear Cooperation Authorities Group (NCAG) 19

Research activities supporting the advanced reactor fuel cycle and modelling and simulation tools to prepare for advanced reactor fuels Wendy Reed Metallurgist, Division of Engineering, Office of Nuclear Regulatory Research 20

Independent Analysis for Advanced Fuel Qualification Development of TRISO fuel models for FAST and enhancement of existing metallic fuel capabilities to perform code assessments Assessment revealed FAST is ready for metallic and TRISO fuel analysis Further enhancements to reduce uncertainties INL/EXT-21-64279 Engagement with DOE on latest data and code developments Monitor future technologies for advanced fuel assemblies 21

Support for Advanced Fuel Cycle Regulatory Readiness Preliminary assessment of front-end activities for molten salt reactors Holistic approach to assessing Modelling and simulation to assess uncertainty in MC&A technical measurements considerations Integration of Safeguards-Security-Safety by design 22

Forward Thinking on the Advanced Fuel Cycle Back-end Enhance knowledge Improve of unique waste understanding of Monitoring ARPA-E streams and off-gas and DOE programs potential novel management for waste forms molten salt reactors 23
