NRCs Preparations for Advanced Reactor Licensing Wendy Reed Office of Nuclear Regulatory Research October 15, 2020 1

Outline

  • Overview of the NRC
  • Advanced Reactor Readiness at NRC
  • Research Activities
  • Update on Part 53 Rulemaking
  • Cooperation and Communication
  • Preparations for MSR Licensing 2

Overview of the NRC

  • Independent agency that began operations in 1975 Nuclear Radioactive Materials Waste
  • Headed by a five-member commission
  • Licenses and regulates activities in four key areas Nuclear Nuclear
  • Congressionally-mandated Reactors Security Office of Nuclear Regulatory Research supports key areas 3

Materials Integrity Strategy 2 Readiness Objectives

  • Assess performance needs/issues for materials and component integrity and build knowledge base
  • Identify gaps in knowledge, data, and assessment tools
  • Develop compendium of domestic and international operational experience
  • Develop guidance endorsing consensus standards 7

Strategy 2: Completed Activities International operational experience with SFRs and HTGRs, focused on materials and component integrity (ADAMS ML18353B121)

Technical Gap Assessment for Materials and Component Integrity Issues for Molten Salt Reactors (ADAMS ML19077A137)

Pathway to New Regulatory Framework

  • Part 53 NEIMA required rulemaking to establish a technology-inclusive, risk-informed and performance based regulatory framework

Builds on current activities including the Licensing Modernization Project

  • 1st public meeting held September 22, 2020
  • Staff Requirements Memorandum issued October 2, 2020 (ML20276A293)

Commission instructed staff to issue final rule by October 2024 10

NRCs Be Ready Attitude

  • Engagement with EPRI, National Labs, NEA
  • Improve mission value through cooperation Deliver cost savings Reduce duplication of effort Build staff expertise; e.g. NRAN program Bring regulatory perspectives to new ideas 11

Advanced Reactor Workshop December 9-11, 2019

  • MSR Topics Graphite Chemistry

Closing Thoughts

  • The vision and strategy for advanced reactors is being executed through the Implementation Action Plans.
  • The NRC plans to issue a final rule establishing a technology-inclusive, risk-informed and performance based regulatory framework for advanced reactors by October 2024
  • Communication and cooperation is key for effective and efficient licensing of molten salt reactor technologies 13
