Meeting Objectives

This Program Review will be focused on ongoing progress for each Technical Focus Area and discussion of path forward for the remainder of FY26.  Discussions will highlight:

  • Accomplishments to date and progress on key efforts
  • Issues/concerns related to meeting FY26 goals and M2 milestones
  • Potential collaboration with other NE programs
  • Initial thoughts on priorities for FY27 and beyond
  • Review participant questions

Program Vision

Through cross-cutting research and development and technology demonstration support, the Microreactor Program will enable broad deployment of microreactor technology by:

  • Achieve technological breakthroughs for key features of microreactors
  • Identifying and addressing technology solutions to improve the economic viability and licensing readiness of microreactors
  • Enable successful demonstrations of multiple domestic commercial microreactors

Program Objectives

  1.  Address critical, cross-cutting R&D needs that require unique national lab or university expertise or capabilities
  2. Develop R&D infrastructure to support design, demonstration, regulatory issue resolution, and M&S code validation
  3. Develop advanced technologies that enable improvements in microreactor viability
