It seeks to move qualified test reactors from application to operation within two years and expand testing beyond National Laboratories.

What the order does

  • Directs the Department of Energy to define qualified test reactors within 60 days and overhaul its approval processes within 90 days.
  • Requires expedited procedures designed to make qualified test reactors operational at Department-owned or Department-controlled facilities within two years of a substantially complete application.
  • Creates applicant-assistance teams reporting directly to the Energy Secretary and prioritizes qualified projects.
  • Establishes a pilot program for reactors outside National Laboratories, with at least three approvals and a goal of achieving criticality by July 4, 2026.
  • Orders changes to the Department’s environmental-review rules and directs it to eliminate or expedite reviews where legally permitted.
  • Directs coordination with the Department’s DOGE Team Lead, Office of Management and Budget, Office of Science and Technology Policy, and Council on Environmental Quality.

Who it affects

  • Advanced nuclear reactor developers seeking Department of Energy authorization or support.
  • National Laboratories and other Department of Energy facilities involved in reactor review, construction, or testing.
  • Communities and industries near proposed Department-controlled or off-laboratory reactor sites.

Context

The order treats Department-controlled advanced reactors that do not produce commercial electricity as research projects under Department of Energy jurisdiction, without changing Department of Defense authority.
