Reforming Nuclear Reactor Testing at the Department of Energy

As I stated in Executive Order 14156 of January 20, 2025 (Declaring a National Energy Emergency), the United States needs a reliable, diversified, and affordable supply of energy to drive development of advanced technologies, manufacturing, transportation, agriculture, and defense industries, and to sustain modern life and national security. Nuclear energy both is vital to this effort and has never held so much promise. Decades of research and engineering have produced prototypes of advanced nuclear technologies that incorporate passive safety mechanisms, improve the physical architecture of reactor designs, increase reactor operational flexibility and performance, and reduce risk in fuel disposal. Advanced reactors—including microreactors, small modular reactors, and Generation IV and Generation III+ reactors—have revolutionary potential. They will open a range of new applications to support data centers, microchip manufacturing, petrochemical production, healthcare, desalination, hydrogen production, and other industries.

The United States cultivated the effort to design and build the first Generation IV reactor for commercial use, but the Federal Government has effectively throttled the domestic deployment of advanced reactors, ceding the initiative to foreign nations in building this critical technology. That changes today. It is the policy of my Administration to foster nuclear innovation and bring advanced nuclear technologies into domestic production as soon as possible.

(a) The term “advanced reactor” has the same meaning as the term “advanced nuclear reactor” in 42 U.S.C. 16271(b)(1).

(b) The term “Department” means the Department of Energy.

(c) The term “qualified test reactor” means an advanced reactor that satisfies thresholds established by the Department sufficient to demonstrate that, from the perspective of technical development and financial backing, the reactor may feasibly be operational within 2 years from the date a substantially complete application is submitted.

(d) The term “Secretary” means the Secretary of Energy.

(b) Within 90 days of the date of this order, the Secretary shall take appropriate action to revise the regulations, guidance, and procedures and practices of the Department, the National Laboratories, and any other entity under the Department's jurisdiction to significantly expedite the review, approval, and deployment of advanced reactors under the Department's jurisdiction. The Secretary shall ensure that the Department's expedited procedures enable qualified test reactors to be safely operational at Department-owned or Department-controlled facilities within 2 years following the submission of a substantially complete application.

(c) Upon finding that an applicant has submitted a substantially complete application for a qualified test reactor, the Secretary shall establish a team consisting of representatives from the Secretary's office, the relevant National Laboratory or Laboratories, the Department's Office of General Counsel, and any other entities within the Department that possess the authority to deconflict, oppose, or approve the application. The team shall provide assistance to the applicant to ensure expeditious processing of its application. For these purposes, each member shall report directly to the Secretary.

(d) The Secretary shall prioritize qualified test reactor projects for processing, as consistent with applicable law.

(b) Upon approval of an application for this pilot program, the Secretary shall assign a team to provide assistance to the applicant as specified in subsection 4(c) of this order.

(b) The Secretary shall, consistent with applicable law, use all available authorities to eliminate or expedite the Department's environmental reviews for authorizations, permits, approvals, leases, and any other activity requested by an applicant or potential applicant. In addition to the measures outlined in section 7 of the Executive Order of May 23, 2025 (Deploying Advanced Nuclear Reactor Technologies for National Security), such measures shall include determining which Department functions are not subject to NEPA, creating categorical exclusions as appropriate for reactors within certain parameters (or relying on existing categorical exclusions), relying on supplemental analyses where reactors will be located on existing sites, or utilizing alternative procedures under NEPA.

(i) the authority granted by law to an executive department or agency, or the head thereof; or

(ii) the functions of the Director of the Office of Management and Budget relating to budgetary, administrative, or legislative proposals.

(b) This order shall be implemented consistent with applicable law and subject to the availability of appropriations.

(c) This order is not intended to, and does not, create any right or benefit, substantive or procedural, enforceable at law or in equity by any party against the United States, its departments, agencies, or entities, its officers, employees, or agents, or any other person.

(d) The Department of Energy shall provide funding for publication of this order in the Federal Register .
