Actions to Address Executive Order 14300: Reforming the Nuclear Regulatory Commission

December 12, 2025 Category: Policy, Technology Work Area: Advanced Nuclear

Introduction and Summary of Executive Order 14300

Executive Order 14300, Reforming the Nuclear Regulatory Commission, represents a fundamental shift in how the federal government directs the licensing and regulation of civilian nuclear energy. The order is premised on the argument that abundant energy is a core component of national and economic security, and that nuclear power, in conjunction with domestic fossil fuels, is essential to U.S. resilience in the face of geopolitical competition. The Administration highlights the stark contrast between the nation’s past and present licensing trajectories: between 1954 and 1978, the United States authorized the construction of 133 reactors, while since 1978 only two have entered commercial operation. According to the order, the NRC’s reliance on protracted licensing timelines and its practice of charging applicants hourly fees has stifled the deployment of nuclear power and hindered innovation.

The Executive Order reframes the NRC’s mission. Rather than focusing exclusively on risk minimization, the Commission is directed to weigh the benefits of nuclear energy to economic and national security alongside traditional safety, health, and environmental considerations. This reorientation is closely tied to recent legislation, especially the Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy Act of 2024 (ADVANCED Act), which required NRC to regulate in a manner that does not unnecessarily limit nuclear deployment.

To implement this vision, the order mandates organizational and regulatory reforms across several fronts. Structurally, the NRC is directed to reorganize in consultation with the Administration’s Department of Government Efficiency (DOGE) team, reappropriating staff in areas deemed misaligned with the new mission while expanding capacity in new reactor licensing. A 20-member team must be established to lead the drafting of new regulations, while the Advisory Committee on Reactor Safeguards is to be reduced to the statutory minimum necessary for its functions.

On the regulatory front, the order calls for a wholesale review and revision of NRC’s regulations and guidance. Proposed rules must be issued within nine months of the order, and final rules within eighteen months. These reforms include the establishment of binding licensing deadlines: no more than eighteen months for decisions on new reactor applications and no more than twelve months for license renewals. NRC fee recovery is capped to prevent prolonged processes from inflating costs. The order also directs reconsideration of the linear no-threshold model and the “as low as reasonably achievable” radiation standard, urging adoption of determinate, science-based limits in consultation with DOE, DOD, and EPA. Additional reforms include streamlined compliance with the National Environmental Policy Act, expedited approval of DOE- and DOD-tested designs, high-volume licensing pathways for small modular and microreactors, longer license renewal periods, and restrictions on mid-construction design changes. Together, these measures are intended to increase the U.S. nuclear fleet from approximately 100 gigawatts today to 400 gigawatts by 2050.

Timeline of Executive Order 14300

The order establishes clear timelines for regulatory revision and implementation. Immediately upon issuance, the NRC is instructed to begin reorganization planning with the DOGE team, including staff adjustments and the establishment of a dedicated regulatory rewrite group. Within nine months (i.e., by February 2026), the NRC must issue notices of proposed rulemaking to begin the wholesale regulatory overhaul. Within eighteen months (i.e., by November 2026), the NRC is required to issue final rules and guidance to conclude the process. These reforms are not meant to be aspirational but binding: new licensing deadlines are to take effect once rules are finalized, and expedited licensing pathways are expected to operate continuously thereafter. Over the long term, the Administration set an expansion target of 400 gigawatts of nuclear capacity by 2050, with NRC reform identified as the necessary foundation for that growth.

The directives in EO 14300 build upon and, in some cases, go beyond the requirements Congress has already imposed through recent legislation.

The Nuclear Energy Innovation and Modernization Act (NEIMA), enacted in 2019, required the NRC to modernize its fee recovery and licensing processes. Among its provisions, NEIMA directed the Commission to develop performance metrics and milestone schedules to improve predictability in licensing. It also mandated greater reliance on risk-informed, performance-based regulation to accommodate advanced reactors. EO 14300 references this framework but criticizes the NRC for treating NEIMA’s milestone schedules as nonbinding guidance. In contrast, the order requires binding deadlines and fee caps to ensure accountability.

The Nuclear Energy Innovation Capabilities Act (NEICA) of 2017 focused on enhancing the Department of Energy’s capabilities to support advanced nuclear technologies. It directed DOE to establish new testing infrastructure, including the versatile test reactor, and to improve collaboration with the NRC in order to provide technical validation for licensing. EO 14300 leverages this foundation by establishing an expedited NRC pathway for reactor designs already validated through DOE or DOD testing programs, limiting NRC review to risks that are unique to new commercial applications.

Most recently, the Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy Act (ADVACNED), enacted in 2024, directly mandated that the NRC regulate in a manner that does not unduly restrict the civilian use of nuclear energy. It made explicit that the NRC’s mission includes facilitating deployment alongside its responsibility for safety. EO 14300 operationalizes this statutory mandate by embedding deployment facilitation into NRC’s culture, structure, and processes.

Executive Order 14300 may represent one of the most significant federal interventions in nuclear regulatory policy in decades. By restructuring the NRC’s mission, staff, and regulatory framework, the Administration intends to accelerate licensing timelines, reduce costs, and enable a fourfold expansion of U.S. nuclear capacity by mid-century. The order builds directly on NEIMA, NEICA, and the Advanced ACT, but moves further by mandating not just efficiency but a fundamental shift in regulatory philosophy. The practical implementation of these reforms, through the nine- and eighteen-month deadlines, through revised safety standards, and through new licensing pathways, will define whether the United States can regain global leadership in nuclear technology and deliver on its stated goals of energy security, economic growth, and climate resilience.
