Trump Orders Overhaul of Nuclear Regulation to Accelerate Reactor Deployment
In a significant move aimed at revitalizing the U.S. nuclear power industry, President Donald Trump signed a series of executive orders on Friday, May 23, 2025, targeting a comprehensive overhaul of the Nuclear Regulatory Commission (NRC) and seeking to dramatically accelerate the deployment of new nuclear reactors across the nation. The directives signal a strong push from the administration to remove perceived regulatory hurdles and leverage nuclear energy as a key component of the country's future energy landscape, particularly in meeting the burgeoning power demands of advanced technologies like artificial intelligence.
The Nuclear Regulatory Commission, an independent agency established in 1974, is tasked with regulating the nation's civilian use of nuclear materials, primarily ensuring the safety and security of nuclear power plants and other nuclear facilities. For decades, the agency's rigorous licensing and oversight processes have been central to maintaining safety standards, but they have also been criticized by the industry for being excessively slow, complex, and costly, contributing to the challenges faced by new nuclear construction projects in the U.S.
A senior White House official, briefing reporters on the executive actions, described the orders as calling for a "total and complete reform" of the 50-year-old regulatory body. A central mandate of the new directives is the imposition of an 18-month deadline for the NRC to make decisions on nuclear reactor license applications. This timeline represents a stark contrast to the multi-year, often decade-long, processes that have historically characterized nuclear plant licensing in the United States.
President Trump emphasized that while the orders focus on facilitating the deployment of small, advanced reactors — widely seen by many in the industry as the future due to their potential for modular construction, lower costs, and enhanced safety features — the administration's support extends to large-scale plants as well. "We're also talking about the big plants — the very, very big, the biggest," Trump stated during the signing ceremony. "We're going to be doing them also."
The signing ceremony was attended by several nuclear industry executives, including Joe Dominguez, the CEO of Constellation, the largest operator of nuclear power plants in the U.S. Dominguez voiced a common industry grievance, stating that regulatory delay has been the single biggest impediment to nuclear development. "We're wasting too much time on permitting and we're answering silly questions, not the important ones," he remarked, highlighting the industry's frustration with the current regulatory environment. Following reports of the impending executive orders, nuclear stocks saw a rally on Friday, reflecting investor optimism about the potential impact of these policy changes.
Overhauling the Nuclear Regulatory Commission
The core of the executive orders lies in the mandated overhaul of the NRC. While the orders do not remove or replace any of the five sitting commissioners who lead the agency, they call for a substantial reorganization. When pressed on whether the changes would lead to staff reductions at the commission, the senior White House official indicated that while a total reduction in staff was undetermined, there would likely be "turnover and changes in roles."
Any significant reduction or reorganization of NRC staff comes at a critical juncture for the agency. The commission is currently facing a heavy workload, including the complex and unprecedented task of reviewing applications to potentially restart operations at two previously mothballed nuclear plants: Palisades in Michigan and Unit 1 at Three Mile Island in Pennsylvania. The process of bringing retired reactors back online presents unique regulatory challenges, requiring thorough safety reviews and assessments of aging infrastructure, a process that adds to the agency's existing responsibilities related to operating reactors, new license applications, and decommissioning.
The industry argues that the current regulatory framework, designed primarily for large, light-water reactors built decades ago, is ill-suited for the review of advanced reactor designs, particularly small modular reactors (SMRs). These newer designs often incorporate passive safety features and are intended for factory fabrication and modular assembly, potentially reducing construction time and cost. However, licensing these novel designs requires the NRC to develop new review processes and standards, a task that has been ongoing but is perceived by the industry as moving too slowly.
The 18-month deadline for license decisions is arguably the most impactful aspect of the NRC overhaul. This aggressive timeline aims to force a streamlining of the review process, potentially requiring significant changes in how the NRC operates, allocates resources, and interacts with applicants. Critics may raise concerns about whether such a compressed schedule could compromise the thoroughness of safety reviews, while proponents will argue it is necessary to make nuclear power a viable and competitive option for future energy needs.
Accelerating Deployment on Federal Land and Beyond
Beyond the direct overhaul of the NRC's licensing timeline, the executive orders also create a new regulatory framework specifically for the deployment of nuclear reactors on federal land. This framework allows the Departments of Energy (DOE) and Defense (DOD) to build reactors under their own authorities, bypassing the standard NRC commercial licensing process for projects deemed necessary for national security purposes or critical federal facilities. The senior administration official highlighted that this provision would enable the use of safe and reliable nuclear energy to power and operate critical defense facilities and, notably, AI data centers located on federal property.
The inclusion of AI data centers underscores a significant shift in the drivers for nuclear power. For years, the industry struggled economically, leading to the shutdown of a dozen reactors as they found it difficult to compete with cheap and abundant natural gas. Building new large plants proved notoriously slow and expensive, exemplified by the Plant Vogtle expansion in Georgia, where two new reactors came online seven years late and $18 billion over budget.
However, the explosive growth of artificial intelligence and the corresponding need for massive computing power have created an unprecedented demand for electricity. AI data centers consume vast amounts of energy, and their power needs are projected to grow exponentially. This has led major technology companies to look for reliable, clean, and high-density power sources, with nuclear energy emerging as a compelling option. The ability to site reactors on federal land, potentially closer to where these energy-hungry facilities might be located or connected to the grid, could significantly reduce transmission challenges and speed up deployment compared to navigating state and local permitting processes for commercial sites.
The distinction between reactors built under DOE/DOD authority on federal land and those requiring NRC licenses for commercial operation is crucial. While the former would operate under federal agency oversight tailored to specific mission requirements, the latter would still fall under the reformed NRC's purview, albeit with the new 18-month decision deadline. This dual-track approach suggests an effort to leverage federal control for strategic deployments while attempting to improve the commercial pathway.
The potential for nuclear power to fuel the AI revolution is gaining traction. Constellation's plan to restart Unit 1 at Three Mile Island, for example, is reportedly backed by financial support from Microsoft, indicating direct investment from tech giants in nuclear assets to secure future power supply. Similarly, companies like Alphabet and Amazon are reportedly exploring or investing in small, advanced reactor technologies, seeing them as a potential solution for powering their future data center infrastructure. This corporate demand is injecting new capital and urgency into the nuclear sector.
Boosting Domestic Uranium and Fuel Cycle Capacity
Recognizing the strategic importance of the nuclear fuel supply chain, the executive orders also aim to revitalize domestic uranium mining and expand U.S. uranium enrichment capacity. The United States currently relies heavily on foreign sources, including Russia, for enriched uranium fuel needed to power its existing reactor fleet. This dependence has become a point of concern regarding energy security and geopolitical vulnerability.
Boosting domestic mining would reduce reliance on imports of raw uranium ore. Expanding enrichment capacity — the process of increasing the concentration of the fissile isotope U-235 — is even more critical, as it is a complex and capital-intensive step in the fuel cycle. The orders signal an intent to use federal policy and potentially financial incentives to rebuild this critical infrastructure within the U.S., ensuring a secure domestic supply chain for both existing reactors and the anticipated new deployments.
Furthermore, the orders aim to speed up reactor testing at the Department of Energy's national laboratories. These laboratories play a crucial role in researching, developing, and testing advanced reactor designs and fuel types. Accelerating this testing process can help bring new technologies closer to commercial readiness and provide essential data for the NRC's licensing reviews.
Historical Context and Future Challenges
The push to accelerate nuclear deployment comes after a long period of stagnation and decline for the U.S. nuclear industry. Following the accidents at Three Mile Island (Unit 2 partial meltdown in 1979) and Chernobyl (1986), public perception and regulatory scrutiny intensified. Combined with the rising costs of construction, lengthy licensing processes, and increasing competition from cheaper fossil fuels (particularly natural gas from the shale revolution) and later, renewables, new plant construction ground to a halt for decades.
The recent closures of several reactors were primarily driven by economic factors, as they struggled to compete in wholesale electricity markets. However, growing concerns about climate change, the need for reliable baseload power sources that don't emit greenhouse gases, and the aforementioned demand from high-load facilities like data centers have created a new impetus for nuclear energy.
While the executive orders demonstrate a strong political will to support nuclear power, significant challenges remain. The NRC, despite the mandate for reform, must still ensure that safety remains the paramount concern. Streamlining processes without compromising safety standards will be a delicate balancing act. The industry, for its part, must prove it can build new reactors — especially the advanced SMR designs — on time and within budget, overcoming the historical issues that plagued projects like Vogtle.
Supply chain issues, workforce development, and securing the necessary private investment beyond the initial interest from tech companies will also be critical factors determining the success of this accelerated deployment strategy. Furthermore, the long-standing issue of managing and disposing of spent nuclear fuel remains unresolved at the federal level, posing a challenge that must eventually be addressed for a sustainable nuclear future.
Potential Impacts and Broader Implications
The executive orders could have far-reaching impacts on the U.S. energy landscape. A more efficient and predictable regulatory process could significantly lower the financial risk associated with building new nuclear plants, potentially unlocking private investment. Accelerating the deployment of SMRs could make nuclear power a viable option for a wider range of applications and locations, including industrial facilities, remote communities, and as replacements for retiring fossil fuel plants.
The focus on federal land deployment for defense and AI data centers highlights a strategic recognition of nuclear power's role in national security and economic competitiveness in the age of artificial intelligence. Ensuring reliable, high-capacity power for critical infrastructure is becoming increasingly important.
Boosting domestic uranium and enrichment capacity would enhance U.S. energy independence and reduce vulnerability to disruptions in the global nuclear fuel market. This is particularly relevant in the current geopolitical climate.
However, the success of these initiatives will depend on effective implementation and the ability of the NRC and the industry to adapt to the new directives while maintaining public confidence in the safety of nuclear technology. The tension between accelerating deployment and ensuring rigorous safety oversight is inherent in the proposed reforms.
The executive orders represent a decisive step by the Trump administration to actively promote nuclear power as a solution to energy security, climate goals (by providing carbon-free electricity), and the specific demands of the digital economy. Whether this push can overcome the historical hurdles and usher in a new era of nuclear expansion in the U.S. remains to be seen, but the intent to fundamentally alter the regulatory and deployment landscape is clear.
Industry and Expert Reactions
Initial reactions from the nuclear industry have been largely positive, echoing Joe Dominguez's sentiment that regulatory streamlining is essential. Industry groups have long advocated for more predictable and efficient licensing processes to reduce project risk and cost. They view the 18-month deadline as an ambitious but necessary target to make new nuclear builds competitive.
Experts and analysts, however, offer a more nuanced perspective. While acknowledging the potential benefits of regulatory reform, many point out the complexity of nuclear safety reviews. Ensuring public safety requires thorough analysis of complex engineering designs, site-specific environmental impacts, and security considerations. Rushing this process, even under a strict deadline, could raise concerns. The NRC staff, composed of highly specialized engineers and scientists, faces the challenge of adapting their detailed review procedures to a significantly compressed timeline without sacrificing quality.
The potential for staff reductions or significant reorganization at the NRC also raises questions about the agency's capacity to handle an increased volume of applications for both traditional and advanced reactors, alongside ongoing oversight responsibilities for the existing fleet and decommissioning activities. Maintaining sufficient expertise and institutional knowledge is crucial for effective regulation.
The provisions allowing DOE and DOD to build reactors on federal land under separate authorities are seen by some as a pragmatic approach to deploying nuclear power for specific federal needs, bypassing the complexities of the commercial licensing pathway. However, questions may arise regarding the level of independent safety oversight for these facilities compared to NRC-regulated plants.
The focus on domestic uranium mining and enrichment is generally viewed positively from an energy security standpoint, aligning with broader efforts to reduce reliance on foreign adversaries for critical resources. However, rebuilding this infrastructure will require significant investment and time.
Overall, the executive orders are seen as a strong signal of intent from the administration to prioritize nuclear energy. Their ultimate effectiveness will depend on the details of implementation, the ability of the NRC to adapt while maintaining its safety mission, and the nuclear industry's capacity to deliver projects efficiently under the new framework.
The Role of Advanced Reactors and SMRs
President Trump's specific mention of small, advanced reactors reflects the growing consensus that these technologies may offer a more viable path forward for nuclear expansion than traditional large-scale plants. SMRs are typically defined as reactors producing up to 300 MWe, designed with modularity in mind, allowing components to be fabricated in a factory and shipped to the site for assembly. This approach is expected to reduce construction times, lower costs, and improve quality control compared to building large, custom-designed plants on-site.
Advanced reactors encompass a broader category, including SMRs but also other designs that may use different coolants (like gas, liquid metal, or molten salt) or fuel types, often incorporating enhanced safety features and potentially offering higher efficiency or the ability to use spent fuel. The NRC is actively working on developing regulatory pathways for these advanced designs, but the process is complex due to their novelty.
The 18-month licensing deadline is particularly relevant for SMRs and advanced reactors. A predictable and relatively short licensing period is crucial for attracting the significant private investment needed to bring these first-of-a-kind designs to market. Developers need confidence that their technology, once proven safe, can be licensed and deployed within a reasonable timeframe to achieve a return on investment.
Several U.S. companies are actively developing SMR and advanced reactor designs, some of which are already undergoing pre-application reviews with the NRC. The executive orders are likely intended to provide a strong signal of federal support for these efforts and pressure the regulatory process to keep pace with technological development.
The potential applications for SMRs are diverse. Besides grid-scale electricity generation, they can be used for industrial process heat, desalination, or powering remote locations. Their smaller size and potentially lower capital cost make them more flexible than large reactors. The interest from data center operators is a prime example of a new, high-load application where SMRs could be particularly well-suited, providing dedicated, reliable, and carbon-free power sources.
Conclusion: A New Chapter for U.S. Nuclear?
President Trump's executive orders mark a significant policy intervention aimed at fundamentally reshaping the regulatory and operational landscape for nuclear power in the United States. By targeting the Nuclear Regulatory Commission for a comprehensive overhaul and setting aggressive timelines for licensing, the administration is signaling a clear intent to remove perceived barriers to deployment.
The emphasis on accelerating the licensing process, facilitating deployment on federal lands for strategic purposes like powering AI data centers, and boosting domestic fuel cycle capabilities reflects a multi-faceted approach to revitalizing the industry. This push is occurring at a time when new drivers, particularly the immense energy needs of artificial intelligence and the growing focus on decarbonization and energy security, are creating renewed interest in nuclear energy.
While the executive orders provide a strong political impetus, their success will ultimately hinge on effective implementation. The NRC must navigate the challenge of streamlining its processes under a tight deadline while upholding its critical mission of ensuring public health and safety. The nuclear industry must demonstrate its ability to deliver advanced reactor projects reliably and economically.
The coming months and years will reveal whether these executive actions can truly unlock a new era of nuclear power expansion in the U.S., transforming it from a struggling legacy industry into a dynamic source of clean, reliable energy for the 21st century economy, particularly as the demands of the digital age continue to escalate.
The path forward for U.S. nuclear power remains complex, involving technological innovation, significant capital investment, public acceptance, and navigating the intricate balance between regulation and acceleration. However, the executive orders represent a clear statement of intent to prioritize nuclear energy and address the regulatory challenges that have long constrained its growth.
The potential benefits — reliable, carbon-free power, energy security, and fueling the growth of energy-intensive technologies like AI — are substantial. The challenges — ensuring safety, managing costs, and resolving waste issues — are equally significant. The success of this ambitious push will depend on the ability of all stakeholders to work within the new framework to realize the potential of nuclear energy while maintaining the highest standards of safety and security.
