President Trump’s executive orders have jolted the U.S. nuclear sector. One year on, concrete funding, regulatory reforms and fresh commercial applications show momentum building fast. Billions in federal support now back specific projects. Timelines once measured in decades have compressed. And the focus has expanded beyond power plants to data centers, manufacturing and even oceangoing vessels.
Short timelines. High stakes. The administration set an ambitious goal: quadruple domestic nuclear capacity to 400 gigawatts by 2050. Early results appear in the form of $800 million awarded late last year to the Tennessee Valley Authority and Holtec Government Services for initial deployments of advanced light-water small modular reactors. A further $94 million went in May 2026 to eight American companies to close supply-chain gaps and prepare sites. These steps follow a March 2025 solicitation aimed at de-risking Gen III+ designs.
U.S. Energy Secretary Chris Wright captured the policy thrust in a statement released with the latest awards. “President Trump has made clear that America is going to build more energy, not less, and nuclear is central to that mission,” Wright said. “Advanced light-water SMRs will give our nation the reliable, round-the-clock power we need to fuel the President’s manufacturing boom, support data centers and AI growth, and reinforce a stronger, more secure electric grid. These awards ensure we can deploy these reactors as soon as possible.” (Energy.gov, May 2026)
Projects are already taking shape. TVA and Holtec will advance work in Tennessee and Michigan. A separate $40 billion U.S.-Japan partnership announced in March 2026 targets deployment of GE Vernova Hitachi BWRX-300 reactors in Tennessee and Alabama, promising three gigawatts of firm power. NuScale Power secured NRC approval for an uprated design. The NRC itself has begun rolling out reforms to meet an 18-month licensing mandate from the White House.
But the story runs deeper than new plants on existing grids. Electricity demand is surging. Hyperscalers need constant, carbon-free power. Tech giants have responded with direct investments. Meta, Amazon and Google have backed projects with TerraPower, Oklo, X-energy and Kairos Power. Some deals aim for gigawatts online by the early 2030s. Co-location of reactors with data centers has moved from concept to active discussion.
The pace feels different this time. Past nuclear builds suffered from regulatory delays, ballooning costs and first-of-a-kind risks. Trump’s orders directed the Department of Energy to stand up pilot reactors outside national labs. The target: achieve criticality in at least three reactors by July 4, 2026. The Pentagon received parallel instructions to field its own pilot within three years. Private developers welcomed the signal. James Walker, CEO of Nano Nuclear Energy, called the moves “a much-needed catalyst” that circumvents long-standing bottlenecks and creates initial customers. (Reuters, July 2025)
Supply chains remain a constraint. Some designs rely on high-assay low-enriched uranium, which lacks domestic production at scale. Others pursue low-enriched uranium plus fuel that can draw on existing facilities. The recent awards target exactly these gaps: forging capacity, fuel fabrication and site preparation. Eight recipients include Constellation, Nebraska Public Power District, BWXT and smaller specialists. Their work aims to make volume deployment realistic in the 2030s rather than the 2040s.
Yet the most striking recent development lies offshore. On May 7, 2026, Transportation Secretary Sean Duffy and the Maritime Administration launched an initiative to explore small modular reactors for commercial shipping. MARAD issued a formal request for information seeking industry views on nuclear-powered cargo vessels, ports and logistics networks. The agency warned that global competitors are already integrating nuclear propulsion. Russia operates a fleet of nuclear icebreakers. Without domestic action, the U.S. risks falling behind in maritime competitiveness, fuel costs and supply-chain resilience.
MARAD emphasized treating nuclear propulsion as commercial infrastructure rather than a technology demonstration. It wants concepts that let ships travel farther on less fuel and maintenance while supporting military logistics as a secondary benefit. The World Nuclear Association has documented years of conceptual work on nuclear merchant ships, but few have reached commercial reality. This RFI marks an official U.S. step toward changing that.

Industry reaction mixes optimism with realism. Patrick O’Brien of Holtec noted the orders could speed near-term deployment of proven technologies even if exotic designs face steeper hurdles. Building an entire advanced reactor system inside one year remains “extremely difficult” given current supply chains. Still, the combination of federal funding, shortened licensing and private capital from tech companies has shifted expectations. Analysts now speak of first U.S. SMRs operating late this decade rather than in the 2030s.
Regulatory modernization continues. The NRC has advanced Part 53, a technology-neutral, risk-informed framework. Additional reforms aim to handle large numbers of microreactors and modular units through standardized applications. These changes respond to decades of complaints that licensing timelines and costs killed projects before they left the drawing board.
International dimensions have grown too. The U.S.-Japan energy pact illustrates how Washington seeks allies to counter Russian and Chinese nuclear exports. TerraPower, backed by Bill Gates, gained construction approval in Wyoming for a sodium-cooled reactor that will use more-enriched fuel; operations are eyed for the early 2030s. X-energy has secured milestones on its TRISO fuel and signed a major deal in the United Kingdom.
Challenges persist. Waste disposal talks continue with states. Workforce shortages loom. First-of-a-kind cost estimates still make investors nervous despite government cost-sharing. But the policy direction is unmistakable. Federal dollars, executive mandates and private demand have aligned. Power-hungry factories and AI facilities cannot wait for perfect solutions. They need reliable electrons now.
So the SMR push broadens. From Tennessee riverbanks to Michigan sites to potential shipyards on the coasts. Each new award and regulatory tweak chips away at the old barriers. The question is no longer whether the technology will be built in the United States. It is how quickly the first gigawatts reach the grid, the factories and, perhaps soon, the open sea.
