The Department of Energy announced in May 2026 that eight companies will split more than $94 million in new federal funding to advance the licensing, design, and manufacturing of small modular nuclear reactors across the United States. The awards, issued under the Generation III+ Small Modular Reactor Pathway to Deployment Program, mark the second phase of a $900 million initiative that has already committed up to $800 million to two lead projects. It is the largest federal investment in light-water SMR technology ever, arriving at a moment when electricity demand is surging, driven by the explosive growth of AI data centers, widespread electrification, and a fleet of large legacy reactors approaching the end of their operating lives.
Where the money is going
The $94 million falls under the program’s Tier 2 track, which was created to fund a broader set of pre-construction activities: Early Site Permit applications at the Nuclear Regulatory Commission, reactor component manufacturing, fuel fabrication, and detailed engineering work. The total Tier 2 allocation is approximately $100 million, according to the DOE’s official program overview. The funding announcement confirmed all eight recipients.
Among them, BWX Technologies disclosed the most detail. The company’s fiscal year 2025 SEC filing reports a $21.42 million award supporting nuclear fuel and component manufacturing at its facility in Mount Vernon, Indiana. Constellation is pursuing an Early Site Permit in New York, where it already operates the Nine Mile Point nuclear station. Nebraska Public Power District is doing the same in Nebraska. Other recipients span reactor design, supply chain development, and site characterization work.
The two Tier 1 recipients, announced earlier, are the Tennessee Valley Authority and Holtec International, each eligible for up to $400 million. TVA holds an NRC-issued Early Site Permit for its Clinch River site in Tennessee and is pursuing a construction permit there. Holtec is advancing its own SMR design at a separate location. Together, the Tier 1 and Tier 2 tracks bring the combined program budget to $900 million, authorized under the Consolidated Appropriations Act and administered through the DOE’s Office of Clean Energy Demonstrations.
Why this round matters now
The timing is not accidental. U.S. electricity demand, which was essentially flat for nearly two decades, has begun climbing sharply. Data center construction tied to artificial intelligence workloads is a primary driver. Utilities in Virginia, Texas, Georgia, and other states have revised their load forecasts upward by tens of gigawatts over the next decade. At the same time, a significant share of the country’s existing large nuclear fleet, which still generates roughly 19% of U.S. electricity, will reach the end of its licensed operating life in the 2030s and 2040s. Replacing that carbon-free baseload capacity is a problem that wind and solar alone cannot solve without massive storage buildouts.
Small modular reactors are designed to fill that gap. Their smaller output (typically 50 to 300 megawatts per unit, compared with 1,000-plus for a conventional reactor) is supposed to make them faster to build, easier to finance, and more flexible to site. Factory fabrication of major components could, in theory, cut construction timelines and reduce the cost overruns that have plagued large reactor projects like Vogtle Units 3 and 4 in Georgia, which came in years late and billions over budget.
But the SMR industry also carries recent scars. In 2023, NuScale Power and the Utah Associated Municipal Power Systems canceled the Carbon Free Power Project in Idaho, the most advanced SMR effort in the country at the time, after cost estimates ballooned and participating utilities pulled out. That failure raised pointed questions about whether SMRs could actually deliver on their economic promises. The current DOE program is, in part, an attempt to answer those questions by funding multiple companies and designs simultaneously rather than betting on a single project.
What the awards do and do not authorize
A critical distinction runs through the entire program: none of this money authorizes construction. The Tier 2 awards use milestone-based Other Transaction Agreements, a contracting mechanism that ties federal payments to specific technical and regulatory progress rather than open-ended cost reimbursement. If a company misses a milestone, the DOE can withhold further payments.
For the utilities pursuing Early Site Permits, the scope is even more narrowly defined. An NRC Early Site Permit confirms that a location is suitable for a nuclear plant and banks that approval for up to 20 years, but a separate combined construction and operating license must be obtained before any concrete is poured. That distinction, documented in the NRC’s own reactor licensing guidance, means the Constellation and Nebraska Public Power District awards fund site evaluation, not building.
Construction authorization, fuel loading, and grid connection remain years away and will each require separate regulatory approvals and substantial additional private capital.
What we still do not know
Several significant gaps in the public record make it difficult to judge how quickly these awards will translate into operating reactors.
The DOE has not disclosed the specific milestone schedules or performance metrics embedded in each Tier 2 agreement. Without those benchmarks, outside observers, state regulators, investors, and communities near proposed sites cannot track whether a company is on pace or falling behind, or whether delays will trigger reductions in federal payments. Accountability is built into the contract structure, but only works if the milestones are visible.
No primary DOE or NRC records detail projected dates for first fuel loading, commercial operation, or grid interconnection for any of the eight awardees. The absence of public timelines is notable for a program framed around accelerating deployment.
Company-specific cost-share amounts also remain undisclosed. Federal energy awards typically require private matching funds, and the ratio of federal to private dollars shapes how much financial risk the government is absorbing versus the companies themselves. BWXT’s 10-K confirms its $21.42 million award but does not specify its cost-share obligation, and filings from other recipients offer even less detail.
There is also an open question about technology selection. Some of the utilities receiving Tier 2 funding are still evaluating multiple SMR designs and may not settle on a single vendor until later in the decade. Site characterization and early engineering work funded now could benefit whichever design is ultimately chosen, but they do not guarantee that any particular SMR project will advance to construction.
What to watch next
For anyone trying to gauge whether these reactors will actually get built, the documents that matter most have not been filed yet. NRC docket submissions from Constellation and Nebraska Public Power District will show whether Early Site Permit reviews move faster than the multi-year timelines that characterized previous large-reactor applications. Future milestone reports from BWXT and other Tier 2 recipients will reveal whether component manufacturing and fuel fabrication are hitting their targets. Updated cost-share disclosures in annual SEC filings will clarify how much private capital is flowing alongside federal dollars.
The political environment, at least, is favorable. The bipartisan ADVANCE Act, signed into law in 2024, streamlined parts of the NRC’s licensing process and directed the commission to develop a more efficient framework for advanced reactor reviews. Multiple states have passed or are considering legislation to enable SMR siting. And both parties in Congress have signaled continued support for nuclear energy as a tool for grid reliability and decarbonization.
But favorable politics and federal seed money have not been enough before. The DOE’s earlier SMR Licensing Technical Support program, launched in 2012 with roughly $452 million, helped NuScale achieve the first-ever NRC design certification for an SMR, yet the flagship project that was supposed to use that design still collapsed. The current $900 million program is larger, more diversified, and structured with tighter milestone accountability. Whether that is enough to break the pattern remains the central question for the industry, and the answer will not come from Washington. It will come from NRC dockets, factory floors, and utility boardrooms over the next several years.
