The U.S. Department of Energy announced in May 2026 that it had selected eight companies to share more than $94 million in federal funding aimed at one stubborn problem: the licensing delays and supply-chain gaps that keep small modular reactors stuck on paper instead of under construction. The grants, awarded under DOE’s Generation III+ SMR Pathway to Deployment Program, are designed to pull a second wave of reactor developers through the same regulatory and industrial chokepoints that have slowed even the most advanced projects in the country.
The recipients include utilities and reactor developers that have signaled serious intent to build but have not yet filed formal license applications with the Nuclear Regulatory Commission. Under DOE’s cost-sharing rules, each company must put up a significant share of its own capital alongside the federal dollars, a requirement meant to weed out proposals that lack real financial commitment.
Where the $94 million fits in a $900 million bet on SMRs
The eight awards fall under what DOE calls Tier 2: Fast Follower Deployment Support. They are part of a broader $900 million solicitation that also includes two much larger Tier 1 grants, each worth $400 million, directed at first-of-a-kind reactor projects. The Tennessee Valley Authority received its Tier 1 award for a reactor at the Clinch River site in eastern Tennessee, a location that already holds an NRC early site permit from a previous nuclear effort. Holtec International received the other Tier 1 award for its project at the Palisades facility in Michigan, where the company has been working to restart a shuttered conventional reactor alongside new SMR plans.
Tier 2 operates on a different logic. Instead of bankrolling a single demonstration plant, it spreads federal money across licensing preparation, supplier qualification, and site readiness for multiple developers at once. The reasoning is practical: if only one or two companies ever reach the construction phase, domestic manufacturers will not have enough orders to justify the tooling, workforce training, and nuclear-grade quality certifications that reactor components demand. Eight simultaneous projects create a stronger demand signal.
That signal matters more now than it would have a few years ago. After NuScale Power and the Utah Associated Municipal Power Systems canceled their Carbon Free Power Project in late 2023, citing rising costs and insufficient subscriber commitments, the SMR sector lost its most visible near-term demonstration. The cancellation raised pointed questions about whether any SMR design could survive the gap between engineering promise and commercial reality. DOE’s tiered funding structure is, in part, an answer to that question: spread the risk, back more horses, and keep the supply chain warm while the front-runners work through NRC review.
Why utilities are suddenly interested
The timing of these awards tracks with a sharp increase in electricity demand that has caught grid planners off guard. Data center construction, driven largely by the expansion of artificial intelligence workloads, has pushed utilities across the Southeast, Mid-Atlantic, and Midwest to project load growth rates not seen in two decades. Dominion Energy, Duke Energy, and other large utilities have publicly stated that they are evaluating new nuclear capacity as one of the few options that can deliver large blocks of carbon-free, always-on power without the land footprint of wind and solar farms.
Small modular reactors appeal to these utilities for a specific reason: their output, typically between 50 and 300 megawatts per unit, can be matched to the size of a single data center campus or industrial facility. That modularity, at least in theory, allows a utility to add capacity in increments rather than committing to a single multi-billion-dollar conventional plant. The catch has always been that no SMR design has yet completed NRC licensing and construction in the United States, so every project still carries first-of-a-kind risk even if the underlying technology is based on well-understood light-water reactor principles.
The Generation III+ label in the program’s name is a deliberate scope choice. It limits eligibility to reactor designs that use proven light-water technology with updated safety features, rather than the more experimental advanced reactors (molten salt, high-temperature gas, sodium-cooled) that other DOE programs support. The intent is speed: Gen III+ designs face a shorter path through NRC review because they build on decades of operating experience and an existing regulatory framework.
What the money actually pays for
DOE has described, at a high level, the categories of work that Tier 2 funds are meant to support. These include detailed site characterization studies and environmental analyses that utilities need before committing to a specific reactor design; engineering work to bring reactor blueprints to the level of detail that NRC requires for a formal application; grid-integration planning that maps how a new reactor would connect to existing transmission infrastructure; and supplier qualification efforts that help component manufacturers meet nuclear-grade quality standards.
What DOE has not published is a line-item breakdown for each of the eight companies. The agency’s announcement does not specify how much each recipient will receive, what share of each award goes to licensing versus supply-chain work, or which companies are closest to filing formal NRC applications. That opacity makes it difficult to assess which projects are on a near-term construction track and which are still in early planning.
Supply-chain details are even harder to pin down. DOE has emphasized the goal of building order books that give manufacturers confidence to invest in nuclear-qualified production lines, but the names of specific vendors, the components they are being asked to produce, and the timelines for qualification testing have not been disclosed. For an industry that has not built a new reactor from scratch in the United States in decades, rebuilding that supplier base is arguably the hardest part of the entire effort.
The regulatory bottleneck that funding alone cannot fix
Money helps, but the NRC’s review process operates on its own clock. The commission’s public docket system tracks every new reactor project from pre-application meetings through design certification, combined operating licenses, and construction permits. As of mid-2026, several SMR designs are in various stages of NRC engagement, but none of the Tier 2 recipients have yet appeared in the docket with formal license applications tied to this funding round.
That gap between receiving a DOE award and filing with the NRC is where many nuclear projects have historically stalled. Preparing a license application is itself a multi-year, multi-hundred-million-dollar effort that requires finalized engineering designs, site-specific safety analyses, and environmental impact statements. The Tier 2 grants are sized to help companies get through that preparatory phase, not to fund construction. Whether the eight recipients can convert planning money into filed applications within the next two to three years will be the first real test of the program’s effectiveness.
Observers tracking the program’s progress will find the most reliable signals not in DOE press releases but in NRC’s administrative records: formal docket entries, accepted applications, and review schedules. Those filings, when they appear, will show whether the $94 million accelerated real regulatory work or simply funded another round of studies.
What $94 million can and cannot buy
Placed against the full cost of building a nuclear power plant, $94 million split eight ways is modest. A single SMR unit is expected to cost between $3 billion and $5 billion to build, depending on the design and site, and licensing alone can run into the hundreds of millions. The Tier 2 grants are not construction money. They are bridge funding meant to keep projects moving through the expensive, unglamorous middle phase between concept and groundbreaking.
The cost-sharing requirement adds leverage. Because each company must match or exceed DOE’s contribution with private capital, the $94 million in federal funds should pull significantly more private spending into design work, licensing, and early site activities. DOE has not disclosed the total private commitments attached to these awards, so the full scale of investment remains unclear. For policymakers and communities near prospective sites, those numbers will matter as much as the federal headline figure.
What is clear is that DOE has built a structured pipeline: large grants for the two lead projects, smaller grants for eight followers, and a regulatory and industrial support framework meant to keep the entire cohort moving forward. The open question is whether that pipeline produces licensed, buildable reactors or whether it becomes another chapter in the long history of nuclear projects that looked promising on paper and never broke ground.
