The Department of Energy is betting that the biggest obstacle to next-generation nuclear power is no longer the science. It's everything that comes after: finding land, building supply chains, navigating regulators, and turning a working prototype into something you can actually sell. A new federal initiative called Launch Pad is designed to clear that path.

Introduced in March, Launch Pad offers nuclear developers access to 2,000 acres on the Idaho National Laboratory federal site, flexible contracts with the Department of Energy, and direct help securing licenses from the Nuclear Regulatory Commission. The Idaho National Laboratory has more than 75 years of reactor testing experience, which means developers aren't building on empty land. They're plugging into existing infrastructure, expertise, and credibility.

Why this matters beyond the lab

Advanced reactors, particularly small modular and micro-scale designs, have been technically promising for years. The gap has always been commercial. Building the first of anything is brutally expensive and legally complicated. Every new reactor design requires fresh regulatory approval, and the licensing process alone can swallow years and hundreds of millions of dollars before a single kilowatt is produced.

Federal support "can help significantly de-risk first-of-a-kind nuclear technology," Rita Baranwal, Chief Nuclear Officer at Radiant Industries, told Reuters Events. Radiant was recently selected for Launch Pad and will be the first developer to test at the Idaho lab's DOME facility, which is designed to safely test reactors up to 20 megawatts of thermal capacity. Radiant is also building its first Kaleidos reactors at a new factory in Oak Ridge, Tennessee, with Launch Pad providing the authorization to build, fuel, and test there.

Three other companies were selected in May: NuCube Energy, which is developing a 15-megawatt high-temperature microreactor alongside Idaho State University; Deployable Energy, building a 1-megawatt gas-cooled microreactor; and General Matter, which aims to build domestic uranium enrichment capacity. That last piece matters as much as the reactors themselves. A reactor that depends on foreign uranium supply is a vulnerability, not an asset.

The stage these companies are actually at

Launch Pad has two pathways. One covers projects physically located at the Idaho lab; the other, called Launch Pad USA, supports projects elsewhere but operating under Department of Energy authorization. Companies can apply to both at once.

A spokesperson for Terrestrial Energy, which is participating in an earlier federal pilot program, put the challenge clearly: the primary problem is no longer basic scientific research. It's engineering maturation, fuel availability, supply chain readiness, licensing, and then commercial deployment. Government programs that coordinate those activities can surface problems earlier, before they become expensive or fatal to a project.

Not every developer sees Launch Pad as the right vehicle. Oklo, which is enrolled in two earlier pilot programs, told Reuters Events it is focused on executing those projects and using "the regulatory pathway that best fits each project." Different reactor designs, at different stages, need different paths. That's not a criticism of Launch Pad so much as a sign that the field is diverse enough to support multiple approaches.

The National Reactor Innovation Center at the Idaho lab will select additional Launch Pad applicants later this year and review future applications annually.

Launch Pad builds on the Reactor Pilot Program that President Trump introduced in May 2025, which aimed to get at least three small modular test reactors to the point of a self-sustaining chain reaction by July 4, 2026. Eleven projects were accepted into that program; nine into a related fuel supply chain initiative. All of those companies are eligible to apply for Launch Pad.

The cumulative picture is a federal infrastructure being assembled, piece by piece, around a technology the government has decided it needs. Whether that technology arrives in time to matter for the electricity grid depends on whether the engineering and the policy keep moving together.
