NRIC Launch Pad Selects Four Startups

Key Takeaways

• DOE offers INL sandbox, but firms must fund their own R&D.
• Deployable Energy seeks $25 M seed to build 1 MWe “Nuclear Battery.”
• Radiant Industries secured >$300 M to scale 1.2 MWe HTGR.
• NuCube partners with Energy Vault to integrate microreactor with battery storage.

Pulse Analysis

The Department of Energy’s National Reactor Innovation Center (NRIC) at Idaho National Laboratory has opened its first Nuclear Energy Launch Pad, a government‑sponsored sandbox that gives private developers access to 2,000 acres of test land, utilities, and specialist expertise. While the program does not provide direct cash, it removes a major barrier—facility access—allowing firms to accelerate prototype testing and regulatory engagement. The move aligns with the Biden administration’s push to diversify the nation’s clean‑energy portfolio, recognizing micro‑reactors as a fast‑track source of low‑carbon baseload power for industrial, remote, and defense applications.

The four chosen companies illustrate the breadth of the emerging micro‑reactor ecosystem. Deployable Energy, a Houston startup, is raising a $25 million seed round to field a 1 MWe helium‑cooled “Nuclear Battery” by 2028, targeting oil‑and‑gas process heat. General Matter focuses on re‑enriching depleted uranium at Paducah, aiming for commercial enrichment by decade’s end. NuCube Energy, in partnership with Energy Vault, plans a 4 MWt TRISO‑fuel reactor that feeds a proprietary battery‑management system, backed by a $13 million financing. Radiant Industries, fresh from a $300 million funding round, will test its 1.2 MWe HTGR in INL’s DOME facility, positioning the design for diesel‑generator replacement.

By clustering these innovators at a single national laboratory, the Launch Pad could create a de‑facto supply chain for advanced nuclear components, hastening certification and lowering costs. The sandbox model also signals to investors that the federal government is willing to de‑risk early‑stage projects, which may unlock additional private capital and future DOE grant programs such as ARPA‑E’s $50 million transuranic‑fuel effort. If the selected firms meet their milestones, the United States could see commercial micro‑reactors in service within five years, reshaping the energy mix for remote sites, grid‑hardening, and carbon‑free industrial heat.
