Radiant's Kaleidos Microreactor Headed to NSWC Crane in Martin County
The Navy picked Radiant Industries to install a 1-megawatt Kaleidos nuclear microreactor at Naval Weapons Station Crane, the first time the Navy has put an advanced reactor on a shore-based installation. The Department of War wants it running by September 2028 to protect Crane's microelectronics and weapons-testing work from grid disruption. Worth noting for anyone tracking the contract: this is not new federal money. The Crane installation sits inside the $750 million, 15-unit agreement the Army already signed with Radiant in August, so the dollar ceiling has not grown even though Radiant now has to satisfy both the Nuclear Regulatory Commission and the Navy's own nuclear propulsion program, a dual-review burden none of the other four reactor vendors building on military bases are carrying. Before any of this happens at Crane, Radiant still has to clear design work, licensing, and site prep, and the entire military microreactor program depends on a thin U.S. supply of the enriched fuel these reactors use, a bottleneck that could slow all five military sites at once, not just this one.
- Impact
- This isn't new money: the Navy's own release counts Crane within Radiant's existing $750 million, 15-unit Army agreement, meaning the contractual ceiling hasn't grown even though Radiant now answers to both the NRC and the Naval Nuclear Propulsion Program, a dual-regulator burden none of its four Janus rivals (Antares, BWXT, General Atomics, Westinghouse) carry at their sites. Radiant is now the only vendor holding contracts across Army, Navy and Air Force, but the entire program rides on a HALEU fuel supply chain where U.S. enrichment capacity (Centrus's Piketon cascade, ~6 MTU/year) and Urenco's UK facility (not online until 2031) could bottleneck all five Janus deployments at once.
- Watch
- Watch for NRC licensing filings and site-prep contract solicitations at Crane, expected to ramp 12-18 months ahead of the September 2028 deadline, alongside progress at Radiant's Idaho National Laboratory DOME prototype testing.
- For the huddle
Should our skilled-trades and environmental-consulting capacity be positioning now to bid on NRC licensing and site-prep work at Crane, given the solicitation window is expected to open well before the 2028 deadline?
Not yet. The only milestone that matters is whether the unnamed partner issues a purchase order by Nov. 15, 2026, and until that happens, the letter of intent is a corporate announcement, not a construction commitment.
