Radiant wins largest slice of US Army's $2.2B Janus microreactor programme

Radiant Industries has secured the largest award under the US Army's Janus Program, a set of contracts worth up to $2.2 billion combined that will see five companies build and operate nuclear microreactors at military installations across the United States.

Radiant disclosed an agreement worth up to $750 million to deploy 15 factory-built, 1-megawatt Kaleidos microreactors by 2030, beginning with a three-unit installation at Fort Benning, Georgia. The Army named four other vendors alongside Radiant: Westinghouse Government Services (eVinci reactor, Fort Drum, New York), Antares Nuclear (Fort Bragg, North Carolina), BWXT Advanced Technologies (Fort Campbell, Kentucky) and General Atomics Electromagnetic Systems (Fort Hood, Texas).

Run in partnership with the Department of War Innovation Unit, the Janus Program is intended to move advanced microreactor technology beyond test programmes and into sustained operation at defence bases. The planned reactors will each generate under 20 megawatts and occupy less than five acres, providing resilient, long-duration power to installations.
