The U.S. Navy chose Radiant on Oct. 20 to supply a planned nuclear microreactor for an Indiana base, seeking to protect critical operations from commercial grid outages.
Radiant announced the selection for Naval Weapons Station Crane. The proposed reactor would provide electricity independently of the commercial grid, but it has not begun supplying power at the base.
The decision identifies a supplier for a project the Department of War announced in September. The department said the reactor would be commercially owned and operated and, if installed, would be Indiana’s first nuclear reactor to produce power.
Vice Adm. Brad Collins, who heads Navy Installations Command, said stronger power resilience at Navy sites supports fleet operations.
Radiant rates its factory-built Kaleidos design at 1 megawatt of electrical output. The company says the unit can travel by aircraft, ship or overland and does not need cooling water or extensive construction at the site. It projects a 20-year service life, with up to five years between refuelings.
Radiant says Kaleidos is undergoing testing at Idaho National Laboratory’s Demonstration of Microreactor Experiments facility. Those tests are intended to show how the reactor performs and whether it operates reliably.
Radiant says further design work and prototype testing remain before deployment at Crane. The project also requires environmental review, site preparation and coordination with regulators. The Department of War’s installation deadline is no later than September 2028.
