Radiant has transported its 1 MWe Kaleidos microreactor from California to the Idaho National Laboratory for testing at the DOME facility. The unit will undergo a five-phase development program, including a 150-hour continuous run, to validate performance data for NRC licensing. This testing supports the company's goal to deliver a commercial microreactor to Buckley Space Force Base by 2028.

QuoteRadiant's 1 MWe microreactor - which is designed to be transportable - is making the journey from California to the DOME test bed at Idaho National Laboratory on the back of a truck. ;

"We said we'd make a microreactor that is transportable by land, sea and air. We did. Kaleidos is traveling more than 1,000 miles on a trailer bed," the company said.

Radiant's reactor was selected last year to undergo testing at the DOME (for Demonstration of Microreactor Experiments) test bed, where the repurposed containment structure of a former experimental breeder reactor provides a safe environment to test experimental reactor concepts and gather performance data.
