Radiant wins DOE approval of safety analysis for Kaleidos microreactor, enabling full-power testing

The U.S. Department of Energy has approved Radiant's Documented Safety Analysis for its Kaleidos microreactor, which the company says makes it the only microreactor reviewed and approved by the DOE for full power operations. The approval covers not just criticality but full power, full temperature testing at Idaho National Laboratory. Radiant will test the complete reactor system using the same design intended for manufacturing at scale. The company says the next step toward commercialization is a Readiness Review.
