Radiant Industries announced on June 4 that the safety design strategy (SDS) for a test of its Kaleidos microreactor in the National Reactor Innovation Center’s DOME test bed at Idaho National Laboratory now has approval from the Department of Energy. Radiant hopes to test Kaleidos—a 1-MW high-temperature, gas-cooled reactor—by 2026 and then market portable commercial reactors to power remote locations and provide backup or primary power for critical applications in hospitals or for disaster relief.
