Radiant

Radiant Nuclear is reinventing power with portable, zero-emission microreactors. Its Kaleidos units pack a full nuclear reactor into a shipping container—ready to replace dirty diesel wherever reliable electricity is needed. Run safely on helium-cooled, meltdown-proof TRISO fuel, these reactors deliver clean heat and power for five years straight—with factory-refueled service for 20-year lifespans. Selected by the U.S. Department of Energy for groundbreaking testing at Idaho National Lab and already under contract to deploy with the U.S. Air Force, Radiant is making truly resilient, on-demand energy a reality.
