Radiant secures over $300 million in Series D funding to advance its development of portable nuclear reactors, aiming to revolutionize energy access in underserved areas.

Target Information

Radiant, a company specializing in the development of portable nuclear reactors, has successfully raised over $300 million in its Series D funding round. Founded in 2020 by Doug Bernauer, an engineer with a twelve-year tenure at SpaceX, Radiant is headquartered in El Segundo, California. The company has swiftly progressed from completing its Series C funding just six months prior to achieving this latest capital raise, indicating strong investor confidence in its innovative technology.
