El Segundo, CA

Radiant Industries is an El Segundo, CA-based startup developing Kaleidos, a portable, containerized nuclear microreactor. Portable nuclear power with rapid deploy capability can replace diesel generators used today to provide critical asset support for hospitals, datacenters, and military bases or to power microgrids at remote sites. Radiant’s unique yet practical approach to nuclear development utilizes modern software engineering to rapidly achieve safe, factory-constructable microreactors leveraging existing, well-qualified materials. Radiant will demonstrate the first fueled operation of a new commercial nuclear reactor design four years from now, which is the first step in demonstrating new nuclear reactor designs are a feasible, rapidly-deployable alternative to fossil fuels.
