Radiant Nuclear, legally Radiant Industries, is a nuclear energy startup based in El Segundo, California, that designs portable, factory-built microreactors meant to replace diesel generators at hospitals, data centers, remote sites and military bases. Founded in 2020, the company is developing Kaleidos, a 1-megawatt fail-safe microreactor that can be transported by road and run for up to five years without refueling, with testing planned at Idaho National Laboratory and first customer deliveries targeted for 2028. It hires mechanical, turbomachinery, power electronics, electrical, embedded software, manufacturing and reactor operations engineers plus regulatory and government affairs staff.

About Radiant

Radiant is an El Segundo, CA-based company building the world's only mass-produced, transportable nuclear microreactors. The U.S. grid is under growing strain, with power demand accelerating, driving higher utility costs, rising carbon emissions, and interconnection backlogs. Radiant has a solution, transportable, on-site power. Our first reactor, Kaleidos, is 1 megawatt: small enough to be factory-built, transported by land, sea, or air, and deployed wherever power is needed. 1 MW can power 1000 homes for five years. Ship it back and we refuel for a 20 year operating life. We made energy a product that can be used for critical infrastructure like military bases, data centers, hospitals, and remote sites, as well as the commercial main street businesses that keep America running. Founded in 2020, Radiant is under contract to deliver power to the U.S. Army, Navy and Air Force and has signed pre-order agreements with Equinix, with deployments beginning in 2028.
