Portable nuclear microreactors replacing diesel generators
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.

Radiant designs and manufactures portable, factory-built nuclear microreactors for off-grid power. Its Kaleidos unit is a 1 MWe high-temperature gas-cooled reactor that uses TRISO fuel and a helium coolant, packaged in a container-sized module that can be transported by truck, ship, or air for rapid deployment to remote sites. The reactor runs for up to five years between refueling as part of a 20-year lifecycle and operates without water cooling, enabling flexible siting. Radiant differentiates itself through factory production of certified HTGR-based microreactors with an ambitious R-50 factory to enable mass production and fast deployment for energy resilience, military, data centers, and critical infrastructure. The company aims to provide reliable, emissions-free power that replaces diesel and supports resilient energy infrastructure at remote or critical locations.
