About Radiant Nuclear

Radiant Nuclear is developing portable, containerized nuclear microreactors designed for remote locations and specialized applications. The company's Kaleidos reactor is designed to be factory-built, shipped via truck or cargo plane, and provide 1-10 MW of electrical power for remote communities, military bases, disaster relief, and industrial operations where traditional power infrastructure is impractical or unavailable.

The company is part of the advanced nuclear reactor movement that aims to make nuclear power more accessible, safer, and economically viable for smaller-scale applications. Radiant's approach focuses on helium-cooled, TRISO fuel-based reactors that can operate for several years without refueling. The technology targets markets currently served by diesel generators and other fossil fuel solutions in remote locations, potentially providing clean, reliable baseload power where renewable energy alone may be insufficient.
