+10Remote locations and critical infrastructure often rely on diesel generators for power, which are expensive, polluting, and require frequent refueling. Existing power grids can be unreliable, and alternative energy sources like solar and wind are intermittent, necessitating a continuous and dependable power supply.
Radiant's Kaleidos is a portable nuclear microreactor designed to replace diesel generators, providing a clean and continuous power source. The reactor generates 1.2 MW of electricity and 1.9 MW of thermal power, and can be rapidly deployed to provide resilient backup power for hospitals, datacenters, military installations, and remote villages. Kaleidos requires no on-site water use, leveraging air cooling, and eliminates the need for on-site nuclear waste disposal, as the entire unit is shipped back to the factory for refueling after 5 or more years of operation. The system can operate efficiently from 30% to 100% power, enabling resilient microgrids and enhancing existing renewables infrastructure.
The primary customers are military and commercial entities in need of a reliable and clean alternative to diesel generators, including remote villages, hospitals, datacenters, and military installations.
