Radiant
Radiant develops the Kaleidos portable nuclear microreactor, designed to replace diesel generators and provide resilient power. The company has partnered with Idaho National Laboratory and received funding from the Department of Defense for its innovative energy solutions.
Company Overview
Radiant is a company that specializes in developing portable nuclear microreactors designed to generate electricity. Their flagship product, the Kaleidos microreactor, is intended to replace diesel generators in remote locations and provide robust backup power for critical infrastructure such as hospitals, data centers, and military installations. The company offers Power Purchase Agreements (PPAs) and direct unit sales to customers.
Innovative Energy Solutions
Radiant is at the forefront of energy innovation with its development of the Kaleidos microreactor. This compact nuclear reactor package includes all necessary equipment to generate electricity and can achieve full power within one day of installation. Kaleidos operates without requiring on-site water, utilizing air cooling through fans, and features high-speed turbomachinery for efficient operation. Additionally, Kaleidos can generate 1.9 MW of thermal power for applications such as facility heating or water desalination.
Advanced Nuclear Technology
Radiant employs advanced nuclear technology in its Kaleidos microreactor, leveraging meltdown-proof TRISO fuel and helium gas to transfer heat without radioactivity. The air jacket cooling system allows for passive core cooling through natural convection. These features simplify regulatory approval processes. The microreactor achieves over 110 times the energy density of existing diesel systems and is able to operate efficiently from 30% to 100% power, providing 1.2MW of electrical output for resilient microgrids.
Partnerships and Funding
Radiant has received a $3.8M Operational Energy Capability Improvement Fund Award from the Department of Defense to develop high-performance turbomachinery for a compact CO2 cycle power generation system. Furthermore, the company has partnered with Idaho National Laboratory in a $3.9M Front-End Engineering and Experiment Design (FEEED) Program to advance testing of the Kaleidos microreactor. These collaborations are essential in accelerating the development and deployment of their advanced nuclear technologies.
Fleet Monitoring and Maintenance
Radiant uses a centralized 24/7 fleet monitoring system to track the health of each Kaleidos reactor. After five or more years of operation, the fuel within the reactor is depleted and the entire container can be shipped back for refueling. Each Kaleidos unit can be fueled up to four times, resulting in a 20-year product lifetime. The units are mass-producible and are assembled, fueled, and tested in the factory for efficient and streamlined deployment. They can be delivered via truck or expedited by aircraft.
