The Kaleidos Microreactor Design
Radiant is making significant strides in the advanced nuclear sector with the development of its Kaleidos microreactor. The Kaleidos is a compact, 1-megawatt, gas-cooled microreactor engineered specifically for transportability. Its innovative design allows it to operate for up to five years without the need for refueling, making it an ideal power solution for off-grid locations, remote data centers, and critical defense installations.
HALEU Requirements for High Performance
To achieve the remarkable power density and extended core life characteristic of the Kaleidos, the reactor relies on High-Assay Low-Enriched Uranium (HALEU). Standard low-enriched uranium reactors cannot match the performance metrics required for such a compact and long-lasting core. By utilizing HALEU, Radiant ensures that the microreactor can deliver reliable, baseload power in environments where traditional grid infrastructure is absent or vulnerable.
Securing the Fuel Supply Chain
Recognizing the critical nature of fuel availability, Radiant is actively securing its HALEU supply chain in parallel with the microreactor's development. The company recently signed a Memorandum of Understanding and a definitive multi-year contract with Centrus Energy to serve as its nuclear fuel supplier. Centrus will leverage its American Centrifuge Plant to provide the necessary uranium enriched between 5% and 20%, ensuring a domestic, reliable fuel source for the Kaleidos fleet.
