Radiant Industries, Inc. (United States) - Radiant is excited to announce a Request for Proposals (RFP) for TRISO UCO fuel fabrication.
Radiant's Kaleidos microreactor is powered by TRISO-coated UCO fuel. TRISO ensures each Kaleidos reactor will be meltdown-proof and able to reach higher burnup than traditional nuclear fuels. TRISO fuel has been called "the most robust nuclear fuel on Earth" by the US Department of Energy's Office of Nuclear Energy. The structural layers in each poppy seed-sized TRi-structural ISOtropic (TRISO) layered particle act as physical barriers to block the escape of fission products produced as the reactor operates. The uranium oxycarbide (UCO) fuel kernel reduces pressure on the TRISO layers by limiting CO and CO2 production throughout reactor operation.
Radiant is excited to announce a Request for Proposals (RFP) for TRISO UCO fuel fabrication. The Kaleidos fuel specification Radiant seeks to fabricate utilizes UCO kernel and TRISO layer geometry consistent with TRISO specifications already qualified.
Radiant aims to be a driver of commercial microreactor development and seeks to provide economical, reliable, zero-emissions solutions to the climate crisis everyone faces today. By procuring fuel for a demonstration unit meant to operate in 2026, Radiant and a selected fabricator will take a large step to making this a reality.
