Radiant has delivered TRISO fuel to the Idaho National Laboratory for full-power testing of its Kaleidos microreactor at the Demonstration of Microreactor Experiments facility. This testing program aims to collect performance data to support the commercial licensing process with the Nuclear Regulatory Commission. The company plans to operate the reactor for 150 hours at full power to validate the system for future commercial deployment.

QuoteThe first shipment of fuel for full-power, full-temperature testing of Radiant's Kaleidos microreactor technology has been delivered to the National Reactor Innovation Center's Demonstration of Microreactor Experiments facility at Idaho National Laboratory. ;

The tri-structural isotropic (TRISO) fuel was fabricated by Standard Nuclear to Radiant's specifications earlier this year. It will be used to power Radiant's Kaleidos reactor to conduct a full-power, full-temperature test this summer, the company said, starting months of rigorous testing and validation. With fuel now on site, the company said it is "poised to bring Kaleidos online".
