US Standard Nuclear and Radiant Sign TRISO Fuel Supply Agreement

Standard Nuclear announced on August 20 that it has signed a binding TRISO nuclear fuel supply agreement with Radiant Industries, Inc. of the United States. Under the agreement, Radiant will receive a multi-ton supply of TRISO fuel, with deliveries continuing through 2031, to support its microreactor deployment plans.

Standard Nuclear, headquartered in Oak Ridge, Tennessee, states that it is currently the only company in the United States with an industrial-scale TRISO fuel manufacturing facility. The agreement is aimed at Radiant's Kaleidos microreactor currently under development. The reactor has a power output of 1 megawatt and is designed to be transportable and deployable directly at customer sites.

Standard Nuclear stated that this multi-year supply arrangement reflects the growing demand for commercial-scale TRISO fuel supply capabilities in the advanced nuclear energy market. TRISO fuel, typically referring to tristructural-isotropic coated particle fuel, is adopted by multiple advanced reactor designs due to its coating structure's high temperature tolerance and fission product retention capabilities.

Kurt Terrani, President and Chief Executive Officer of Standard Nuclear, stated that Radiant is advancing the deployment of transportable, safe, and highly advanced microreactors for applications such as defense and customer-side power supply; this agreement reflects customer confidence in Standard Nuclear's ability to deliver critical TRISO fuel.

The company stated that its business focus includes large-scale production of advanced nuclear fuel and power systems, and it plans to expand domestic advanced nuclear fuel supply capabilities in the United States through multi-year customer agreements.
