TORRANCE, Calif. — August 27, 2026 — Antares announced today the execution of a binding multi-year fuel supply agreement (FSA) with Standard Nuclear (NYSE: STDN).
Under the FSA, Standard Nuclear will deliver up to eight MTUs of TRISO fuel to Antares through 2035. Antares will use the fuel to power its microreactors, which are engineered to provide safe, reliable, and resilient energy for fielded systems operating in the most demanding environments on Earth and in space, enabling critical mission capabilities for the Department of War and commercial customers where traditional power sources simply cannot.
“Antares exists to deliver nuclear power exactly where and when it is needed most, whether supporting stateside military installations, enabling persistent space operations, or powering mission-critical infrastructure far from the grid,” said Jordan Bramble, CEO and Co-founder of Antares. “Securing a long-term, industrial-scale supply of TRISO fuel from Standard Nuclear is a foundational step in moving our microreactors from demonstration to deployments. This partnership gives us the fuel certainty required to meet the strategic energy demands of our customers with the reliability and performance those missions require.”
The agreement builds on development work the companies have conducted together since 2025, including fuel specification, manufacturability, and production-path alignment. This locks in a secure, domestic supply of high-performance TRISO fuel for years to come. In doing so, it strengthens the U.S. advanced nuclear supply chain essential to national security and strategic energy independence.
“Antares is building reactors for some of the most demanding environments on earth and in space, and Standard Nuclear is proud to support Antares for their strategic energy applications,” said Kurt Terrani, CEO of Standard Nuclear. “We are working to scale our TRISO production capacity across identical facilities and continue to adhere to our customers’ needs. Now, as our customers move from demonstration toward commercial deployment, we are building the supply chain that advanced reactors need to meet their commercial needs and our nation’s energy and national security.”
