Standard Nuclear Announces Licensing and Construction Milestones Across Expanding Nuclear Fuel Production Footprint Construction of two new advanced fuel production facilities in Tennessee and Idaho substantially complete, advancing toward commissioning, regulatory approval, and initiating production Both facilities receive Preliminary Documented Safety Analyses (PDSAs) approval from US Department of Energy Oak Ridge, TN — July 22, 2026 — Standard Nuclear (NYSE: STDN), a reactor-agnostic producer of TRISO nuclear fuel, today announced construction and regulatory approval milestones across two of its upcoming nuclear fuel production facilities, marking a major milestone as the company works to expand its capacity for bulk production of advanced nuclear fuel from its existing footprint. The company announced construction is substantially complete for SN-TN and for SN-ID, two new identical facilities capable of collectively adding up to 5 metric tons of uranium (MTU) per year of additional TRISO production capacity once fully scaled, with the facilities initially expected to provide up to 1 MTU of additional annual capacity each. The company expects start-up, commissioning, and licensing activities to advance for both facilities over the summer. In parallel with these construction milestones, Standard Nuclear has received approval of Preliminary Documented Safety Analyses (PDSAs) for both of these nuclear facilities from the U.S. Department of Energy. Once fully authorized by the U.S. Department of Energy, these fuel lines are intended to operate as Hazard Category 2 (HC-2) nuclear facilities. Standard Nuclear today operates its existing SN-0 facility in Oak Ridge, TN, which is currently producing TRISO with the ability to produce up to 0.5 MTU annually. The company’s ability to rapidly execute the buildout of multiple, strategically located sites is enabled by its rigorous process toward repeatable facility design, vendor engagement, and modular production-line replication, all of which can help reduce design uncertainty for a first-of-a-kind construction platform. “This comprehensive milestone represents the core of our mission at Standard Nuclear: focused execution to scale quickly to meet the increasing customer demand for advanced nuclear fuel,” said Kurt Terrani, CEO of Standard Nuclear. “Our ability to deploy additional production lines rests on the maturity of our modular manufacturing framework, allowing replication of safe and proven systems that allows us to scale quickly, reducing time-to-market while maintaining a lean capital footprint. This same framework maturity, coupled with the incredible support and technical assistance we have received from Idaho National Laboratory experts, helped streamline our progress through DOE’s rigorous nuclear facility licensing process as we aim to fulfill our mission to fuel the nation's advanced reactor fleet.” In addition, the company is continuing to build out another fuel line as a part of its joint venture with Framatome, Inc., leveraging the latter’s existing NRC license, in Washington state. Expanding domestic nuclear capacity depends on a fleet of inherently safe advanced reactors, many of which rely on TRISO-based fuels designated as 'functional containment' by the NRC. As a high- performance, precision-engineered fuel, TRISO carries the primary safety function within the reactor core.
Standard Nuclear is scaling its proven TRISO production to ensure the world's best-in-class TRISO- fueled reactors are supported by a robust and reliable supply chain. With construction in Tennessee and Idaho substantially complete, Standard Nuclear is now focused on final facility commissioning, finalizing regulatory approvals, and initiating production in alignment with customer requirements and timelines. About Standard Nuclear Standard Nuclear’s mission is to reliably deliver the essential building blocks of nuclear power at scale — enabling cost-effective, safe, and secure energy for the world. Supported by leading U.S. defense technology and critical infrastructure investment firms, Standard Nuclear is focused on the large-scale production of advanced nuclear fuel and radioisotope power systems. It is the nation’s only independent manufacturer of TRISO fuel — a robust, high-performance fuel essential to advanced nuclear reactors for terrestrial, national security, and space applications. Standard Nuclear offers a reactor-agnostic supply of advanced fuels to the next-generation nuclear industry and delivers dependable radioisotope power solutions to the space and defense sectors. Through these efforts, it is helping to eliminate U.S. reliance on geopolitical adversaries for these strategically vital technologies.
