Standard Nuclear Emerges from Stealth with $42 Million in Funding to Secure the Domestic Advanced Nuclear Fuel Supply Chain
With fresh funding, Standard Nuclear is accelerating the production of TRISO nuclear fuel for advanced reactors at industrial scale, emerging as the nation’s only reactor-agnostic TRISO fuel manufacturer and poised to transform domestic nuclear energy supply chains
OAK RIDGE, Tenn.–(BUSINESS WIRE)–Standard Nuclear, Inc., a reactor-agnostic producer of TRISO nuclear fuel, today announced its launch from stealth with $42 million in total funding led by Decisive Point with participation from Andreessen Horowitz, Washington Harbour Partners, Welara, Fundomo, and Crucible Capital.

As power demands surge for data centers, energy-intensive industries, and transportable energy solutions in defense and remote locations, Standard Nuclear is focused exclusively on supporting the advanced nuclear fuel supply chain through scaled production of TRISO, a critical and highly durable fuel for advanced nuclear reactors. Following decades of U.S. Department of Energy (DOE) scientific research, in 2019, the U.S. Nuclear Regulatory Commission (NRC) issued a safety evaluation report confirming the exceptional performance and robust safety profile of TRISO fuel, marking a significant step toward its use in advanced nuclear reactors.
Next-generation nuclear reactors, such as small modular reactors (SMRs) and micro reactors, will drive the future of reliable and flexible energy, but these systems require specialized advanced nuclear fuels to unlock their full potential. Currently, few companies are producing TRISO fuel, and production is limited to small batches for their own proprietary reactor designs. As the country’s first and only independent TRISO fuel manufacturer without reactor development operations of its own, Standard Nuclear’s model strengthens the advanced reactor supply chain by providing a reliable, independent source of fuel.
Standard Nuclear owns and operates a set of fully equipped commercial-scale facilities totaling 19,000-square-feet that sit on its 36.8 acre campus located at the former K-25 Nuclear site in Oak Ridge, TN. The Company operates its fully permitted radiological facilities to manufacture and supply TRISO fuel forms with varying specifications for its multiple commercial and government customers.
“As the demand for power accelerates, nuclear is a clear and practical solution. Advanced nuclear fuels like TRISO for small modular and micro-reactors are necessary to unleash American energy dominance and enable a future with abundant power,” said Thomas Hendrix, General Partner at Decisive Point and Executive Chairman of Standard Nuclear. “With the capital from this funding round, Standard Nuclear is positioned to deliver on our growing customer orders, accelerate our growth, and fill the domestic supply gap. We are rapidly scaling TRISO fuel production to advance our mission of securing the domestic supply chain and achieving energy independence.”
The Standard Nuclear team is comprised of over two dozen employees with 150+ years combined DOE National Lab experience. Founded in 2024, the company has booked $5 million in contracts in the first quarter of 2025, and signed a major fuel offtake agreement for over 1 MTU of fuel with an additional 1.5 MTU in negotiation, representing more than $100 million in non-binding fuel sales for 2027. In just a few months, the company has established strategic customer relationships for its various products and services with a diversified group of commercial and government customers including Radiant Industries, Antares, Nano Nuclear Energy, Jimmy Energy, The U.S. Department of Energy National Laboratories, and the Department of Defense.
“Most of the long-anticipated wave of advanced reactors finally arriving to market are harnessing the unique, inherent advantages of TRISO fuel—benefits that have been validated through decades of DOE and NRC investment and scientific rigor,” said Dr. Kurt Terrani, PhD, Chief Executive Officer of Standard Nuclear. “These reactors can’t run without fuel, and we’re here to ensure there are no uncertainties in that supply. We’re not just delivering TRISO fuel at scale—we’re doing it at a cost that enables a robust, competitive, and sustainable advanced reactor industry.”
About TRISO — The Most Robust Nuclear Fuel on Earth
Tristructural Isotropic (TRISO) particle fuel is composed of tiny uranium-bearing spheres encapsulated by successive layers of carbon and ceramic-based materials. Each TRISO particle, about the size of a poppy seed, acts as its own containment system for uranium and its radioactive fission products and eliminating the possibility of a meltdown event. The unique coated layer structure of TRISO particles enhances fuel performance and safety, making TRISO particularly well-suited for high-temperature gas-cooled reactors (HTGRs) and other emerging advanced nuclear reactors. TRISO production has been substantially de-risked, as its design and manufacturing processes have matured over six decades. Initially developed in the late 1950s and early 1960s for the Dragon Reactor, an HTGR, the technology saw meaningful advancements in the following decades. After various phases of research, development, and occasional dormancy, the U.S. Department of Energy revived and began further improving TRISO fuel in 2002 with the Advanced Gas Reactor (AGR) Fuel Development and Qualification Program, focusing on modernization of the manufacturing and quality control methods, as well as irradiation performance tests of UCO fuel kernel system.
The AGR program paved the way for further advancements in TRISO fuel, setting an international record by demonstrating that TRISO fuel could safely withstand temperatures up to 1800°C throughout a multi-year campaign led by Idaho National Laboratory (INL) and supported by Oak Ridge National Laboratory (ORNL). According to INL, the fuel performed even better than they expected. Based on these results, the NRC reviewed the data and gave a safety approval in 2019, further advancing TRISO’s widespread adoption as the premiere fuel for next-generation nuclear reactors.
Because of its excellent performance and safety qualities, TRISO fuel will be used in the vast majority of new reactor designs.
