A look inside a lab making the advanced fuel to power growing U.S. nuclear energy ambitions
OAK RIDGE, Tenn. — Near signs that warn of radioactive risk at Oak Ridge National Laboratory, a half-dozen workers from the nuclear power company X-energy are making what appear to be gray billiard balls. Inside, they're packed with thousands of tiny black spheres that each contain a speck of uranium enriched beyond what today's power plants use. The United States is chasing a new age of nuclear power that banks on domestic production of reactor fuel like X-energy is making, and though the work at Oak Ridge is unfolding across just 3,000 square feet, X-energy and others are already revving up for big production. President Donald Trump set a goal of quadrupling domestic production of nuclear power within the next 25 years, signing executive orders in May to speed up development. A new wave of advanced nuclear reactors could be operational around 2030. But just like cars won't run without gas, those plants won't run without fuel. To expand nuclear energy long-term, the nation must maximize its nuclear fuel production, according to Trump. In Oak Ridge, X-energy has broken ground on a massive, nearly $2 billion campus for a new fuel fabrication facility, the first in the United States in over half a century. The nuclear fuel company Standard Nuclear, also in Oak Ridge, aims to produce metric tons of fuel for advanced reactors. A supplier named Orano is likewise looking to build a multibillion-dollar uranium enrichment facility nearby. 'This is a unique time,' said Tyler Gerczak, Oak Ridge National Laboratory's principal investigator for the cooperative with X-energy's subsidiary TRISO-X. 'The momentum is incredible.' Making the 'most robust nuclear fuel' The Associated Press toured the lab where X-energy is making small amounts of fuel for testing. Anyone beyond a magenta-and-yellow chain that warns of radioactivity must wear gowns, two layers of gloves and radiation monitors. When they leave, they're tested for radioactivity. X-energy, a Maryland-based company, uses uranium to make so-called TRISO fuel — inside what's known as 'pebbles.' Those are the billiard balls. The Energy Department says it's the most robust nuclear fuel on Earth because the particles cannot melt in a reactor. At the lab, the first step is making a uranium cocktail that resembles dark yellow lemonade. Uranium powder, in the form of triuranium octoxide, gets added to nitric acid, said Dan Brown, vice president of fuel development for TRISO-X. Then carbon and an organic solution are added. They have two glass containers set up — one wears a heated jacket, looking almost like a little sweater, that helps the uranium dissolve into the acid solution. The second cools the acid solution while the carbon source is added, which turns the mix near-black, he said. At another station, in a long clear tube, the cocktail solidifies into small black spheres with a jellybean-like consistency. Those black balls, about the size of poppyseeds, then travel through machines under temperatures as high as 1,800 degrees Celsius to get protective carbon coatings — like candy dipping — that make them look like very tiny BBs. X-energy uses graphite and other cohesive materials to bind 18,000 kernels together into a larger sphere. That gets coated in a final layer of graphite to seal the final pebble. In the end, it's strong enough to withstand the weight of an SUV. The pebbles will eventually give up their energy in the high-temperature gas-cooled nuclear reactor X-energy is developing, with about 220,000 pebbles per reactor, like gumballs in a gumball machine. When they exit the bottom, if energy remains, the pebbles will return to the top for another pass. Each one could be used about six times. X-energy also plans to make fuel products for other advanced reactor designs. The national laboratory lends X-energy its expertise, research and high-tech equipment for analysis and will evaluate samples, as will some universities. Other samples are archived. Idaho National Laboratory received a batch for its advanced test reactor, Brown said. Critics of building more nuclear reactors say they're too expensive and riskier than other low-carbon energy sources. 'Without a substantial decrease in construction costs, it's not worth the avoided greenhouse gas emissions,' said David Kemp, a Cato Institute policy analyst. Kemp said Trump's 25-year quadrupling goal is unrealistic because it would mean building nuclear reactors faster than ever. The United States lacks any next-generation reactors operating commercially and only two new large reactors have been built from scratch in nearly 50 years. Those two, at a Georgia nuclear plant, were completed years late and at least $17 billion over budget. Working to 'amp up' domestic nuclear fuel production Many next-generation reactors will use high-assay low-enriched uranium. It's fuel that's enriched to a higher level than traditional large nuclear reactors use, allowing the newer reactors to run longer and more efficiently, sit on smaller footprints and produce less waste, according to the Department of Energy. There's little of it made in the United States right now. Only Russia and China currently have the infrastructure to make large amounts of high-assay low-enriched uranium. In the United States, Centrus Energy produced the nation's first 20 kilograms of high-assay low-enriched uranium in more than 70 years in late 2023, to show it can produce limited quantities for commercial reactors. A big takeaway from Trump's executive orders is the need to 'amp up' domestic production of nuclear fuel to reduce dependence on foreign sources and enable in the long term expansion of American nuclear energy, according to the Energy Department. At the Nuclear Energy Institute trade association, Benjamin Holtzman, director of new nuclear, said he thinks the fuel will be ready for a new generation of U.S. nuclear reactors needed to meet the growing demand for electricity — if the right actions are taken now. X-energy CEO J. Clay Sell said he hopes to help solve the fuel problem so it doesn't hold back new reactor development. The Energy Department has awarded funding to X-energy. Amazon invested in X-energy too, and they're collaborating to bring more than 5 gigawatts of new U.S. power projects online by 2039. X-energy is the only one with an application before the U.S. Nuclear Regulatory Commission to license a new fabrication facility to transform enriched uranium into fuel products for nuclear reactors. Another applicant has asked to amend an existing license to make fuel for advanced reactors, according to the NRC. About five additional companies have told the NRC they are interested in making fuel for advanced reactors. X-energy's pilot lab at the National Laboratory started in 2016. The company now has 100 acres in Oak Ridge and growing for its nuclear fuel production complex. The first factory could be operational by late 2027 or early 2028, capable at full operation of assembling enough fuel orbs to power 11 of its new-age reactors; a second by late 2029, with a capacity four times greater, said TRISO-X President Joel Duling.

Standard Nuclear Emerges from Stealth with $42 Million in Funding to Secure the Domestic Advanced Nuclear Fuel Supply Chain
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. 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 Share 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 — T he 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. 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 both terrestrial 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. For more information, visit:
