Strong Financial Performance, IPO Raises Over $1.1 Billion
U.S. advanced nuclear technology developer X-energy released its second-quarter financial report on August 14, reporting revenue and grant income of $54.6 million, a 154% increase compared to $21.5 million in the same period last year. Total revenue for the first half of the year reached $98 million, up 132% year-on-year. X-energy attributed the growth to progress in the commercialization of its Xe-100 high-temperature gas-cooled small modular reactor (SMR) and increased activities under the U.S. Department of Energy’s Advanced Reactor Demonstration Program (ARDP).
In April, X-energy completed its initial public offering (IPO), raising approximately $1.1 billion in net proceeds to fund subsequent commercial deployment. As of the second quarter, the company’s project pipeline in the U.S. and the U.K. includes 144 Xe-100 reactors, with a total installed capacity of approximately 11.5 GW. X-energy emphasized that the first deployments will be supported by corporate customers such as Amazon, chemical giant Dow, and UK energy company Centrica, demonstrating international market recognition for the Xe-100.
Accelerating HALEU Fuel Supply Chain Development
To secure the high-assay low-enriched uranium (HALEU) fuel supply required for future Xe-100 commercial deployment, X-energy has signed long-term enrichment service agreements with Centrus Energy and General Matter. HALEU is a critical fuel source for most advanced reactors, and the U.S. Department of Energy views it as a key component of nuclear industry expansion. Clay Sell, CEO of X-energy, stated that a stable HALEU supply will accelerate the commercialization of the Xe-100 and mitigate fuel shortage risks.
X-energy is also actively expanding its supply of nuclear-grade graphite. The company has partnered with German carbon materials manufacturer SGL Carbon, planning to invest up to $8 million to support the expansion of SGL Carbon’s plant in Chedde, France. The goal is to double Europe’s NBG-18 nuclear-grade graphite production capacity by 2030, enabling annual supply for up to eight Xe-100 reactors. X-energy noted that this move will effectively reduce supply chain risks and ensure large-scale deployment is not hindered by material shortages.
Expansion of Tennessee Fuel Park, TX-1 Facility Nears Completion
TRISO-X, X-energy’s fuel manufacturing subsidiary, has nearly completed the exterior construction of its first commercial nuclear fuel facility, TX-1, in Oak Ridge, Tennessee. Subsequent building and interior engineering are expected to begin in the third quarter. Once operational, TX-1 will become the first commercial TRISO fuel manufacturing plant in the U.S., producing fuel for Xe-100 high-temperature gas-cooled reactors.
To further expand capacity, X-energy recently secured $11 million in grants from the state of Tennessee to advance the construction of its second commercial fuel facility, TX-2, and a research and development center. Additionally, the company acquired approximately 70 acres of land near Oak Ridge, expanding the local fuel park’s total area to about 180 acres. X-energy anticipates that with the phased commissioning of TX-1 and TX-2, it will be able to meet the fuel demands of 144 Xe-100 reactors, providing stable support for the global energy transition.
The Xe-100 reactor is designed with an 80 MW power generation capacity and can be deployed modularly to meet industrial heating and electricity needs. With Amazon, Dow, and Centrica joining the initial deployment plans, X-energy is extending its reach from reactor design to a comprehensive supply chain encompassing fuel, critical materials, and manufacturing. Industry observers note that X-energy’s commercialization progress will offer new options for energy transition in the U.S. and the U.K., though the stability of the HALEU supply chain and regulatory approval timelines remain key challenges ahead.
