NextFin News - In a move that effectively ends a five-decade regulatory drought in the American nuclear sector, X-Energy Reactor Co., a prominent developer of advanced nuclear technology backed by Amazon.com Inc., received federal approval on Friday, February 13, 2026, to manufacture uranium fuel for next-generation reactors. The U.S. Nuclear Regulatory Commission (NRC) issued a Special Nuclear Material License to X-Energy’s subsidiary, TRISO-X, authorizing the commercial production of high-assay low-enriched uranium (HALEU) fuel at its facilities in Oak Ridge, Tennessee. This marks the first time in more than 50 years that the U.S. government has licensed a new category of nuclear fuel fabrication facility, specifically a Category II facility under 10 CFR Part 70.
The license grants TRISO-X a 40-year window to operate two production facilities at the Oak Ridge Horizon Center. The company is already constructing its first plant, TX-1, with fuel fabrication expected to commence by 2028. According to Investing.com, the NRC completed its safety and environmental reviews three months ahead of schedule, reflecting a heightened federal urgency to modernize the domestic nuclear supply chain. The facility will produce TRISO (tristructural isotropic) fuel pellets—tiny, poppyseed-sized beads of uranium encased in ceramic layers. These pellets are designed to withstand extreme temperatures without melting, offering a safety profile significantly higher than traditional nuclear fuels used in the current fleet of light-water reactors.
The timing of this approval is inextricably linked to the explosive growth of artificial intelligence and the resulting energy demands of Big Tech. U.S. President Trump, since taking office in 2025, has emphasized energy independence and the deregulation of the nuclear sector to support the American lead in AI. Amazon’s backing of X-Energy is a strategic play to ensure its massive data center expansions are powered by carbon-free, baseload energy. TRISO-X President Joel Duling stated that the approval closes a "longstanding gap" in the U.S. nuclear fuel cycle, which has historically relied on aging infrastructure and foreign imports for enriched material.
From an analytical perspective, this licensing is a watershed moment for the "Nuclear Renaissance 2.0." For decades, the primary bottleneck for advanced reactors—such as X-Energy’s Xe-100 small modular reactor (SMR)—has not been the reactor design itself, but the lack of a commercial fuel supply. Most advanced designs require HALEU, which is enriched to between 5% and 20% uranium-235. Until recently, Russia was the only commercial supplier of HALEU. By licensing TRISO-X, the NRC is effectively de-risking the entire SMR industry. Without a domestic fuel source, the 11 GW commercial pipeline X-Energy currently maintains—equivalent to roughly 144 SMR units—would remain a theoretical exercise.
The economic implications for the Tennessee region and the broader U.S. energy market are substantial. The TX-1 plant is part of the Department of Energy’s Advanced Reactor Demonstration Program, representing a public-private partnership model that is becoming the standard for high-capital energy projects. As TRISO-X moves toward its 2028 production target, it creates a localized ecosystem of high-tech manufacturing in Oak Ridge, a city with deep historical ties to the Manhattan Project. Furthermore, the design of TX-2 is already underway, intended to scale capacity to meet the projected demand from Amazon’s planned SMR deployments across Washington and Virginia.
Looking forward, the success of X-Energy will serve as a bellwether for other advanced nuclear players like TerraPower and Kairos Power. The NRC’s ability to accelerate its review process suggests a fundamental shift in regulatory culture, moving away from the stagnation of the post-Three Mile Island era toward a more agile, safety-focused framework. However, challenges remain. While the license is a victory, TRISO-X must still pass final NRC inspections of its safety systems and personnel training before the first pellet is pressed. Additionally, the broader industry must still solve the "chicken and egg" problem of enrichment capacity; fuel fabrication is only one step in a cycle that still requires a steady stream of enriched uranium feedstocks.
Ultimately, the marriage of Big Tech capital and advanced nuclear engineering, sanctioned by the U.S. President’s administration, suggests that the future of the American grid will be increasingly decentralized and specialized. The shift toward TRISO fuel represents a move toward "inherently safe" nuclear power, a necessary evolution to gain public and investor confidence. As Amazon and X-Energy lead this charge, the 2026 license will likely be viewed by future historians as the moment the U.S. nuclear industry finally regained its momentum.
