Project Pele, the Department of War’s (DOW’s) first-of-its-kind transportable nuclear microreactor prototype, has received its tri-structural isotropic (TRISO) particle fuel at Idaho National Laboratory (INL), where formal system testing is slated to begin as early as 2027. The fuel—manufactured by BWXT Technologies (BWXT) and shipped from its Lynchburg, Virginia, facility—represents the first TRISO microreactor fuel […]

Idaho National Laboratory (INL) has selected the five commercial teams that will potentially demonstrate advanced applications—including data center integration—at its much-watched Microreactor Application Research Validation and Evaluation (MARVEL) platform, an 85-kWth/20-kWe liquid-metal-cooled test bed currently under construction at the lab. The initial selections, unveiled on Dec. 4, mark the “first potential end users for MARVEL,” […]

Advanced nuclear technology company Oklo entered into two separate high-profile collaborative agreements this week that seek to supply integrated energy solutions to data centers and large load industrial operations. The alliances—one with Liberty Energy, an energy services and technologies firm, and another with critical digital infrastructure provider Vertiv—mark the newest notch in the growing market […]

Nuclear microreactors developed separately by Westinghouse and Radiant are poised to become the first fueled designs tested at the Demonstration of Microreactor Experiments (DOME) facility—the world’s first dedicated microreactor test bed slated to open at Idaho National Laboratory (INL) in early 2026. The first fueled experiment is expected to begin as early as spring 2026. […]

In a new pilot program, the U.S. Department of Energy (DOE) issued an ambitious challenge: bring at least three advanced nuclear test reactors to criticality by July 4, 2026. Announced in June, the program sidesteps traditional Nuclear Regulatory Commission (NRC) licensing, seeking instead to authorize full-scale reactors on private sites through DOE’s internal review process. […]

The U.S. Department of Energy (DOE) is inviting private-sector nuclear developers to submit proposals for experiments and demonstrations using its Microreactor Application Research Validation and Evaluation (MARVEL) project. The first-of-its-kind operational test bed for advanced microreactor technologies is now 90% through its final design phase, with key components already under fabrication. Idaho National Laboratory (INL), […]

The U.S. Air Force has formally reaffirmed its selection of Oklo’s liquid metal-cooled fast reactor to provide nuclear energy at Eielson Air Force Base in Alaska, re-issuing a Notice of Intent to Award (NOITA) for the company’s Aurora Powerhouse following a comprehensive evaluation process. The June 10 announcement, issued by the Defense Logistics Agency Energy […]

Advanced nuclear plant developer Last Energy will build 30 microreactors at a site in Haskell County, Texas, a measure aimed at meeting the growing power demands of data centers across the state. The development comes as Texas faces increasing pressure to ramp up its power supplies to address an expansion of energy-intensive industries. The Washington […]

The need for emissions-free power generation, along with the ability to provide more power when and where it’s needed, is driving research and development of smaller nuclear reactors. Energy industry

While the past year has marked stunning triumphs for nuclear energy, experts caution that high costs, regulatory bottlenecks, and the need for market alignment remain major hurdles on the path to a true
