What Happened to Actinide Inc.?

The landscape of uranium enrichment in Dallas has seen notable developments, primarily centered around the emergence of new startups aiming to address critical gaps in the domestic nuclear fuel supply chain. On August 26, 2026, Actinide Inc., a Dallas-area startup, announced a significant technological achievement: the successful enrichment of natural uranium to 15.38% uranium-235 using its 'Endurance' calutron. This demonstration represents a lab-scale pathway to producing High-Assay Low-Enriched Uranium (HALEU), a specialized fuel required by many advanced nuclear reactor designs. The use of a calutron, a technology historically associated with the Manhattan Project, marks a novel approach in modern enrichment efforts.

This breakthrough by Actinide Inc. comes at a time of increasing global demand for nuclear fuel and a strategic push by the United States to reduce its reliance on foreign suppliers, particularly Russia, for enriched uranium. The U.S. government has expressed urgency in increasing domestic uranium enrichment capacity, including HALEU production capabilities, especially with a ban on Russian uranium imports set to begin in 2028.

Another prominent Dallas-headquartered company contributing to this effort is ASP Isotopes Inc. (ASPI), through its wholly-owned subsidiary Quantum Leap Energy LLC (QLE). Founded in 2021, ASPI has been developing proprietary Aerodynamic Separation Process (ASP) and laser-based Quantum Enrichment (QE) technologies for isotope enrichment, including uranium. While QLE specializes in uranium conversion (the step before enrichment), it is also actively involved in plans for HALEU and LEU+ production facilities in the U.S.

Key turning points for ASPI/QLE include a non-binding Memorandum of Understanding signed on May 11, 2026, with a European nuclear technology company for the potential long-term supply of HALEU, with deliveries potentially starting in 2028. Prior to this, in March 2026, QLE entered into an agreement with a large, publicly-traded U.S. energy company to evaluate support for establishing advanced nuclear fuel cycle facilities in the U.S. These facilities are planned to produce HALEU and LEU+, as well as offer uranium conversion and deconversion services. Furthermore, in July 2026, QLE signed a research agreement with the Texas A&M Engineering Experiment Station (TEES) to advance uranium conversion technology, aiming to improve efficiency and scalability.

The consequences of these developments are significant for U.S. energy security and the deployment of advanced nuclear reactors. Domestic HALEU production is crucial for the next generation of small modular reactors (SMRs) and other advanced designs, which offer enhanced efficiencies and longer operating cycles. The efforts by Dallas-based startups like Actinide Inc. and ASPI/QLE are directly contributing to establishing a resilient and secure domestic nuclear fuel supply chain, reducing geopolitical vulnerabilities. As of August 26, 2026, Actinide Inc. has demonstrated lab-scale enrichment, while ASPI/QLE continues to advance its technology and forge partnerships for commercial-scale HALEU production and conversion facilities in the United States.
