Scott Nolan, a former SpaceX engineer, has founded General Matter, a San Francisco-based startup aiming to break Russia’s monopoly on high-assay low-enriched uranium (HALEU) and produce it at scale in the United States. The company plans to meet the growing demand for HALEU, a type of uranium enriched between 5% and 20%, which is essential for next-generation nuclear reactors, such as small modular reactors (SMRs), expected to be pivotal by the 2030s.
Aims to Revolutionize U.S. Nuclear Fuel Production
HALEU is key for advanced reactors, offering more efficient energy production than the standard uranium fuel used in current reactors. Companies like Amazon are exploring the use of such reactors to power data centers, underscoring the fuel’s importance. Nolan’s vision for General Matter includes not only ramping up domestic HALEU production but also significantly reducing its costs.
Nolan aims to halve HALEU enrichment costs in the long term, which are currently elusive but estimated between $25,000 and $35,000 per kilogram. This price is largely driven by Russian production, creating vulnerabilities for U.S. energy security.
U.S. Government Support and Industry Competition
The U.S. Department of Energy (DOE) awarded initial contracts to General Matter and three other companies in October as part of a push to kickstart domestic HALEU production. These contracts are part of a $2.7 billion initiative, pending Congressional approval. However, General Matter faces stiff competition from established companies like Urenco USA, Orano USA, and Centrus Energy, which already have infrastructure and expertise in uranium production.
Challenges and Controversy
While HALEU holds potential for revolutionizing the nuclear energy sector, critics have raised concerns about its enriched levels, fearing potential military uses. Nolan emphasized that his company would rely on regulators to set safe enrichment levels, likely between 10% and 12%.
SpaceX-Inspired Approach to Technology
Nolan’s approach to HALEU production takes inspiration from his time at SpaceX, where technological innovation and cost-cutting were central. At General Matter, he plans to combine nuclear industry experience with the agility of the technology sector to rethink uranium production methods. The startup’s approach could include novel techniques like lasers, in addition to the more traditional high-speed centrifuges used for uranium enrichment.
