US firm sells unique ODIN nuclear microreactor design to UK buyers

US-based NANO Nuclear Energy has signed a $6.2 million letter of intent to sell its proprietary ODIN microreactor design to UK firm Cambridge AtomWorks. The ODIN microreactor is an advanced portable nuclear reactor utilizing High-Assay Low-Enriched Uranium (HALEU) with enrichment levels up to 20%. Its design emphasizes safety and reliability through low-pressure coolant systems and natural convection for efficient heat transfer during operation and shutdown. The reactor also features a unique reactivity control system to ensure robustness. Cambridge AtomWorks, led by nuclear experts from the University of Cambridge and previously a consultant on ODIN’s development, is described as a “natural buyer” for the technology. The transaction is expected to close by the end of 2025. Following this sale, NANO Nuclear plans to focus its efforts on its portfolio of gas-cooled advanced microreactors, including the KRONOS MMR Energy System, LOKI MMR, and ZEUS. The company
