What Nano Nuclear Energy Inc. does
In the company’s own words
NANO Nuclear Energy Inc. (Nasdaq: NNE) is a pre-revenue nuclear energy and technology company developing microreactors and businesses across the nuclear fuel cycle. Its reactor portfolio includes the stationary KRONOS MMR™ and portable LOKI MMR™ high-temperature gas-cooled reactors, both designed to use TRISO fuel, as well as the ZEUS™ solid-core battery reactor; the company is pursuing a sale of its ODIN™ reactor design. KRONOS is its lead development project, aimed at larger industrial users, population centers, and data centers, while LOKI and ZEUS target remote, portable, and other specialized applications. The company also plans to develop domestic low-enriched and high-assay low-enriched uranium fuel processing, commercial nuclear fuel transportation, and nuclear engineering and consulting services. These activities are at varying stages of development, and the company has not generated revenue since inception. Its KRONOS research and test reactor project involves the University of Illinois Urbana-Champaign, and its fuel-supply work includes a collaboration with LIS Technologies. The company acquired KRONOS and LOKI assets in 2025, including related intellectual property and project rights.
