What Nano Nuclear Energy Inc. does
In the company’s own words
NANO Nuclear Energy Inc. (Nasdaq Capital Market: NNE) is a nuclear energy and technology company developing advanced clean energy solutions through proprietary reactor designs, intellectual property, and research methodologies. The company operates as a pre-revenue enterprise focused on comprehensive engagement across the nuclear power and energy industry, spanning from raw material sourcing through advanced nuclear microreactor development.
The company's primary business lines include nuclear reactor development, fuel processing, fuel transportation, and nuclear consulting services. Its lead reactor project is the KRONOS MMR™ Energy System, a high-temperature gas-cooled reactor utilizing TRISO fuel designed for both small and large-scale operations with modularity and scalable energy generation capabilities. The company also develops the LOKI MMR™ reactor, a portable nuclear reactor for versatile applications, and the ZEUS™ reactor, a portable modular solid core battery reactor. Through a January 2025 acquisition, the company obtained rights to these reactor designs and associated intellectual property from Ultra Safe Nuclear Corporation's bankruptcy estate for $8.5 million.
In its fuel processing business, conducted through subsidiary HALEU Energy Fuel Inc., the company is developing a domestic low-enriched uranium and high-assay low-enriched uranium fuel supply chain for both internal use and the broader advanced nuclear reactor industry. The company has made a $2 million strategic investment in laser-based uranium enrichment technology developer LIS Technologies Inc. and was selected as a key subcontractor in the Department of Energy's $3.4 billion Low-Enriched Uranium Enrichment Acquisition Program.
The fuel transportation business focuses on developing a high-capacity HALEU transportation system capable of moving commercial quantities of nuclear fuel across North America and internationally. The company holds an exclusive license for an advanced HALEU fuel transportation basket design and has engaged external partners for system optimization.
The company maintains significant collaborations with The University of Illinois Urbana-Champaign for KRONOS MMR™ development and with Idaho National Laboratory through a ten-year Cooperative Research and Development Agreement. Recent facility investments include a 14,000 square-foot nuclear technology branch in Oak Ridge, Tennessee, a demonstration facility in Westchester County, New York, and a regional facility in Oak Brook, Illinois. The company targets commercial launch of its KRONOS MMR™ reactor in the early 2030s, with subsequent reactor deployments anticipated thereafter.
