NANO Nuclear Energy Inc. develops portable and stationary nuclear microreactors, including the patented KRONOS MMR stationary high-temperature helium gas-cooled reactor that produces 3.5-15 MWe electrical power and up to 45 MWth thermal power with molten salt storage for on-demand delivery, and the ZEUS solid-core battery reactor with a sealed core providing constant power for 10 years inside a shipping container. The KRONOS MMR supplies carbon-free electricity and high-temperature process heat to data centers, AI facilities, chemical and industrial operations, remote communities, and microgrids, while also supporting desalination, district heating, and hydrogen production. ZEUS targets remote locations and isolated regions for power generation and non-electric applications like hydrogen production. Subsidiaries include HALEU Energy Fuel Inc. for High-Assay Low-Enriched Uranium fuel fabrication, Advanced Fuel Transportation Inc. for HALEU fuel transportation to microreactor companies and national labs, and NANO Nuclear Space Inc. for the LOKI MMR space-capable microreactor. The company completed an initial public offering of $10.25 million in May 2024, followed by a $18 million offering in July 2024. Founded in 2022 by Jay Jiang Yu, Executive Chairman and President with prior nuclear technology entrepreneurship and capital markets experience at Deutsche Bank.
