nanonuclearenergy.comNano Nuclear Energy Inc (NASDAQ: NNE) is a pre-revenue nuclear energy company developing portable microreactor and fuel transportation technologies. The company has not generated meaningful revenue since inception, as disclosed in its 10-K filed December 18, 2025. NNE is developing three core products: the ZEUS microreactor, a solid-core nuclear battery for remote and off-grid deployments; the LOKI MMR, a transportable microreactor rated at 1 MWth to 5 MWth for terrestrial, marine, and space applications; and the KRONOS MMR Energy System. NNE also holds an exclusive, royalty-bearing patent license from Battelle Energy Alliance for HALEU nuclear fuel transportation technology, acquired April 3, 2024.
