Nano Nuclear Energy designs portable microreactors (KRONOS, LOKI, ZEUS, ODIN) plus a fuel processing facility—think 'nuclear batteries in a box' for remote sites.
No revenue yet; the company burns cash, with net losses of USD 0.04B in fiscal 2025 and USD 0.01B in each of the prior two years.
Regulatory licensing and specialized fuel supply create barriers, but competitors like NuScale Power, Oklo, and X-energy are racing in the same microreactor space, and Nano Nuclear has no operating reactors or proven fuel pipeline yet.
