NuGen Engine
High-temperature gas-cooled microreactor by NuGen LLC, described by the IAEA's September 2026 microreactor outlook (IAEA/PAT/016) as a design that removes the need for on-site refuelling and holds Australian, British, Canadian and US patents. The outlook's status figure gives 4 to 6 MWth and conceptual design; the range is kept here rather than one stored number. No electrical rating is stated. This is a dated IAEA description, not confirmation of current availability, a named deployment or authorization.
