Crusoe nuclear-powered AI data center demo at Idaho National Laboratory
Also called: Aalo-X / Project Ascension, Crusoe Spark INL
A small test data center on Idaho National Laboratory land, to be powered directly by a new mini nuclear reactor. The companies call it a proof of concept for 2027. It is on federal land, so the county does not zone it.
Where things stand: Announced July 30, 2026 as a demonstration planned for 2027.
