The Department of the Air Force (DAF) has moved forward with its Advanced Nuclear Power for Installations (ANPI) initiative, announcing specific company pairings to develop microreactors at three installations.
Radiant Industries will partner with Buckley Space Force Base in Colorado. Radiant is developing Kaleidos, a portable 1 MW helium gas-cooled microreactor using TRISO fuel. Factory-built and transportable by truck or aircraft, the unit requires no on-site water, relying instead on air cooling with fans and passive natural convection. It targets military installations among other resilient power needs. Radiant plans its first demonstration at Idaho National Laboratory’s DOME test bed, with criticality planned before July 4th.
Westinghouse will deploy at Malmstrom Air Force Base in Montana. Westinghouse brings decades of nuclear expertise and its eVinci microreactor. This heat-pipe cooled design produces about 5 MW, offering eight-plus years of fuel life with minimal maintenance. Fully factory-assembled and transportable in shipping containers, the unit operates without water cooling and supports remote or edge-of-grid applications while pairing well with renewables.


Great spots for some advertising. Titleist 1 in big letters would be eye-catching.
