Janus microreactors will be licensed by the Army Reactor Office, not the NRC, on a defense-only path built to line up later commercial approvals.

Five Army posts from Bragg to Drum will host commercial microreactors, with vendors named and a 2028 clock.

On 26 August the Army selected five companies to own, build and operate commercial microreactors at five posts, drawing on up to $2.2 billion from fiscal 2027 through 2031. The first Army-regulated machine is supposed to run by 30 September 2028.

The 2026 Economic Report wants NRC time cut toward a year and nuclear grown toward 400 gigawatts by 2050. Day-one energy policy ended the LNG pause. The MAGA years, in office, are an energy file: nuclear that can get a yes, gas that can get a dock.
