The U.S. military is seeking to bolster the nuclear industry, announcing Tuesday that it will deploy a commercial microreactor on a domestic base within three years.

The Janus program follows President Donald Trump’s executive order directing the Department of Defense to open an Army-regulated nuclear reactor by 2028. DOD said the initiative aims to enhance national security and “help companies close their business cases as they seek ‘Nth-of-a-kind’ production.”

“The U.S. Army is leading the way on fielding innovative and disruptive technology,” said Secretary of the Army Dan Driscoll. “We are shredding red tape and incubating next-generation capabilities in a variety of critical sectors, including nuclear power.”

The news comes one day after startup Radiant Nuclear, which has a contract to deliver a microreactor to the Air Force, announced it would build the world’s first factory for mass-produced nuclear generators in Tennessee.
