Key Facts
- Fact 1: Back in October 2025, the U.S.
- Fact 2: Army unveiled the Janus Program to supply portable nuclear microreactors to military bases by 2028.
- Fact 3: Whereas these reactors are much smaller than conventional nuclear plants, they typically generate 1-20 megawatts of electricity per reactor, significantly more than what the biggest portable generators can manage.
- Fact 4: Army has awarded up to $2.2 billion over five years to both private and public companies to build, own, and operate commercial nuclear microreactors at five domestic military bases, estimating that 20 microreactors will be deployed under the program.
Back in October 2025, the U.S. Army unveiled the Janus Program to supply portable nuclear microreactors to military bases by 2028.
Whereas these reactors are much smaller than conventional nuclear plants, they typically generate 1-20 megawatts of electricity per reactor, significantly more than what the biggest portable generators can manage. That makes them ideal for the military, considering that major military bases consume as much power as a small city. The military logic is that in a conflict, transporting fossil fuels to remote front lines creates an easy target, while localized nuclear reactors can operate for years without refueling.
