Army spending $2B to build nuclear microreactors at 5 bases

The U.S. Army is investing $2.2 billion in the development of nuclear microreactors at five bases to firm up national security through more dependable energy. 

Nuclear microreactors can produce 1-20 megawatts of thermal energy that could be used directly as heat or converted to electric power.

Microreactors are built in a factory and are small enough to be transported on a truck, according to the Department of Energy.

They can operate for up to 10 years without refueling, according to the federal government.

Five private vendors were selected to facilitate the rollout of nuclear microreactors on military installations through a project known as the “Janus Program.”

Selected sites are primarily in the South and will helm efforts to build and operate nuclear reactors from fiscal 2027 to fiscal 2031.
