U.S. Army Selects Five Firms for Project Janus Microreactors

The U.S. Army has selected five companies to construct small nuclear power units at five domestic military installations through Project Janus.

The initiative aims to reduce reliance on fossil fuels and support energy independence at military sites. Up to 20 microreactors could eventually operate across the bases, pending additional private investment from the participating companies.

Antares Nuclear is assigned to Fort Bragg in North Carolina, BWXT Advanced Technologies to Fort Campbell in Kentucky, General Atomics Electromagnetic Systems to Fort Hood in Texas, and Radiant Industries to Fort Benning in Georgia. Westinghouse Government Services will handle Fort Drum in New York.

The companies will share up to $2.2 billion through fixed-price milestone payments tied to construction progress. The contracts are based on the same milestone structure used for Project Janus.

Jeff Waksman, the Army’s principal deputy assistant secretary for installations, energy and environment, said the domestic electric grid could be at risk during a conflict and that moving fossil fuels may not always be possible.

The United States currently has no operational nuclear microreactors and produces only a small share of global uranium supplies. Officials say uranium availability will require coordination across federal agencies. Early deployments will focus on accessible sites within the 50 states before any possible expansion overseas or to islands.
