Multiple small nuclear reactors to power US Army bases within a year

The U.S. Army, in partnership with the Department of Energy, has announced the Janus program to deploy multiple small nuclear reactors at military bases, particularly in the Pacific region, within the next year. These next-generation microreactors aim to provide resilient, secure, and uninterrupted power to national defense installations, reducing reliance on vulnerable fossil fuel supply chains such as diesel generators. The reactors are designed to operate for decades without refueling or servicing, enhancing energy security and operational readiness for forward-deployed forces. Janus builds on earlier efforts like Project Pele, which focuses on mobile, transportable microreactors using advanced fourth-generation nuclear technology, with operational reactors expected by 2026. The program aligns with Executive Order 14299, mandating the deployment of Army-regulated nuclear reactors at domestic military installations by 2028. The Army will lead Janus with support from the Department of Energy, emphasizing safety, oversight, and integration with the full nuclear fuel cycle to strengthen defense and industrial capabilities.
