The Department of the Army has selected five nuclear reactor developers, each paired with a different military installation, to move forward under its Janus Program for on base nuclear power. The companies named are Antares Nuclear, BWXT Advanced Technologies, General Atomics Electromagnetic Systems, Radiant Industries and Westinghouse Government Services. The announcement came during the second annual Nuclear Energy Conference and Expo in Dallas, Texas, cohosted by the American Nuclear Society and the Nuclear Energy Institute.
The Janus Program was established to deliver secure, resilient and reliable power to national defense installations and support critical military missions without relying solely on the commercial grid. In November 2025 the Army identified nine installations as potential locations to host microreactor demonstrations before narrowing the list to the five projects now moving forward. Jeff Waksman, principal deputy assistant secretary of the Army for installations, energy and environment, has been closely involved in developing the program and discussed its goals during the Dallas conference.
The selections add to a broader set of federal efforts pairing the nuclear industry with military and national laboratory programs, including the Nuclear Lifecycle Innovation Campuses and Nuclear Energy Launch Pad initiatives, both of which have drawn additional company participation in recent weeks. Federal officials have pointed to military bases as early customers for small and micro reactors because installations can host demonstration projects on federal land under simplified authorization pathways compared with commercial licensing.
The Janus awards mark one of the more concrete steps yet in translating federal policy attention on advanced reactors into specific projects tied to named developers and sites, with further design review and site specific work ahead before any of the five reactors reach construction.
