Five companies, five bases: The Army’s Janus Program takes shape
Between the Nuclear Lifecycle Innovation Campuses and Nuclear Energy Launch Pad programs, August has already been a busy month for federal partnerships with the nuclear industry.
That trend continues: On Wednesday, the Department of the Army announced that it has selected five nuclear reactor developers—Antares Nuclear, BWXT Advanced Technologies, General Atomics Electromagnetic Systems, Radiant Industries, and Westinghouse Government Services—each paired with a different military installation, for its Janus Program.
This week, the nuclear community descended on Dallas, Texas, for the second annual Nuclear Energy Conference and Expo, the premier industry-focused nuclear conference cohosted by the American Nuclear Society and the Nuclear Energy Institute. Among the plenary panelists was Jeff Waksman, principal deputy assistant secretary of the Army for installations, energy, and environment. Waksman has been closely involved in the development of the Janus Program, and the morning before the program’s new selections were unveiled, he provided insights on its ultimate goals at NECX 2026.
