Army Names Nine Candidate Bases for Janus Microreactors as DIU Opens Industry Call

Overview

• The Army identified Fort Benning, Fort Bragg, Fort Campbell, Fort Drum, Fort Hood, Fort Wainwright, Holston Army Ammunition Plant, Joint Base Lewis-McChord, and Redstone Arsenal after site assessments focused on mission needs and technical suitability.
• DIU released an Area of Interest under its Commercial Solutions Opening and Other Transaction Authority pathways, with initial responses due Dec. 15 for prototypes capable of up to 20 megawatts-electric using uranium fuel enriched to 20% or less.
• Selected vendors are expected to develop first-of-a-kind and second-of-a-kind microreactor power plant prototypes to demonstrate scalable production pathways.
• The Army specifies passive safety features, limits on radiation output, and operational controls accessible only from within the installation as core design requirements.
• Final site selections and contract awards remain pending, with DOE and national labs supporting evaluations and a staged rollout aligned to a program objective of placing units at installations by the end of 2030.
