The service said it expects to field more than 20 microreactors across Department of Defense installations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The agreements, worth up to $2.2 billion combined, mark a step in the Army\u2019s Janus program, an initiative that aims to introduce microreactors to power installations independently rather than relying on civilian electrical grids. The Army <a href=\"https:\/\/www.army.mil\/article\/288903\/army_announces_janus_program_for_next_generation_nuclear_energy\" target=\"_blank\" rel=\"\">introduced<\/a> the program in 2025 after an <a href=\"https:\/\/www.whitehouse.gov\/presidential-actions\/2025\/05\/deploying-advanced-nuclear-reactor-technologies-for-national-security\/\" target=\"_blank\" rel=\"\">executive order<\/a> called for the military to speed up its integration of nuclear power, with the goal of having an operational reactor at a military base by Sept. 30, 2028. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cAwarding these contracts accelerates our ability to deliver safe, reliable baseload power directly to our installations,\u201d Secretary of the Army Dan Driscoll said in a release. \u201cWe are building the energy resilience necessary to project combat power globally, without relying on potentially vulnerable external grids.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The reactors will be contractor-owned and operated, the Army said, adding that vendors will only be paid if they hit technical milestones. Each installation will remain on the commercial power grid, officials said at a Wednesday media briefing, and the reactors are not intended to power the base completely. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Janus program follows the Pentagon\u2019s 2022 <a href=\"https:\/\/www.cto.mil\/pele_eis\/\" target=\"_blank\" rel=\"\">announcement<\/a> of \u201cProject Pele,\u201d which sought to develop a portable 40-ton nuclear reactor that could generate one to five megawatts of power.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">None of the base\u2019s future reactors use highly enriched \u2014 or weapon\u2019s grade \u2014 uranium, according to Jeff Waksman, principal deputy assistant secretary of the Army for Installations, Energy and Environment. In the briefing, he said the push toward nuclear energy stemmed from the nation\u2019s growing awareness of security risks and reliance on fossil fuel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cUnlike in prior conflicts, we now know that our domestic electric grid is potentially at risk in a conflict,\u201d he said during the briefing. \u201cWe also know that we will not necessarily be able to move fossil fuels easily wherever we need them to go. Right now, all critical infrastructure that the Army has is backed up by some form of liquid fossil fuel, primarily diesel.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Outside of the continental U.S., the threat remains, he said, as U.S. interests often rely on international ships.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe\u2019re often dependent. In a lot of our Pacific islands, we\u2019re dependent on foreign-shipped fuel from foreign-flagged vessels, and that doesn\u2019t give us a lot of comfort if there were to be a future conflict,\u201d he continued. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nuclear waste will not be stored on bases long-term, Waksman said. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The effort comes as the U.S. is currently at war with Iran, with both countries insisting that the Strait of Hormuz, in which around one-fifth of the global oil supply passes, is under their respective control. The war has driven up energy costs worldwide. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Installations were chosen based on a multilayered analysis including mission-set, power grid feasibility, environmental concerns and safety, according to Brandon Cockrell, deputy assistant secretary of the Army for Energy &amp; Sustainability. He also nodded to the bases\u2019 role in deploying troops.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIt\u2019s really difficult to look across the five and not draw the immediate conclusion that this is a direct link to power projection,\u201d he said, adding that such a component was part of the assessment. \u201cThis is because we have to be able to project power. We have to be able to meet the Army\u2019s mission if there is any vulnerabilities in the grid.\u201d <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In Nov. 2025, the Army said it was also <a href=\"https:\/\/www.army.mil\/article\/289074\/army_announces_next_steps_on_janus_program_for_next_generation_nuclear_energy\" target=\"_blank\" rel=\"\" title=\"https:\/\/www.army.mil\/article\/289074\/army_announces_next_steps_on_janus_program_for_next_generation_nuclear_energy\">considering<\/a> Fort Wainwright, Holston Army Ammunition Plant, Joint Base Lewis-McChord and Redstone Arsenal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Energy resiliency has become an increasingly important facet of technology development across the Army, which has pitted three contractors against each other to build a light tactical vehicle capable of producing large amounts of energy to power counter-drone systems, electronic warfare and directed energy weapons. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Army did not disclose the contract amounts for each nuclear microreactor company. Radiant, which has a contract tied to a Georgia base, disclosed that it secured an agreement totaling $750 million for 15 Kaleidos nuclear microreactors, which are currently undergoing testing at the Idaho National Laboratory DOME facility.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In a Wednesday release, the company said that the 1-megawatt microreactors would be transportable and \u201cplug-in ready.\u201d <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">General Atomics, which is tied to a Texas base, advanced its Tactical Energy System, or GA-TES, that has a baseline output of 5 megawatts and can scale up to 20 megawatts, a Wednesday announcement said. The GA-TES is transportable by rail or truck. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>The agreements, worth up to $2.2 billion, mark a step forward in the Janus program, an initiative to
