Launched in 2024 by the Defense Innovation Unit, in partnership with the Department of the Army and the Department of the Air Force, the Advanced Nuclear Power for Installations program seeks to design, license, construct, and operate microreactor nuclear power plants on military sites. The initiative focuses on creating decentralized, scalable systems capable of supplying full power to critical infrastructure.
Andrew Higier, Energy Portfolio Director at the Defense Innovation Unit, emphasized the program’s importance: “Projecting power abroad demands ensuring power at home and this programme aims to deliver that, ensuring that our defence leaders can remain focused on lethality.” He highlighted the value of leveraging recent advancements in the commercial nuclear sector to maintain a competitive edge in energy solutions.
The program also aims to utilize the Nuclear Regulatory Commission’s civil regulatory processes to encourage the development of commercial microreactor technology and strengthen related supply chains in the U.S. These efforts are intended to enhance energy reliability for military operations.
Daniel Klippstein, Senior Official Performing the Duties of Assistant Secretary of the Army, Installations, Energy and Environment, underscored the potential of the technology: “Advanced nuclear power represents a transformative opportunity to bolster Army installation resilience and strengthen national security in an increasingly uncertain world.” He noted that modern microreactor designs are more compact, safer, and efficient compared to older models, reducing dependence on external energy sources.
Supported by Idaho National Laboratory, the program defines a microreactor as a compact nuclear reactor producing up to 20 megawatts of thermal energy. This energy can generate electricity or provide heat for industrial uses. Most designs are portable, often transportable by truck, and capable of operating for years without refueling, making them suitable for remote locations.
These microreactors combine reliability with operational flexibility, offering a sustainable power solution for military bases. By integrating commercial innovations, the program aims to ensure consistent energy access, supporting mission-critical functions in diverse and challenging environments.
