Developing the Ultralight Modular Reactor (UMR) - the only portable nuclear fission power platform devised for aerospace, maritime, ground, and off-grid deployment, expanding military mission capabilities, supporting homeland security missions, and securing civilian infrastructure resilience.
Mission Assurance Power Platform for U.S. National Security
ULTRALIGHT MODULAR REACTOR
“Deploying Mission Assurance Physics Architectures for U.S. Strategic Deterrence” - advancing strategic capabilities in the national interest. The Ultralight Modular Reactor (UMR) is the first project of Defense Physics Laboratory within a broader portfolio of technologies designed to reinforce the national security enterprise. UMR addresses the critical need for mobility, grid independence, and high energy density power across military operations, space systems, homeland security strategies, and resilient civilian and industrial infrastructure.
Safeguarding America with Nuclear Resilience
THE NATIONAL INTEREST
Military Operations
Providing compact, durable power for forward operations, remote installations, expeditionary logistics, and electrically intensive defense systems, reducing diesel dependence and expanding the operational endurance of warfighting assets.
Spent Fuel Reduction
Creating productive energy and economic value from spent nuclear material while reducing long term waste concerns and opening a strategic pathway for reusable nuclear fuel cycle and back end nuclear services.
Grid Independence
Delivering reliable power without grid dependence in remote sites, permanent installations, and other austere or disrupted environments where continuous energy availability is essential.
Nuclear Forensics
Supporting detection, interrogation, diagnostic, and attribution missions through compact neutron generators and gamma spectroscopy systems for homeland security, cargo screening, and nuclear threat response.
Emergency Response
Delivering deployable power for disaster recovery, heat generation, potable water production, communications, and continuity operations where conventional infrastructure is damaged or unavailable.
Space Power Systems
Extending mission endurance through compact nuclear power for lunar systems, orbital infrastructure, and deep space missions where resupply, power density, and long duration performance are critical.
Resources Security
Supporting strategic industrial processes for hydrogen production, fresh water generation, mining and construction, and medical isotope production where dependable energy access directly enables national capability.
Maritime and Aerospace
Expanding maritime and aerospace mission capability through portable high energy density power for ships, aircraft, and unmanned systems requiring greater endurance, payload flexibility, and onboard power.
Critical Infrastructure
Reinforcing resilient power for critical communications and network facilities, transport systems, ports of entry, command centers, and other infrastructure essential to national continuity.
UMR is a compact, versatile, and mobile power platform designed to deliver reliable nuclear energy in environments where conventional power infrastructure is unavailable, vulnerable, or impractical. It is devised for simplicity of deployment, endurance, and expansion of mission capabilities.
