From Arctic research stations to remote island grids to operational military installations, our microreactor is purpose-built for locations where traditional energy sources fall short.

With plug-and-play infrastructure, rapid deployment, and transportability by truck or rail, the GA-TES Tactical Energy System liquid metal cooled reactor sets a new standard for resilient, compact nuclear power—delivering reliable energy wherever it’s needed most.

Engineered to thrive in remote, off-grid, and extreme environments, the rugged GA-TES reactor delivers clean, dependable energy—when and where it matters most.

Resilient Power

  • Output Range: 3–10 MWe, scalable to meet mission-specific needs
  • Black Start Capability: Enables full autonomous grid restart without external power
Safety is at the core of every design decision we make.

Built-In Passive Safety

  • No Moving Parts: Reduces failure modes and simplifies operation
  • Passive Cooling and Shutdown: Requires no operator intervention or external power
  • Non-Pressurized Reactor Vessel: Enhances safety by eliminating high-pressure risks
  • No Primary Piping: Compact, inherently safe design with fewer potential leak points
  • Coolant Never Becomes Radioactive: Simplifies maintenance and limits contamination risks

Fuel for the Future

  • Fuel Type: UZrH, High-Assay Low-Enriched Uranium (HALEU)
  • Supply Chain Ready: Commercially available through existing pathways
  • 5-Year Core Life: Operates for nearly five years without refueling
  • >30-Year Plant Lifetime: Engineered for long-term deployment with minimal on-site servicing required

Our patented and proven UZrH fuel pellets, already tested and qualified in other reactor types, ensures regulatory confidence and operational reliability.

Minimal Maintenance. Maximum Uptime.

  • No Pumps, No Valves, No Mechanical Complexity for the cooling system: Utilizes natural circulation for both primary and secondary coolant loops
  • No Emergency Backup Power Required: Fully self-sufficient for both operational and safety needs
  • Simplified Upkeep: Streamlined maintenance reduces labor, cost, and downtime
Designed for unattended or customer-mandated minimally-attended operation, reducing operational staffing needs and lifecycle costs.
