Powering the AI revolution and the industrial infrastructure of tomorrow
The ARC-100 delivers 100MWe of firm, clean baseload power. Built for campuses and grids that cannot tolerate interruption. 30 years of prototype operating experience. Simple, low pressure, modular design.
AI never sleeps. Neither does its power source. The ARC-100 delivers 100 megawatts of firm, clean baseload. Built for customers who demand reliable power without compromise.
Engineered for firm, dispatchable power
The ARC-100 is a sodium-cooled fast reactor using metallic fuel, leveraging proven technology and ongoing licensing engagement in the US and Canada.
30 Years of Real Data
The ARC-100 refines the underlying technology of the EBR-II which operated successfully at Idaho National Laboratory for over 30 years.
EBR-II, Argonne National Laboratory, 1964–1994
AI-Ready Infrastructure
24/7 high-density baseload with true load following. Compact enough to co-locate directly on a hyperscale campus. No grid dependency.
Accelerated Path to Power
Factory-fabricated modules ship to site for rapid assembly, enabling a streamlined transition from first concrete to power generation.
Passive Safety
Sodium coolant operates at atmospheric pressure. If every system fails, the reactor shuts itself down. No operator action. No external power.
Demonstrated: EBR-II loss-of-flow test, April 3, 1986
20-Year Fuel Cycle
One fuel load runs for two decades. No refueling outages. No exposure to uranium spot prices. Energy cost is locked at signing.
Multi-Unit Scalable
Deploy multiple units on a single site to match demand. 100MWe to 600MWe+. Each unit fits within a city block footprint.
Where the ARC-100 goes to work
AI Data Centers
100MWe of guaranteed, 24/7 baseload power per unit. Co-locate directly with hyperscale campuses. No grid dependency. No intermittency. The ARC-100 delivers the energy density AI demands on a city-block footprint.
Learn more →Electrical Grid
Dispatchable, carbon-free generation that ramps with demand. Each ARC-100 replaces a retiring coal or gas plant with 75,000 households worth of firm capacity. No weather dependency.
Learn more →Heavy Industry
The ARC-100 generates 100MW of electrical energy and 286MW of thermal energy with an outlet temperature of 510°C providing direct superheated steam which can be increased to 850°C with topping heat for a wide range of industrial applications including chemicals, mining and petrochemical operations.
Learn more →Medical Isotopes
The fast-neutron spectrum of the ARC-100 generates high value isotopes at scale including Mo-99, Ac-225 and other critical isotopes as a byproduct of normal operation. This helps close a global supply gap.
