ARC - Model 100 -Advanced Small Modular Reactor

The ARC-100 is an advanced small modular nuclear reactor designed to produce up to 100 megawatts of electricity, enough to power approximately 75,000 households. Unlike conventional reactors, the ARC-100 utilizes sodium as a coolant, which allows it to operate at lower pressures, thus enhancing both safety and efficiency. One of the standout features is its ability to consume recycled spent fuel, significantly reducing waste and its hazards. The compact design occupies less than a city block, and its modular components can be transported and installed using standard commercial equipment. A hallmark of its design is passive safety, ensuring that it remains fail-safe without the need for external power or operator intervention during power outages. The ARC-100 has a core designed for a 20-year refueling cycle, using metallic uranium alloy fuel which offers excellent heat transfer and is cost-effective to produce. The reactor builds on proven technology from the EBR-II, having demonstrated robustness in sodium-cooled fast reactor operations.

Sodium as Coolant

The use of sodium instead of water as the coolant allows the reactor to operate at lower pressures, improving the efficiency and safety of the system.

Waste Recycling

When the process is approved by regulatory bodies, the ARC-100 will have the capability to consume its own recycled spent fuel limiting the amount and hazard life of fuel waste.

Small Size

The total plant size is less than a city block and its modularized components can be shipped and installed at the site using regular commercial equipment, such as barges, rail, trucks, and construction cranes.

Passive Safety

With a system that is "walk away" fail safe, the ARC-100 does not depend on extra pumps or operator intervention in the event electric power to the plant is disrupted.

Twenty Year Refueling Cycle

The proprietary core of the ARC-100 is designed to operate for 20 years without refueling.

Metal Fuel

The ARC-100 uses a metallic uranium alloy fuel, which is much simpler and cheaper to fabricate than oxide fuel with exceptional heat transfer characteristics.
