ARC is a clean energy technology company developing the ARC-100, an advanced small modular reactor offering safe, reliable, and economical power. Built on the EBR-II, which ran for over 30 years at Idaho National Laboratory, the ARC-100 is factory-fabricated and modular, delivering firm baseload power ideally matched for data center and industrial users. It's a liquid sodium fast reactor that theoreticlly enables a future closed fuel cycle with 99% fuel utilization. In any loss-of-power or loss-of-cooling scenario, the reactor shuts itself down through natural physics: thermal expansion of the fuel and coolant inserts negative reactivity, and natural convection of the sodium removes decay heat indefinitely. ARC is a U.S. Department of Energy Advanced Reactor Demonstration Program awardee advancing first U.S. deployment, with additional international deployment underway in Canada and Türkiye.
