ARC Clean Technology was founded in 2006 to take the world’s most proven advanced reactor design beyond the laboratory and into the real world, delivering the reliable, clean power required by modern industry at scale. The ARC-100 is a 100MWe sodium-cooled fast reactor refining the underlying technology of the EBR-II which operated successfully at Idaho National Laboratory for over 30 years.
Headquartered in Washington, DC with operations in Saint John, New Brunswick, ARC builds proven nuclear science into deployable infrastructure. The ARC-100 is factory-fabricated, modular, and delivers 100 MWe of baseload power for rapid deployment. That timeline matches the build schedules of data center campuses and industrial expansions.
ARC is an awardee of the U.S. Department of Energy’s Advanced Reactor Demonstration Program (ARDP) and is preparing for first US deployment to power data centers.
In Canada, ARC is working with New Brunswick Power for deployment of the ARC-100 at the Point Lepreau site and with Nucleon Energy for Alberta. In 2023, New Brunswick Power submitted a License to Prepare Site application to the Canadian Nuclear Safety Commission (CNSC) for the ARC-100 project, and in 2025 ARC successfully completed Phase 2 of the CNSC’s Vendor Design Review process. ARC is the only advanced reactor technology in Canada to have achieved both milestones.
We are not pursuing speculative technology. The ARC-100 has been prototyped and validated. Our goal is to deploy the reactor the world already knows works, at the speed and scale the energy transition demands.
