On July 17, 1955, Arco became the first city in the world to be lit by nuclear energy! Electricity, generated by the Boiling Water Reactor III (EBR I) at the internationally renowned Department of Energy Idaho National Laboratory, was switched by local technicians to light the City of Arco for approximately 2 hours on that historic day. Arco’s Atomic Days, sponsored by the Butte County Chamber of Commerce, is held annually on the 3rd weekend of July. It is a community-wide celebration of this historic day in Arco’s history.  Come run with us and enjoy a weekend of celebration, activities, and history that Atomic Days has to offer. See the list of activities below:
