About this property

Experimental Breeder Reactor I ( EBR-I ) is a decommissioned research reactor and U.S. National Historic Landmark located in the desert about 18 miles (29 km) southeast of Arco, Idaho. It was the world's first breeder reactor. At 1:50 p.m. on December 20, 1951, it became one of the world's first electricity-generating nuclear power plants when it produced sufficient electricity to illuminate four 200-watt light bulbs. EBR-I soon generated sufficient electricity to power its building and the town of Arco, and continued to be used for experimental research until it was decommissioned in 1964.

Federal Designation

The National Register of Historic Places, administered by the National Park Service, is the United States federal government's official list of districts, sites, buildings, structures, and objects deemed worthy of preservation for their historical, architectural, archaeological, engineering, or cultural significance. Listing on the National Register recognizes a property's importance to American history but does not place restrictions on private owners; it does, however, make properties eligible for federal historic preservation tax incentives and enables consideration in federal planning decisions. National Historic Landmark designation, the highest level of federal recognition, is reserved for properties that possess exceptional national significance in the history, architecture, archaeology, engineering, or culture of the United States. This property is recorded in the National Register under reference number 66000307. It was listed on October 14, 1966.
