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. Electricity had earlier been generated by a nuclear reactor on September 3, 1948 at the X-10 Graphite Reactor in Oak Ridge, Tennessee. EBR-I subsequently generated sufficient electricity to power its building, and continued to be used for experimental purposes until it was decommissioned in 1964. The museum is open for visitors from late May until early September.

  • Very interesting exhibit with hands on activities. Close to the main road so it is quick and easy access. They have free self guided tours or you can usually have some one walk you through. It is interesting to see 39 inches thick of glass that were used to keep the workers safe from the hot radiation. They have a mechanical hands exhibit you can try, but some people have been rough with it and only one out of the two were available.
  • Very accessible piece of history. You can self guide a tour or follow a group with a knowledgeable guide. Lots of hands on exhibits as well as actual older used equipment. Good for younger kids as well as adults. This can take a long time if you want to go in depth.
