After touring the Idaho National Laboratory, visit Experimental Breeder Reactor No. 1 (EBR-I) and Atomic Museum, which tells the story of the world’s first nuclear power plant. Colorful, interactive displays also tell the story of EBR-I’s sibling, Experimental Breeder Reactor No. 2 (EBR-II), which once powered much of the site and operated with a novel closed fuel cycle. The museum also has two aircraft nuclear propulsion prototypes, a reactor control room, remote handling devices for radioactive materials, radiation detection equipment, and more. You can walk through the museum using the self-guided tour instructions or take a guided tour.
