Experimental Breeder Reactor-I

Have you ever seen a nuclear reactor? Ever wonder how electricity is generated from nuclear energy? Satisfy your curiosity by visiting the Experimental Breeder Reactor No. 1 (EBR-I) Atomic Museum, located on U.S. Highway 20/26 between Idaho Falls and Arco.


Butte County, Idaho 83213

(208) 526-0050

The facility, a National Historic Landmark where usable electricity was first generated from nuclear energy in 1951, is open to the public from Memorial Day weekend through Labor Day weekend, seven days a week from 9 a.m. to 5 p.m. Admission is free. It's the only place in America you can see four nuclear reactors including two aircraft nuclear propulsion prototypes, a reactor control room, remote handling devices for radioactive materials, radiation detection equipment, and much more.

New in 2011 are colorful, interactive displays that tell the story of EBR-I's sibling, Experimental Breeder Reactor No. 2 (EBR-II), the reactor that once powered much of the site, operated with a novel closed fuel cycle and demonstrated its inherent safety. You can walk through the museum using the self-guided tour instructions, or take a guided tour with one of the summer season tour guides.
