'''Experimental Breeder Reactor I''' ('''EBR-I''') is a decommissioned [[research reactor]] and [[U.S. National Historic Landmark]] located in the desert about {{convert|18|mi|km}} southeast of [[Arco, Idaho]]. It was the world's first [[breeder reactor]].<ref>{{Cite encyclopedia |title=Breeder reactor |url=https://www.britannica.com/technology/breeder-reactor |language=en |website=Encyclopedia Britannica |access-date=2017-12-31}}</ref>  At 1:50&nbsp;p.m. on December 20, 1951, it became one of the world's first electricity-generating [[nuclear power plant]]s when it produced sufficient electricity to illuminate four 200-watt [[light bulb]]s.<ref name=argonne>{{cite web |url=http://www.ne.anl.gov/About/reactors/frt.shtml |title=EBR-I (Experimental Breeder Reactor-I) |publisher=Argonne National Laboratory}}</ref><ref name=ans>{{cite web |url=http://www.ans.org/pubs/magazines/nn/docs/2001-11-2.pdf |title=Fifty years ago in December: Atomic reactor EBR-I produced first electricity |publisher=American Nuclear Society |work=Nuclear News |author=Rick Michal |date=November 2001}}</ref> 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.  The museum is open for visitors from late May until early September.{{Citation needed|reason=Is there a reason it is only open during these months?
