EBR-I lights four bulbs (1951)
At the same Idaho desert site, the Experimental Breeder Reactor-I produced the first usable electricity from nuclear fission. It powered four light bulbs, then the building that housed it. The reactor was a government science project, not a product.
It proved fission could generate electricity and that a reactor could breed new fuel.
EBR-I became a National Historic Landmark and anchored Idaho's role as the country's reactor proving ground.
Antares reached criticality at the same site, but as a private company on a deadline rather than a federal lab. The contrast shows how the model for building reactors has shifted.
