Experimental Breeder Reactor No. 1 Arco, ID

On December 20, 1951, the EBR-I produced the first usable amounts of electricity created by nuclear means; in July 1963, it was the first reactor to achieve a self-sustaining chain reaction using plutonium instead of uranium as the major component in the fuel. In addition, the EBR-I was the first reactor to demonstrate the feasibility of using liquid metal at high temperatures as a reactor coolant.
