Nuclear electricity

In 1951, at 1:50 p.m., the first electricity ever generated by atomic power began flowing from the EBR-1 turbine generator when Walter Zinn and his Argonne National Laboratory staff of scientists brought EBR-1 to criticality (a controlled, self-sustaining chain reaction) with a core about the size of a football. The reactor was started up and the power gradually increased over several hours. The next day, Experimental Breeder Reactor-1 generated enough electricity to supply all the power for its own building. Additional power and core experiments were then conducted until its decommissioning in Dec 1963. Construction began in 1949, between Idaho Falls and Arco, Idaho. Today, EBR-1 is a Registered National Historic Landmark. Other reactors are at the site.Image: part of the EBR-1 control room.
