Popular Mechanics, March 1952
Making history are these four bulbs as they glow with the first electricity ever produced by atomic energy. (Experimental Breeder Reactor I)
For the first time in history, useful amounts of electricity have been produced with atomic energy. The Atomic Energy Commission announced that although the power generated was only 100 kilo-watts and the project was entirely experimental, the result is another milestone in the atomic age. Heat energy was removed from an experimental breeder reactor by a liquid metal of a type not revealed. Sufficient heat was transferred to generate steam for driving the turbine and generator. Power generation is an incidental part of the breeder-reactor experiments being conducted near Idaho Falls, Idaho, but it is providing data about the handling of liquid metals under radioactive conditions. The principal function of the breeder reactor is to convert nonfissionable material into fissionable material more rapidly than the nuclear fuel is consumed, a process that would contribute to expansion of our atomic program. It can never be used to generate large amounts of power, but it is providing information that will be valuable in designing atomic power plants of the future, say scientists at the Idaho laboratory.
Heat from the atomic breeder reactor made the steam that spun the turbine and generator shown above.
Scientists and technicians recorded their feat on the power-plant wall.
Today, Experimental Breeder Reactor 1 (EBR1) is decommissioned and has been designated as a U.S. National Historic Landmark. Located about 18 miles southeast of Arco, Idaho. At 1:50 PM, December 20, 1951, it initially produced sufficient electricity to illuminate four 200-watt light bulbs. I took the photos below during a 2010 visit to the site:
EBR-I subsequently generated sufficient electricity to power its building, and continued to be used for experimental purposes until it was decommissioned in 1964. (Wikipedia)
