Experimental Breeder Reactor I (nonfiction)
Experimental Breeder Reactor I (EBR-I) is a decommissioned research reactor and U.S. National Historic Landmark located in the desert about 18 miles (29 km) southeast of Arco, Idaho. At 1:50 pm on December 20, 1951, it became the world's first electricity-generating nuclear power plant when it produced sufficient electricity to illuminate four 200-watt light bulbs.
It subsequently generated sufficient electricity to power its building, and continued to be used for experimental purposes until it was decommissioned in 1964.
The design purpose of EBR-I was not to produce electricity but instead to validate nuclear physics theory which suggested that a breeder reactor should be possible. In 1953, experiments revealed the reactor was producing additional fuel during fission, thus confirming the hypothesis.
On November 29, 1955, the reactor at EBR-I suffered a partial meltdown during a coolant flow test. The flow test was trying to determine the cause of unexpected reactor responses to changes in coolant flow. It was subsequently repaired for further experiments, which determined that thermal expansion of the fuel rods and the thick plates supporting the fuel rods was the cause of the unexpected reactor response.
Although EBR-I produced the first electricity available in-house, a nearby reactor plant called BORAX-III was connected to external loads, powering the nearby city of Arco, Idaho in 1955, the first time a city had been powered solely by nuclear power.
Besides generating the world's first electricity from atomic energy, EBR-I was also the world's first breeder reactor and the first to use plutonium fuel to generate electricity (see also the Clementine nuclear reactor).
