File:Stagg Field reactor.jpg

Description
English: The first nuclear reactor was erected in 1942 in the West Stands section of Stagg Field at the University of Chicago. On December 2, 1942 a group of scientists achieved the first self-sustaining chain reaction and thereby initiated the controlled release of nuclear energy. The reactor consisted of uranium and uranium oxide lumps spaced in a cubic lattice imbedded in graphite. In 1943 it was dismantled and reassembled at the Palos Park unit of the Argonne National Laboratory.
