Manhattan Project by Goodyear Tire to encase the reactor. On 2 December 1942, a team led by Enrico Fermi initiated the first artificial self-sustaining nuclear chain reaction in an experimental reactor known as Chicago Pile-1. The point at which a reaction becomes self-sustaining became known as "going critical". Compton reported the success to Conant in Washington, D.C., by a coded phone call, saying, "The Italian navigator [Fermi] has just landed in the new world." In January 1943, Grafton's successor, Major Arthur V. Peterson, ordered Chicago Pile-1 dismantled and reassembled at Red Gate Woods, as he regarded the operation of a reactor as
Enrico Fermi Nuclear Generating Station major contributions to nuclear physics. Fermi won the 1938 Nobel Prize in Physics for his work on induced radioactivity. On October 5, 1966, Fermi 1, a prototype fast breeder reactor, suffered a partial fuel meltdown, although no radioactive material was released. After repairs it was shut down by 1972. On August 8, 2008, John McCain was taken on a 45-minute tour of the plant, becoming the first actively campaigning presidential candidate to visit a nuclear plant. The 69 MWe prototype fast breeder reactor Fermi 1 unit was under construction and development at the site from 1956 to 1963. Initial criticality
