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
EPR (nuclear reactor) In October 2017 the date was pushed back to the beginning of 2019, and in June 2018 to September 2019 due to testing delays. In November 2018 a further delay of four months was announced: regular electricity generation is due to start in January 2020. First concrete was poured for the demonstration EPR reactor at the Flamanville Nuclear Power Plant on 6 December 2007. As the name implies this will be the third nuclear reactor on the Flamanville site and the second instance of an EPR being built. Electrical output will be 1630 MWe (net). The project was planned to
