Enrico Fermi and moved to the Argonne Woods site. There Fermi directed experiments on nuclear reactions, revelling in the opportunities provided by the reactor's abundant production of free neutrons. The laboratory soon branched out from physics and engineering into using the reactor for biological and medical research. Initially, Argonne was run by Fermi as part of the University of Chicago, but it became a separate entity with Fermi as its director in May 1944. When the air-cooled X-10 Graphite Reactor at Oak Ridge went critical on 4 November 1943, Fermi was on hand just in case something went wrong. The technicians woke
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
