Nuclear reactor lower than had previously been thought. The memorandum was a product of the MAUD Committee, which was working on the UK atomic bomb project, known as Tube Alloys, later to be subsumed within the Manhattan Project. Eventually, the first artificial nuclear reactor, Chicago Pile-1, was constructed at the University of Chicago, by a team led by Italian physicist Enrico Fermi, in late 1942. By this time, the program had been pressured for a year by U.S. entry into the war. The Chicago Pile achieved criticality on 2 December 1942 at 3:25 PM. The reactor support structure was made of wood,
Enrico Fermi Nuclear Generating Station of threats to public health and the environment. The groups have filed 14 contentions with the NRC, claiming that a new plant would pose "radioactive, toxic and thermal impacts on Lake Erie's vulnerable western basin." In May 2015, the Nuclear Regulatory Commission approved a combined construction and operating license for Fermi 3, but DTE Energy stated there were no plans for construction at that time. The Nuclear Regulatory Commission's 2010 estimate of the risk each year of an earthquake intense enough to cause core damage to the reactor at Fermi was 1 in 238,095 making it the 88th least likely
