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 Power Plant (Italy) Enrico Fermi Nuclear Power Plant (Italy) Enrico Fermi Nuclear Power Plant was a nuclear power plant at Trino (often referred to as ‘Trino Vercellese’, meaning ‘Trino in the Province of Vercelli’), in north-west Italy. Consisting of one 260 megawatt pressurized water reactor (PWR) from the vendor Westinghouse Electric Corporation, it operated from 1964 until 1990. Trino was in 1964 the third ever commercially operated PWR worldwide, and it had the second highest megawatt-capacity of them. It was closed down following the Italian nuclear power referendum, 1987. The experimental enrichment plant, EUREX, near the power plant, was closed down in 1984.
