Graphite-moderated reactor electricity generation: There have been a number of research or test reactors built that use graphite as the moderator. The first artificial nuclear reactor, Chicago Pile-1, a graphite-moderated device that produced between 0.5 watts and 200 watts , was constructed by a team led by Enrico Fermi in 1942. The construction and testing of this reactor (an "atomic pile") was part of the Manhattan Project. This work led to the construction of the X-10 Graphite Reactor at Oak Ridge National Laboratory, which was the first nuclear reactor designed and built for continuous operation, and began operation in 1943.

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.
