Enrico Fermi Enrico Fermi (; ; 29 September 1901 – 28 November 1954) was an Italian and naturalized-American physicist and the creator of the world's first nuclear reactor, the Chicago Pile-1. He has been called the "architect of the nuclear age" and the "architect of the atomic bomb". He was one of very few physicists to excel in both theoretical physics and experimental physics. Fermi held several patents related to the use of nuclear power, and was awarded the 1938 Nobel
R4 nuclear reactor of the plant was later used as an oil-fired plant, but the large building remains an unused structure to this day. The reactor was later used to test nuclear safety equipment, as well as the behavior of nuclear reactors. R4 nuclear reactor R4 nuclear reactor was a nuclear reactor built at Marviken and the fourth nuclear reactor built in Sweden. It was heavy water moderated and intended for the dual role of 130MWe of power generation as well as plutonium production. It had a central role in the Swedish nuclear weapon programme. During the mid 1960s, the social democratic government
