Nuclear chain reaction the last one called ""Perfectionnement aux charges explosives"" was the first patent for the atomic bomb and is filed as patent n°445686 by the Caisse nationale de Recherche Scientifique. In parallel, Szilárd and Enrico Fermi in New York made the same analysis. This discovery prompted the letter from Szilárd and signed by Albert Einstein to President Franklin D. Roosevelt, warning of the possibility that Nazi Germany might be attempting to build an atomic bomb. On December 2, 1942, a team led by Enrico Fermi produced the first artificial self-sustaining nuclear chain reaction with the Chicago Pile-1 (CP-1) experimental reactor in
Enrico Fermi Nuclear Generating Station a companion unit identical to Fermi 2. It was ordered in 1972 and cancelled in 1974. See DOE data page 67 and WNA Fermi 3 data. In September 2008, Detroit Edison filed an application with the Nuclear Regulatory Commission (NRC) for a Combined Construction and Operating License (COL) for a third reactor. The new unit is supposed to be built on the same site, slightly to the southwest of Fermi 2. The reactor design selected is the 1,550 MWe GE-designed passive Economic Simplified Boiling Water Reactor (ESBWR). Review of the 17,000-page application could take four years, after which construction could
