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 "We Almost Lost Detroit", was written by local Detroit newsman John Grant Fuller (subtitled "This Is Not A Novel" to point out that it was not a work of fiction). The song "We Almost Lost Detroit", by Gil Scott-Heron is also about the Fermi 1 meltdown. Fermi 2 is a 1,198 MWe General Electric boiling water reactor owned and operated by DTE Energy. Plans to build were announced in July 1968. Initial criticality was achieved in July 1985, and full commercial operation commenced on January 23, 1988. The reactor vessel holds 764 fuel assemblies and 185 control rods which modulate
