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
Anti-nuclear movement in the United States Malibu were similar to those at Bodega Bay and were also abandoned. A small military test reactor exploded at the Stationary Low-Power Reactor Number One in Idaho Falls in January 1961, causing 3 fatalities. This was caused by a combination of dangerous reactor design plus either sabotage, operator error by experienced operators. A further partial meltdown at the Enrico Fermi Nuclear Generating Station in Michigan in 1966. In his 1963 book "Change, Hope and the Bomb", David E. Lilienthal criticized nuclear developments, particularly the nuclear industry's failure to address the nuclear waste question. He argued that it would be "...
