Enrico Fermi of his life, Fermi questioned his faith in society at large to make wise choices about nuclear technology. He said: Fermi underwent an exploratory operation in Billings Memorial Hospital on 9 October 1954, after which he returned home. 50 days later, Fermi died at age 53 of stomach cancer in his home in Chicago. His memorial service was held at the University of Chicago chapel, where colleagues, Samuel K. Allison, Emilio Segrè, and Herbert L. Anderson spoke, mourning the loss of one of the world's "most brilliant and productive physicists." His body was interred at Oak Woods Cemetery. Fermi received
Nuclear reactor 8 December 1953. This diplomacy led to the dissemination of reactor technology to U.S. institutions and worldwide. The first nuclear power plant built for civil purposes was the AM-1 Obninsk Nuclear Power Plant, launched on 27 June 1954 in the Soviet Union. It produced around 5 MW (electrical). After World War II, the U.S. military sought other uses for nuclear reactor technology. Research by the Army and the Air Force never came to fruition; however, the U.S. Navy succeeded when they steamed the USS "Nautilus" (SSN-571) on nuclear power 17 January 1955.
