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 core Nuclear reactor core A nuclear reactor core is the portion of a nuclear reactor containing the nuclear fuel components where the nuclear reactions take place and the heat is generated. Typically, the fuel will be low-enriched uranium contained in thousands of individual fuel pins. The core also contains structural components, the means to both moderate the neutrons and control the reaction, and the means to transfer the heat from the fuel to where it is required, outside the core. Inside the core of a typical pressurized water reactor or boiling water reactor are nuclear fuel rods equivalent to the diameter
