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
Shutdown (nuclear reactor) coolant system is depressurized. Shutdown (nuclear reactor) In a nuclear reactor, shutdown refers to the state of the reactor when it is subcritical by at least a margin defined in the reactor's technical specifications. Further requirements for being shut down may include having the reactor control key be secured and having no fuel movements or control systems maintenance in progress. The shutdown margin is defined in terms of reactivity, frequently in units of delta-k/k (where k is taken to mean k-effective, the effective multiplication factor) or occasionally in dollars (the dollar is a unit equal to the change in reactivity
