Oak Ridge National Laboratory was completed, later renamed to "Oak Ridge National Laboratory". The site was chosen for the X-10 Graphite Reactor, used to show that plutonium can be created from enriched uranium. Enrico Fermi and his colleagues developed the world's second self-sustaining nuclear reactor after Fermi's previous experiment, the Chicago Pile-1. The X-10 was the first reactor designed for continuous operation. After the end of World War II the demand for weapons-grade plutonium fell and the reactor and the laboratory's 1000 employees were no longer involved in nuclear weapons. Instead, it was used for scientific research. In 1946 the first medical isotopes were
McMaster Nuclear Reactor confirm that there has never been a report of any nuclear material that has been lost or stolen from McMaster's reactor". McMaster Nuclear Reactor The McMaster Nuclear Reactor (MNR) is a 5MW pool-type reactor located on the campus of McMaster University, in Hamilton, Ontario, Canada. MNR began operating in April 1959, as the first university based research reactor in the Commonwealth of Nations, and remains the highest-flux reactor in a university environment in Canada to this day. The reactor consists of two connected pools; the core can be located and operated in either one. This allows the core to be
