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
Enrico Fermi High School town-wide high school enrollment of 1,500 students. Proposed use of the vacated building include moving the middle school to the Enrico Fermi location or renovating the building as a town library/community center. The Enrico Fermi name was used as the name of the new STEAM wing of the expanded and renovated Enfield High School. In 2016, Enrico Fermi High School closed, and its students attend Enfield High School. The school is named after Italian physicist Enrico Fermi. A site for the school was purchased in February 1968 and a ground-breaking ceremony took place on September 14, 1968. The school opened
