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 Public Schools. In November 2012, a town-wide referendum to appropriate $103 million for additions and renovations to Enfield High School overwhelmingly passed by a 2:1 margin. As a result of the consolidation Enrico Fermi High School is planned to close, resulting in yearly savings of $2 million, which would pay for bonding for the renovations and additions to Enfield High School. The State of Connecticut also will provide more than 70% reimbursement for construction to Enfield High School, as well. Students from Enrico Fermi will move into the expanded high school after construction is finished in 2016-2017, with an expected
