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
R4 nuclear reactor the pressure vessel and containment building were subsequently used for experiments into reactor behaviour under accident conditions. The Nuclear reactor, the oil fired power station and surronding 250 hectares of land and water was acquired by Synthesis Real Estate during 2018. This reactor was built as part of the budding nuclear program for Sweden. This reactor's construction began some time during the Cold War(presumably the 1960s). The large facility was intended to bring power as well as provide plutonium for this upcoming nuclear program. Though, the construction ended in the 1960s, when the nuclear ambition of Sweden was killed. Part
