Chicago Pile-1 final uranium slugs. Chicago Pile-1 Chicago Pile-1 (CP-1) was the world's first nuclear reactor. On 2 December 1942, the first human-made self-sustaining nuclear chain reaction was initiated in CP-1, during an experiment led by Enrico Fermi. The reactor's development was part of the Manhattan Project, the Allied effort to create atomic bombs during World War II. It was built by the Metallurgical Laboratory at the University of Chicago, under the west viewing stands of the original Stagg Field. Fermi described the apparatus as "a crude pile of black bricks and wooden timbers". The reactor was assembled in November 1942, by
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
