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. On 12 December 1942, CP-1's power output was increased to 200 W, enough to power a light bulb. For a workforce, Pegram secured the services of Columbia's football team. The first reactor built on the Argonne National Laboratory-East site, it operated from 1954-1979. President Hutchins was in no position to make an independent judgment of the hazards involved. 10.2 Pile Driving Operation 27 . [62] Between 15 September and 15 November 1942, groups under Herbert Anderson and Walter Zinn constructed 16 experimental piles under the Stagg Field stands. Chicago Pile Number One, or CP-1 for short, consisted of 40,000 graphite blocks that enclosed 19,000 pieces of uranium metal and uranium oxide fuel. Nevertheless, the scientists could not be sure they could control the reaction. [44] Its objectives were to produce reactors to convert uranium to plutonium, to find ways to chemically separate the plutonium from the uranium, and to design and build an atomic bomb. If a neutron absorber, or neutron poison, is injected at any time during this period, the reactor will shut down. The reaction rapidly halted. CP-2 stands for Chicago Pile 2 (Argonne Lab reactor). The original idea was to build a nuclear pile at a location in the Argonne Forest about 30 miles outside Chicago, but there were construction problems. [46] He proposed a schedule to achieve a controlled nuclear chain reaction by January 1943, and to have an atomic bomb by January 1945. [83], About two layers were laid per shift. At 10:37 Fermi ordered Weil to remove all but 13 feet (4.0 m) of the last control rod. The cheapest way to get from Chicago Midway Airport (MDW) to Chicago Pile-1 costs only $0, and the quickest way takes just 14 mins. We went to Dean Pegram, who was then the man who could carry out magic around the University, and we explained to him that we needed a big room. [74], Another group, under Volney C. Wilson, was responsible for instrumentation. Chicago Pile 2 (CP-2) - pictured in March 1943 - was born in early 1943, when Chicago Pile 1, the world's first nuclear reactor, was dismantled and moved to the Cook County Forest Preserve near Palos Hills. [48][52], Compton felt that having teams at Columbia University, Princeton University, the University of Chicago and the University of California was creating too much duplication and not enough collaboration, and he resolved to concentrate the work in one location. [78] The first layer placed was made up entirely of graphite blocks, with no uranium. More uranium was used, so it contained 52 short tons (47 t) of uranium and 472 short tons (428 t) of graphite. [47][48], Fermi christened his apparatus a "pile". The nearby North Stands had a pair of ice skating rinks on the ground floor, which although they were unrefrigerated, seldom melted in winter. Chicago Weather: Warming Trend On The WayCBS 2 Meteorologist Robb Ellis has the 10 p.m. forecast for Friday, Dec. 25, 2020. The stands at Stagg Field were demolished in August 1957; the site is now a National Historic Landmark and a Chicago Landmark. [109] An accident involving radium and beryllium powder caused a dangerous drop in his white blood cell count that lasted for three years. One widely circulating photo showed bricks “appearing” in Chicago on November 2. The material from the Chicago Pile, known as CP-1, includes a piece of the Graphite rods from the facility in Chicago where the first nuclear reaction was performed on December 2, 1942. When filled with uranium oxide, each weighed about 60 pounds (27 kg). i The success of Chicago Pile-1 provided the first vivid demonstration of the feasibility of the military use of nuclear energy by the Allies, and the reality of the danger that Nazi Germany could succeed in producing nuclear weapons. Unlike most subsequent nuclear reactors, it had no radiation shielding or cooling system as it operated at very low power – about one-half watt. [28][29] (Today the average number of neutrons emitted per fissioning uranium-235 nucleus is known to be about 2.4). [81][89] It contained 6 short tons (5.4 t) of uranium metal, 50 short tons (45 t) of uranium oxide and 400 short tons (360 t) of graphite, at an estimated cost of $2.7 million.
