Operation was terminated on 28 February 1943, and the pile was dismantled and moved to Site A in the Argonne Forest, now known as Red Gate Woods. It was selected after reassurances from Fermi that the probability of an accident was minimal. Historique . La pile nécessitait une énorme quantité de graphite et d'uranium. While a 25 feet (7.6 m) cube-shaped balloon was somewhat unusual, the Manhattan Project's high priority rating ensured prompt delivery with no questions asked. Cette pile fut conçue à Chicago dans le cadre du Projet Manhattan visant à doter les États-Unis de la bombe atomique durant la Seconde Guerre mondiale. The reactor's development was part of the Manhattan Project, the Allied effort to create atomic bombs during World War II. With this check on the uranium neutrons removed, the pile was able to achieve a sustained chain reaction for twenty-eight minutes. In February 1943, the reactor was dismantled and moved to Red Gate Woods, where it was reconstructed, shielded, and renamed Chicago Pile-2. The graphite was organized in layers in a 24-foot-square frame of timbers. The site of Chicago Pile-1 was designated a National Historic Landmark in 1965 and added to the National Register of Historic Places a year later. An abandoned rackets court underneath Stagg Field in the middle of the University of Chicago campus was chosen as the test site for the experiment. 1. He used cadmium rods to control the movement of uranium neutrons in the pile, awaiting the right time to release this control and allow the neutrons to generate an exponential chain reaction on their own.
