Between the time of the discovery of nuclear fission in early 1939 and the end of 1946, approximately 90 “nuclear piles” were constructed in six countries. These devices ranged from simple graphite columns containing neutron sources but no uranium to structures as complex as the water-cooled 250-MW plutonium production reactors built at Hanford, Washington. This paper reviews and compares the properties of these piles.
