Final Reactor Design and X-10, 1942-1943. Hanford Becomes Operational, 1943-1944. Plutonium, produced in a uranium-fueled reactor (pile), was the second path taken toward achieving an atomic bomb. Design work on a full-scale plutonium production reactor began at the Met Lab in June 1942. Scientists at the Met Lab had the technical expertise to ...
Manhattan Project Roots. Development of a method to purify uranium as an integral part of the Manhattan Project led to the establishment of Ames Laboratory. After the discovery of nuclear fission in 1939, the U.S. government decided that the development of atomic energy warranted a consolidated national effort – the top-secret Manhattan ...

Private corporations, foremost among them DuPont, helped prepare weapons-grade uranium and other components needed to make the bombs. Nuclear materials were processed in reactors located in Oak Ridge, Tennessee and Hanford, Washington. At its peak, the Manhattan Project employed 130,000 Americans at thirty-seven facilities across the country.
Dunning and Harold Urey headed a Columbia team in the invention and perfection of the “gaseous diffusion” method of separating uranium isotopes, which served as the building block for the K-25 gaseous diffusion plant built during the Manhattan Project. Check out a pdf copy of the National landmark filing for Pupin Hall and a pdf draft of ...
The uranium used in the Manhattan Project came from three major sources: the Eldorado mine in northern Canada, the Shinkolobwe mine in the Belgian Congo, and mines and mill tailings in the American West. Uranium had limited industrial applications, and before the Second World War no mines existed solely for the production of uranium.
In July 1940, the U.S. Army Intelligence office denied Einstein the security clearance needed to work on the Manhattan Project. The hundreds of scientists on the project were forbidden from consulting with Einstein, because the left-leaning political activist was deemed a potential security risk.
