The plutonium used in the first atomic weapon (the Trinity Device) was processed at the Hanford Reservation site in Washington State. The uranium used in the first actual bomb (Little Man, dropped on Hiroshima), was refined at Oak Ridge, Tennessee.
The references I have state Oralloy is 93.5% U235. Oralloy (Oak Ridge Alloy) was used in US Uranium atomic bombs as the fissile material. However they also say that any enrichment 20% U235 or higher is fissile and could be used to make a bomb, it would require a higher critical mass to work though. One source I have states that early Soviet Uranium atomic bombs used ~97% U235, but the US felt this level of enrichment to be unnecessary and excessively expensive.
Atomic fission is the process in which large atoms break apart, releasing large amounts of energy and smaller atoms. The smaller atoms are called fission products. The Oak Ridge scientists proved that element 61 was present in fission products of uranium. They named it promethium, after the Greek god Prometheus.

The uranium enrichment facilty was at Oak Ridge.
Oak Ridge, Tennessee was established as the production site for the Manhattan Project that developed the atomic bomb during World War II. Oak Ridge's nicknames include the Secret City.
Oak Ridge was where the atomic bomb, which was used against Japan, was built. To this day, Oak Ridge continues energy research, earning it the name "The Energy Capital of the World".
The bombs were not actually built at Oak Ridge. Oak Ridge produced the uranium for the first bomb in 1943-45. The bombs were assembled at Los Alamos, New Mexico. There was another facility at Hanford, Washington also producing fisslie material for the second bomb. Oak Ridge did not exist in 1941, it was empty farmland. Within two years there was a secret city of over thirty thousand inhabitants engaged in working on the project, though few understood what they were working on.
The main thing Oak Ridge did was uranium enrichment. But they also built and operated the X-10 reactor a prototype for the plutonium production reactors later built at Hanford.
The nuclear material used to make the bombs was from Oak Ridge TN
Research and production took place at more than 30 sites but most of the work was performed at Oak Ridge, Tennessee.
The atomic bomb was developed under the name of the Manhattan project and researched/ built in Oak Ridge (Tennessee), Hanford (Washington), and Los Alamos (New Mexico).
The uranium enrichment plants were built at Oak Ridge, TN and powered by cheap electricity generated by the Tennessee Valley Authority.
The atomic bomb was created in Los Alamos, New Mexico. many people may think that it was made in New York because the project behind the building of the atomic bomb was called the Manhattan Project. it is called this because it is named after the location of Columbia University that held much of the early research for the nuclear program. Today there is a museum of the atomic bomb in Los Alamos, New Mexico where you can visit and learn more about the atomic bomb.
