Plutonium could be produced by irradiating uranium-238 in a nuclear reactor, [4] but developing and building a reactor was a task for the Manhattan Project physicists. The task for the chemists was to develop a process to separate plutonium from the other fission products produced in the reactor, to do so on an industrial scale at a time when plutonium could be produced only in microscopic ...
Plutonium manufactured at the site was used in the first atomic bomb, which was tested in the Trinity nuclear test, and in the Fat Man bomb used in the bombing of Nagasaki. During the Cold War , the project expanded to include nine nuclear reactors and five large plutonium processing complexes, which produced plutonium for most of the more than ...
During the Cold War, the Hanford Site facilities were expanded to include nine nuclear reactors and five large plutonium processing complexes that produced plutonium for most of the more than 60,000 weapons built for the US nuclear arsenal. After sufficient plutonium had been produced, the production reactors were shut down between 1964 and 1971.
Trace amounts of plutonium-238, plutonium-239, plutonium-240, and plutonium-244 can be found in nature. Small traces of plutonium-239, a few parts per trillion , and its decay products are naturally found in some concentrated ores of uranium, [ 54 ] such as the natural nuclear fission reactor in Oklo , Gabon .

During its lifetime, the plant manufactured 1,000 to 2,000 pits per year. [131] Rocky Flats became the primary plutonium pit production site in the United States. Los Alamos National Laboratory would continue to be used as a pit R&D facility from 1949 to 2013. [129] The Hanford Site also produced plutonium pits from 1949 to 1965. [129] [31]
The government has revealed it sent half a ton of weapons-grade plutonium from S. Carolina to a site in Nevada months ago despite the state's protests. Nevada officials had no clue the federal ...
Watchdogs are raising new concerns about legacy contamination in Los Alamos, the birthplace of the atomic bomb and home to a renewed effort to manufacture key components for nuclear weapons. A ...
