The Hanford Site occupies 586 square miles (1,518 km 2) – roughly equivalent to half the total area of Rhode Island – within Benton County, Washington. [1] [2] It is a desert environment receiving less than ten inches (250 mm) of annual precipitation, covered mostly by shrub-steppe vegetation.
The building, known as the 236-Z Building, was four storeys high, with a two storey penthouse, and made from reinforced concrete. Concrete walls 10 inches (250 mm) thick permitted plutonium was as much as 20% plutonium-240 and 10% plutonium-241 content to be handled. Glove box shielding allowed for 12% plutonium-240 and 3.2% plutonium-241.
When Hanford began production, the entire world supply of plutonium totaled about 500 micrograms, enough material to form the head of a single pin. A microgram is 1/1,000,000 of a gram. A gram is ...
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 ...
B Reactor also produced plutonium for the atomic bomb dropped on Nagasaki, Japan, Aug. 9, 1945, just weeks after the Trinity Test. Japan surrendered Aug. 15, 1945, ending World War II.

[citation needed] Management of the Hanford site and Richland itself was transferred to General Electric. [6] Fears that the Soviet Union's intentions were aggressive set off the Cold War in 1947. The capacity to produce plutonium was increased beginning in 1947.
At full production, the vitrification plant’s Low Activity Waste Facility should be processing about 5,300 gallons of waste per day or producing about 23 tons of glass per day, filling 3.5 ...
