The 200 Area, located on Hanford’s Central Plateau, is where chemical processing, plutonium finishing, and defense waste management activities took place. Beginning in 1944, fuel irradiated in the 100 Area reactors was taken to the 200 Area and chemically treated to remove and refine plutonium and uranium.

These chemical separations took place in both the eastern and western portions of the 200 Area NPL site. These portions of Hanford are called 200 East and 200 West.
