The 300 Area is part of the Hanford Site in the state of Washington, USA. The area was originally used for the production of fuel for nuclear reactors and for performing research on improving the production process, however most modern work being done focuses on environmental research. After a decade of demolition activities, the surplus 300 Area facilities, with the exception of the 324 Blg, have been torn down. Today, the few buildings that remain active are laboratories, workshops, and offices. It is operated by the Pacific Northwest National Laboratory.
