D Reactor was one of the three original reactors built in World War II. The reactor next to it is known as DR, or the D Replacement. DR Reactor was built in 1949-50 because Hanford scientists thought D Reactor was going to fail and they wanted to take advantage of the D Reactor pumphouse and other support buildings. However, they solved D Reactor's problems and the two reactors operated side-by-side until the mid-1960s. The Control Room of D Reactor is housed in the Smithsonian Museum, but is currently not on display.
Bechtel Hanford, Inc. is working to place D and DR Reactors into safe storage, or the "cocooned" state. Cleanup of soil in the 100-D Area began in 1996. Since then over 600,000 tons of contaminated soil has been moved away from the nearby Columbia River to the Environmental Restoration Disposal Facility. A private, commercial subcontractor under Bechtel's management is performing the work.
