Facilities at the site include machine shops, waste-handling facilities, a boiler house, and chemistry, physics, and metallurgy laboratories. The Department used the Separations Process Research Unit, a part of Knolls Atomic Power Laboratory, to develop a process for extracting plutonium and uranium from irradiated fuel. The Knolls Atomic Power Laboratory operated the facility from 1950 to 1953. Once the process was developed, the operation was transferred to Hanford, Washington. The Separations Process Research Unit facility consists primarily of two interconnected buildings.
Additional facilities consist of the tunnel area, tank farm, and waste storage areas.
