An overview of Hanford site waste cleanup

Waste cleanup at the Hanford Site involves actions leading to the disposal of all radioactive and hazardous wastes, managed by the Waste Management Program, and the remediation of inactive sites and facilities, managed by the Environmental Restoration Program. The Waste Management Program consists of five missions: double-shell tank wastes, single-shell tank wastes, encapsulated cesium and strontium, solid wastes (SW), and liquid effluents. A general category of program support is also included. The Environmental Restoration Program consists of two missions: past practice units and surplus facilities. An extensive technology research, development, demonstration, testing, and evaluation (RDDT E) effort is under way. Emphasis is placed on research and development for missions where the technology to be implemented is uncertain, and on demonstration, testing, and evaluation for missions where the technology to be implemented is well developed. 2 figs., 2 tabs.
