The US Department of Energy's (DOE) Hanford Site in southeastern Washington State has the most diverse and largest amount of highly radioactive waste of any site in the United States. High-level radioactive waste has been stored in large underground tanks since 1944. Approximately 227,000 m{sup 3} (60 Mgal) of caustic liquids, slurries, saltcakes, and sludges have accumulated in 177 tanks. In addition, significant amounts of {sup 90}Sr and {sup 137}Cs were removed from the tank waste, converted to salts, doubly encapsulated in metal containers, and stored in water basins. A Tank Waste Remediation System has been established to safely manage these wastes and then to dispose of them. Implementing this system will require resolving several waste tank safety issues and maintaining safe storage, and then retrieving, treating, and disposing the waste onsite or packaging it for offsite disposal.
