Electrochemical treatment of liquid nuclear wastes

OSTI ID:183516
Large quantities of highly radioactive waste have been generated throughout the Department of Energy complex over the past 50 years as a result of the production of special nuclear materials for defense and space programs. These wastes have been stored in underground tanks. Some of the tanks have developed cracks that have allowed waste to leak out of the primary tank. Many of the tanks are operating beyond their design life. Processes are being developed to remove the waste from the storage tanks and permanently dispose of it in engineered wasteforms. The bulk of the radioactivity will be concentrated into approximately 1% of the total waste volume and vitrified. The highly radioactive borosilicate glass wasteform will be placed in the federal repository. The remaining waste, which still contains low concentrations of radioactivity, will be incorporated into a low-level wasteform (e.g., cement, glass, ceramic, polymer, etc.) and placed in a near surface facility at the DOE site. Electrochemical treatment of liquid wastes is being evaluated to destroy organic compounds that impact radionuclide separations processes, and to destroy and remove hazardous species in the waste.
