Title: Precipitate hydrolysis process for the removal of organic compounds from nuclear waste slurries

Abstract

This pattern discusses a process for removing organic compounds from a nuclear waste slurry comprising reacting a mixture of radioactive waste precipitate slurry and an acid in the presence of a catalytically effective amount of a copper presence of a catalytically effective amount of a copper (II) catalyst whereby the organic compounds in the precipitate slurry are hydrolyzed to form volatile organic compounds which are separated from the reacting mixture. The resulting waste slurry, containing less than 10 percent of the original organic compounds, is subsequently blended with high level radioactive sludge and transferred to a vitrification facility for processing into borosilicate glass for long-term storage.
