A Suggested Method for the Chemical Reprocessing and Purification of Th—U—O Slurry-Type Reactor Fuels

A new approach to the chemical reprocessing of contaminated Th—U—O slurry-type reactor fuels is suggested which avoids the complete dissolution of the slurry particles. The method is based on the elution of adsorbed contaminants from specially treated surface of the slurry particles using hot dilute nitric acid. In particular, the adsorption and elution properties of this type of slurry with respect to 0.004 M cerium were determined.
