Keywords:vitrified wastes, elution, wet process, ImPACT

To develop a wet processing technology for recovery and separation of long-lived fission products from vitrified nuclear wastes in a framework of ImPACT Program, we investigated effects of acid concentrations on elution behavior and kinetics of simulated fission products and main components of a borosilicate glass matrix.
