Spent UO2-fuel Dissolution. Tentative Modelling of Experimental Apparent Solubilities

  • J Bruno (a1), R S Forsyth (a2) and L O Werme (a3)

Abstract

Experimentally measured concentrations in spent UO2-fuel leachates are reported for uranium and plutonium for contact times ranging from 14 days to 2 years at different pH. The experimental results for uranium clearly indicated saturation. This interpretation was supported by comparison with theoretical solubilities, calculated using a modified SOLGASWATER program. The calculated solubilities were found to agree well with the experimentally determined concentrations.
