Abstract
This report reviews the chemistry of UO{sub 2} dissolution under conditions relevant to the disposal of used nuclear fuel in a geological vault. It provides the chemical understanding necessary for selecting the most appropriate model for estimating UO{sub 2} fuel dissolution rates in a nuclear waste disposal vault. The report briefly describes the solid-state structures of various uranium oxides; discusses the nature and mechanism of UO{sub 2} oxidation and dissolution in groundwaters; summarizes the factors affecting UO{sub 2} dissolution under oxidizing conditions; discusses the impact of various oxidants and water radiolysis on UO{sub 2} oxidation and dissolution; briefly comments on the effects of vault chemistry and secondary phase formation on the dissolution process; discusses the physical properties of UO{sub 2} that may influence the kinetics of dissolution; and describes our approach for developing a kinetic model of UO{sub 2} dissolution under oxidizing conditions.
