Abstract

A kinetic model recently developed [1] for the radiolytically inducedoxidative dissolution of the spent fuel matrix is presented. This is basedon experimental studies on the generation and evolution of radiolyticproducts in a closed system containing fragments of PWR-fuel [2]. Theoutcome of this model is currently being integrated in the present PAexercise being prepared by SKB. The calibration of the model against variousexperimental information and its predictive capabilities for the long termperformance of the spent fuel matrix are presented.
