    Abstract

    Various elements of conceptual model uncertainty for the clay layer are evaluated. The influence of solubility limits in the near field on the releases of radionuclides and the potential influence of complexation of actinides by fulvic acids are also studied. Stochastic calculations are performed to assess the influence of the uncertainties in the model parameters on the calculated dose rates. The computations show that the extent of the contamination in the aquifer is limited by the rediffusion of radionuclides into the host clay and the deeper clay layers.
