A number of European Union Member States are either engaged in, or are formulating post-closure radiological safety assessments to demonstrate the viability of their chosen waste disposal options. These assessments depend on reliable estimates of radionuclide migration from the repository to the surface environment which, in turn, are derived from computer based models of containment release, transport and retardation. The verification and, where possible, validation of such models have formed the basis of the international Chemval project. The second phase of Chemval considered the following six discrete modelling and experimental programmes:
modelling the effects of elevated temperatures on groundwater chemistry;
modelling the effects of high ionic strength on speciation and solubility;
characterization and modelling of sorption processes;
modelling of complexation by high molecular weight organics;
simulation of trace metal co-precipitation;
modelling of coupled chemical transport processes. This report provides an overview of work carried out in these six technical areas the resulted obtained.
