Chemval project : Application and validation of predictive computer programs describing the chemistry of radionuclides in the geosphere
CHEMVAL is an international project concerned with improving the data used to model the speciation chemistry of radionuclide migration from underground waste disposal sites. It has two main aims: - to produce a reliable database of thermodynamic equilibrium constants for use in such chemical modelling, and - to perform a series of test-case modelling exercises, based upon real site and field data, in order to verify and validate the existing tools used for simulating chemical speciation and radionuclide transport in the environment. Details are given of the work carried out by the University of Wales on the CHEMVAL project. The procedures employed for maintaining and updating the database are described. The chemical speciation modelling exercises that were carried out, involving test cases, control cases and sensitivity studies, are also presented.
