CHEMVAL is an international geochemical exercise, which aims to apply and validate predictive computer programmes describing the chemistry of radionuclides in the geosphere. The primary objective of the work carried out by the University of Manchester within the framework of CHEMVAL was to produce a comprehensive and consistent thermodynamic database for use in chemical speciation modelling of radionuclide migration. Various aspects of work on the database are discussed, including the identification and classification of the data. A comprehensive assessment of the primary literature was carried out prior to incorporation in the database. The problem of the variable quality of the primary data is addressed by assigning each datum a coded reliability index which enables the modeller to assess quickly the reliability of his results, without having to refer back to the literature. Problem areas and difficulties encountered during the database evaluation are described and recommendations for future work are presented.
