Numerical simulation of processes affecting the speciation, solubility and migration of radioactive contaminants is an integral part of radiological assessment procedures. The results of chemical equilibrium modelling are primarily dependent on the thermodynamic data employed and the need for standards, particularly in the case of assessment work, is clear. At the inception of Chemval, significant and largely unexplained differences were found among thermodynamic compilations in use at leading European laboratories. For this reason, a decision was made to provide a common database against which results produced using other listings could be compared. At the end of the Chemval project (1987-90) Version 4.0 was released, which contained some unreviewed data. This report summarizes the subsequent development of the Chemval thermodynamic database, the criteria employed for data selection and the contents of Version 6.0, issued to participants on completion of the Chemval 2 project, (1990-94).
