THEREDA (Thermodynamic Reference Database) is a joint project collectively planned and executed since 2006 by German and Swiss research institutions which work in the field of final disposal of radioactive waste.


The THEREDA project is dedicated to the creation of a comprehensive, internally consistent thermodynamic reference database. It provides thermodynamic data (including equilibrium constants) and Pitzer interaction coefficients which in conjunction with suitable codes allow for the calculation of solubilities of radio-toxic and chemical-toxic elements in electrolyte solutions up to high concentrations. The database is used for the geochemical modelling of processes in the near- and far-field of different host rock types, which are envisaged as potential sites for final repositories in Germany.


Registered users have access (free of charge) to the different releases of the database and to all references, from which the released data sets were created, via
