TAF-ID: an international thermodynamic database for nuclear fuels applications

Abstract : The Thermodynamics of Advanced Fuels International Database (TAF-ID) was developed using the Calphad method to provide a computational tool to perform thermodynamic calculations on nuclear fuel materials under normal and off-normal conditions. Different kinds of fuels are considered: oxide, metallic, carbide and nitride fuels. Many fission products are introduced as well as structural materials (zirconium, steel, concrete, SiC) and B4C as absorber, in order to investigate the thermochemistry of irradiated fuels and to predict their chemical interaction with the surrounding materials. The approach to develop the database and the models implemented in the database are described. Examples of models for key ternary systems are presented as well as a few examples on how this tool can be used for different kinds of applications related to the nuclear fuel behavior.
