Keywords:Glass database, high-level radioactive liquid waste (HALW), fission products (FP), CALPHAD(Calculation of Phase Diagram) method, computational phase diagram, vitrified waste, Gibbs function, modified associated solution model

Some thermodynamic properties for the vitrified medium and fission products (FPs) were acquired by the CALPHAD method. These obtained data made it possible for construction of various computational phase diagrams.
