The some approaches for the numerical simulation of multicomponent molten corium behavior under severe accident in reactor are discussed. Thermal-concentration convection model taking account of phase changes in thermodynamic equilibrium approximation is considered. Results for the simplified setting are reported. Classification of approaches for the modelling of the multiphase flows is given and the some possible multifluid models are considered.
