The paper contains a description of a program code for the modeling the interaction of a high-temperature molten metals and zirconium dioxide concrete. The concrete is considered as a perspective refractory material to use in the ex-vessel core retention devices (core catchers). The models of thermal and chemical interactions, model of metal-inductor system coefficient are considered. The results of numerical modeling the metal melts and zirconium dioxide concrete are presented. The influence of main parameters of the problem has been investigated: power released, temperature of melting of concrete and metal, heat conductivity, emissivity, latent heat. Temperature distribution in the melt and concrete, evolution of the temperature in given points, dynamics of the heat fluxes are obtained. The comparison against experimental data are performed.
