The processing and decontamination of metallic radioactive waste is one of the pressing challenges associated with the utilization of nuclear energy. One of the methods used for the treatment and purification of metallic waste is electroslag remelting. This paper discusses the modeling of the thermophysical state of the crystallizer in an electroslag remelting facility using the ANSYS FLUENT software package. A geometric model and a computational model were developed, and calculations of the crystallizer thermophysical behavior were performed under conditions corresponding to previously conducted experimental runs. The simulation results illustrate the thermal behavior of the crystallizer during the cooling of the metallic melt formed within it. The obtained results confirm the physical consistency of the adopted boundary conditions and heat transfer parameters.
