Abstract

The paper presents approaches that can be used to analyze the behavior of mixed nitride uranium–plutonium fuel rods during emergency situations accompanied by thermal destruction of fuel rods. The validation results based on currently available data are presented. The calculation error was estimated from the validation results. Based on the validated model, the results of a numerical study of the specific features of the breakdown of mixed nitride uranium–plutonium fuel rods are presented for accident conditions typical of reactor plants with sodium and lead coolants.

期刊介绍： High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
