Description

Implementation program of fast reactors in nuclear power engineering provides for the use of new types of nuclear fuel, in particular nitride. RFNC-VNIITF in cooperation with VNIINM develops models and codes for the simulation of physical and chemical processes for the purpose of software development and implementation of nitride mixed uranium-plutonium fuel fabrication technology. The main objective is to create software that allows you to select and optimize the process conditions. To date, developed and implemented the mathematical models of the basic processes of fuel fabrication: - grinding of powders; - carbothermal synthesis; - granulation; - pressing; - sintering tablets. Models are designed to calculate the basic characteristics of the products according to the characteristics of the starting materials and the process conditions. Also designed auxiliary thermodynamic program module that allows calculating the thermodynamic equilibrium of multicomponent and multiphase systems with different initial conditions, the thermodynamic functions of the individual reactions, allows you to work with the database of the thermodynamic properties of substances. In this work module is used for modeling systems, typical for carbothermal synthesis and sintering processes.
