Mathematical Modelling of MNUP-Fuel Production by the Carbothermic Synthesis Process for Fast Neutron Reactors

Abstract

The studying of the obtaining nitride fuel technology by the carbothermic synthesis is a result of this work. The developed model of the carbothermic synthesis furnace for mixed nitride uranium-plutonium fuel obtaining allows getting the most important parameters of the facility, such as the composition of the gas atmosphere, pressure, temperature and composition of furnace feed and obtained products. In MATLAB, the numerical modelling of the carbothermic synthesis process was used. This model allows user to monitor the effect of construction parameters of the furnace and control system parameters.
