Thermodynamic features of the processes of fluorination of spent uranium-plutonium nitride fuel of BREST reactor

摘要

Based on the results of thermodynamic analysis, we have shown that, in the course of processing of the spent uranium-plutonium nitride fuel of BREST reactors by elemental fluorine in a wide temperature range under conditions of combustion, there proceed reactions that are irreversibly shifted to the side of formation of higher uranium and plutonium fluorides. These processes are basic in the development of fluoride technology of the processing of nitride fuel.
