The retort batch furnace for the carbothermal synthesis of uranium and plutonium nitrides is a component of the mixed nitride uranium-plutonium ( MNUP ) fuel Fabrication/Refabrication Module ( FRM ), a part of the Pilot Demonstration Energy Complex ( PDEC ). A  CFD  model of the furnace was built in the SolidWorks Flow Simulation code to check the feasibility of its thermophysical operating modes (heating and cooling rates, temperature of the product loaded into the furnace). The experimental data obtained from the performance tests was used to verify the developed  CFD  model and to confirm its adequacy. The relative deviation of the calculated temperature of the loaded product from the experimental data in the process of isothermal annealing does not exceed 0.7%.The temperatures of the loaded product predicted by the  CFD  model were used to justify engineering solutions for the uranium and plutonium nitrides carbothermal synthesis furnace. The  CFD  model can be used to define the furnace operation mode by selecting the gas flow rates inside and outside the retort, the heater temperature, and heating and cooling rates for the product loaded in the furnace.
