“…The furnace is designed to produce uranium and plutonium nitrides via carbon-based carbothermal reduction of uranium and plutonium dioxides in nitrogen and nitrogen-hydrogen atmosphere at temperature of 1650 ± 50 °С. The retort batch furnace design and the carbothermal synthesis process are described in (Smirnov et al 2019). Compacted powders of uranium and plutonium dioxides mixed with carbon and a binding agent (zinc stearate) are placed in rectangular open top containers (boats) inside the furnace retort.…”

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.
