SIMULATION AND OPTIMIZATION OF THE ELECTRO-REDUCTION PULSED COLUMN FOR THE SEPARATION OF URANIUM AND PLUTONIUM

A computational model for separation of uranium and plutonium in an electro-reduction pulsed column was developed based on the diffusion model. The model contained steady state simulation, dynamic simulation, and optimum calculation. A numerical calculation method for this model has been proposed. W...

Description
Summary:A computational model for separation of uranium and plutonium in an electro-reduction pulsed column was developed based on the diffusion model. The model contained steady state simulation, dynamic simulation, and optimum calculation. A numerical calculation method for this model has been proposed. With this model, a calculation for an electro-reduction experiment of uranyl nitrate in a pulsed column was carried out. The calculated results were consistent with the experimental results in the literature. A comparison of the dynamic and the steady state simulations at equilibrium and an optimum calculation were also conducted. This model provides a guide for further experimental study of this process.
