Abstract

The simulation code for the pyrochemical processing of spent nuclear fuels was developed to analyze experimental data, to predict experimental results, and to propose adequate conditions and processes. The <u>S</u>imulation code for <u>P</u>yrochemical <u>R</u>eprocessing (SPR) is based on calculations of chemical equilibrium and electrochemical reactions. The code also includes the calculations of the current-potential distribution between the electrodes. Some calculations were made to simulate the experimental results on the electro-codeposition process of UO<sub>2</sub> and PuO<sub>2</sub>. The phenomena of the redox reactions between Pu<sup>4+</sup> and Pu<sup>3+</sup> ions and those between Fe<sup>3+</sup> and Fe<sup>2+</sup> ions were theoretically analyzed; these redox reactions cause the low current efficiency in the electrocodeposition process. The calculated current-potential distribution around the cathode corresponds to the observed distribution of the oxide deposited on the cathode.
