A Li-7 enriched pH adjuster is essential for water quality control on PWRs. As the required Li-7 enrichment technology, we have developed the multi-channel counter-current electrophoresis (MCCCE) method. In this research, to understand the behavior of ions in the enrichment experiment, we developed a numerical simulation method of the long-time behavior of the ions based on the 3-dimensional field data of the electricity by commercial software and the flow by TPFIT-LPT. In this work, we applied it to the behavior of the ions in a simplified plate-type flow channel from the experimental one. Since the separation coefficient calculated from the simulation results of Li-7 and Li-6 ions agreed well with the experimental value, we confirmed the applicability of the method.
