We developed the electrolytic decontamination machine that can effectively decontaminate pipes up to the clearance level in decommissioning of NPPs. The advantage of the machine can effectively decontaminate moving electrode in pipes in a for a short time. In this report, we explain the basic characteristics of electrolytic decontamination and the performance of the machine.
