Abstract
We have been studying a dry surface decontamination technology using a low-pressure arc, characterized by features such as less secondary waste. In this report, we investigated the decontamination performance of a low-pressure arc for pipe wastes. A pipe-shaped test piece with corrosion product film containing Co-60 on its inner surface was selected. As a result, the Co-60 removal ratio for the pipe test piece was found to be more than 90 percent. Thus we clarified the possibility of applying low-pressure arc decontamination technology to pipe wastes.
