Keywords:nuclear reactors and nuclear facilities, inside of long medium and small diameter pipes, without cutting and without contamination diffusion, plans and current status

It was simply difficult to decontaminate the inside of long medium and small diameter pipes with a length of 20m to 100m that were contaminated during the decommissioning of nuclear reactors and nuclear facilities without cutting them. We have designed a laser device that can decontaminate the inside of these long, medium- and small-diameter pipes without cutting and without contamination diffusion. Here we report our plans and current status.
