概要
Pipe blockages are caused by an accumulation of sand and rust within the drainage pipes of Hamaoka Nuclear Power Plant, and it is hoped that an efficient blockage clear ing method can be established. For these purposes, we have investigated and selected general purpose monitering equipment for the interior surfaces of pipes and blockage clearing equipment. We have also made applicability assessments using full-sized mockup equipment, the same as actual drainage pipes. Furthermore, we have tested the effe ctiveness of equipment on actual pipes blockage. The effective blockage clearing method and its application for drain pipes in Hamaoka Nuclear Power Plant its described.
