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 clearing meth od can be established. For these purposes, we have investigated and selected general purpose monitering equipment for the interior surfaces of pipes and blockage clearing equipm ent. We have also made applicability assessments using full-sized mockup equipment, the same as actual drainage pipes. Furthermore, we have introduced improvements, tested the effectiveness of equipment on actual pipes blockage, and finally arrived at an effective blockage clearing method.
