We developed an online monitoring device capable of performing online monitoring of wall thinning that occurs over time in the piping of thermal and nuclear power stations. We developed thin flexible probes not requiring coupling material and multi-channel monitoring equipment. This equipment can reduce the inspection period. We are performing demonstration testing for use in nuclear power stations.
The walls of piping in thermal and nuclear power stations become thin over time, making it necessary to periodically perform wall-thinning management. As the number of locations requiring inspection has reached several hundred annually, measurements are one cause of increased labor-hours during periodic inspection due to the stopping of plant operations to perform such measurements.
