Wall thinning is one of severe problems of the secondary piping systems in nuclear power plants, so it is very essential to monitor the thickness of the pipe periodically. However, the monitoring in operation is very difficult to execute due to high temperature about to 270 degrees Celsius and thick insulating layers. This work presents a thickness monitoring method using an embedded magnetostrictive transducer which comprises an Fe-Co element, a PCB coil, and bias magnets. It was designed to be installed under insulating layers since it has considerably thin structure less than 5 mm. It can endure over 300 degrees Celsius since magnetostriction of Fe-Co occurs well during temperature region. Also a portable pulser/receiver was developed to operate the transducer. The present method was verified through experiments with high temperature specimens and shows successful results to detect the thickness of the structure.
