As "A historic heritage related to maintenance technology and a cultural heritage of humankind with the aim of encouraging the development, dissemination and contribution to society of Maintenology." the automatic ultrasonic flaw detection machine for reactor vessel (A-UT Machine) was recognized as the first heritage. The A-UT machine was used for the first time in the world for the inspection of reactor vessels of PWR nuclear power plants in 1995. Since then, improvements have been made to improve the accu...

Periodical measurement of pipe wall thickness for power plant is performed with manual UT during outage. Furthermore, periodical water level measurement is performed during plant operation by using UT sensor because there is a possibility that the gas-void in the piping may adversely affects the components. There is necessary to carry out the monitoring during plant operation in order to realize the improvement of those managements. However, the continuous monitoring during plant operation is difficult...
