For the aging management of reactor pool in the Nuclear Safety Research Reactor (NSRR) of Japan Atomic Energy Agency (IAEA), the inspection of pool lining, which is made of Aluminum, was decided to be an important item. Therefore, we develop a device which is controlled remotely and measures the thickness of the pool lining by non-destructive method using ultrasonic wave. Test operation and test measurement using this device have been executed successfully in the mock-up and in the reactor pool....

In the decommissioning measures of Fukushima Daiichi Nuclear Power plant (1F), it is important to ensure the thermal stability of the reactor and the whole system by the cooling system in order to prevent criticality of fuel and fuel debris. However, wall thinning is concerned due to the corrosion in the piping of the cooling system. In order to maintain the safety of the system, it is necessary to manage the piping thinning. In this study, the EMAT thickness monitoring system, which can measure thickne...

In this study, we propose a novel EMAT-ECT multi sensor aiming at advanced structural health monitoring. For the purpose, proto-type EMAT-ECT multi-sensor was developed and their functions both as ECT and EMAT prove were evaluated. Experimental results of pulse ECT using the EMAT-ECT multi-sensor showed that the pr oposed sensor has a capability of detection and sizing of flaws. Experimental results of EMAT evaluation using the EMAT-ECT multi-sensor showed that ultrasoni c wave was transmitted by EMAT-ECT ...
