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...

Online pipe thickness monitoring sensors, EMAT, Thin-film UT sensor and FLEXDRY UTM were installed to Unit4 spent fuel pool cooling system of Fukushima No.1 Power Plant. Pipe wall thinning data and ultrasonic waveform were recorded in a control PC near the pipe. EMAT can be controlled by remote PC in a office far from No4 Unit through local area network. The measured pipe wall thickness value by FLEXDRY UTM are parallel with results of conventional UM sensor well. Starting of online monitoring of Thin-...
