In the decommissioning process of the Fukushima Daiichi Nuclear Power Plant of the Tokyo Electric Power Company, Incorporated (TEPCO), it is necessary to investigate the leakage area of coolant and so on. We have focused on ultrasonic measurement as an investigation method to supplement optical measurement methods such as cameras.In this study, we have developed and verified a measurement system using ultrasonic velocity distribution measurement and ultrasonic environmental measurement to measure the velocity distribution in a wide area and to estimate the leakage point in unknown underwater environment, aiming to apply the measurement method to a robot for the investigation in the reactor during the decommissioning work process.
