In order to accelerate the decommissioning of TEPCO HD Fukushima Daiichi Nuclear Power Station, it is important to understand the status inside reactors and fuel debris. In this research project, as fundamental research phase, we are developping the remote inspection method such as camera SfM (Structure from Motion), ultrasonic measurement techniques, LIBS (Laser-Induced Breakdown Spectroscopy) on a robot arm for monitoring the structure status in the reactor and the distribution of materials by a long-articulated robot arm with controlling the position and posture of the robot arm hand. In this presentation, the results of the evaluation tests and the future prospects of the remote inspection method will be reported.
