An investigation was conducted in which underwater robots entered the PCV basement floor area, and various sensors mounted on the robots were used to measure information about sediments and the state of damage inside the PCV. In this paper, we describe 3D mapping method of sediments by an ultrasonic sensor and the investigation results of actual plant.
