For safety and early decommissioning of Fukushima, internal survey techniques have been expected to gain an understanding of the state of Fukushima Dai-ichi Nuclear Power Station. Underwater operation and survey is considered to be necessary for vessels and buildings partially filled with retained water. As a complementary of optical instrumentation, ultrasonic underwater visualization techniques have been important for recognizing environment and obstacles for supporting remote operation. In this stud...
