概要

Since the accident at Fukushima Daiichi Nuclear Power Station of the Tokyo Electric Power Company, reconstruction work at Fukushima has needed to deal with high radiation environments and has demanded new technologies. This requires the development of remote-controlled robots capable of rubble removal, radiation measurement, and other technologies, as well as ways of utilizing these technologies in tandem. It is also necessary to conduct a site survey (including the visual assessment, identification of access routes, and radiation measurement), formulate a cleanup plan for decontamination and the removal of rubble, and to use remote-controlled robots for performing essential tasks. We have been developing and applying the remote-controlled robots for environmental survey, decontamination and work of concrete rubble removal at the high-dose radiation area inside the reactor buildings which contributes to the reduction of operational risk and radiation exposure. This article describes technologies that have been developed and applied for remote-controlled robot technology.
