概要
The decommissioning work at Fukushima Daiichi Nuclear Power Station needs to plan based on the information of investigation in the reactor building and the environmental status such as radiation dose rate. It is necessary to develop the remote operation technologies for investigation in the reactor building, radiation measurement, removal of spent fuel and fuel debris. Hitachi Group is developing the various remote operation technologies for removal of spent fuels from the spent fuel pool and fuel debris from the reactor. For planning of removal of spent fuel from the spent fuel pool at unit No.1, we have developed and utilized the long pole-type remote investigation tools coincide with the dismantling of the existing reactor building cover. Also, we are considering some fuel removal procedure assuming a variety of environments. And furthermore, we have developed the remote investigation technologies inside the reactor or the primary containment vessel.
