抄録

This article focuses on the future of the 1F decommissioning and extraction of fuel debris at Fukushima Daiichi Nuclear Power Plant (1F). To succeed to 1F accident in and lessons from the nuclear disaster to future generations is important factor to create the future style of the 1F decommissioning. Japan’s government and TEPCO officially decide “the Medium-and-Long term Road Map” which sate to finish the 1F decommissioning in 30–40 years later from achievement of the cold shutdown state of 1F, December 16th, 2011. In addition, the government of Fukushima Prefecture requested the greenfield of 1F onsite by total takeoff and outside the prefecture export of the debris. However, the prefectural plan lacks in objective grounds from 1F accident in the future called greenfield of 1F onsite and the 1F decommissioning in 30–40 years after the accident. This article reexamines a way of thinking assuming “extraction of fuel debris,” and it is necessary to review social value of 1F from a point of view to succeed to Fukushima nuclear plant accident and a lesson of the nuclear disaster to future generations, and to develop. To that end, this paper examines the way of the 1F decommissioning after considering a technical aspect and the social side, and it is demanded to show various choices of the future style of the 1F decommissioning by the talks with local communities.
