Abstract
This paper takes up the cases of the release of ALPS-treated water into the sea and the recycling of radioactively contaminated soil, which have been planned and implemented by administrative agencies as part of the concept of "coexistence of reconstruction and decommissioning" after the Fukushima nuclear power plant accident. There are structural problems and damage mechanisms (including "structural violence") common to both ALPS-treated water and contaminated soil. This research found and clarified common points in the logical structure and flaws in the risk decision-making process leading to the planning and implementation of each countermeasure by administrative agencies (such as the fact that the implementation plan is not based on concrete and clear laws). In particular, in this paper, the four elements of "regulations on grounds," "availability of risk communication," "types of uncertainty," and "With or Without risk trade-off," are important criteria for judgment. Because this paper also points out that these four factors may be the root causes of the two essential structural problems surrounding the Fukushima nuclear accident. In addition, this paper presents the problems of safety and security administration in Japan and a new perspective of legal policy studies in this case.
