The Fukushima Daiichi accident raises a fundamental question: Can science and technology prevent the inevitability of serious accidents, especially those with low probabilities and high consequences? This question reminds us of a longstanding challenge with the trans-sciences, originally addressed by Alvin Weinberg well before the Three Mile Island and Chernobyl accidents. This paper, revisiting Weinberg's issue, aims at gaining insights from the accident with a special emphasis on the socio-technical or human behavioral aspects lying behind the accident's causes. In particular, an innovative method for managing the challenge is explored referring to behavioral science approaches for a decision-making process on risk management; such as managing human behavioral risks with information asymmetry, seeking a rational consensus with communicative action, and pursuing procedural rationality through interactions with the outer environment. In short, this paper describes the emerging needs for Japan to transform its national safety management institutions so that these might be based on interactive communication with parties inside and outside Japan.

For the safety assessment of high level waste disposal system, it is important to understand the migration behaviors of actinides in the near- or far-field. Although the importance of migration of actinides which form the colloids has been pointed out recently, the migration behaviors of colloids are not fully understood. In this study, the migration behaviors of colloids were investigated experimentally by column method. In the experiments, quartz powder was used as the solid. Ferric hydrous oxide colloids were prepared as the real colloids and neptunium(V) formed Np(V)-Fe(III) pseudocolloids by sorption. Some fractions of the colloids eluted with the eluting solution. Also observed were strongly retarded fractions. Non-negligible fractions were found to migrate faster than the eluting solution. These migration characteristics were qualitatively understood in this work.
