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.

Studies of ELM heat load, SOL flow and carbon erosion from existing Tokamak experiments, and projections for ITER

Asakura, Nobuyuki; Loarte, A.*; Porter, G.*; Philipps, V.*; Lipschultz, B.*; Kallenbach, A.*; Matthews, G.*; Federici, G.*; Kukushkin, A.*; Mahdavi, A.*; et al.

Three important physics issues for the ITER divertor design and operation are summarized based on the experimental and numerical work from multi-machine database (JET, JT-60U, ASDEX Upgrade, DIII-D, Alcator C-Mod and TEXTOR). (i) The energy load associated with Type-I ELMs is of great concern for the lifetime of the ITER divertor target. In order to understand the physics base of the scaling models, the ELM heat and particle transport to the divertor is investigated. Convective transport during ELMs plays an important role in heat transport to the divertor. (ii) Determination of the SOL flow pattern and the driving mechanism has progressed experimentally and numerically. Influences of the drift effects on the SOL and divertor plasma transport were discussed. (iii) Characteristics of chemical yield at two different deposited carbon surfaces, i.e. erosion- and redeposition-dominated areas, have been studied. Progress of understanding the chemical erosion is reviewed.

Fission mass division and topology of potential energy surface

Iwamoto, Akira; M$"o$ller, P.*; Madland, D. G.*; Sierk, A. J.*

AIP Conference Proceedings 597, p.243 - 248, 2001/00

We present calculations of fission potential energy surface based on Strutinsky's prescription for realistic shape parameterization of the fissioning nuclei. It involves 5 shape parameters from which we obtain 5-dimensional potential energy surface of more than 2.5 million points. The analysis of the saddle point was performed without any approximation and we obtained the following understanding of the fission process. (1) Most of the actinide nuclei have the lowest two saddle points, one is mass-symmetric and the other is mass-asymmetric. (2) The relative height of these two saddles depends on the fissioning nucleus and experimentally observed mass division mode was well understood from the properties of the lowest saddle point. (3) Bimodal feature of Fm isotopes was well understood from the analysis of the saddle points. (4) Degree of the mass asymmetry of the most probable mass division was well understood from the potential energy surface.
