AbstractFeedback from industrial accidents is provided by various state or even international, institutions, and lessons learned can be controversial. However, there has been little research into organizational learning at the international level. This article helps to fill the gap through an in‐depth review of official reports of the Fukushima Daiichi accident published shortly after the event. We present a new method to analyze the arguments contained in these voluminous documents. Taking an intertextual perspective, the method focuses on the accident narratives, their rationale, and links between "facts," "causes," and "recommendations." The aim is to evaluate how the findings of the various reports are consistent with (or contradict) "institutionalized knowledge," and identify the social representations that underpin them. We find that although the scientific controversy surrounding the results of the various inquiries reflects different ethical perspectives, they are integrated into the same utopian ideal. The involvement of multiple actors in this controversy raises questions about the public construction of epistemic authority, and we highlight the special status given to the International Atomic Energy Agency in this regard.

International audience ; The Investigation Committee on the Accident at the Fukushima Nuclear Power Stations established by the Japanese government received testimony from Masao Yoshida, the Fukushima Dai Ichi plant's Director. During the hearing, Yoshida recounted the events he experienced between 11 and 15 March 2011 (Guarnieri et al., 2015; Guarnieri et al., 2016). He appears as a character in a narrative that describes the extreme situation that he and his workers faced at the plant. This testimony is an unprecedented source of knowledge, as it is the first time a first-hand account from a key manager in a nuclear accident has been made public. The transcript is an opportunity to undertake an analysis of Yoshida's self-representation and examine the extreme situation through his eyes (Afrouss and Portelli, 2016). The analysis must also challenge classical explanations of the behaviour of collectives of engineers faced with a nuclear accident. This study requires a qualitative approach of Yoshida's testimony. This article outlines the methodological steps and precautions to be followed for such an analysis. It begins with a definition of coping and highlights its relevance to the Fukushima Dai Ichi accident. The second part assesses the benefits and limitations of qualitative research, and how it can be used in social science. Finally, the third part outlines methodological steps to analyse coping in Yoshida's narrative, while not neglecting the constraints of the approach.

National audience ; Tout est affaire de représentations. Le nucléaire n'échappe pas à ce constat. La notion de représentation recouvre ainsi l'ensemble des opinions, des croyances, des mythes qui sont produits et partagés par les membres d'un groupe, à partir d'un objet ou d'un système particulier. Ceux-ci peuvent concerner des enjeux forts et se trouver au centre d'une controverse, comme c'est le cas pour le nucléaire. L'analyse des représentations du nucléaire se justifie donc pleinement du fait de l'impact déterminant qu'elles ont sur le débat public, et la prise de décision politique. Les sources de la connaissance concernent dès lors des domaines aussi divers que la peinture, la photographie, la littérature, les articles et les dessins de presse, la publicité, les documents audio-visuels, et parmi ces derniers les films.

National audience All is a case of representations. Nuclear power does not escape this. The concept of representation thus covers all opinions, beliefs and myths which are produced and shared by the members of a group, on the basis of a particular object or system. These may concern major issues and be at the centre of controversy, as is the case for nuclear. The analysis of nuclear representations is therefore fully justified by the decisive impact they have on public debate and political decision-making. The sources of knowledge therefore concern areas as diverse as painting, photography, literature, press articles and drawings, advertising, audiovisual material, and films. ; National audience Tout est affaire de représentations.

International audience ; The mythology surrounding atomic power, which makes reference to its omnipotent energy or devastating catastrophic fire, has, since the 1950s fed the collective imagination and public debate in nuclearised societies. Although it can be assumed these debates have little in common with the operational realities of managers, the recent accident at the Fukushima nuclear power plant has shown that in many countries the debate on the withdrawal of nuclear power may lead to political decisions that have an impact on the entire population. The decommissioning of many operational plants (whether because nuclear power is being withdrawn, or because plants have become obsolete) has had an impact on the representations shared by actors in these organizations. Decommissioning operations have the effect of creating a tension between ideas of "deconstruction" and those of production. In this special phase of the plant's life cycle, interactions between actors play a key role in the construction of a shared system of representations, which is based on both a new organizational culture and a shared safety culture. These shared representations are at the origin of a cognitive consensus that must facilitate action and decision-making within organizations. This article is a historical study of representations of nuclear energy in France from the post-war period to the modern day. It first highlights the strength of myths and representations found in the design and construction phases of nuclear technology. The second part of this article shows how myths and representations affect decisions that are taken during the decommissioning of facilities. Finally, the third part of this analysis describes the consequences of these systems of representation on the morale of actors involved in decommissioning and the construction of a shared decommissioning culture.

This CRC research paper of MINES ParisTech is setting the scene for an ambitious study programme to study films (documentaries, fictions, advertisements, etc.) that deal with civil nuclear in France and internationally. The ambition is to analyse the myths and representations conveyed by these works on a controversial technology. This report is made up of five contributions which present very briefly ongoing work and which prepare for future results which will be the subject of more elaborate publications. The first is the testimony of Aurélien Portelli, a historian of science and technology, who explains and motivates the interests in film research. The second is a quick, but not exhaustive, panorama of the films that have marked the history of both civilian and military nuclear since the 1970s. The third is the report by The Land of Hope, a film produced by Sono Sion in 2012, which discusses the consequences of a nuclear accident on the inhabitants of a small city in Japan. The fourth illustrates the documentary film, taking the example of one of them, produced in 2013, which deals with the issue of decommissioning of nuclear power plants. Finally, the latest contribution provides a more elaborate analysis of the Grand Central film of Rebecca Zlotowski, presented at the Cannes Festival in 2013 and released in the rooms at the end of August 2013. ; Ce papier de recherche du CRC de MINES ParisTech entrouvre la voie d'un ambitieux programme d'étude visant à étudier les films (documentaires, fictions, publicités.) qui traitent du nucléaire civil en France et à l'international.
