November 24, 2021 – Beffroi de Montrouge, France
The 9 magnitude earthquake on 11 march 2011 caused a huge tsunami coastal flooding. It led to the core melt of three reactors from the Fukushima Daiichi nuclear plant and to the loss of cooling of different spent fuel storage pools. High radioactive releases in the environment occurred, causing 160 000 people living in the Fukushima Prefecture to be evacuated and a long-term contamination in the area around the plant.
10 years after the disaster, IRSN invites the participants of this workshop to discuss the results of different research projects in the domain of Social Sciences and Humanities. These projects aimed at understanding and drawing lessons from this major accident. They were conducted by IRSN in the framework of the AGORAS Project cofounded by the French Nuclear safety and radiation protection research program.
These research projects highlight the question of developing the nuclear safety organisations capability to tackle the unpredictable during the crisis management and at the time of the design of the plants.
This conference is a free event.

Morning session – Crisis Management
9:35 – 10:45 Involvement in a hostile environment: lessons learnt form the Fukushima Daiichi accident
Olivier Isnard, Elsa Gisquet (IRSN)
Since a nuclear accident crosses organizational boundaries, abolishing the dichotomy between local and national, between immediate and distant environment, we place the notion of space at the heart of crisis management thinking. Lessons of the Fukushima accident have shown that crisis management and its unexpected dimension exists in different spaces that are themselves redefined by the dynamic of the crisis. Actors are involved in these spaces in order to tackle the hostile environment of severe accident. Based on the analyses of a sociologist and an expert who experienced this situation, the aim of the communication is to reflect on the way it is possible to support these different dimensions of commitment; whether it is a collective commitment - to continue to act, to improvise and to supply the damaged power station with resources and technical means - or an ethical commitment - which leads to risk-taking for the professionals involved. But commitment also implies receiving a counterparty in return, which should not only be declarative, but also tangible.

11:05 – 12:15 Tackling the unpredictable through crisis exercises
Elsa Gisquet, Patricia Dupuy
How can the multiple actors of the crisis prepare to act and coordinate to face unexpected situations? In this communication, social scientists and emergency preparedness and response staff will examine the construction of relevant repertoires of action to prepare to adapt and act with the means at hand, in a real crisis situation. Beside the normalization of crisis management arising through crisis exercises, we will reflect on the possibility for more complex continuing process of learning to support forms of collective action confronting the unexpected.

Afternoon session – Preventing Accidents
14:00 – 15:10 Recovering confidence over nuclear facilities robustness after the Fukushima Daiichi accident
Mathias Roger, Olivier Loiseau (IRSN)
All around the world, Fukushima accident has affected the public as well as expert’s confidence in nuclear safety and triggered a period of crisis for regulatory bodies. When the accident occurred, French nuclear industry was engaged in the process of life span extension of power plants. Within this context, the accident and the associated crisis of confidence have opened an “opportunity window” to go beyond status quo that frame risk management and to renegotiate terms and conditions to pursue reactors operation beyond 40 years. This presentation will illustrate the work done by French safety experts in the domain of seismic risks to recover confidence in nuclear facilities robustness. Based on the dialog between a sociologist and an expert who was involved in this work, we aim to show how this recovery was possible thanks to a tenuous articulation between lessons learned directly from Fukushima events and the need to prepare for the future of the nuclear industry.

15:30 – 16:40 Preventing the accident in the daily operation of plant
Nicolas Dechy, Hervé Bodineau (IRSN)
The study of major industrial accidents reveals that their development is often made possible or encouraged by deviations linked to the daily operation of the facilities, which weaken the safety barriers. A significant part of safety management aims at preventing a deterioration of the operating conditions of the installations, in particular by maintaining the conformity of the installations and the instrumentation necessary for monitoring the process. It must also ensure the detection of drifts in risk control. Maintaining a constant concern for the risk of accident is not without its own problems, such as knowing how to spot the warning signs of safety degradation. Indeed, safety is a distributed and global phenomenon, which raises issues of centralization of information and integration of points of view in large and complex systems. Moreover, while defense in depth is likely to provide margins and instill confidence, it can paradoxically authorize certain temporary deviations. In this context, several points of view (Operator, Regulator, Expert, Civil Society) can be developed on the diversity of practices that allow risk awareness to be maintained in daily operations and to detect drifts.

+ Enhanced health and safety measures
As the safety of our guests is our top priority, a layered approach to health measures will be implemented throughout the “Beffroi de Montrouge”, including required wearing of protective face masks and enhanced cleaning measures.
As the situation is constantly evolving and varies depending on your country of origin, we invite you to
consult the European Union website
to have the latest information on the conditions to enter France.
According to information available from the French government, as of the issue date of this page, a Health Pass must be presented in paper or digital format which includes a QR Code - including the EU digital COVID-19 certificate, or equivalent for non-European Union countries, which fulfills one of the following criteria :
• That a guest is fully vaccinated (with an EMA-approved vaccine):
o 7 days after the second shot for two-shot vaccines (Pfizer, Moderna, AstraZeneca);
o Four weeks after the shot for one-shot vaccines (Johnson & Johnson);
o 7 days after the shot for vaccines administered to people who have already had COVID-19 (only one dose is necessary).
• OR that a guest has been tested (PCR or Antigen) and has a negative result within the last 72 hours;
• OR for persons who have had COVID-19: the result of a positive RT-PCR or Antigen test, attesting that the individual has been infected, and that a period of time of at least 11 days and less than 6 months has passed since the test result was obtained (considered as a recovery certificate).
Guests are being asked to carry with them valid proof of identity should there be spot checks by the police to verify the name on their Health Pass.
+ Practical information
All sessions will be in French with a possibility of simultaneous translation in English.
