L'énergie de la contestation : formes de désaccord et arènes du conflit sur le nucléaire en Lorraine

From the building of power plants through nuclear waste management, the nuclear energy never stops to cause disagreements. The thesis focuses on Lorraine’s case, which stepped into the French nuclear program since 1978 with Cattenom nuclear plant (in Moselle) and continues its development with the Cigéo nuclear radioactive waste disposal (in Meuse/Haute-Marne). From the scale of territories, the work shows how people try to impeach those projects. This approach examines the classic opposition between "pro" and "anti" nuclear people. To achieve this, the notion of disagreement reveals the diversity of Cattenom and Cigéo protests, which aren’t always led by ecologists. Depending on their form, disagreements have and impact on the perception of situations, actor’s behaviors, and make sense for those participating or watching through media. The thesis covers the disagreement schemes of forty years of nuclear protest in Lorraine. This protest is built around two poles: citizens- investigators’ controversies and activists occupiers’ polemics. The field work associated to the collection of media and digital documents show that actors express themselves in public arenas, which impact their action and discourses. Finally, communication evolves towards narrative forms, such as video and video games. It shows the actors’ will to tell the controversy’s past and future.
