In several countries in the EU, as well as in the Brussels corridors of the European Union institutions, a vehement debate is currently taking place regarding the demand for more nuclear power. Only five years ago, this attention hardly existed. This study looks at the sudden surge in attention for nuclear energy and tries to understand the role of different actors on the side of the nuclear lobby. It investigates the case of the Netherlands, which turned from a de facto nuclear phase-out country to one where expansion of nuclear energy is currently under preparation, as well as the European Union, where a large minority of Member States have brought nuclear back to the table in many climate-related legislative debates.
