At a time when Germany, Italy, Spain and Switzerland have decided to move away from atomic energy and focus on renewable energy, France - the most nuclear-powered country in the world, with 70% of its electricity produced by its reactors - is planning to invest in new EPRs. Is this choice really compatible with the ecological transition? Although nuclear power plants do not emit CO2, their dismantling at the end of their life generates pollution of another kind: exponential quantities of contaminated waste, the reuse of which remains hypothetical and the storage of which is highly problematic. Not to mention the risk of disaster, as at Chernobyl or Fukushima.
