The "European Pressurized Reactor (EPR)", once proclaimed to be a new impetus for the nuclear renaissance, turned out to be a disaster, characterized by safety deficiencies and cost explosions. The EPR construction sites in Flamanville, Olkiluoto and Hinkley Point C have already proved to be total failures even before their completion. Years of delays in commissioning, serious safety deficiencies and skyrocketing construction costs characterize the projects. The further construction of these reactors could be secured only by means of multi-billion Euro state rescue packages. The EPR is a clear example of the failed nuclear industry, which causes extreme costs and is thus incapable of competing with renewable energy. The current push for the development of a European fourth generation nuclear reactor will be a similar disaster to EPR’s and should therefore be stopped as soon as possible. This synopsis summarizes arguments, why a further expansion of nuclear energy should be stopped in order to avoid continuous cost explosions and billions of Euros in public debt, especially in light of significantly cheaper renewable energies.
