There is no spectacular success of nuclear power. It provides an irrelevant fraction of overall power in the world and time and money needed to scale it up would be immense. The France's nuclear industry is an economic disaster and the EDF has been fully re-nationalized (and during the time it was semi-private there was plan to close 17 plants by 2025). The rollout of renewables works very nicely in Europe, there is no "grid failure". I am a physicist, I draw my information from looking at the underlying data, not the press.
