Glock, France (of all countries) seems to be doing quite well with nuclear power. They are far and away the country with the highest percentage of their energy coming from nuclear plants, 75% (the US is only 19%). Slovakia and The Chocolate Poodles of Belgium are practically tied for 2nd, at a little over 2/3 of France's %age of nuclear to overall energy.
