You're shutting down perfectly good old plants, ahead of schedule for no engineering derived reason. InderRealitätbleiben.

If Japan had shut down all of its plants, decommissioned them and built new plants it would have spent less money than cleaning up Fukushima. The fact that nuclear advocates keep saying newer generation power plants are safe is basically useless because they also advocate for keeping all the unsafe ones online. Tanks have modular power plants that can be replaced and serviced outside the tank. Why isn't the same true for nuclear power plants? Why not just update to the latest version instead of keeping old versions with vulnerabilities? Oh right, because they are monoliths that are a pain in the ass to upgrade. You need to rewrite them from scratch.

Which is exactly 40 years ago. Would you take the responsibility for running those things any longer?

  They are still perfectly safe for at least 20, 30 years. Nuclear plants last a really long time. Germany is just acting very dogmatic. https://www.eia.gov/todayinenergy/detail.php?id=19091 https://www.eia.gov/todayinenergy/detail.php?id=19091

  Yes, of course I would. Why throw out the baby with the bathwater. True, nuclear power plants age - whether you can extend their life or not is an engineering question for engineers. Do an inspection and come up with an answer what needs TLC. Shutting them down because standards demand is one thing. Shutting them down early because of a political games is another. Fukashima went boom, some fear mongering occurred, this helped the political careers of some people who have no idea how any of this works. Harmed some others. Consultants made money. And firms won sunset contracts. Lets not pretend otherwise.
