They were absolutely not hopelessly outdated. Nuclear reactors can last 60 to 80 years.
When I checked electricity maps today Germany was emitting 17 times as much CO2 per Watt of electricity as France. That is what idiotically shutting down nuclear reactors instead of coal plants does and German environmentalists should be ashamed of themselves. German electricity is also some of the most expensive in the world and is causing companies to close plants in Germany. BASF, a major German chemical company, has implemented plant closures due to high production costs. Germany's energy policy is a disaster that has made electricity both expensive and dirty.
