If this thing blows up, then what happens?
> fact remains that it delivers reliable, cheap, and clean electricity
That's your opinion, it's not a fact. Don't think that your opinions are facts and thus automatically what other people say is wrong. Be honest in communication with other people, so that your opinions are just opinions. You can argument in favor of your opinions, but they remain opinions and are not facts, just because YOU believe in them.
> So I suppose you have been against the closure of German reactors, right?
I'm for closing of nuclear reactors. You ignore the other things I said: nuclear power plants work only in a political environment, where they got a state-support/owned monopoly. Who do you think insures them? Who do you think sets up the regulatory environment that the get a large part of the market, who do you think is setting up the environment for waste storage. Hint: it's the government. We have extremely costly state financed clean-up operations for nuclear waste storage. These are old reactors.
To massively reduce the world co2 production, there is currently only ONE way known: massive scaling of renewable energy. The contribution of nuclear energy is neither cheap, nor clean, nor safe. It also does not scale. Nuclear energy stagnates since decades. Remember: China is bringing new coal power plants online, each week there are new ones.
Thus the industrialized countries have the responsibility (and the opportunity) to develop and share renewable energy technology, to be able be much faster in deployment, with improving technology. It's the only cost effective way known, which also can make a sizeable contribution.
