You asked for it.
Nuclear Power is a many facetted issue - especially in Germany.
Politics:
Backing out of nuclear power was a declared goal of the Green party since its foundation.
Claiming to have accomplished this goal was one of their biggest annoucments in their last campaign.
I doubt, that the Greens can claim political success here. As Sean Lindstrom has already pointed out, this Stade reactor has reached the end of its life cycle. The Greens have nagotiated no more, than to get fixed dates from the industry, when a certain reactor will go off the grid. Like stating, that reactor will be switched off in 2024 or 2025, whereas before, it was: it will go off in the '20ies.
More important: the actual decision, that no new nuclear power plants will be built, was already made in the late seventies or early eighties. Whoever did this (maybe I can find out), is the real father of the German "Atomausstieg".
Energy Technology
About nuclear power being the cleanest form of energy production: This is wrong - and not only IMO.
Nuclear power leaves behind highly toxic waste, that will bother us for millenia. Imagine: if mankind would have had nuclear plants back when we invented writing, half of that waste would still be around. OTOH, we could still go on with nuclear power for a few years. After all, does it really matter if we have to handle 500,000 or 1,000,000 tons of highly radioactive material for 10,000 years.
Clean power is something like geothermal energy or wave energy, that only uses the resources for building such a facility. Wind energy is also clean, but has a smalish and unstable output. Solar cells are not a good means for clean enery production. They are expansive, they are sensitive against damage, and maybe not very healthy in production. Fusion energy could also be a clean energy.
The most dirty energy comes from mineral oil and coal. And I don't mean particle emissions like smoke or soot which lead to deseases like pseudo-krupp. I also don't mean SO2 and the acid rain phenomenon of the 1980s. I am talking of CO2 and global warming.
Radioactive isitopes have a decay time up about 10,000 years. But how long is the decay time of CO2? In fact, it does not really decay, it might be stored in sediment rocks, water, live-stock or oil though.
Risks
San Pellegrino already said that, while the risk of a plant going blowing up is rather low, the potential damage is huge. Counting in millions of people.
I doubt that any insurance company would sign a contract that would hold em financially liable for the possible damage done. At least, insurance fees would be unbearable high, rendering nuclear power economically unsound.
Anyway, I wouldn't want to be the one security officer, that has technically approved of a certain facility and then it goes boom.
On the other hand:
Is there a money figure counting the risk of global warming? The risks of raising CO2 levels in our atmosphere is probably less understood than the ill effects of radiation. The possible danger that comes with global warming, is perhaps even higher. The danger is global and will not be locally confined. People in hot lattitudes will face drought and famine.
Oceania will be drowned. (The only gaining regions might be Siberia and Canada, maybe Patagonia ...)
What is worse: millions of people dying a slow death through radiation or millions of people having their soil/life-base destroyed?)
(It feels strange to make comparisons about the misery of millions of people.

)
Mental dispostion in Germany
Most Germans think abandoning nuclear power is a good idea, regardless of where they stand on the political spectrum.
Why is that so? A few possible reasons, but please note, that I can't really look into the heads of my countryman. I might be far off.
<smart-ass mode:>
"nuclear power" in Germany is often called "atomic power", ingnoring the physical fact, that burning oil set free energy from an atomic reaction, while splitting atoms is happening at the nucleus level.
<over>
Anything, that has the word Atom sticked to it is suspicious to some German minds. Perhaps this is because for quite a while, it looked like, come nuclear armagaddon/WWIII, we Germans would be right in the middle of the frying pan.
Interestingly, the Greens gathered about the time when Pershing cruise-missiles were stationed in Germany. "The Atom" became the symbol for all that was considered negative: atomic bombs and war, big companies and capitalism, big science and technocracy.
Personally
Nuclear power plants are not a good solution. We should abandon them asap.
Coal and oil power plants are an even worse solution. We should abandon them even before the nuclear plants.
