You obviously don't know anything about Germany, its people and the influence politicians have here.
Since 1986 there is an ever growing movement against nuclear power that resulted in a exit law passed 2005 by the then ruling red-green government. The vast majority backed this move. In 2010 the then ruling black-yellow government passed an exit from the exit law which was against the will of the majority of the people but obviously induced by the 4 big electricity companies that run nuclear power plants in Germany. This eventually resulted those parties that made this decision to lose the election in one of Germany's biggest state in a historic loss. For 60 years the blacks were reigning in Baden Württemberg, either alone or together with the yellow dudes. The yellow dudes aren't even part of the parliament there anymore and Baden Württemberg has a green mp now, the first in Germany ever.
Unless they want to pave the way for more green governed states it's really safe to assume that no one will even dare to change this law anymore. If anything then the exit will be sped up.
Despite massive fear mongering by the electricity lobby (higher prices, power outages) approximately 80% of Germany's population are backing the exit decision.
Some more information to help you understand the context: Whenever there are any transportations of nuclear waste through Germany there is a pretty big demonstration held, usually all along the track the waste takes and back by pretty much all kind of people, from pensioners to children, from hippies to professors ... there is pretty much everyone involved, sometimes delaying those transports for days. Quite remarkable for a country that you can pass in any direction in half a day.
The current government tried really hard to change the perception on nuclear power but it didn't help any, quite the opposite and I really doubt that they would risk this again because the chances that they will win the next election are almost non-existant already.
