Only in a very limited way. As we move forward, we are quickly reaching the point where for more and more time, renewables can carry the whole grid load alone. Nuclear power plants would have to be switched off in those times. And while they can follow the load over a large part of their power output, they can't be swithed off and on again. So as the transition to renewables progresses, nuclear power plants are less and less a good counterpart. Gas plants however are. They are very quick and switching them off is possible and saves precious fuel. As the transition progresses, they should use less and less fuel as they are used more rareley and the fuel could be switched to renewable sources (bio, power2gas). The pre-war plans of the current German government included extending the gas infrastructure but with a clear ability for new installations to be also able to use H2 as it becomes available.
