One might discuss prolonging the life-time of the reactors still operating and bringing back the ones switched off a few weeks ago. But this might be more difficult to do than it sounds, as their end-of-lifetime was planned long ago so they might no longer be in a state where you just could keep them running. In the grand scheme of things, it doesn't make sense to go back to nuclear power. It is afterall a very expensive technology. It is much more efficient to go full in with renewables. And nuclear power does not work well together with renewables, as it cannot be controlled fast enough.
