The plants would need refueling and a big safety check and overhaul, which would take them offline at pretty much exactly the time where they would be the most useful. The only way to make them useful for this situation would be to skip the safety check. And everything the last few years has been done under the assumption that they will shut down, this is not an easy decision to reverse on the spot.

And for energy generation we can fall back to coal, which is easier and quicker to reactivate than nuclear energy. Not nice in terms of CO2, but the most practical solution right now.
