That's not fast enough. Also, running nuclear plants at much below peak capacity is hardly efficient, increasing the cost.
Again: This is a problem no country experienced so far, because even France doesn't have that much capacity.

And that's true even assuming instant capacity adaptation. It's just not efficient to keep nuclear power at a capacity lower than their peak capacity.
You'd know if you read the link I provided.
Nuclear plants in Germany had no issues scaling up and down between 400-600MW and 1200-1400MW per reactor per day.
Now, with renewables you do have this issue. Because due to their intermittent nature you're required to both overbuild them and provide enough grid-scale storage to last for hours.

For some politically-motivated definition of efficient. Additional costs to running nuclear plants in load following mode are immaterial.
That's more than fast enough. You could see it in the graphs in the document if you bothered to read it.
Note: renewables like wind and solar are orders of magnitude slower, intermittent, and actually require grid-scale storage
France has this problem in a hidden way: They have to import power in the summer, because they DONT have that peak capacity, nuclear or otherwise. To provide that with nuclear, they would either need storage or increase the number of their nuclear plants, and probably like 50%.
