No. Cooling french nukes was never a problem. In that period France was net exporting 14GW. Cooling in general isn't a problem - some modulation is done just to save fish.
Maybe you are confusing with 2022 when half of french fleet was shut down to check for potential pipe cracks/corrosion esp in one of their reactor designs due to poor geometry. But that's unrelated to droughts
Problem isn't nuclear cooling per se. It's the designs of these nuclear reactors which expected to work with mild European weather. India and China have nuclear reactors working in desert without any cooling issues. Of course, as most of EU and west atrophied in building nuclear reactors in general, building new reactors or modifications won't be economical.
That said, cooling does have an effect on ecosystems. Not the worst energy plant impact on that regard, but still not like it's all environmental friendly.
And of course, there is the what to do with the waste dilemma. And at least with current French park, there is a dependence on the rarer kind of uranium.

A lot of NPPs in France are cooled with river water and they need to be kept at low output if the rivers are too warm.
Happens regularly. Last year’s heatwave caused a bunch of reactor shutdown across Switzerland and France - https://www.euronews.com/2025/07/02/france-and-switzerland-s...
