No problem: French nuclear reactors need to lower output in hot summers anyway because that shit relies on river water to be cold enough for cooling. Then they buy electricity from neighboring countries.

It doesn’t “rely” on that. Regulations prevent water being backfed to the river at too much of a warm temperature. And btw France were by far Europe’s biggest energy exporter in 2023

It doesn’t “rely” on that.

France doesn’t rely on river water to cool power plants?
Where does the water come from then?

The premise is that river water isn’t cool enough to cool down NPPs. Which is false.

Ah, I see.
So the water is not too warm for cooling, it’s too warm to absorb the backfeed, which is a necessary result of the cooling process.
Which effectively still means that they can’t properly cool the plant because the river water is too warm.
