the water doesn't have to be that warm before it fails to cool your nuclear reactor down effectively. This is already happening in france https://www.theguardian.com/business/2022/aug/03/edf-to-reduce-nuclear-power-output-as-french-river-temperatures-rise

Did you even read your own source...

This is a legal requirement, not a technical one.
The water won't ever be too hot to cool down the reactors. How hot do you think the nuclear reactors are, 40°?

"Legal" requirement sounds like you don't really care if you'd kill thousands if not millions of fish by giving them a heat stroke.
Power plants need to cool down their hot cooling water to harmless levels before releasing it back into the lakes or rivers. That is what those giant cooling towers are for. But on hot summer days, their efficiency is greatly reduced and that limits the plant's thermal waste output and thus production capacity. And that is why they should be paired with solar energy to fill the gap on such hot days.

Given that this law has been repealed this summer during the worst drought of recent history without any consequences, it's fair to say this piece of legislation was unnecessarily cautious.
In any cases that's not related to what OP said about water being too hot to cool down the reactors, with a lot of confidence.

you can't just boil a river...what are you talking about? You can't just destroy every river that a nuclear plant is on, the fact that the water is too hot to return to the river...means its too hot.

Dude, I won't let you move goalposts. You literally said that:

Stop making excuses and be grateful you learnt basic thermodynamics today.
And stop parroting this shit anymore.
