Rising River Temperatures Threaten Paris's Water-Based Building Cooling Network (wired.com) 12
Networks of pipes and heat exchangers can transfer excess heat from buildings into nearby bodies of water -- but as the world warms, the cooling potential of some water courses is now diminishing, Wired reports. Paris's district cooling network, which pipes Seine river water to cool 800 buildings including the Louvre Museum, faces diminishing returns as climate change warms water temperatures. The system achieves coefficients of performance between 4 and 15 -- significantly higher than conventional air conditioning -- by transferring building heat through heat exchangers to the river. The Seine briefly exceeded 27C this summer, approaching the 30C regulatory limit for returned water.
The network currently spans 100 kilometers of pipes and will expand to 245 kilometers by 2042 to serve 3,000 buildings. Similar installations operate in Toronto using lake water from 83-meter depths and at Cornell University drawing 4C water from Lake Cayuga at 76 meters. Rotterdam and other cities are developing comparable systems as cooling demand rises.

Let's make all the water warmer! (Score:2)
I'm sure there won't be knock-off impacts of things like this (the example provided is heating the Seine to 30C from 27C).
Aquatic life has to love a good hot bath as much as I do!
The oceans appear to have a new average high area the last three years:

Aquatic life in the Seine? That's a funny one.
Are you ignorant? There's an abundance of aquatic life there. Those turds floating in it are literally swarmed with bacteria.

They will have to import power again because they have to ramp down the reactors. Again.

Of course anyone interested in the actual Capacity Factor of nuclear energy can look at the stats for the reactors of their choosing, since it is all very well documented and likely much more accurate than some guy on the internet.

Thanks for providing cites to prove the OP's point. France's capacity factor has remained unchanged for two decades and yet their actual nuclear energy production has varied greatly in the past 10 years due to the issue the OP mentioned. In fact only last year it looks like of a 63GWe capacity which should produce 552TWh at a 100% factor and yet they achieved 364TWh which is 66%.
Oooof that is rough, that's like having the power off for almost half a year.

But if you mean are there similar systems upstream in the Seine that make the water arriving at Paris warmer - all I can say is I searched for a minute and didn't find any, and it would be odd not to mention that as the source of incoming water being warmer in the story.

And this is a perfect example of this.
One more time, if our leaders will continue ignoring the truth and forcing business as usual to continue, then the trajectory we on
will continue to lead to global socio-economic collase, climate breakdown and our extinction.
Collapse is already in motion , weve about 5-15 years to go and only a 5% chance of changing course.
This civilisation is toast.
