Doesn’t happen to solar plants.

I was sure this couldn't be true but I couldn't find anything about high temperatures shutting down solar plants.

But I did find something about a predicted grid overload during a sunny period requiring a solar plant to go offline:

Because they need more battery storage, which Europe is rapidly building.

It can't come fast enough! I have a friend who works on battery storage in Europe and it sounds like an extremely busy time for them, which I'm glad for.

Just redirect the solar power to cool the water going out of the nuclear powerplant.

"Just".

My 4th grade physics knowledge is telling me this doesn't work, because the heat energy from the water still has to go somewhere...

So yeah in the mostly probable case that reading was not involved in many of the comments, they were not shut down for a technical issue but the govt stops them from discharging the water.

All the reactor works fine and would work fine. Gov makes choice to let people hurt
