Those are a very small number of reactors and not affecting in anyway the grid, it's totally planned, you do get clickbait article every year though. By the way, they are only being stopped by regulation as well, not any technical problem.

Additionally, renewables had more severe issues at the moment from the heatwaves, above 25 degrees, solar panel outputs drops a lot and generally there's not much wind either during this kind of weather to compensate.

I don't know why people keep bringing this up, it's an non-issue and it's never been one.

What do you think regulation is for?

We were breaking a lot of records with renewable energy here in Germany lately...

Those regulations are there to save fishes, they're not related to nuclear plants, coal plants also have the same issue. That's to save wildlife. If you don't care about fishes, the plant technically works.

Since there's a need for maintenance anyway and less demand, that's not worth killing the fishes with warmer water.

A nuclear power plant does not work 'technically', if it harms the environment.

I mean we're going in circles here, it's not needed to start those plants in summer anyway so...

Sure, you can always import German electricity.

The reason those plants are not needed (as I said multiple times they are not) is because you have 50% share of electricity heating. And you obviously don't need any heating in summer...
