IMHO another big issue with nuclear is concentration of power. nuclear is quite stable, but not always and when it fails you suddenly loose a huge bunch of production that becomes hard to replace. (and Im not even getting into safety here)

France had to deal with a lot of issues just this year, with around 20% of their nuclear plants unoperative, which increased prices dramatically.

Solar is mostly distributed by design (and need) and failures are smaller

this one. https://www.daikin.eu/en_us/products/product.html/ekhhe-cv37.html

I have a daikin aire source water heat pump . it does not have any “smart”. it has a wire you plug into a dry contact to start it. so i plugged it to a shelly 1 and use a smart plug to monitor its energy usage

I cannot fine tune its temperature just start-stop it, but works well enough.
