> Finland is also unusually blessed with tons and tons of hydropower potential which functions both as a battery as well as power generation.

Where did you get that idea from? This isn't Norway; we don't have any mountains. The country is mostly flat and most of the suitable locations already have a hydropower plant since the 1970s.

I am very pessimistic about the economics of nuclear power but Finland is basically the best case scenario for it.

Everywhere gets zero sun at night.

And at high latitudes, the night can be very long. And even when the sun does appear for a bit, it doesn't provide a lot of energy.

And you might want to ask the Fins how they feel about nuclear power: around two thirds of the population are for it as well as pretty much the entire political establishment, including the Green Party.

Last year, we had (depending on location) 0 to 25 hours of sunlight total in the entire month of December.

Low sun angle plus very heavy cloud cover means that even midday looks like a gloomy sunset.
