So, if your fathers started coal plants, you close them, stop paying for them and can forget about them. this is not at all the case if your fathers started nuclear plants, not only do you have to pay, your children have to pay, all their lives, and all your grandchildren, and so on.
What bugs me is the tendency of proponents to pretend that the decision is no biggie. It is a biggie. At least understand that, then we can have a rational discussion about it!
Energy storage solutions and infrastructure for generating synthesized fuels (hydrogen and others) will require investments, but those investments will be a gift to the future. We will bear the burden of building the infrastructure now, but future generations will benefit from what we have built.
Nuclear is the opposite, we get the benefits and the future gets the burden.
Nuclear costs are way higher than anyone has ever accounted for and they are kicked to future generations. This is a fact and we can do better.
The right thing to do is surely to spend now on tech that continues to pay dividends in the future. Maybe we ourselves won't see the benefits directly in our wallets but the future will.
I suspect you don't live in e.g. Tuvalu? Or in a country experiencing desertification like Spain?
My issue is that this statement is wrong, though. All the greenhouse gas from coal that was burned in the past, and all the coal we're still burning, will still be around and is still going to slowly bake the planet we live on for the next millenia [1].
Effectively, coal emissions are only considered this way because, after we stop producing, we stop seeing the smokestacks and we forget that the byproducts are still there. This is also true for most other pollution sources: industrial sites with heavy metal pollution don't magically clean themselves when the factory closes. WW1 battle areas are still deeply polluted and some are still unfit for agriculture. "Eternal" chemicals are never going back to the oil well. And, for us technologists, ewaste does not magically disappear [2].
It's really maddening that some people develop an acute perception that radioactive waste is "forever", but somehow fail to understand that the same is true for a very large part of the waste we create now, for which nature hasn't (over millions of years) evolved organisms able to eat them.

So at least 15 years of effort to get one plant online during which time the country will continue to pump CO2 to the tune of 70% coal in their electricity mix. CO2 that will, as you say, continue to bake the earth. Nuclear is a terrible choice for decarbonization.
