Actually they do. The US has been collecting money from nuclear plants for disposal for literally 50 years.

In fact, they have an absurd amount of money since this money has been collecting interest. It it political deadlock and systematic incompetence that prevents the solving of this problem.

And in addition, long term storage is an incredibly dumb solution for most of this 'waste' and is a fundamentally flawed policy that again, is simply systematic incompetence.

> I still have not met anyone who is prepared to have nuclear waste stored in their "neighborhood"

Disagree, put it in my garden. I don't care. You can leave it there for the next 100 years. Seriously, its not hard to store, it just stands there and does nothing and is 100% harmless unless you come up with some plot of Armageddon style logic.

> So it accumulates on-site, where there was no real planned long-term storage accommodation.

Its accumulates on-site because of systematic incompetence in the federal government.

> and the cost of nuclear accidents

The likely hood of such accidents is incredibly small, even if you assume 100 years of nuclear power for 100% of the population the chance of really series accidents is very low. And even lower if we consider next generation nuclear.

Solar and wind should also be transparent in the fact they require fossil fuels to fill in gaps in production. Thus, they do not represent a solution to climate change but merely delay it. Thus the cost of solar and wind includes the cost of climate disaster.

Long term storage is actually trivial, just requires actually storing it.

Counterintuitively, best way is glassing it and dumping it on the abyssal plane in the sea.

This controls the temperature and acts as a radiation shield and there's more a hundred times more life on the surface than in the abyss. Also, no humans who get prissy about 1 in 100 chances of cancer than animals don't fare about. The ocean's also big enough that a your case corroding and some material being dissolved and spreading in the water is irrelevant (unless all your nuclear waste you ever dump manages to escape and spread throughout the ocean rather than just sit in a sullen pile you'll be under EPA limits).
