Storage isn't that much of a problem, even in smol Europe countries.

Also it's contained in specific areas, some nerds are bound to wanna reuse what we now think of as trash/spent fuel. If it's still radioactive after it just means it radiates energy, we just didn't commercially learned how to harness it. There are ongoing studies into that too.

And radiation isn't as problematic as we are taught by media - humans lived in Chernobyl exclusion zone until death by old age, mammals there are thriving. The dangers of radiation are immediate tissue damage or thyroid cancer (again via tissue damage) if iodine isn't taken by exposed people.
