Dig a deep hole, put the nuclear waste in the hole, backfill with clay.
Solved.
Now I understand that different places on earth have less suitable bedrock for this storage, so I voulenteer my home municipality in Sweden as a global storage site, we have stable bedrock, the technical skill and a stable government.
As for the “we don’t have time” bullshit, I have heard that for more than ten years, it is pure bullshit, the best time to build nuclear power was ten years ago, the second best time is today.
You can yell about solar/wind as much as you ever want, but they can’t deal with the baseload as well as nuclear or coal can, coal is buring the entire planet, nuclear MIGHT at worst create a temporary inconvenience where a relatively small area has to be closed to humans. Continued use of coal will cause far, far worse harm.
