"We'll explode a nuke in a cavern, the walls will be melted to glass, and just poke a hole in the top, and POUR the waste inside."

I remember my history teacher in highschool talking about that.

And raising my hand and going 'But it's still nuclear waste and melted rock isn't as inert as pure glass and - '

And the teacher telling me that bureaucrats are stupid, but have money and scientists are smart, but often poor.

Someone else in the class went. "Earthquakes, wtf?"
