But where can you find such a place? In Germany people believed to found such a place in an old salt mine, now they have to get the stuff back before the mine is completely flooded with water and will contaminate the area around it. And that wasn't high radioactive waste. You need to store is from 100,000 to a million years and you need to inform people about it. Which isn't easy b/c we couldn't really understand the writings on the Pyramids in Egypt which were build just a few thousand years ago. Nuclear power is also dangerous because you can't easily tell apart if a country use it to generate power or build a bomb.
