Sweden started building a final storage facility for spent nuclear fuel on Wednesday, only the second such site in the world, where highly radioactive waste will be stored for 100,000 years.

The whole point of doing it this way is that it doesn’t need to be maintained. Once it’s full you just fill the tunnels up (probably with dirt and/or rock) and close them off and you’re good, it’ll sit there for those 100,000 years.
No security or monitoring? No warnings about digging or mining?
