How do you convince someone to live next to a nuclear waste site?

The world’s first permanent depository for nuclear fuel waste opens later this year on Olkiluoto, a sparsely populated and lushly forested island in the Baltic Sea three hours north of Helsinki. 

Onkalo — the name means “cavity” or “cave” in Finnish — is among the most advanced facilities of its kind, designed for an unprecedented and urgent task: safely storing some of the most toxic material on Earth nearly 1,500 feet underground in what’s called a deep mined geologic repository.
