These tunnels are designed for 100,000 years

Onkalo, on the Finnish island of Olkiluoto, is planned to be the first geologic storage facility for high-level nuclear waste: eventually sealed for 100,000 years. I got to see inside.

Thanks to all the team from Olkiluoto, TVO and Posiva: you can find out more at http://www.posiva.fi/en/final_disposal/onkalo
