Finland has found a solution for burying its radioactive wastes practically forever. The country’s federal authorities intend to construct a tunnel network on island of Olkiluoto off the west coast of Finland, GCR reported on the 7th of June.
These tunnels are to be filled with nuclear wastes, which will be contained there for 100,000 years – the solution that has no analogues in the world. The wastes will be put in iron sarcophaguses and into copper canisters.
According to the design, 420m tunnels will be constructed below ground and will have a capacity of 5,500 tones of radioactive waste. The repository is scheduled to be completed by 2020.
This project for the world's costliest burial ground, called the Onkalo Spent Nuclear Fuel Repository, is estimated at $4bn.
