In Finland the world’s first permanent repository is being hewn out of solid rock – a huge system of underground tunnels – that must last 100,000 years as this is how long the waste remains hazardous.
Once the waste has been deposited and the repository is full, the facility is to be sealed off and never opened again. Or so we hope, but can we ensure that?
And how is it possible to warn our descendants of the deadly waste we left behind? How do we prevent them from thinking they have found the pyramids of our time, mystical burial grounds, hidden treasures? Which languages and signs will they understand? And if they understand, will they respect our instructions?
While gigantic monster machines dig deeper and deeper into the dark, experts above ground strive to find solutions to this crucially important radioactive waste issue to secure mankind and all species on planet Earth now and in the near and very distant future.
Captivating, wondrous and extremely frightening, this feature documentary takes viewers on a journey never seen before into the underworld and into the future.
