Into Eternity is a documentary about a deep geological repository for nuclear waste. The concept of long-term underground storage for radioactive waste has been explored since the 1950s. The inner part of the Russian doll-like storage canisters is to be composed of copper. Hence in the case of Onkalo it is tightly linked to experiments on copper corrosion in running groundwater flow. Application for the implementation of spent nuclear fuel repository was submitted by Posiva in 2001. The excavation itself started in 2004. With a total of four operable reactors providing 25% of the country's energy supply, Finland ranks 16th in the world nuclear power reactors country list topped by the United States (104 reactors) and France (58 reactors).
This film explores the question of preparing the site so that it is not disturbed for 100,000 years, even though no structure in human history has stayed standing for such a long period.
"Every day, the world over, large amounts of high-level radioactive waste created by nuclear power plants are placed in interim storage, which is vulnerable to natural disasters, man-made disasters, and societal changes. In Finland, the world’s first permanent repository is being hewn out of solid rock – a huge system of underground tunnels – that must last the entire period the waste remains hazardous: 100,000 years."
Once the repository waste has been deposited and 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 Giza 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?
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."
