Into Eternity is the story of the construction of Olkiluoto, a massive underground nuclear-waste repository, a structure that will have to last for 100,000 years unaided & unsupported. Bearing in mind that our oldest structures and recorded history only stretch back around 7,000 years, this will be an impressive feat.
There are two main schools of thought on the structure; to mark it to warn people to stay away, or to hide it in the hope nobody ever finds it. The first runs the risk of people misconstruing the warnings as some sort of religion and opening the structure, much as we have done with the pyramids and almost all other structures (Mayan, Egyptian, Mongolian etc etc). The second option runs the risk of being forgotten and refound at a later date with no warnings, inciting investigation.
The problem with these massive timescales lies in the fact that no human society has ever lasted the length of a single half-life and so we cannot predict the language to write warnings in, if the future pioneers even have a written language at all. So Olkiluoto is built to a depth of 7km in 1.8ga old rock in the hope that only a civilisation that will understand radiation will be able to reach this depth. This documentary made me think about nuclear power in a new light, that regardless of whether you support Nuclear or not, we still have an obligation to deal with the waste that has already been produced (somewhere in the region of 200,000 to 300,000 tonnes) for future generations. Deeply considered in a series of interviews, Into Eternity explores the concepts that surround Olkiluoto, morally, structurally and philosophically.
A truly unique and deeply-thought-provoking look at nuclear-waste and human responsibility.
