Excellent Reviews! Every day, the world over, large amounts of high-level radioactive waste created by nuclear power plants is placed in interim storage, which is vulnerable to natural disasters, man-made disasters, and to 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 100,000 years as this is how long the waste remains hazardous. This documentary examines the technology designed to keep the waste safely sequestered for 100,000 years, this film also explores strategies for convincing future generations to leave the lethal material undisturbed. Filmmaker Michael Madsen directs. 2010 75 minutes.
