Abstract

The management of radioactive waste, particularly of High-Level Radioactive Waste (HLW) containing isotopes, whose half-life exceeds one million years, is a wicked and aporetic problem. The amount of waste increases continuously, while the question of management remains technologically and politically unsolved. Not only do the technological challenges involved exceed the horizon of scientists, but the ethical problems raised by the use of nuclear power have been neglected from the beginning. The history of nuclear power is as well a history of neglecting its consequences. No country is able to provide a suitable concept of storage for HLW. Instead, we have failing approaches: for example, decaying barrels in the Channel and the Atlantic Ocean, and in Germany two salt mines stuffed with unregistered amounts of waste on the edge of collapse.After the disaster at Fukushima Daiichi in March 2011, the German Federal Government decided for the second time to stop using nuclear power as an energy source, and on July 5th 2013, it passed a law mandating a new search for a storage site. In the beginning of 2013, an interdisciplinary project—ENTRIA—was launched to investigate options for radioactive waste management from the perspectives of the technical sciences and the humanities. ENTRIA is evaluating three possible options for storage: deep geological disposal, retrievable deep geological repository with monitoring, and permanent dry cask storage above ground. Each of the three options bears particular technological and ethical challenges.
