Reducing radiotoxicity in the long run

摘要

Stockpiles of spent nuclear fuel and weapons material are growing worldwide. So far, the only long-term strategy seriously considered is geological repository for several hundred thousand years. Transmutation is an option significantly reducing the time during which repositories have to be sealed, simplifying the task of protecting future generations from the radioactive remnants of our civilisation. This paper gives an overview of motives and priorities, and describes the main technique suggested for transmutation of nuclear waste.
