Deep geological repositories

(Video in German only)

Throughout the world, the storage of radioactive waste in rock layers deep below the earth's surface is regarded as the safest solution. In view of this, the Nuclear Energy Act calls for the use of deep geological repositories. A deep geological repository is a facility in a deep geological layer in which radioactive waste can be stored. Its purpose is to guarantee the short-term and long-term protection of human beings and the environment.

Safety is assured through the use of a number of technical and natural barriers: the waste is sealed in storage containers which are completely surrounded by backfill (technical barriers), while the dense layers of host rock form the natural barrier.
