In Germany, the necessity for radioactive waste disposal has produced thirty years of studies on storage of such waste in abandoned salt mines. Two research programs on radioactive waste storage are being implemented, at the Gorleben dump site and in the Konrad mine in Salzgitter, both located in Lower Saxony. The planned dump site is to receive all types of radioactive waste, and the Konrad mine is intended as a permanent storage place for radioactive waste with negligible heat emission. The author discusses issues connected with dumping such waste, using the Konrad mine as an example.
