Former rock-salt mine 10 km to the south-east of Wolfenbüttel, Germany. Built for the trial ultimate waste disposal of low and medium active waste, the disposal facility operated between 1968 and 1978, when the storage licence for radioactive waste expired. More than 120,000 barrels equal to around 24,000 m3 of low active waste have been stored here. A special storage chamber for medium active waste holds 1,289 barrels of 200 l capacity. Of the decommissioning options investigated since 2009 (complete backfilling, waste relocation, waste retrieval), retrieval was considered to be the preferred option. According to the current schedule, retrieval will not start before 2033. Current activities include stabilising the galleries and performing 3D seismic measurements.
