Former rock-salt mine 10 km to the south-east of Wolfenbüttel built for the trial ultimate waste disposal of low and medium active waste. 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. The storage licence for radioactive waste expired in 1978.
