From 1990 to mid-2017, GNS owned and operated the Interim Storage Facilty Ahaus (TBL-A) for spent fuel elements and ILW/LLW.
The interim storage facility is located on the territory of the German town of Ahaus in the western part of the “Münsterland”, about 3 kilometres east of the town centre. The storage facility was built between 1984 and 1990. The storage building consists of two halves separated by a reception and maintenance area.

Since 2010, low- and intermediate-level radioactive waste from the operation and decommissioning of German nuclear power plants has been temporarily stored in the western half of the hall.
