The Krümmel interim storage facility is located around 34 km to the south east of Hamburg on the northern bank of the River Elbe. The site belongs to Geesthacht, Krümmel in the District of Herzogtum Lauenburg (Schleswig-Holstein). The interim storage went into operation with the emplacement of the first CASTOR V/52 type cask on 14 November 2006. The licence under the Atomic Energy Act for the storage of nuclear fuels in the Krümmel interim storage facility expires 40 years after emplacement of the first cask. BGZ has been responsible for operating the Krümmel interim storage facility since 1 January 2019.
The Krümmel interim storage facility only holds high-level radioactive waste produced by the nuclear power plant itself until it is taken away for final disposal. The interim storage facility is located within the existing security perimeter fence on the site of the Krümmel nuclear power plant approximately 130 m to the south east of the Krümmel nuclear power plant reactor building. This means that CASTOR casks only need to be moved a short distance from the reactor building to the interim storage facility and that no public roads need to be used. The shallow foundation storage building is 88.0 metres long, 26.8 metres wide and 23.0 metres high and consists of a storage and reception area as well as parts of the operating area. The storage building has a capacity of 65 spaces. 770 m² of the approximately 1,350 m² storage area are available for storage purposes.
