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.
