The interim storage facility is situated on the Gundremmingen nuclear power plant site and can be reached via the existing access road to the nuclear power plant 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 storage building is 104 metres long, 38 metres wide and 18 metres high and provides spaces for a maximum of 192 casks of high-level radioactive waste from the nuclear power plant. The capacity of 192 spaces is designed to meet the requirements of the nuclear power plant. 172 transport and storage containers will initially be emplaced in the interim storage facility. A later change in configuration would enable the interim storage facility to hold a total of 192 containers.
