The Lingen 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 has been built in the immediate vicinity of the 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 interim storage facility is built on approximately 1.5 hectares of the approximately 55-hectare nuclear power plant site and is surrounded by its own security perimeter fence. The storage area covers a total area of approximately 2,000 m² of which approximately 1,200 m² is used as effective storage space. The storage building has a capacity of 125 spaces.
