Abstract

A method for packaging, compacting or storing spent control and absorber elements of light-water reactors for waste disposal, a device for preparing an elongated component of a spent control element, a light-water-cooled reactor and a coil of an originally elongated component are provided for storing absorber fingers or absorber sheets of spent control elements in storage containers in pressurized-water reactors or boiling-water reactors. The absorber fingers or absorber sheets are separated from the control elements. They are not cut into pieces (in which process large amounts of radioactive substances would be released), but instead they are only deformed, namely wound into coils which can be stacked in a space-saving manner in the storage containers.
