Mit anderen Worten geht die Erfindung von der Erkenntnis aus, dass die bisher bekannten Transport- und/oder Lagerbehälter für bestrahlte Brennelementstäbe auch für den genannten speziellen Einsatzzweck verwendet werden können, wenn die defekten Brennelemente und/oder Brennelementstäbe defekter Brennelemente in Büchsen umgeladen werden, deren Mantel aus den Metallhülsen besteht. Auf diese Weise ist es möglich, intakte und defekte bestrahlte Brennelemente sowie gegebenenfalls auch einzelne Brennelementstäbe defekter Brennelemente gemeinsam im Behälter zu transportieren und zu lagern.In other words, the invention is based on knowledge from that the previously known transport and / or storage containers for irradiated fuel rods also for the named special purpose can be used if the defective fuel elements and / or fuel rods defective fuel elements are reloaded into cans, the Jacket consists of the metal sleeves. That way it is possible intact and defective irradiated fuel assemblies as well possibly also defective individual fuel rods Transport fuel elements together in the container and to store.

Für die weitere Ausgestaltung bestehen im Rahmen der Erfindung mehrere Möglichkeiten. So ist nach einer bevorzugten Ausführungsform vorgesehen, dass der Mantel am oberen Ende mit Wandungsausnehmungen versehen ist, in die Greiferorgane einer Büchsenmanipulationseinrichtung einführbar sind. Die Büchse selbst weist einen am unteren Ende des Mantels befestigten Boden und einen auf das obere Ende des Mantels aufgesetzten Deckel auf. Dieser Deckel ist vorzugsweise mit einer Verriegelungseinrichtung versehen, um die Büchse be- und entladen zu können. Außerdem empfiehlt es sich, den Boden und den Deckel jeweils mit zumindest einer Öffnung zu versehen, in die ein Filtereinsatz eingesetzt ist, auf diese Weise können die eingeschlossenen defekten Brennelemente und/oder Brennelementstäbe getrocknet, insbesondere vakuumgetrocknet werden.For the further embodiment, there are within the scope of the invention more options. So is after a preferred one Embodiment provided that the jacket on is provided with wall recesses in the upper end Gripper elements of a sleeve manipulation device can be inserted are. The can itself has one at the bottom of the mantle fastened bottom and one on the upper end on the cover. This lid is preferably provided with a locking device, to be able to load and unload the rifle. Moreover it is recommended to use the bottom and the lid each to provide at least one opening into which Filter insert is used, in this way the included defective fuel assemblies and / or Dried fuel rods, especially vacuum dried become.
