Description

Die Erfindung betrifft einen Transport- und/oder Lagerbehälter für bestrahlte Brennelemente, defekte Brennelemente und/oder Brennelementstäbe defekter Brennelemente, mit Behältermantel, Behälterinnenraum und darin angeordnetem Aufnahmekorb für die Brennelemente und /oder Brennelementstäbe, wobei der Aufnahmekorb über Steckverbindungen aus neutronenabsorbierenden Leichtmetallplatten zusammengefügt ist und die zusammengefügten Leichtmetallplatten Aufnahmeschächte bilden, in die Metallhülsen eingepasst sind.The invention relates to a transport and / or storage container for irradiated fuel, defective fuel and / or fuel rods defective fuel, with container shell, container interior and therein receiving basket for the fuel and / or fuel rods, wherein the receiving basket is assembled via connectors made of neutron-absorbing light metal plates and the assembled light metal plates form receiving shafts in which metal sleeves are fitted.

Bei den bekannten Transport- und/oder Lagerbehältern der vorgenannten Art ( DE 199 17 515 A1 ) dienen die Metallhülsen der Aufnahme bestrahlter Brennelemente. Defekte Brennelemente werden mit den beschriebenen Transport- und/oder Lagerbehältern regelmäßig nicht transportiert bzw. gelagert, weil diese zunächst mit einer zusätzlichen Sicherheitshülle versehen werden müssen, die in die beschriebenen Metallhülsen nicht mehr hineinpasst. Entsprechende Abänderungen des Aufnahmekorbes verursachen hohe Gestehungskosten, schränken die Ladelogistik und die Anzahl verpackbarer Brennelemente ein.In the known transport and / or storage containers of the aforementioned type ( DE 199 17 515 A1 ), the metal sleeves serve to receive irradiated fuel elements. Defective fuel elements are regularly transported or stored with the transport and / or storage containers described, because they must first be provided with an additional containment that does not fit into the metal sleeves described. Corresponding modifications of the receiving basket cause high production costs, restrict the loading logistics and the number of packable fuel elements.

Dokument EP-A-0175140 offenbart die Merkmale aus dem Oberbegriff des Patentanspruchs 1.document EP-A-0175140 discloses the features of the preamble of claim 1.

Der Erfindung liegt die Aufgabe zugrunde, einen Transport- und/oder Lagerbehälter der eingangs genannten Art so auszubilden, dass mit ihm auch die defekten Brennelemente und Brennelementstäbe defekter Brennelemente transportiert und/oder gelagert werden können, ohne das Raster des Aufnahmekorbs zu verändern.The invention has the object of providing a transport and / or storage container of the type mentioned in such a way that with him also the defective fuel and fuel rods defective fuel transported and / or can be stored without changing the grid of the receiving basket.

Die erfindungsgemäße Lösung dieser Aufgabe wird durch die Merkmals Kombination im Kennzeichnenden Teil des Patentanspruchs 1 gelöst.The inventive solution to this problem is solved by the feature combination in the characterizing part of patent claim 1.

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 the recognition that the hitherto known transport and / or storage containers for irradiated fuel rod rods can also be used for the special application mentioned when the defective fuel assemblies and / or fuel rods of defective fuel assemblies are reloaded into cans whose Coat consists of the metal sleeves. In this way, it is possible to transport intact and defective irradiated fuel assemblies and possibly also individual fuel rods defective fuel assemblies together in the container and 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 several possibilities within the scope of the invention. Thus, it is provided according to a preferred embodiment that the jacket is provided at the upper end with Wandungsausnehmungen into the gripper members of a bush manipulation device can be inserted. The sleeve itself has a bottom secured to the bottom of the shell and a lid placed on the top of the shell. This cover is preferably provided with a locking device to load and unload the can. It is also advisable to provide the bottom and the lid with at least one opening in each case Filter insert is used, in this way, the enclosed defective fuel assemblies and / or fuel rods can be dried, in particular vacuum-dried.

Der in den Figuren dargestellte Transport- und/oder Lagerbehälter dient dem Transport bzw. der Lagerung von bestrahlten Brennelementen, defekten Brennelementen und Brennelementstäben defekter Brennelemente. In seinem grundsätzlichen Aufbau besteht er aus Behältermantel 1, Behälterinnenraum 2 und darin angeordnetem Aufnahmekorb 3 für die Brennelemente und/oder Brennelementstäbe. Der Aufnahmekorb 3 ist über Steckverbindungen aus neutronenabsorbierenden Leichtmetallplatten zusammengefügt, die im Ausführungsbeispiel quadratische Aufnahmeschächte 4 bilden. In diese Aufnahmeschächte 4 sind Metallhülsen 5 eingepasst, die teilweise als Mantel einer Büchse 6 für die unmittelbare Aufnahme der defekten Brennelemente und/oder Brennelementstäbe defekter Brennelemente eingesetzt sind. Wie man aus einer vergleichenden Betrachtung der Fig. 1 und 2 entnimmt, ist der Mantel 5 am oberen Ende mit Wandungsausnehmungen 7 versehen, in die Greiferorgane einer im Einzelnen nicht dargestellten Büchsenmanipulationseinrichtung einführbar sind.The transport and / or storage container shown in the figures is used for the transport or storage of irradiated fuel assemblies, defective fuel assemblies and fuel rods of defective fuel assemblies. In its basic structure it consists of container shell 1, container interior 2 and arranged therein receiving basket 3 for the fuel and / or fuel rods. The receiving basket 3 is assembled via plug-in connections of neutron-absorbing light metal plates, which form square receiving shafts 4 in the exemplary embodiment. In this receiving shafts 4 metal sleeves 5 are fitted, which are partly used as a jacket of a sleeve 6 for the direct absorption of the defective fuel and / or fuel rods defective fuel. As can be seen from a comparative analysis of the Fig. 1 and 2 removes, the jacket 5 is provided at the upper end with Wandungsausnehmungen 7, in the gripper members of a not-shown in detail Büchsenmanipulationseinrichtung be inserted.

Den Fig. 2 und 3 wiederum entnimmt man, dass die Büchse 6 einen am unteren Ende des Mantels 5 befestigten Boden 9 und einen auf das obere Ende des Mantels 5 ausgesetzten Deckel 10 aufweist. Der Deckel 10 ist dabei mit einer Verriegelungseinrichtung 11 versehen, die in weitere Ausnehmungen 12 der Wandung einfassende Bolzen 13 aufweist. Im Übrigen sieht man in den Figuren, dass der Boden 9 und der Deckel 10 jeweils mindestens eine Öffnung 14 aufweisen, in die ein Filtereinsatz 15 eingesetzt ist.The Fig. 2 and 3 In turn, one deduces that the sleeve 6 has a base 9 fixed to the lower end of the jacket 5 and a cover 10 exposed to the upper end of the jacket 5. The cover 10 is provided with a locking device 11 which has in further recesses 12 of the wall bordering bolt 13. Incidentally, it can be seen in the figures that the bottom 9 and the cover 10 each have at least one opening 14 into which a filter insert 15 is inserted.
