Description

Behälter mit radioaktiven Körpern sind beispielsweise aus der US-A-4 950 426 bekannt. In diesem Dokument finden sich aber überwiegend nur Hinweise auf leicht oder allenfalls mittelstark strahlenden Abfall.Containers with radioactive bodies are, for example, from the US-A-4 950 426 is known. However, this document contains predominantly only indications of slight or at most moderate radiant waste.

Es ist bekannt, ein abgebranntes Kernreaktorbrennelement mit Brennstäben, die radioaktiven Kernbrennstoff in einem eine dichtverschlossene Kapsel darstellenden Hüllrohr enthalten, mit Kupfergranulat zwischen den Brennstäben zu verfüllen und anschließend um das Kernreaktorbrennelement bei hohen Temperaturen und hohem Druck einen gasdicht verschlossenen Behälter aus Kupferblech anzubringen. Dieser gasdicht verschlossene Behälter wird in einem Endlager in ein Bohrloch eingebracht, das sich in Granit befindet und das mit Bentonit-Lehm als Barriere gegen radioaktive Strahler (Radionuklide) zugefüllt wird. Das Kupfergranulat in dem Behälter aus Kupferblech soll diesem Behälter mechanische Stabilität verleihen.It is known to have a spent nuclear reactor fuel element Fuel rods that contain radioactive nuclear fuel in one contain a sealing tube which represents a capsule, to be filled with copper granulate between the fuel rods and then around the nuclear reactor fuel element at high temperatures and high pressure a gas-tight container to be made of copper sheet. This sealed gastight Container is placed in a well in a repository, that is in granite and that with bentonite clay filled as a barrier against radioactive emitters (radionuclides) becomes. The copper granulate in the copper sheet container is said to give this container mechanical stability.

Der Erfindung liegt die Aufgabe zugrunde, das Rückhaltevermögen der auf diese Weise für radioaktive Strahler (Radionuklide) gebildeten Barrieren (d.h. der Hüllrohre der Brennstäbe und des Behälters) zu verbessern.The invention has for its object the retention that way for radioactive emitters (Radionuclides) formed barriers (i.e. the cladding tubes of the Fuel rods and the container).

Diese Aufgabe löst ein erfindungsgemäß gasdicht verschlossener Behälter gemäß Patentanspruch 1, in dem mehrere abgebrannte Brennstäbe in einer Schüttung aus Zeolith und/oder Aktivkohle eingebettet sind.This object is achieved by a gas-tight closure according to the invention Container according to claim 1, in which several spent fuel rods in one Bed of zeolite and / or activated carbon are embedded.

Zeolith und Aktivkohle ab- bzw. adsorbieren - abgesehen von Edelgasen - nicht- bzw. leicht flüchtige Radionuklide und bieten damit die Möglichkeit zu drastischer Reduzierung freigesetzter Radioaktivität im Falle einer Undichtigkeit der Hüllrohre. Dies gilt insbesondere auch für radioaktives Jod, Cäsium und Strontium. Zeolith und Aktivkohle entlasten also die Barrierenfunktion des Behälters für radioaktive Strahler (Radionuklide).Absorb or adsorb zeolite and activated carbon - apart from Noble gases - non-volatile or readily volatile radionuclides and offer thus the possibility of a drastic reduction in released Radioactivity in the event of a leak in the cladding tubes. This applies in particular to radioactive iodine, cesium and strontium. Zeolite and activated carbon relieve the burden Barrier function of the container for radioactive sources (Radionuclides).

Die Schüttung aus Zeolith und/oder Aktivkohle im Behälter läßt auch genügend Leervolumen zur Aufnahme von freigewordenen Edelgasen, so daß sich im Behälter kein hoher Innendruck ausbilden kann. Trotzdem hat die Schüttung aus Zeolith und/oder Aktivkohle genügend Wärmeleitfähigkeit zum Abführen von Nachzerfallswärme aus den Brennstäben. Außerdem stellt die Schüttung eine zusätzliche Wärmekapazität im Behälter dar. Die Schüttung, insbesondere wenn sie Aktivkohle enthält, hat ferner eine gute Moderationswirkung auf Neutronen und verringert deshalb die Härte von Neutronenstrahlung, die von der radioaktiven Substanz in den Brennstäben ausgehen kann. Auch zur Abschirmung von Gammastrahlung, die von den Brennstäben ausgeht, kann die Schüttung beitragen, Schließlich stellt die Schüttung auch noch einen mechanischen Puffer für die im Behälter eingelagerten Brennstäbe dar. Diese werden durch die Schüttung vor Beschädigung beim Transport oder bei der Handhabung des Behälters zusätzlich geschützt ist. Von der Schüttung absorbierte Radionuklide begeben sich aufgrund chemischer Gesetze in Gleichgewichts zustände und verlieren dadurch ihre Neigung zur Migration, so daß die Schüttung eine Langzeitlagerung der Kapsel sicher gewährleistet.The bed of zeolite and / or activated carbon in the container also leaves enough empty volume to accommodate vacant ones Noble gases, so that there is no high internal pressure in the container can train. Nevertheless, the bed of zeolite and / or activated carbon sufficient thermal conductivity for removal of post-decay heat from the fuel rods. Also poses the fill an additional heat capacity in the container The bed, especially if it contains activated carbon, also has a good moderating effect on neutrons and therefore reduces the hardness of neutron radiation from the radioactive substance in the fuel rods can go out. Also for shielding gamma radiation from the fuel rods runs out, the bulk can contribute, finally the bed also provides a mechanical buffer for the fuel rods stored in the container. These are due to the fill from damage during transport or at the handling of the container is additionally protected. From radionuclides absorbed in the bed emanate due to chemical laws in equilibrium and lose thereby their tendency to migrate, so that the fill a Long-term storage of the capsule is guaranteed.

Gegenstand der Patentansprüche 2 bis 11 sind vorteilhafte Weiterbildungen des Behälters nach Patentanspruch 1.The subject of claims 2 to 11 are advantageous Developments of the container according to claim 1.

Die Erfindung und ihre Vorteile seien anhand der Zeichnung an zwei Ausführungsbeispielen näher erläutert:

Figur 1
zeigt schematisiert einen Querschnitt durch einen Transport- und/oder Lagerbehälter mit einem bestrahlten Kernreaktorbrennelement,
Figur 2
zeigt schematisiert im Querschnitt den Lagerbehälter nach Fig. 1 in einem Endlager.
The invention and its advantages are explained in more detail with reference to the drawing using two exemplary embodiments:

Im langgestreckten Lagerbehälter 2 nach Fig. 1 befindet sich ein Kernreaktorbrennelement 3, dessen quadratischer Umriß gestrichelt angedeutet ist. Dieses Kernreaktorbrennelement 3 weist Brennstäbe 4, und Führungsrohre 5 auf. Die Brennstäbe 4 sind mit abgebranntem Kernbrennstoff, z.B. UO2 und/oder U/PuO2, gefüllt, der Radionuklide enthält. Dieser Kernbrennstoff befindet sich jeweils in einem Hüllrohr der Brennstäbe 4, z.B. aus einer Zirkoniumlegierung, das an beiden Rohrenden jeweils mit einem Stopfen aus Zirkoniumlegierung verschlossen ist. Diese Stopfen aus Zirkoniumlegierung sind mit dem Hüllrohr gasdicht verschweißt. Die Führungsrohre 5 dienten zum Führen von Steuerstäben und sind an mindestens einem Rohrende offen. Sie enthalten keine Radionuklide.In the elongated storage container 2 according to FIG. 1 there is a nuclear reactor fuel element 3, the square outline of which is indicated by dashed lines. This nuclear reactor fuel element 3 has fuel rods 4 and guide tubes 5. The fuel rods 4 are filled with spent nuclear fuel, for example UO 2 and / or U / PuO 2 , which contains radionuclides. This nuclear fuel is in each case in a cladding tube of the fuel rods 4, for example made of a zirconium alloy, which is closed at both tube ends with a plug made of zirconium alloy. These zirconium alloy plugs are welded gas-tight to the cladding tube. The guide tubes 5 were used to guide control rods and are open at at least one tube end. They do not contain radionuclides.

Der Lagerbehälter 2 ist mit einer Schüttung 6 aus Granulat eines Zeoliths aufgefüllt. Diese Schüttung 6 braucht nicht zusammengepreßt zu sein, und mit ihr sind auch die Brennstäbe 4 und zwangsläufig die Führungsrohre 5 des Kernreaktorbrennelements 3 hinterfüllt. Der Behälter 2 besteht aus Stahl und ist an beiden Enden mit einer Stahlplatte gasdicht verschweißt.The storage container 2 is made of a granulate 6 a zeolite filled up. This bed 6 does not need to be compressed, and with it are the fuel rods 4 and inevitably the guide tubes 5 of the nuclear reactor fuel element 3 backfilled. The container 2 is made of steel and is gas-tight welded to both ends with a steel plate.

In Figur 2 ist der Behälter 2, der das Kernreaktorbrennelement 3 mit den abgebrannten Brennstäben enthält, in eine Bohrung eingesetzt, die sich beispielsweise in einem Salzstock eines Endlagers befindet. In dieser Bohrung befindet sich auf der Außenseite des Behälters 2 eine weitere Schüttung 7, die ebenfalls Granulat eines Zeoliths ist. In dieser Schüttung 7 ist der Behälter 2 vollständig eingebettet.In Figure 2 is the container 2 which is the nuclear reactor fuel element 3 with the spent fuel rods in a hole used, for example, in a salt dome a repository. Is located in this hole the outside of the container 2 a further bed 7, the is also granules of a zeolite. In this bed 7 the container 2 is completely embedded.

Besonders geeignet ist für die Schüttungen 6 und 7 Zeolith vom Typ A, vorzugsweise mindestens einer der Stoffe MgA, CaA und SrA. Ein solches Zeolith vom Typ A kann auch mit Silber dotiert sein, so daß es besonders gut radioaktives Jod zurückhält, das möglicherweise aus einem Leck im Hüllrohr eines Brennstabs 4 austritt, dann aber schon vor der Wand des Behälters 2 zurückgehalten wird, deren Rückhaltewirkung durch das Zeolith der Schüttung 6 im Behälter 2 also noch verstärkt ist. Gut geeignet für Zeolithschüttungen sind auch Chabazit und Mordenit. Besonders gut geeignet sind beispielsweise Zeolithe mit der Handelsbezeichnung "Zeolon Molecular Sieves" der 400 Series, 500 Series, 700 Series und 900 Series, die über Ionenaustausch Cs und Sr binden.The beds 6 and 7 made of zeolite in FIGS. 1 and 2 activated carbon can also be added.
