Description

Vorrichtung zum Nachweis von schadhaften Brennelementen in Kernreaktoren Die Erfindung betrifft eine Vorrichtung zum Nachweis von schadhaftenBrennelementen in heterogenen Kernreaktoren, bestehend aus einem labyrinthartig ausgebildeten Adsorptionskörper zur Adsorption der Spaltprodukte, welcher herausnehmbar am Austritt eines jeden Brennelementkanals angeordnet ist und nach der Herausnahme aus dem Reaktorkern auf Radioaktivität überprüft wird.Device for the detection of defective fuel elements in nuclear reactors The invention relates to a device for detecting defective fuel elements in heterogeneous nuclear reactors, consisting of a labyrinth-like adsorption body for adsorption of the fission products, which can be removed at the outlet of each Fuel channel is arranged and after removal from the reactor core Radioactivity is checked.

Die bekannten Vorrichtungen dieser Art sind in materialmäßiger und räumlicher Hinsicht so aufwendig, daß der wirtschaftliche Gesamtwirkungsgrad der Reaktoranlage beeinträchtigt wird.The known devices of this type are in terms of material and spatial terms so expensive that the overall economic efficiency of the Reactor plant is impaired.

Gemäß der Erfindung werden Vorrichtungen der eingangs erwähnten Art dadurch grundsätzlich verbessert, daß der Adsorptionskörper jalousieartig ausgebildet ist. Die Adsorptionskörperjalousien können in Abhängigkeit von einer oder mehreren Betriebsgrößen des Reaktors selbsttätig verstellbar sein.According to the invention, devices of the type mentioned at the beginning fundamentally improved by the fact that the adsorption body is designed in the manner of a louvre is. The adsorption body louvres can be depending on one or more Operating parameters of the reactor can be adjusted automatically.

In ' der Zeichnung ist ein Ausführungsbeispiel dargestellt. Sie zeigt einen Schnitt durch den oberen Teil einer Brennstoffkassette.In ' the drawing, an embodiment is shown. It shows a section through the upper part of a fuel assembly.

Der Adsorptionskörper 1 ist als Verschlußkörper in dem Kopf 2 der Kassette 3 eingesetzt. Mit 4 ist eine Greifstelle bezeichnet. Die Teile 5 dienen zum Festhalten des Adsorptionskörpers 1 in dem Kassettenkopf. Der labyrinthartige Adsorptionskörper 1 besteht beispielsweise aus Sintennaterial. Der Adsorptionskörper 1 ist jalousieartig ausgebildet. Dadurch kann eine Veränderung des Durchtrittsquerschnittes für das Kühlmittel in Abhängigkeit von einer oder mehreren Betriebsgrößen der Reaktoranlage gegebenenfalls selbsttätig erfolgen.The adsorption body 1 is used as a closure body in the head 2 of the cassette 3 . 4 with a gripping point is designated. The parts 5 serve to hold the adsorption body 1 in the cassette head. The labyrinth-like adsorption body 1 consists, for example, of sintered material. The adsorption body 1 is designed in the manner of a louvre. As a result, the passage cross-section for the coolant can optionally be changed automatically as a function of one or more operating variables of the reactor system.
