Description

Automatic translation: Introduction: The pebble bed reactor consists of a cylindrical container that is filled with a graphite reflector is lined and spherical in bulk Contains fuel elements. The cooling is effected by helium, which flows through this ball bed. The fuel assemblies are under operation slowly peeled off at the bottom and replaced with fresh ones from above. At AVR and THTR, the discharged balls are reinserted several times, until they have reached a specified target burnup.

Abstract (German)

Einleitung: Der Kugelhaufenreaktor besteht aus einem zylindrischen Behälter, der mit einem Graphitreflektor ausgekleidet ist und in loser Schüttung kugelförmige Brennelemente enthält. Die Kühlung wird durch Helium bewirkt, welches diese Kugel schüttung durchströmt. Unter Betrieb werden die Brennelemente langsam unten abgezogen und von oben durch frische ersetzt. Bei AVR und THTR werden die entladenen Kugeln mehrfach wieder eingesetzt, bis sie einen vorgegebenen Zielabbrand erreicht haben.
