Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Verwertung von Metallteilen, die durch Uran radioaktiv kontaminiert sind. Dabei werden die Metallteile aufgeschmolzen, so daß sich eine Schmelze und eine Schlacke bilden. Den Metallteilen, der Schmelze und/oder der Schlacke wird an U 235 verarmtes Uran beigemischt. Es ist vorgesehen, daß das an U 235 verarmte Uran in der Form von Uranglas beigemischt wird.
(EN)
The invention concerns a method of reprocessing metal parts contaminated with uranium. The metal parts are smelted to form a melt and slag and U235-depleted uranium is mixed with the metal parts, the melt and/or the slag. It is envisaged that the U235-depleted uranium should be added in the form of uranium glass.
(FR)
L'invention concerne un procédé de revalorisation de pièces métalliques contaminées par de l'uranium. Ce procédé consiste à faire fondre des pièces métalliques de façon à obtenir une matière fondue et des scories, puis à mélanger aux pièces métalliques, à la matière fondue et/ou aux scories, de l'uranium appauvri en uranium 235, sous forme de verre à l'urane.
