Method and device for the dry preparation of ceramic uranium dioxide nuclear fuel wastes
Description
Reprocessing of waste, resulting from the production of ceramic sintered bodies from uranium dioxide for use as nuclear fuel, in a dry process into very finely dispersed pure U3O8 powder may be improved by applying vibrating screening during oxidation. An appropriate device is described. (UWI)

Die Wiederaufarbeitung von Schrott, der bei der Herstellung von keramischen Sinterkoerpern aus Urandioxid fuer die Verwendung als Kernbrennstoff anfaellt, im trockenen Verfahren zu einem sehr feinteiligen, reinen U3O8-Pulver laesst sich dadurch verbessern, dass waehrend des Oxitationsvorganges eine vibrierende Siebung stattfindet. Eine geeignete Vorrichtung wird beschrieben. (UWI)Files
