Abstract

Radioaktive Verdampferlaugen aus kerntechnischen Anlagen werden zur Endlagerung in beheizbaren Endlagerbehältern konditioniert. Dazu wird zuerst in einem Verdampfer auf 60 bis 85 Gew. % Trockensubstanzgehalt aufkonzentriert und dann im Endlagergefäß bei einer Temperatur, die mindestens der maximal im Endlager auftretenden Temperatur entspricht, solange Wasserdampf abgesaugt, bis ein fester Bodenkörper mit glatter Oberfläche entsteht. Radioactive evaporator liquors from nuclear technology Plants are used for final storage in heatable Conditioned repository containers. This is first done in an evaporator to 60 to 85% by weight Concentrated dry matter content and then in Repository vessel at a temperature that is at least the maximum temperature occurring in the repository corresponds as long as water vapor is sucked off until a solid floor with smooth surface is created.
