Description

Verfahren zum Beseitigen von radioaktiven Verunreinigungen aus Flüssigkeiten Die Erfindung betrifft ein Verfahren zum Beseitigen von radioaktiven Verunreinigungen aus Flüssigkeiten, insbesondere aus Wasser.Process for removing radioactive contaminants from liquids The invention relates to a method for removing radioactive contaminants from liquids, in particular from water.

Es sind bereits Verfahren zum Beseitigen von radioaktiven Verunreinigungen aus Flüssigkeiten, insbesondere auch aus Wasser, bekanntgeworden, bei denen die Flüssigkeit unter Anwendung von Unterdruck verdampft wird.There are already methods of removing radioactive contaminants from liquids, in particular from water, became known in which the Liquid is evaporated using negative pressure.

Den bekannten Verfahren haftet der Mangel an, daß der Verdampfungsprozeß eines großen Aufwandes an Apparaturen und Material bedarf. Dieser Aufwand ist so erheblich, daß man mitunter auf das Verdampfen verzichtet und verseuchte Flüssigkeiten in platzraubenden Gefäßen über große Zeiträume hinweg abklingen läßt.The known processes have the defect that the evaporation process requires a great deal of equipment and material. This effort is like that significant that one sometimes dispenses with the evaporation and contaminated liquids can fade away over long periods of time in bulky vessels.

Gemäß der Erfindung werden diese Mängel beseitigt, wenn man so verfährt, daß das Verdampfen ausschließlich unter Anwendung von Unterdruck erfolgt und daß dabei die Höhe des Unterdruckes mehrfach geändert wird. Dadurch wird der Verdampfungseffekt erheblich gesteigert.According to the invention, these deficiencies are eliminated if one proceeds in this way, that the evaporation takes place exclusively using negative pressure and that the level of the negative pressure is changed several times. This will make the evaporation effect significantly increased.

Das neue Verfahren bietet die Möglichkeit, die Verdampfung unmittelbar in den Abklingbehältern vorzunehmen. Die Abklingbehälter erhalten bei Anwendung des neuen Verfahrens wesentlich geringere Ausmaße als bisher.The new process offers the possibility of evaporation immediately to be carried out in the decay containers. The decay containers are preserved when used of the new process is much smaller than before.
