How to simplify the analytics for input-output accountability measurements in a reprocessing plant
Description
An analytical approach to high-performance uranium and plutonium accountancy measurements in reprocessing input and output solutions is presented, which provides larger operational simplicity than the conventionally applied chemical methods. The proposed alternative is based on energy-dispersive absorption edge and fluorescence X-ray spectrometry, using the proven and reliable K-edge densitometry technique as reference method. Two X-ray densitometers developed for accurate and reliable uranium and plutonium analysis in both the feed and product solutions are described. Practical experiences and results from their performance evaluation on actual process solutions from a reprocessing plant are presented and discussed. (orig.)

Fuer die mit hoher Genauigkeit durchzufuehrenden Uran- und Plutoniumbilanzierungsmessungen am Eingang und Ausgang einer Wiederaufarbeitungsanlage wird ein alternatives Messverfahren vorgeschlagen, welches die Analytik gegenueber den traditionell verwendeten chemischen Analysenmethoden wesentlich vereinfacht. Das alternative Messschema beruht auf den physikalischen Methoden der Roentgenabsorptiometrie und Roentgenfluoreszenzanalyse, wobei die erprobte und genaue K-Kantenabsorptiometrie als Referenzmethode eingesetzt wird. Es werden zwei Roentgenabsoprtiometer beschrieben, die fuer genaue und zuverlaessige Uran- und Plutoniumanalysen in den Eingangs- und Produktloesungen entwickelt wurden. Praktische Erfahrungen und Ergebnisse von deren Einsatz bei der Messung realer Prozessloesungen aus einer Wiederaufarbeitungsanlage werden dargestellt und diskutiert. (orig.)
