Instrument for Measurement of Pu Concentration and Isotopics of Product Solutions at Tokai-Mura

摘要

Rapid analysis of product solutions for plutonium concentrations and isotopic distributions is accomplished by a new instrument currently installed at the reprocessing plant in Tokai-mura, Japan. Better than half-percent measurements of the Pu concentration are obtained by K-edge densitometry for concentrations approx. 250 g Pu/l in short count times. Isotopic fractions are determined with an accuracy of one percent or better in an additional 30-minute passive count. (ERA citation 05:019172)
