ISO 13464:1998, Simultaneous determination of uranium and plutonium in dissolver solutions from reprocessing plants -- Combined method using K-absorption edge and X-ray fluorescence spectrometry

This International Standard specifies a nondestructive method for the simultaneous determination of volumetric uranium and plutonium concentrations in nitric acid feed solutions from reprocessing plants. The method is directly applicable, without interference, to the original feed solution, which typically contains about 150 g.l−1 to 300 g.l−1 uranium and 1 g.l−1 to 2,5 g.l−1 plutonium in the presence of fission products with a total β,γ-activity of up to 10 TBq.l−1.
