Development and validation of hybrid K-edge/K-XRF densitometer for assay of nuclear fuel from reprocessing plants

Atomic spectrometry update: review of advances in the analysis of metals, chemicals and materials

“…These same advantages were highlighted by Bootharajan et al for the XRF characterisation of spent fuel in a high dose reprocessing facility for advanced fuels in lead cells. 188 A hybrid K-edge/KXRF densitometer was developed and commissioned for this study, with validation using a series of U solutions, followed by measurement of mixed Th/U/Pu solutions. A separate study by Quemet et al compared K-edge densitometry with isotope dilution TIMS for U determination in pellet samples.…”
