Characterizations of high activity solid deposit samples from fission product tanks

Abstract : For the dismantling of reprocessing facilities in Marcoule, deposit solid samples coming from fission products tanks have been characterized in the laboratories and hot cells of the ATALANTE facility.This work required RandD developments in both the chemical and analytical fields. Some of the very specific analytical developments performed for these characterizations in hot cells, such as selective Cs decontamination by extraction chromatography and direct analysis of solid residues by L-line X-ray fluorescence dedicated to actinide analysis are presented.
