Plutonium Futures - The Science 2024
Jean Aupiais is a professor of radiochemistry at the National Institute of Nuclear Science and Technology located at the CEA Saclay center. He defended his thesis in 1990 on the quantification of thorium and uranium isotopes in basaltic rocks in order to discriminate between natural and anthropogenic uranium. He obtained the Habilitation à Diriger des Recherches (Dr. Habil.) in 2001 for which he summarized his research activities on the measurement of alpha emitters by alpha liquid scintillation. He presently focuses his research on actinide speciation in environment by means of a hyphenated technique called CE-ICPMS (capillary electrophoresis coupled to an Inductively Coupled Plasma Mass Spectrometer); with particular emphasis on the solution thermodynamics of pentavalent plutonium.
