Thèmes de Recherche :
- Cristallochimie de systèmes polyanioniques incorporant des radionucléides tétravalents (Uranium, Thorium).
- Recherches en collaboration avec AREVA NC.
Recherche Actuelle :
Après utilisation, le combustible nucléaire usé génère une quantité importante de déchets dont certain, les produits de fission et les actinides mineurs, génèrent une radiotoxicité très importante. Il convient alors de chercher des moyens de pouvoir séparer et éventuellement récupérer les éléments valorisables du reste des déchets ultimes au sein de ce combustible. Le procédé PUREX (Plutonium and Uranium Refining by Extraction) est actuellement mis en œuvre et permet de récupérer l’uranium et le plutonium avec un très grand degré de pureté. D’autres procédés sont à l’étude concernant la séparation des autres éléments potentiellement valorisables.
Mes travaux de recherche sont actuellement centrés sur l’utilisation du polyoxométallate trivacant {SiW9O34} pour chélater des éléments tétravalents tels que le cérium(IV) (comme simulant d’actinides), le thorium(IV) et l’Uranium(IV). Cette association a conduit à l’obtention de composés de types sandwich {U4(m3-O)2(SiW9O34)2(CH3COO)2} et {Th3(m3-O)(m2-OH)3(SiW9O34)2} et ouvre une voie concernant l’utilisation de ces polyanions comme ligand pour la stabilisation et la séparation de cations tétravalents à partir du mélange de cations à divers degrés d’oxydation.
