PhD Thesis

  - PhD Student at IMPMC since 2013 (work funded by AREVA NC)

  - Project: Weathering impact of granitic waste rock piles at former uranium mines (Limousin, France)

  - Advisor: M. GERARD, L. GALOISY (PALM, IMPMC)

 

Granitic waste rock is the world’s 2nd most important waste material produced by uranium mining. Despite their low U-content, the stability of large volumes of granitic waste rocks piled in the landscape might become questionable during long term weathering. Compared to massive granite, these rocks have a higher specific surface and are more reactive to chemical and mechanical alteration. Our study focuses on waste rock piles exposed during 50 years of weathering in Central France. We use a multi-scale approach, associating field observations (soil alteration profiles) with mineralogical and geochemical investigations (DRX, ICP-MS, microscopy, microprobes: EDS / WDS, SEM and XAS), to assess the impact of incipient weathering on U-migration in the waste rock piles and the surrounding environment.

Mucoviscidose : simuler pour mieux soigner

La mucoviscidose est la plus fréquente des maladies rares, touchant principalement les fonctions respiratoires et digestives et affectant en moyenne 1 nouveau né sur 4 500 en France. Cette maladie génétique potentiellement grave est le résultat de mutations affectant la protéine CFTR (Cystic Fibrosis...
