AcE

The AcE project aims to understand the incorporation and immobilization of actinides (An) in crystalline solid phases relevant to final disposal at the atomic level. The main objectives of the AcE project are (i) the development of synthesis strategies for An(IV)-doped solid phases, (ii) the characterization of the structural and physical properties of An-doped materials using combined atomistic and experimental approaches, and (iii) to characterize the behavior of An-doped solid phases after irradiation, e.g., long-term durability, dissolution behavior, mechanical stability, and the overall potential for An uptake in the matrix. These objectives are intended to contribute to the evaluation of innovative disposal strategies and to expand knowledge of the long-term behavior of An during disposal in deep geological repositories.
