After studying the damage caused by the passage of heavy ions in minerals, in the context of thermochronology using traces of uranium fission, and then the storage of nuclear waste, my research focused on the storage of tritiated water in a zeolite matrix. The radiolysis generated by tritium beta particles leads to the formation of products that disappear synchronously in zeolite 4A by recombination. It is the primary mechanism of this recombination that needs to be clarified in order to optimise the phenomenon. (in collaboration with the CEA’s DAM, Valduc).
