Preparation and characterisation of Pd nanoparticles doped UO2 samples

To assess the safety of the deep geological disposal that would store the spent nuclear fuel (SNF), studies are centred on the SNF behaviour under repository conditions. UO2, which is the most common compound of SNF matrix, is highly sensitive to the redox potential and it could be oxidised to more...
