Transmission electron microscopy experiments coupled with 4 MeV Au and 390 keV Xe implantations were conducted on polycrystalline UO2 thin foils in order to study the void change with damage, temperature (ranging from −180 to 1100 °C) and exogenou

International audience; Predicting the nuclear fuel microstructure at each moment of its irradiation cycle (nominal, power transient, accidental conditions) is a significant nuclear safety issue. For that, it is necessary to understand the impact of

Molecular dynamics study of the bulk temperature effect on primary radiation damage in uranium dioxide

Autor: C. Sabathier, G. Martin, Julia Wiktor, S. Maillard

The effect of bulk temperature on the primary damage induced by a displacement cascade was investigated in uranium dioxide using classical molecular dynamics simulations. In this study, the Morelon potentials were used to model the middle-range inter
