The embrittlement of the vessel is one of the lifetime limitation of current operating reactors. It is partly linked to the formation of solute clusters . A lot of work was done in recent decades to understand their formation mechanism . However, most of the studies were done on materials irradiated at fluxes up to seven order of magnitude higher than operating reactors and may lead to problems of transferability. In austenitic steels, the flux effect can be partly taken into account by a simple temperature shift (ΔT) .
In this study, we have investigated by Cluster Dynamics modelling the ΔT validity in a ferritic alloy. The experimental validation of the modelling has been performed on an ion irradiated Fe3%Ni alloy at two fluxes and 2 temperatures.
