The in-service hardening and increase of the Ductile Brittle Transition Temperature (DBTT) of Reactor Pressure Vessel (RPV) steels are controlled at the atomic scale by the clustering of point defects with co-segregation of alloying elements like Cu, Mn, Ni, Si and P. The effort and strategy within the European Project PERFECT for developing advanced multi-scale numerical tools to predict this microstructure and the induced hardening as well as their experimental validation at the relevant scale will be presented. The first results obtained since January 2004, starting date of PERFECT, will be discussed and perspectives given.

AbstractThe plutonium α decay leads to the formation of numerous point defects in the metal structure. The multi-scale modeling of self-irradiation effects in plutonium alloys needs a quantitative knowledge of defects population properties. In this work, we initiated a parametric study of molecular dynamics displacement cascade simulations to get properties of defects microstructure such as number of point defects, number and size of clusters, spatial repartition and spatial expansion of the cascade. These data constitute some of the input parameters for the mesoscopic scale simulations. First results obtained for two 2 keV energy cascades simulations are presented and discussed.
