Defects created by radiation damage in power reactor materials give rise to an evolving microstructure and result in changes in material properties. The effects involved occur over wide scales of length and time and are not generally open to direct experimental study. They need to be modelled and understood to underpin engineering codes for material performance. The proposed research will develop and apply multiscale computer simulation techniques to study the defects and processes that affect changes in mechanical properties. Most of the defects in question are created in displacement cascades and recent work has shown that most are formed in small glissile and sessile clusters. During evolution, some migrate towards dislocations, where they may for atmospheres, some interact with each other and form rafts, and some remain isolated in the microstructure. The interaction of these features and irradiation-induced precipitates with moving dislocations has a strong influence on the mechanical properties. Modelling to understand and predict the processes involved requires simulation at the atomic and continuum levels, and both will be carried out in an integrated approach, building on the experience for which we have demonstrated international standing. Collaboration to co-ordinate the modelling with experimental programmes of several groups will occur.
