RPV (reactor pressure vessel) is the only core equipment that cannot be replaced during the life of the reactor. Radiation embrittlement is its main performance issue, and the precipitation of Cu-rich clusters is one of the main reasons for the embrittlement of RPV steel. In this paper, the multi-scale model is established and its simulation software MISA is developed for simulating evolution from primary defect generation to long-term evolution of defects and macro embrittlement impact, which can provide effective reference for the research and development of reactor materials.
