劣化メカニズムに基づく中性子束効果の検討
概要
"Flux effects” on irradiation embrittlement in reactor pressure vessel materials is discussed in detail considering the interaction between two cascade damage occurred nearby. When no nano-scale structure exists nearby the cascade damages, flux effect can be categorized into three physical phenomena related to different irradiation-induced defects interaction. Interaction between a cascade damage and nano-scale structures, such as solute atom clusters, is important to model the growth phase of these structures, and the importance of flux effect would be relatively lower than in their nucleation phase.
