| Outline of Final Research Achievements |
Evolution of irradiation defects is sensitive to the difference of materials and environment, so that it has been required to perform a large number of irradiation tests to evaluate structural integrity of nuclear materials. The objective of this study was to design efficient irradiation experiences by the combination of different type of irradiation experiences. The followings were our major goals, which were successfully achieved in gold, stainless steels, and iron-based alloys; 1) Controlling the structure of irradiation defects; 2) Visualization of invisible defects and short-lifetime defects; 3) Continuous observation of a irradiation defect in same field-of-view.
This study contributed to resume the utilization of the High Fluence Irradiation Facility of the University of Tokyo severely suffered by the earthquake in 2011.
