Short summary
Since the requirement of the proof of safety to up to 100 years arises, integrity of the spent fuel elements in prolonged interim storage and long-term repository is getting more critical issue. In response to this safety matter, we developed and applied a multiscale simulation methodology to assess the impact of the radiation induced microstructures on mechanical properties of the spent fuel elements to provide reliable structural performance limits and safety margin respectively.
