Abstract Scope |
Advanced materials that withstand the harsh operational conditions expected in commercial fusion reactors represent a phenomenal technological challenge. Tungsten, a promising candidate for plasma-facing material, presents drawbacks, as its stubbornness to retain H and He, leading to the appearance of bubbles, cracks, and exfoliation. Nanostructured materials with a high grain boundary density seem to be more resistant to radiation damage, helping to contain unwanted wrongdoers.
As in real life marriage is plagued by daily routine and materialism, so do coexisting point defects interact when coupled together in a tungsten GB. This contribution summarizes the efforts undertaken by our team by means of modelling techniques trying to match up the results of evil experiments designed to harm, in a quest to optimize material performance avoiding catastrophic failures. Hopefully, a golden wedding lies ahead in which the power of fusion is harnessed for the benefit of humans and planet alike. |
