| Abstract Scope |
Plasma-facing materials are submitted to intense fluxes of He and H isotopes (H, D and radioactive T transmutating as He), which can jeopardize preservation of their key properties throughout operation. He impact on the material microstructure will be presented, with experimental data from fusion devices to nanosciences studies to characterize He bubble formation, characteristics and evolution. Then, we will address consequences for T inventory through T2 gas-loading experiments, a high sensitivity technique free from any additional defect creation in the material. |
