Tritium retention in W plasma-facing materials: Impact of the material structure and helium irradiation

Publikováno v: Nuclear Materials and Energy, Vol 19, Iss , Pp 403-410 (2019)

Plasma-facing materials for next generation fusion devices, like ITER and DEMO, will be submitted to intense fluxes of light elements, notably He and H isotopes (HI). Our study focuses on tritium (T) retention on a wide range of W samples: first, dif
