“…More specifically, increased Fe levels in α-Zr solid solution change the self-diffusion coefficient of Zr, accelerating irradiation growth [4]. The size, area fraction and composition of SPPs were found to be important for the H uptake in Zr-alloys [6]. The localisation of H leads to the precipitation of hydrides and to the detrimental embrittlement of the material by hydrides, or to the failure mechanism of delayed hydride cracking [7].…”
