Investigation of the orientation dependence of hydrogen diffusion in nuclear fuel cladding tubes made of zirconium alloys
The anisotropy of the hydrogen diffusion dynamics in hexagonal zirconium-based nuclear fuel cladding tube materials shall be investigated in-situ by means of neutron imaging. Due to their fabrication process they have a strong texture and thus the grain orientation in axial direction of the hexagonal lattice differs from the orientation in circumferential direction. As a consequence, the anisotropic hydrogen diffusion process differs between different cladding tube materials and between the direction of the uptake process. In order to model the hydrogen behaviour during long term dry storage of spent nuclear fuels, the anisotropy effect of the hydrogen diffusivity has to be determined precisely. Therefore, neutron imaging is the best and most precise measurement and visualisation method to record the process in-situ.
