Zirconium (Zr) hydrides threaten the reliability of fuel assembly and have repeatedly induced
failures in cladding tubes and pressure vessels. Thus, they attract a broad range of research …

Hydrogen embrittlement of zirconium alloys is one of the main causes of the mechanical
degradation of the fuel cladding in light water reactors, and has therefore been extensively …

Hydride precipitates that develop in Zr after absorbing hydrogen can impart significant
material hardening and embrittlement. Here, we use electrolytic hydrogen charging to …

This study focuses on investigating the effects of the localized stresses that develop during
formation of zirconium hydrides on the redistribution of hydrogen atoms in the zirconium …

The formation of hydrides challenges the integrity of zirconium (Zr) fuel cladding in nuclear
reactors. The dynamics of hydride precipitation are complex. Especially, the formation of the …

In this study, the microstructural changes induced by doping of Nb in Zr were investigated by
the combined utilization of electron backscatter diffraction and electron transmission …

The long-term safety of water-based nuclear reactors relies in part on the reliability of
zirconium-based nuclear fuel cladding. Yet the progressive ingress of hydrogen during …

Understanding the hydride platelet reorientation in zirconium (Zr) alloy fuel claddings that
potentially occurs during the dry storage process of spent nuclear fuel is of great …

A path for homogeneous γ hydride formation in hcp α-Zr, from solid solution to the ζ and then
the γ hydride, was demonstrated using molecular static calculations and molecular dynamic …

The hydrogenation and dehydrogenation behaviors of a zirconium alloy were in-situ studied
by scanning electron microscopy and transmission electron microscopy. The zirconium alloy …
