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 …

Zircaloy is extensively used as a nuclear fuel cladding tube material. The fuel cladding
encapsulates radioactive fuel pellet and it is resorted to an exceptionally harsh environment …

In the spent fuel storage phase, nuclear fuel cladding is subjected to increased
embrittlement owing to a large amount of hydride precipitation. This study compares the …

Hydrides are at the center source of mechanical degradation affecting Zr-based nuclear fuel
cladding integrity during in-reactor service and even spent fuel storage. This study presents …

Hydrogen pick-up and hydride precipitation can lead to embrittlement and fracture strength
reduction of nuclear fuel cladding tubes made of Zircaloy. Plastic deformation of hydride …

Based on density functional theory calculations, the elastic mechanical properties and
kinetic diffusion behaviors of hydrogen in cubic and tetragonal metal hydrides MH 2 (M= Y …

Nano-beam electron diffraction has been used to quantify the elastic strain field associated
with δ-hydride needles embedded in an α-Zr matrix. It has been found that the volume misfit …

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

We present a detailed study on the electronic structure, mechanical properties, phase
stability, and thermodynamic properties of four polymorphs of crystalline zirconium hydride …

The diffusion of hydrogen in Zircalloy fuel cladding components and its associated delayed
hydride cracking (DHC) mechanism remain a bottleneck in nuclear fission. Through Crystal …
