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 …

Fuel performance codes are critical tools for the design, certification, and safety analysis of
nuclear reactors. However, their ability to predict fuel behavior under abnormal conditions is …

A method for rapidly predicting the formation and stability of undiscovered single phase high-
entropy alloys (SPHEAs) is provided. Our software implementation of the algorithm uses …

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 …

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

The crystal structure of the interfacial areas of a δ-FCC water-quenched nano-hydride was
characterized by electron energy-loss spectroscopy (EELS) and electron diffraction. EELS …

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 equiatomic TiZrNbHfTa high entropy alloy (HEA) and its hydrides (TiZrNbHfTaH 0.4-2.0)
have been modelled at the atomic scale and the phase transformations that occur during …

This report presents an accelerated kinetic Monte Carlo (KMC) method to compute the
diffusivity of hydrogen in hcp metals and alloys, considering both thermally activated …

One of the main degradation mechanisms of the zirconium alloys used in nuclear reactors is
hydrogen embrittlement and hydride formation. The formation of zirconium hydrides is …
