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 …

Because hydride microstructure can significantly influence Zr alloy nuclear fuel cladding's
ductility, a new metric has been developed to quantify hydride microstructure in 2D …

The primary objective of this article is to gather comprehensive experimental and theoretical
data on the fracture process of hydrogenated zirconium alloys at micro-and nano-levels and …

The fracture behavior of Zr-2.5 Nb pressure tube (PT) material containing radial hydrides
with hydrogen concentrations between 30 and 300wppm was evaluated between 25 and …

We propose an atomistically informed Eshelby's inclusion analysis to investigate the
morphology of secondary phases, which elastically interacted with each other through their …

Hydride reorientation experiments for unirradiated Zr-Nb alloy cladding tubes under multi-
axial stress states induced by internal pressurization were performed with peak cladding …

It is widely accepted that the characteristics of hydrides in the Zr-based nuclear fuel cladding
are critical factors determining the integrity of the spent fuel. Therefore, to mitigate any harm …

We energetically predicted the morphology of Zr hydride precipitates in a hexagonal close-
packed (HCP) Zr matrix. Considering Zr hydride precipitates as ellipsoids, we used …

PROPHET, a software that conducts an image analysis of hydrided Zircaloy for Radial
Hydride Fraction (RHF) and Radial Hydride Continuous Path (RHCP) evaluation using …

The effect of radial hydride on the room temperature fracture toughness of the Zr-2.5 Nb
pressure tube material with 100% radial hydrides and hydrogen content up to 320wppm was …
