The zirconium alloys used in nuclear industry include mainly Zr–Sn and Zr–Nb alloys of
different chemical composition, microstructure and susceptibility to both hydrogen …

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 …

Zirconium alloys are widely used for fuel cladding and in pressure tubes, fuel channels
(boxes), and fuel spacer grids in almost all water-cooled reactors: light water reactors such …

Faceted features are frequently observed on the fracture surfaces of titanium alloys that have
failed by static loading, continuous cycling, dwell fatigue loading, and stress corrosion …

The orientation and distribution of hydrides formed in zirconium alloy nuclear fuel cladding
can strongly influence material behavior and in particular resistance to crack growth. The …

Prestorage drying operations of high-burnup fuel may make Zircaloy-4 (Zry-4) fuel cladding
more susceptible to failure, especially during fuel handling, transport, and post-storage …

The formation of radial hydrides in stress-relief annealed Zircaloy-4 cladding was studied.
Specimens were firstly hydrided to different target hydrogen levels from 100 to 600wtppm …

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 …

Hydride reorientation degrades the mechanical performance of Zr alloys. However, the
mechanism by which hydride reorientation affects fatigue behavior is unclear. In this study …

Abstract δ-hydride structures in Zr nuclear fuel-rod cladding significantly affect mechanical
properties. A micromechanical phase-field model is developed to investigate the effect of …
