Hydrogen absorbed into zirconium alloy nuclear fuel cladding as a result of the waterside
corrosion reaction can affect the properties of nuclear fuel, principally through the …

Nucleation and formation of hydride precipitates in zirconium alloys have been an important
factor in limiting the lifetime of nuclear fuel cladding for over 50 years. This review provides a …

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 …

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 …

Titanium (Ti) and its alloys are attractive for a wide variety of structural and functional
applications owing to excellent specific strength, toughness and stiffness, and corrosion …

The ingress of hydrogen during corrosion in service can degrade the mechanical properties
of zirconium alloy nuclear fuel cladding because of the formation of brittle hydrides. The …

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 …

This paper presents observations of in situ heating and cooling cycles using synchrotron X-
ray diffraction carried out on Zircaloy-4 plates charged to different levels of hydrogen …

Grain boundary characteristics play a crucial role in the formation of intergranular hydrides,
which may cause brittle fracture in zirconium alloys. However, the impact of grain boundary …

We report a phase-field model for simulating metal hydride formation involving large volume
expansion in single-and polycrystals. As an example, we consider δ-hydride formation in α …
