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 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 …

Abstract Indian Pressurized Heavy Water Reactors (IPHWRs) uses Zr-2.5 Nb alloy pressure
tube (PT) in cold work and stress relieved condition. These PTs are subjected to extreme …

In a reactivity-initiated accident, cladding failure may occur by crack initiation within a defect
such as a hydride rim or blister and subsequent crack propagation through the thickness of …

The effect of hydrogen on the fracture behaviour of a Zircaloy-4 alloy was analysed
performing simultaneous fracture mechanics tests of small SE (B) specimens and in situ …

Normalization method is more convenient than unloading compliance method in
determining J-resistance (JR) curve and fracture toughness of steel. However its …

Unloading compliance method (UC) and normalization method (NM) are two of the most
commonly used methods for determining the fracture toughness of steels. Since the NM has …

Normalization method (NM) is a practical method for determining the J–R curves and
fracture toughness of steels. There is some concern, however, about the performance of this …

This study successfully deals with the inhomogeneous dimension problem of load
separation assumption, which is the theoretical basis of the normalization method …

Axial fracture toughness of cold worked and stress relieved Zr-2.5 Nb pressure tube material
containing deuterium between 5 and 200wppm was determined as per ASTM E− 1820-15 …
