Corrosion of Zirconium Alloys Used for Nuclear Fuel Cladding
TL;DR: In this article, the mechanisms of corrosion and hydrogen pickup and the role of alloy selection in minimizing both phenomena are considered on the basis of two principal characteristics: the pretransition kinetics and the loss of oxide protectiveness at transition.

Structure of zirconium alloy oxides formed in pure water studied with synchrotron radiation and optical microscopy: relation to corrosion rate
TL;DR: In this article, a detailed study of oxides formed in 360 °C water on four Zr-based alloys (Zircaloy-4, ZIRLO™,1 Zr−2.5%Nb and Zr•2.9%Cu) was undertaken to relate oxide structure to corrosion performance.
Book ChapterDOI
Corrosion of Zirconium Alloys
TL;DR: In this article, the twin processes of uniform oxidation and hydrogen embrittlement are described comprehensively in terms of their underlying mechanisms, and the emphasis of this chapter is on uniform oxidisation.

Water radiolysis and its effect upon in-reactor zircaloy corrosion
W. G. Burns,P. B. Moore +1 more
TL;DR: In this paper, computer simulation of the growth and decay of radioly tic species produced by β, γ and neutron irradiation of water at 25°C and 305°C has been performed.

Diffusion of oxygen in growing zirconia films
B. Cox,J.P. Pemsler +1 more
TL;DR: In this article, the authors used an ion microprobe mass spectrometer to measure oxidised zirconium and showed the presence of a thin diffusion zone near the surface in addition to the deeper diffusion profile identified by the previous technique using the 17 O (3 He,α) 16 O reaction.

Cationic Self‐Diffusion in Calcia‐Stabilized Zirconia
W. H. Rhodes,R. E. Carter +1 more
TL;DR: In this paper, self-diffusion of Zr in 12 and 16 mol.% CaO and of Ca in 16 ml.% CAO cubic zirconia was measured by the sectioning technique from 1700° to 2150°C.
Journal ArticleDOI
The kinetics and mechanism of the oxidation of zircaloy-2 at 350–500 °C
TL;DR: In this article, an analysis of the kinetics of reaction of Zircaloy-2 with oxygen and water vapour in the ranges 20 to 200 Torr and 350 to 500 °C is reported, based upon continuous measurements of the progress of oxidation by both gravimetric and manometric techniques.
Journal ArticleDOI
Multiple Rate Transitions in the Aqueous Corrosion of Zircaloy
TL;DR: In this paper, the authors considered several corrosion mechanisms in the light of the kinetics of Zircaloy-2, -3, and low nickel Zirca-2.
Journal ArticleDOI
A porosimeter for determining the sizes of flaws in zirconia or other insulating films “In Situ”
TL;DR: In this article, the resistive component of the impedance of the oxide film as a function of pressure (up to 105 psi) for a specimen immersed in mercury was used to determine the size distribution of flaws in the oxide.
