Effects of irradiation on the oxidation of zirconium alloys in high temperature aqueous environments. A review
TLDR
The experimental data on the effect of fission fragment, neutron and gamma irradiation on the oxidation of zirconium alloys have been reviewed in this article, where it is shown that both fast neutron irradiation and the presence of free oxygen or oxidising radiolytic species must be simultaneously present before any effect can be observed in high temperature water.About:

Materials Challenges in Nuclear Energy
Steven J. Zinkle,Gary S. Was +1 more
TL;DR: In this article, the three major materials challenges for the current and next generation of water-cooled fission reactors are centered on two structural materials aging degradation issues (corrosion and stress corrosion cracking of structural materials and neutron-induced embrittlement of reactor pressure vessels), along with improved fuel system reliability and accident tolerance issues.

Some thoughts on the mechanisms of in-reactor corrosion of zirconium alloys
TL;DR: In this paper, the authors focus on those studies that have resulted in changed views of the importance of various mechanisms of corrosion in water-cooled PWRs and present a review of these studies.
Journal ArticleDOI
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.

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.

Oxidation of metals by short circuit and lattice diffusion of oxygen
TL;DR: In this paper, an expression for the initial oxidation rates of metals based upon the model of inward movement of oxygen through the lattice and along low resistance paths within the superficial oxide film was derived.

Oxidation of Zirconium and Zirconium Alloys
TL;DR: In this paper, the reaction rate of massive (parallelepiped) samples was best expressed by the cubic rate law, and the activation energy was calculated to be 42.7 kcal per mole, and cubic rate constant in ( mu g per sq cm) per minute can be expressed as k = (5.94 x 10/sup 16/)e/sup -42//sup,70//sup 0// s/sup T/.

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.
