The progress of SPP oxidation in zircaloy-4 and its relation to corrosion and hydrogen pickup

Abstract:

The evolution of Cr and Fe within the oxide formed on Zircaloy-4 in high-temperature pure water and a high-pH aqueous environment has been followed in detail by electron energy loss spectroscopy (EELS). The oxidation states of Cr, Fe and Zr have been determined as a function of exposure time and location in the oxide film. Much Cr and all the Fe diffuse out of the original Laves phase and precipitate within cracks or on the outer oxide surface. Cr oxidation is complete prior to transition; Fe...
