“…Reduction of water at the oxide/electrolyte interface is assumed to consume electrons supplied by the oxidation of zirconium. It has been proposed that the electronic conduction through the oxide proceeds via easy paths associated with second phase particles embedded in the oxide matrix [1,3] or is due to the semiconductor properties of the formed oxide [5]. The extent of coupling between the electronic and ionic fluxes has remained largely unquantified.…”

“…Clearly, if electron transport controls the oxidation kinetics, the precipitates embedded into the growing oxide and the extrinsic compensating defects due to aliovalent cations in solid solution could have a significant effect on the corrosion kinetics by affecting the oxide electronic conductivity [35][36][37].…”

Although the optimization of zirconium-based alloys has led to significant improvements in hydrogen pickup and corrosion resistance, the mechanisms by which such alloy improvements occur are still not well understood. In an effort to understand such mechanisms, we conducted a systematic study of the alloy effect on hydrogen pickup, using advanced characterization techniques to rationalize precise measurements of hydrogen pickup. The hydrogen pickup fraction was accurately measured for a specially designed set of commercial and model alloys to investigate the effects of alloying elements, microstructure, and corrosion kinetics on hydrogen uptake. Two different techniques for measuring hydrogen concentrations were used: a destructive technique, vacuum hot extraction, and a non-destructive one, cold neutron prompt gamma activation analysis. The results indicate that hydrogen pickup varies not only from alloy to alloy, but also during the corrosion process for a given alloy. These variations result from the process of charge balance during the corrosion reaction, such that the pickup of hydrogen decreases when the rate of electron transport or Manuscript
