Capturing irradiation-enhanced corrosion of zircaloy-4 with a charge-based diffusion/drift phase field model
Zircaloy-4 has been used in pressurized water reactors (PWRs) for decades, and enhanced corrosion rates in reactors compared to out-of-pile have long been observed. However, the exact mechanism explaining the early departure from autoclave kinetics after 3-5 microns of oxide have formed has proved …
