Iron Corrosion-Resistance in Lead-Bismuth Eutectic Coolant by Molecular Dynamics Method

Abstract

In this present work, we report numerical study of iron corrosion in interaction with lead-bismuth eutectic. The goal of this work is to study how the oxygen can be used to reduce the corrosion rate of iron in lead-bismuth eutectic. The molecular dynamics method was applied to simulate corrosion process. By evaluating the diffusion coefficients, RDF functions, MSD curves of iron and also observed the crystal structure of iron before and after oxygen injection we concluded that a significant and efficient reduction can be achieved by injecting about 2% of oxygen into lead-bismuth eutectic.
