Diffusion Couple Investigations of Ce-Sb Compounds with Fe
Abstract
Fission product lanthanides can migrate to the fuel periphery and react with cladding, causing fuel-cladding chemical interaction (FCCI). Adding a fuel additive dopant, such as Sb, can bind lanthanides, such as Ce, into metallic compounds to prevent migration. The present study focuses on the thermodynamic stability of Ce-Sb compounds when in contact with the major cladding constituent Fe by conducting diffusion couple tests. Here, Ce-Sb compounds have shown high thermodynamic stability as they did not react with Fe; when Fe-Sb compounds contacted with Ce, Sb was separated out of the Fe-Sb compounds and formed the higher stability Ce-Sb compounds.
