Abstract

In order to provide a means to prevent migration of fission product lanthanides in metallic fuel at high burnup, adding an element to form stable compounds with lanthanides is proposed based on theoretical assessment. Alloys of U-10Zr and U-10Mo to simulate high burnup fuels with candidate addtives were made and characterized by opical metallography and scanning electron micrography to find the best candidate before in-pile tests. Prelimiary alloy characterization analysis shows that indium addition is effective to form compounds with Ce which is a necessary step to be effective to immobilize the LA.
