Title: Investigation of tin as a fuel additive to control FCCI

Abstract

Tin is being investigated as a potential additive to metallic fuel to control fuel-cladding chemical interaction (FCCI). A primary cause of FCCI is the lanthanide fission products moving to the fuel periphery and interacting with the cladding. This interaction will lead to wastage of the cladding and eventually to a cladding breach. The current study investigates the microstructure of as-cast and annealed U-10Zr-4.3Sn and U-10Zr-4.3Sn-4.7Ln (where Ln=53Nd-25Ce-16Pr-6La) using SEM, TEM, and XRD. Diffusion couple results, between U-10Zr-4.3Sn and lanthanides, and between U-10Zr-4.3Sn-4.7Ln and Fe, will also be presented. This investigation shows that tin preferentially binds the lanthanides, which will prevent lanthanide migration and interaction with the cladding.
