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.

Diffusion behavior of lanthanide-additive compounds (Ce₄Sb₃, Ce₂Sb, and CeTe) against HT9 and Fe

Journal Article Xie, Yi ; Zhang, Jinsuo ; Benson, Michael T. ; ... - Materials Characterization

Antimony and tellurium have been identified as promising additives in metallic fuel, which can immobilize free-lanthanide fission products into stable intermetallic compounds in order to mitigate the fuel-cladding chemical interaction. Ce₄Sb₃, Ce₂Sb, and CeTe are the primary compounds formed by Sb or Te with the lanthanide Ce present in the fuel. If these compounds are present at the outer periphery of the fuel, they will come in contact with and react with the cladding after the fuel swells. The present study investigates the reactivity of these compounds with two cladding materials, HT9 and Fe. The diffusion couple tests between thesemore »« less

Characterization of U-Zr fuel with alloying additive Sb for immobilizing fission product lanthanides

Journal Article Xie, Yi ; Benson, Michael T. ; King, James A. ; ... - Journal of Nuclear Materials

Fission product lanthanides can migrate to the fuel periphery and enhance fuel-cladding chemical interaction (FCCI). Adding Sb into the fuel alloy to bind lanthanides and thus to prevent lanthanides from migration has been proposed. The U-Zr fuel alloys were fabricated with compositions of U-10Zr-4.1Sb, U-10Zr-4.1Sb-4Ce, U-10Zr-2.07Sb, and U-10Zr-2.07Sb-2Ce wt.% by arc melting, and analyzed under scanning electron microscope (SEM) for the microstructure and elemental compositions. In the Ce-free alloy, Sb was found in Sb-Zr precipitates; while in the Ce-contained alloy, Sb was found in the form of intermetallic compounds Ce₄Sb₃ and Ce₂Sb without any Sb-Zr precipitates. In conclusion, antimony hasmore »« less

Lanthanide migration and immobilization in metallic fuels

Journal Article Xie, Yi ; Zhang, Jinsuo ; Li, Xiang ; ... - Progress in Nuclear Energy

It is recognized that the lanthanide fission products can enhance the fuel-cladding chemical interaction (FCCI), which is a key concern of using metallic fuels such as U-Zr in a sodium-cooled fast reactor. The present work conducts a critical review on the analysis of lanthanide functions in FCCIs. Available in-pile and out-of-pile data are first collected and analyzed, then the theories for lanthanide migration and redistribution in the fuel in operation are analyzed. For mitigating FCCIs, one of the effective method is applying fuel additives for immobilizing lanthanides. The review investigates four candidates of fuel additives (Pd, Sn, Sb and In),more »« less

Characterization of U-10Zr-2Sn-2Sb and U-10Zr-2Sn-2Sb-4Ln to assess Sn+Sb as a mixed additive system to bind lanthanides

Journal Article Benson, Michael T. ; Xie, Yi ; King, James A. ; ... - Journal of Nuclear Materials

In this paper, tin and antimony are being investigated as potential additives to metallic fuel to control fuel-cladding chemical interaction (FCCI). A primary cause of FCCI is lanthanide fission products moving to the fuel periphery and interacting with the cladding. This interaction can lead to wastage of the cladding and, given enough time or burn-up, eventually to a cladding breach. The current study involves a microstructural characterization of as-cast and annealed U-10Zr-2Sn-2Sb and U-10Zr-2Sn-2Sb-4Ln, where Ln = 53Nd-25Ce-16Pr-6La, all in wt %, as alloys which could prevent FCCI. Scanning electron microscopy (SEM) analysis and X-ray powder diffraction indicates the additive-Zrmore »« less

Experimental assessment of antimony (Sb) in pure uranium for immobilizing fission product lanthanides

Journal Article Zhuo, Weiqian ; Xie, Yi ; Benson, Michael T. ; ... - Journal of Nuclear Materials

The use of fuel additives is one of the concepts to mitigate fuel cladding chemical interaction (FCCI) for metallic fuel because fission product lanthanides are expected to be immobilized by the additive. Antimony (Sb) has been discovered to be a good candidate in UZr fuel. The present study focuses on its mechanism for immobilization in pure uranium, U–4Sb alloy was fabricated to understand the Sb behavior, while U–4Sb–4Ce was fabricated to simulate the case when lanthanides are generated. Both of the as-cast and annealed samples were characterized by scanning electron microscope (SEM) and energy dispersive spectrometer (EDS). U–Sb precipitates aremore »« less
