Abstract

Formation of intermetallic compounds of lanthanide fission products within uranium-based metallic fuels with added dopant(s) has been proposed to arrest fission products within the metallic-matrix, before lanthanides chemically react with cladding materials, leading to degradation of the cladding. Unlike previous trial-and-error approach, here we present ab-initio based generic alloy-design principles to identify dopant(s) for a given lanthanide to form dopant-lanthanide intermetallic. Our method correctly identifies previously known dopant like Pd, as well as predict novel dopants (AsandSe) which can bind fission product Nd within U-matrix. Formation of our expected NdAs intermetallic within the U-matrix has been confirmed experimentally.

Interactions and immobilization of lanthanides with dopants in uranium-based metallic fuels

Journal Article Khanal, Rabi ; Jerred, Nathan ; Benson, Michael T. ; ... - Journal of Nuclear Materials

In uranium-based fuels, production and migration of lanthanide fission products and subsequent chemical interactions with cladding constituents lead to fuel–cladding chemical interaction (FCCI), limiting fuel performance. In general, dopant addition to the fuel matrix to arrest lanthanides within the fuel by forming intermetallics is found to be effective in mitigating FCCI. Recently, we proposed ab-initio based alloy-design principles, which can be useful in identifying dopant(s) that can bind a lanthanide (Nd) inside the fuel matrix. Here, we demonstrate the robustness of such principles by performing a systematic study to choose dopants to form compounds with a range of experimentally-observed lanthanidemore »« less

Role of zirconium in neodymium-dopants interactions within uranium-based metallic fuels

Journal Article Khanal, Rabi ; Ayers, Nicholas ; Jerred, Nathan ; ... - Nuclear Materials and Energy

Metallic fuels proposed for advanced nuclear reactors are found to be superior to other fuel types in terms of high thermal conductivity, proliferation resistance, excellent compatibility with the sodium coolant, and in some configurations inherent safety. One performance limitation of metallic fuel systems is the chemical interaction of fuel, and the surrounding cladding materials commonly, known as fuel-cladding-chemical interaction (FCCI). The use of dopants that form intermetallics with lanthanides within the fuel matrix was found to be effective in binding with FCCI–causing lanthanides and arresting them within the fuel matrix. While most computational studies till now have been focused onmore »« less

Evaluation of Tellurium as a Fuel Additive in Neodymium-Containing U-Zr Metallic Fuel

Journal Article Jerred, Nathan D. ; Khanal, Rabi ; Benson, Michael T. ; ... - Scientific Reports

Phase-stability in a U-Zr-Te-Nd multi-component metallic fuel for advanced nuclear reactors is systematically investigated by taking into account binary, ternary and quaternary interactions between elements involved. Historically, the onset of fuel-cladding chemical interactions (FCCI) greatly limits the burnup potential of U-Zr fuels primarily due to interactions between lanthanide fission products and cladding constituents. Tellurium (Te) is evaluated as a potential additive for U-Zr fuels to bind with lanthanide fission products, e.g. neodymium (Nd), negating or mitigating the FCCI effect. Potential fresh fuel alloy compositions with the Te additive, U-Zr-Te, are characterized. Te is found to completely bind with Zr withinmore »« less

Out-of-pile and postirradiated examination of lanthanide and lanthanide-palladium interactions for metallic fuel

Journal Article Benson, Michael T. ; Harp, Jason M. ; Xie, Yi ; ... - Journal of Nuclear Materials

Palladium is being investigated as a fuel additive to bind with and potentially immobilize lanthanide fission products. A primary cause of fuel-cladding chemical interaction (FCCI) is the lanthanide fission products migrating to the fuel periphery and interacting with the cladding. This interaction will lead to wastage of the cladding and eventually to a cladding breach. Palladium has previously been identified as a promising additive used to prevent or decrease FCCI by reacting with the lanthanide fission products. In the current study, an alloy cast from the four highest abundant lanthanides found in irradiated metallic fuel, Nd, Ce, Pr, and La,more »« less

Microstructural characterization of annealed U-20Pu-10Zr-3.86Pd and U-20Pu-10Zr-3.86Pd-4.3Ln

Journal Article Benson, Michael T. ; Xie, Yi ; He, Lingfeng ; ... - Journal of Nuclear Materials

Palladium is being investigated as a potential additive to metallic fuel to bind fission product lanthanides, with the goal of reducing or preventing fuel-cladding chemical interactions (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 is the microstructural characterization of annealed U-20Pu-10Zr-3.86Pd and U-20Pu-10Zr-3.86Pd-4.3Ln in wt. %, where Ln = 53Nd-25Ce-16Pr-6La, using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). In both alloys, the matrix ismore »« less
