NSUF 24-5146: Irradiation effects on thermal conductivity and phase evolution in low burnup U-10Pu-10Zr
The objective of this experiment is to characterize the microstructure and measure the local thermal conductivity of low-burnup U-20Pu-10Zr within each region of fuel constituent redistribution. Microstructural features and elemental analysis will be examined using combined SEM/EDS approach. Additionally, TEM-based examinations will provide information on the phase transformations and grain evolution in each region of fuel element migration. The present phases identified will be correlated with local thermal conductivity measurements obtained using thermo-reflectance methods in the Thermal Conductivity Microscope (TCM). Ultimately, the work will be compared to results from complementary studies measuring local conductivity for ultra-low burnup and high-burnup U-20Pu-10Zr fuel samples, providing key information on interdependent evolution of fuel microstructure and local thermal properties and informing future metallic fuel model development.
