NSUF 22-4493: Mechanical response and chemical effects at the fuel-cladding interface of HT-9 and metallic fuel

The proposed research will perform advanced post-irradiation examination, including microstructural, thermal, and mechanical characterization, on an accelerated in-pile experiment (FAST - Fission Accelerated Steady-state Test) irradiated U-10Zr fuel rodlets clad in HT-9 with and without Zr liners. Experiments will be complemented with lanthanide diffusion modeling. Results from the experiments and computational studies will be integrated into MARMOT/BISON.
