The goal of this project is to identify minor alloying additions (dopants) for minimizing or eliminating the effect of fuel cladding chemical interactions (FCCI) in fast reactor metallic fuels. The proposed program combines the following research tasks: i) Selection of dopant elements based on using electronic structure calculated thermokinetic and bonding parameters of dopant-lanthanide, dopant-matrix and dopant-lanthanide-point defect systems; ii) fuel-dopant-lanthanide fabrication casting; iii) perform diffusion-couple experiments; iv) microstructure and compositional characterization of the annealed diffusion couple experiments; v) incorporation of computational code in results in NEAMS-based fuel performance code.
