| Abstract Scope |
Advanced cladding is critical for the development of advanced nuclear reactors with enhanced performance in heat transfer, radiation tolerance and neutron transparency. It will ensure adequate thermal conductivity and mechanical-dimensional stability of cladding base material, corrosion resistance and high temperature coolant compatibility of cladding surface, and chemical stability in the cladding inner-wall against fuel cladding chemical interaction (FCCI). This presentation summarizes the recent progress of ceramic coatings development for FCCI mitigation through both experimental investigation and model simulation. Scratch tests before and after thermal cycling are used for bond strength evaluation. Transmission electron microscopy (TEM) and atom probe tomography (APT) characterizations are used for interface microstructure. Density function theory (DFT) calculation is performed to evaluate the ceramic coating stoichiometry on the diffusion barrier strength to suppress FCCI. The results of interface microstructural and microchemistry on ceramic coating performance on bond strength, thermal and radiation stability will be discussed. |
