This project aims at developing a new Cr-coating technique on Zr alloy cladding. To protect the Zr alloy substrate and improve the oxidation resistance of cladding during severe accidents, it is desirable to apply Cr-coating to both of the outer and inner surface of Zr alloy cladding tube. In this project, study the characteristics of the different type of fuel assemblies adapted in APR-1400 design and 2D core to perform preliminary neutronics analyses by utilizing deterministic and Monte Carlo methods for reference cladding and coated cladding materials.
