    CORROSION RESISTANCE AND HIGH-TEMPERATURE BEHAVIOUR OF ZR-BASED CLADDING MATERIALS WITH CHROMIUM-BASED PVD COATINGS

  • Original language description

    "Following the Fukushima Daiichi accident, new nuclear fuel cladding designs improving the performance and enhancing nuclear power plants' safety have been extensively investigated. The chromium-based accident tolerant fuel cladding coating designs were developed by ALVEL in the frame of the project sponsored by the Ministry of Industry and Trade and UJP PRAHA in collaboration with CTU in Prague. This study introduces a set of experiments determining a wide range of coated cladding material properties. Metallic Cr, CrAl and multicomponent CrN + Cr were tested, focusing on long-term corrosion resistance during normal operating conditions, high-temperature oxidation in the steam environment and mechanical properties during an accidental transient. All coatings revealed enhancement in corrosion resistance when compared to Zr alloy. However, diffusion of chromium into the zirconium substrate was observed for the metallic chromium coatings at temperatures above Cr-Zr eutectic. Coating deposition is further beneficial for claddings' mechanical properties. Overall, all tested coatings may be attractive candidates as possible ATF claddings."
