CORROSION RESISTANCE AND HIGH-TEMPERATURE BEHAVIOR OF CHROME-NICKEL ALLOY CLADDING MATERIAL
Original language description
Cr-Ni alloys has been recently proposed as a potential ATF concept, primarily due to its high corrosion resistance under normal operation conditions and high-temperature oxidation. It is tested by UJP PRAHA in collaboration with CTU in Prague in the frame of the project sponsored by the Technology Agency of the Czech Republic. A set of experiments determining a wide range of material properties were performed. The investigations in this contribution followed previous work. Material in as-received state was evaluated using TEM, SEM-EBSD, DSC, and XRD methods. The ongoing long-term autoclave tests revealed superb corrosion resistance compared to reference Zr-cladding material under simulated WWER normal operating conditions (at 360 °C), in steam at 400 °C, in steam at 500 °C, and water containing 70 ppm of Li (at 360 °C). A set of high-temperature steam oxidation experiments were performed to determine behavior at LOCA and DEC conditions. Weight gain, hydrogen content were measured. Microstructure analysis (LOM, EDS) and mechanical properties (offset-strain) were evaluated. Thermomechanical tests were performed to understand the cladding deformation and the burst conditions during high-temperature transients. The ballooning size, prolongation of time to burst, burst opening dimensions.
