Zirconium-base alloy used for light-water reactor

Zirconium-base alloy used for light-water reactor

The invention relates to a zirconium alloy material, particularly to a zirconium-base alloy used for a light water reactor. The zirconium-base alloy is composed of (wt %) Sn 0.80-1.20, Nb 0.90-1.25, Fe 0.12-0.45, O 0.06-0.15, C less than 0.15, N less than 0.008, and zirconium and impurities in balan...

Zusammenfassung:The invention relates to a zirconium alloy material, particularly to a zirconium-base alloy used for a light water reactor. The zirconium-base alloy is composed of (wt %) Sn 0.80-1.20, Nb 0.90-1.25, Fe 0.12-0.45, O 0.06-0.15, C less than 0.15, N less than 0.008, and zirconium and impurities in balance. By adding Fe and O two elements based on the current Zr-Sn-Nb alloy, the zirconium-base alloy with good corrosion-resisting property in all corrosion tests using 360 DEG C deionized water, 360 DEG C lithium-containing water solution, 400 DEG C steam and 500 DEG C can be prepared. The inventive zirconium-base alloy can be used as structural material of a nuclear reactor core.
