HIGH MOLYBDENUM-CONTAINED ZIRCONIUM ALLOY COMPOSITION HAVING EXCELLENT CORROSION AND CREEP RESISTANCE, MANUFACTURING METHOD THEREOF AND USE THEREOF

摘要

PURPOSE: A high-concentration polybenum-contained zirconium alloy composition having excellent corrosion and creep resistance and a manufacturing method thereof are provided to be used in a nuclear fuel clothing pipe, a support lattice, and a core structure. CONSTITUTION: A high-concentration polybenum-contained zirconium alloy composition having excellent corrosion and creep resistance comprises 0.55-0.8 weight%, niobium of 0.2-0.4 weight%, tin of 0.2-0.4 weight%, one or more elements selected from a group consisting of iron, chrome and copper, and zirconium remnant. The total content of one or more elements is 0.1-1.0 weight%. The zirconium alloying composition comprises molybdenum 0.55-0.8 weight%, niobium 0.2-0.4 weight%, tin 0.2-0.4 weight%, iron 0.1-1.0 weight%, and zirconium remnant. The zirconium alloying composition comprises molybdenum 0.55-0.8 weight%, niobium 0.2-0.4 weight%, tin 0.2-0.4 weight%, chrome 0.1-1.0 weight%, and zirconium remnant.
