PURPOSE:To obtain a Zr alloy causing no nodular corrosion and having satisfactory ductility by specifying the volume fraction of precipitates in a Zr alloy contg. specified percentages of Sn, Fe and Cr. CONSTITUTION:The volume fraction of precipitates in an alloy consisting of, by weight, 1.0-2.0% Sn, 0.07-0.24% Fe, 0.05-0.15% Cr and the balance essentially Zr is regulated to <=0.4X10<-3>. The resulting Zr alloy can be used to manufacture a fuel cladding pipe for a nuclear reactor, a nuclear fuel element contg. the cladding pipe, a spacer, a water rod, a channel box, a control rod guide pipe and a control rod for discharging water. |
