PURPOSE: To provide a clad fuel tube superior in corrosion resistance and resultingly having a long life and its proper production method.
CONSTITUTION: On the outer surface of inner layer of a reactor clad fuel tube formed out of a zirconium-based alloy, the outer layer is coated by forming an anti-corrosion metal superior in corrosion resistivity to the zirconium-based alloy. For the anti-corrosion metal, Ti or titanium-based allopy is preferable. The production method for the cladding is as follows; on an inner layer materal formed with a zirconium base alloy, a composit material coated with an outer layer material formed with Ti or a titanium-based alloy superior in corrosion resistance to the zirconium-based alloy is hot-worked with a reduction ration of 5% or more within a temperature range of 500 to 850°C.
