Introduction Zirconium alloys have been widely used for fuel cladding and other core components in a nuclear reactor and among them Zircaloy-4 has been widely used as a fuel cladding material for pressurized water reactors for a long time.
The recent trend towards extended burn-up and high pH operation of nuclear power plants has led to an increased demand for higher corrosion resistance of nuclear fuel cladding materials as well as improvement of its mechanical properties.
