The rotor material of investigated turbine is 30Cr1Mo1V, which is a pattern of N600-24.2/566/566 unit.
In regard to Westinghouse model, variable physical properties of rotor material must be taken into account.
Referring to WH model expression, it can be explained as that the material properties of the rotor are taken into account in this method, but ignored the influence of steam parameters, rotor speed and unit load.
