This standard specifies the inspection methods, evaluation standards and technical requirements for inspection equipment for the center hole of the uranium rotor of steam turbine generator units in thermal power plants. This standard is applicable to the inspection of integrally forged rotors with center holes of steam turbine generator sets in service in thermal power plants. It is also applicable to the inspection of rotors with center holes of steam turbine generator sets in the manufacturing stage. The inspection of rotors with center holes of nuclear power generating units can be implemented as a reference.
