High temperatures require higher standards for the material of the rotor; as temperature rises, thermal stress increases, which can lead to an increase in the bending vibration levels of the shaft. Low temperatures may be caused by insufficient superheat of the steam, resulting in water presence in it, and in severe cases this can cause liquid slugging that damages the impeller. If the required level of superheat is not achieved, the turbine will not produce sufficient power, failing to reach the desired output and thus leading to accidents
