Description

The stress corrosion cracking (SCC) of nuclear LP rotors is a worldwide problem since late 1960's, that has been considered as the major factor for maintaining the reliability of turbines for nuclear power plants. Since the problem is not exceptional to the local nuclear power plants, some efforts have been undertaken in order to mitigate or resolve the SCC problem. The main activities in this study were focused on the survey and determination of SCC growth rates, critical crack length calculation by finite element methods (FEM), and comparison of life assessment models. Examples of deterministic and probabilistic life assessment for a local steam rotor disc with SCC cracks are presented
