| Abstract: | Stress Corrosion Cracking(SCC) is one of the ubiquitous problems in the low pressure components of the nuclear steam turbine working in moisture environment.A life assessment procedure using Python language on ABAQUS platform is developed to create a deterministic and probabilistic procedure based on Clark model.The major objective of the present study is to assess stress corrosion life of the low pressure components for the 1 000 MW nuclear steam turbine.The application can supply technical guarantees for key component-design of nuclear steam turbine. |
