Life assessment methodology for turbogenerator rotors: Volume 3, SAFER (Stress and Fracture Evaluation of Rotors) code methodology tutorial for turbine rotor lifetime estimation
The Stress and Fracture Evaluation of Rotors (SAFER) computer code was developed by EPRI several year ago follwing the Gallatin rotor burst in 1974. SAFER combines the engineering disciplines of machine design, finite element stress analysis, heat transfer, non-destructive evaluation (NDE) techniques, mechanical metallurgy and fracture mechanics; this software tool provides the electric utility industry with a useful tool for an independent review and analysis of fully integral turbine-generator rotors with near bore flaws. The purpose of this SAER Tutorial is to provide the utility engineer with an overview and understanding other engineering disciplines used in the SAFER computer code and to provide several turbine-generator rotor example life assessment analyses with the appropriate input data to facilitate the technology transfer of the SAFER code to the electric utility industry. The intent of this Totorial is not to train utility engineers to become turbine-generator rotor designers, but rather to provide them with enough information to make independent analyses to check and unerstand the OEM's recommendations and to schedule maintenance and inspection outages. This SAFER Tutorial is composed of two volumes. This voluem describes the various data input and computer output in detail with the physcial meaning of the data, while the Appendices described each rotor life assessment with an explanation of the analysis recommendations. 53 figs., 40 tabs.
