Life assessment methodology for turbogenerator rotors: Volume 2, SAFER (Stress and Fracture Evaluation of Rotors) Code Engineering Tutorial: Final report
The Stress and Fracture Evaluation of Rotors (SAFER) computer code was developed by EPRI several years ago following 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 SAFER Tutorial is to provide the utility engineer with an overview and understanding of the engineering disciplines used in the SAFER computer code and to provide several turbine-generator rotor example life assesment analyses with the appropriate input data to facilitate the technology transfer of the SAFER code to the electric utility industry. The intent of this Tutorial 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 understand the OEM's recommendations and to schedule maintenance and inspection outages. This SAFER Tutorial is composed of two volumes. This report, Volume II, provides a brief description of the several engineering principels used in the SAFER Code. This Tutorial used in conjunction with the SAFER Computer Code User's Guide provides the necessary knowledge and methodology to conduct a turbine-generator rotor remaining life assessment. 85 refs., 33 figs., 1 tab.
