Paper Abstract

The aging hollow forged steel rotors of steam turbine and generator units typical to utility power plants are a major area of concern for the future safety and integrity of the overall power plant. These components are also critical in determining future inspection intervals for the turbine unit and its remaining life. Over the past five years a number of lifetime extension projects have been conducted using an integrated nondestructive evaluation (NDE), materials and fracture mechanics approach to determining inspection intervals and remaining life. These projects have resulted in extending inspection intervals, predicting remaining life, and restoring original equipment manufacturer (OEM) retired rotors to operation. Key aspects of the integrated program will be covered using the results of a recently completed project.
