摘要

All six units at the 180-MW Jenpeg Generating Station in Manitoba, Canada, experienced corrosion fatigue cracking of the turbine shaft at the fillet between the shaft body and runner coupling flange. The shafts were analyzed to determine the failure mechanism, then machined in-situ using a specialized machine to remove the cracks and improve the shaft geometry. Finally, the turbine shaft seal was redesigned to prevent shaft corrosion and facilitate future inspections of this critical area.
