Operators at PPL Corporation’s Susquehanna nuclear power plant began shutting down Unit 2 early Saturday (9/14) to inspect its turbine blades. Data from the extensive vibration monitoring equipment installed on the turbine indicates that two turbine blades may have developed small cracks.
“After consultation with the equipment manufacturer, we have decided to take the most conservative action and shut down the unit to investigate,” said Timothy S. Rausch, senior vice president and Chief Nuclear Officer.
While the unit is shut down, workers will perform additional maintenance activities that can be done only when the unit is not operating.
The financial impact is not expected to be material. The company is maintaining the 2013 forecast of $2.25 to $2.40 per share in earnings from ongoing operations.
Rausch said that the Unit 1 turbine continues to be monitored for turbine vibration and to operate at full power.
The Susquehanna plant, located in Luzerne County about seven miles north of Berwick, is owned jointly by PPL Susquehanna LLC and Allegheny Electric Cooperative Inc. and is operated by PPL Susquehanna.
