Unit 1 at PPL Corporation’s Susquehanna nuclear power plant in Luzerne County, PA, resumed generating electricity Wednesday after completing a turbine blade inspection.

The inspection found signs of cracking on turbine blades, confirming data from diagnostic equipment installed in the spring of 2012. PPL ended up replacing those blades.

“The inspection was another step in what has been a very systematic approach to understand what’s causing the cracks,” said Timothy S. Rausch, PPL Susquehanna senior vice president and chief nuclear officer. “We now have a solid understanding of the cause and are finalizing short-term and long-term plans to resolve the issue.”

PPL Susquehanna will shut down Unit 2 for a similar inspection in the future based on information provided by the diagnostic equipment installed on that unit, and will replace any cracked blades found on the turbine.

The work done this fall will serve as a bridge until the power plant begins making long-term fixes starting in the spring of 2013.
