PPL Susquehanna will keep one of its two nuclear reactors shut down longer than anticipated after recent inspections revealed defective blades within a turbine, according to The Standard Speaker newspaper.
Unit 2, originally shut down April 4 for a planned refueling and maintenance outage, will be out of commission for an additional four to six weeks to replace turbine blades that show signs of cracking and metal fatigue, according to the article. Inspectors found the defective blades in a low-pressure turbine, part of a shaft that includes two other low-pressure turbines, a high-pressure turbine and a generator.
Replacing the blades could cost between $20 million and $30 million, the article said.
