Unit 1 at the 2,500 MW Susquehanna nuclear power plant in Luzerne County, Pa., resumed generating electricity for customers June 7 after a scheduled refueling and maintenance outage.
Plant operator PPL Susquehanna LLC also said that it found no turbine blade cracks on Unit 2, which was shut down May 30 for inspection based on the discovery of cracks on some Unit 1 turbine blades, which were replaced during the recent outage. Diagnostic equipment on the turbines of both units will be used to validate the suspected causes currently under engineering review.
During the Unit 1 scheduled outage, which began March 31, workers completed hundreds of maintenance tasks and upgrades, replaced about 40 percent of the uranium fuel, and replaced turbine blades where indications of cracks were found during an inspection.
PPL Corp. (NYSE: PPL) said the total impact of the turbine blade inspection and replacements for both units is not expected to be material.
The Susquehanna plant, located about seven miles north of Berwick, is owned jointly by PPL Susquehanna LLC and Allegheny Electric Co-op Inc. and is operated by PPL Susquehanna LLC.
