PPL Corp. shut down the 1,149 MW Unit 1 reactor at the two-unit PPL Susquehanna nuclear power plant to inspect turbine blades as a precautionary move.
Workers at the plant found defective turbine blades in early May at the 1,140 MW Unit 2 at the plant during a scheduled maintenance and refueling outage when the blades showed signs of cracking and metal fatigue. Workers shut down Unit 1 May 17 to inspect for similar damage.
Unit 1 entered service in 1982 and Unit 2 entered service in 1984. Both are GE Type 4 boiling water reactors.
Officials with PPL said no shortage of electricity was anticipated and that other power plants in the PJM Interconnection are supplying electricity.
