BERWICK, Pa. -

Operators at PPL's Susquehanna nuclear power plant safely shut down the Unit 2 reactor Friday because a computer system that controls the reactor's water level was not functioning properly.

Operators manually shut down the reactor when they identified the malfunction and plant systems responded as designed., company officials said.

Susquehanna employees are investigating the reason for the loss of the computer system.

"Our operators are well-trained to manage situations like this," said Timothy S. Rausch, PPL Susquehanna senior vice president and chief nuclear officer. "All systems are functioning as expected to keep the unit in a safe condition."

While the unit is shut down, employees will address the control system malfunction and begin a previously announced turbine blade inspection as part of ongoing efforts to address turbine blade cracking as the plant finalizes long-term solutions, officials said.

Unit 1 is operating safely and is unaffected by the loss of the system on Unit 2, according to plant officials.

The Susquehanna plant is located in Luzerne County about seven miles north of Berwick.
