Unexpected shut down at Susquehanna nuclear Unit 2

PPL Susquehanna nuclear power plant Pennsylvania shut down

Reactor Unit 2 at the Susquehanna nuclear plant in Pennsylvania experienced an unexpected shutdown early Sunday morning, according to PPL (NYSE: PPL).

All safety systems responded as expected and the reactor is safe and stable, PPL said in a release. The shutdown occurred during a routine test of the No. 2 control valve on the unit's main turbine system per the station's surveillance testing program, according to a report from the Nuclear Regulatory Commission.

"We regularly test and evaluate the condition of plant systems and equipment," said Timothy S. Rausch, PPL Susquehanna senior vice president. "The Unit 2 reactor automatically shut down during one of these planned tests. Our operators followed established procedures to keep the unit in a safe and stable condition."

Unit 1 has continued operating at full power without incident. PPL is currently investigating the exact cause of the shutdown.
