Berwick (US): An energy company says it`s trying to figure out why a central Pennsylvania nuclear power plant reactor shut down unexpectedly.
PPL Corp says Unit 2 at the Susquehanna nuclear facility near Berwick shut down early Sunday morning. The company says the reactor is safe and stable.
In a statement, Allentown-based PPL says the shutdown occurred during routine testing of a valve on the unit`s main turbine system.
The company says the plant`s other reactor is operating normally.
The Susquehanna plant is owned jointly by PPL and Allegheny Electric Cooperative Inc.
