Operators at PPL's (NYSE: PPL) Susquehanna nuclear power plant disconnected Unit 1 from the regional electric grid Saturday (12/13) because of a small water leak inside the containment structure. The massive concrete containment structure, which surrounds the reactor, is not accessible when the unit is running.
Although the water leak is well within the plant's limits for continued safe operation, operators began shutting the unit down as a conservative measure to complete repairs and enhance the unit's reliability for the upcoming winter, when cold weather drives higher electricity use.
PPL Susquehanna expects to quickly identify the source of the water leak, complete repairs and resume generating electricity for the regional power grid.
The Susquehanna plant, located in Luzerne County about seven miles north of Berwick, is owned jointly by PPL Susquehanna LLC and Allegheny Electric Cooperative Inc. and is operated by PPL Susquehanna.
