The Freon was safely removed from a chiller in the Unit 1 reactor building and placed in storage tanks on site. Freon is used as a refrigerant in the air-conditioning system for the reactor building and provides cooling for plant equipment in the reactor building, the company said.

Miriam Mylin, spokeswoman for Susquehanna plant, said: “While public safety was not at risk during this situation, entering the emergency management plan —which involves cooperation from many municipal, county and state agencies — ensured we had the resources available if needed to help protect employees and support the safe operation of the plant. We appreciate the support of those agencies.”

Both generating units at the plant are operating at full power.

The Susquehanna plant, located about seven miles north of Berwick, is owned jointly by PPL Susquehanna and Allegheny Electric Cooperative and is operated by PPL Susquehanna.
