Unit 1 at Susquehanna nuclear plant shuts down safely

Operators at PPL’s Susquehanna nuclear plant near Berwick, Luzerne County, Pa., safely shut down the Unit 1 reactor Friday night (5/14) during equipment testing.

“During the refueling and maintenance outage that concluded last month, we made several equipment upgrades, including installing a new integrated digital control system for plant equipment and replacing turbines that power pumps providing water to the reactor vessel,” said Jeff Helsel, PPL’s Susquehanna plant manager.

“While plant personnel were performing a required test on the control system and the pumps, operators shut down the unit because established test limits were met,” he said.

All equipment responded to the shutdown as designed. There was no equipment damage.

“We have been performing a series of tests with the new control system to ensure the safety and reliability of the unit. We will complete an evaluation of the shutdown and have Unit 1 generating electricity again,” Helsel said.

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.

PPL Susquehanna is one of PPL Corporation’s generating facilities. Headquartered in Allentown, Pa., PPL Corporation (NYSE: PPL) controls or owns nearly 12,000 megawatts of generating capacity in the United States, sells energy in key U.S. markets and delivers electricity to about 4 million customers in Pennsylvania and the United Kingdom.
