Valve maintenance on PA nuclear plant

Unit 1 at PPL’s Susquehanna nuclear plant in Luzerne County, Pa., returned to safe and reliable electricity generation Thursday March 10 after maintenance work on a valve was completed. The valve is part of a backup system that can provide cooling water to the reactor in the unlikely event normal systems became unavailable. The valve is in an area of the plant where work can be done only when the plant is shut down. Operators at the plant had safely shut down the Unit 1 reactor March 4. In addition to working on the valve, plant personnel did a number of other maintenance tasks that can only be done when the unit is shut down.
