Limerick Reactor Shut Down After Valve Closure

One of Limerick Generating Station’s two nuclear reactors has been taken offline after a valve closure.

Unit 1 was automatically taken offline around 9:40 p.m. Monday after a valve on one of the main steam lines closed, officials told The Philadelphia Inquirer, adding that all the equipment responded as it was supposed to.

There should be no impact on customers, The Reading Eagle said.

Officials on Tuesday morning were trying to determine what caused the valve closure, the Inquirer said.

Limerick Generating Station, about 20 miles outside of Philadelphia, produces enough power for 2 million homes, parent company Exelon Corp. said.
