The southeastern Pennsylvania nuclear reactor that unexpectedly shut down Monday night was returned to full power Friday, owner Exelon Corp. announced.
Repairs were made to a valve that closed automatically on one of the Limerick Generating Station Unit 1 reactor’s main steam lines, according to a news release from the company.
The valve closed due to a broken fitting, Exelon spokeswoman Dana Melia had said. The Unit 2 reactor at Limerick, in Montgomery County about 30 miles south of Allentown, was unaffected by Monday’s incident.

An unusual event is the first of the four emergency classifications established by the U.S. Nuclear Regulatory Commission for nuclear power plants.
“We will conduct a full investigation of this incident and make any necessary changes to be sure it does not recur,” Timothy S. Rausch, senior vice president and Chief Nuclear Officer for PPL Susquehanna, said in a press release.
The event had no effect on public safety and required no public action, according to PPL Corp., the Allentown company that partly owns and operates the plant.
