Federal regulators are examining a nuclear plant in northeastern Pennsylvania following three unexpected shutdowns.
The Nuclear Regulatory Commission sent an inspection team to the Susquehanna power plant on Monday.
The most recent shutdown occurred Dec. 19 after a valve failed to open during plant startup. Officials say that temporarily interrupted the water supply to one of the plant’s two reactors.
A commission statement says while that posed no immediate safety threat, the shutdown raised questions in the wake of unplanned shutdowns on Nov. 9 and Dec. 16.
The power plant near Berwick is operated by Allentown-based PPL Corp. A PPL spokesman says the plant was always in a stable and safe condition.
The nuclear agency says its inspection will focus on operator performance, equipment reliability and decision-making.
