Susquehanna nuclear Unit 2 undergoing special inspection

The U.S. Nuclear Regulatory Commission (NRC) started a special inspection at the Susquehanna nuclear power plant in Pennsylvania on Jan 14 after an unplanned shutdown of Unit 2 on Dec. 19. Susquehanna is owned by PPL Corp (NYSE: PPL).

The three-member Special Inspection Team will evaluate the circumstances surrounding the shutdown, when the reactor was at 18 percent power as it was returning to service from an automatic shutdown that took place on Dec. 16. The inspectors will assess operator performance and management oversight, the company’s review of the event and the actions taken as a result of its review, the NRC said in a release.

The feedwater flow was temporarily lost when a valve failed to open as expected during startup, causing the plant to shut down. The feedwater system typically supplies water to the reactor vessel for steam production. The unit was restarted on Dec. 28.
