A valve on a recirculation pump was the cause of a leak in a containment structure which forced the shutdown of the Nine Mile Point Unit 2 reactor on Lake Ontario in Scriba, NY, over the weekend.

The “higher-than-normal leakage” was inside the facility’s drywell. Officials classified the incident as an “unusual event,” the lowest level of nuclear power plant emergencies.

The drywell is the containment structure surrounding the reactor vessel and associated piping, said Constellation Energy Nuclear Group spokeswoman Jill Lyon. She said the reactor will remain shut down until the necessary repairs and post maintenance testing are finished.

“The water that was leaking was contained within all the plant systems, and didn’t cause any concern for the folks that work here or in the surrounding community. Anything out of the ordinary is something we report.”
