"SCRIBA, N.Y. — Officials at Constellation Energy are investigating a leakage in a containment structure that caused the shutdown of the Nine Mile Point Unit 2 reactor on Lake Ontario over the weekend.

The Oswego Palladium-Times reports that the reactor remained shut down Sunday after a “higher-than-normal leakage” was discovered inside the facility’s drywell. The incident was classified as an “unusual event,” the lowest level of nuclear power plant emergencies."

The Associated Press had the story August 8, 2011.
