After a fire alarm sounded in a containment building at the Prairie Island Nuclear Generating plant near Red Wing, MN, operators shut down the Unit 2 reactor Thursday morning for what they are calling an “unusual event.”

The plant shut down after a fire alarm sounded in the unit two containment building shortly after 4 a.m. Prairie Island officials said there is no indication of a fire or any other dangerous situation but plant personnel are taking precautions to remove the unit from service to further investigate and address the issue.

They said the plant safely shut down and there was no release of radioactive materials as a result of this event. Additional details about the incident will be available after an investigation.

A notification of unusual event is the lowest of four emergency classifications established by the U.S. Nuclear Regulatory Commission (NRC).

The declaration indicates a potential reduction in the level of safety at the plant but no threat to public safety. The declaration’s purpose is to have the plant’s operating staff reach a state of readiness for emergency response if necessary.
