Xcel Energy terminates 'notification of unusual event' at nuclear plant

A decrease in water levels inside the reactor coolant system at Xcel Energy's Prairie Island nuclear power plant near Red Wing, Minn., prompted officials to declare a "notification of unusual event" earlier today.

The declaration has since been terminated.

The reactor coolant system is located in Unit 2 and is currently undergoing a refueling outage, Xcel Energy officials said in a statement. Unit 1 continues to operate at full power.

An investigation, which continues, showed there was no leak in the system, and plant operations weren't impacted, officials said.

This notification is the lowest of four emergency classifications set by the U.S. Nuclear Regulator Commission.

It indicates a possible reduction in the level of safety at the plant "but no threat to public safety," officials said.
