Officials at the Prairie Island nuclear power plant are investigating what it calls an "unusual event" after a piece of security equipment failed Wednesday afternoon, according to a news release. Xcel Energy said no radioactive material was released during the incident and there is no danger to the public or its workers.
One of the twin reactors at Prairie Island was shut down last month for refueling and other maintenance, the Pioneer Press reports. The scheduled outage is expected to last four to six weeks.
Meanwhile, Minnesota's Public Utilities Commission has agreed to let Xcel Energy to drop the $237 million upgrade at its Prairie Island nuclear power plant near Red Wing, the Star Tribune reports.
Last month, the Minneapolis-based utility said the power-boosting project was no longer a good deal for customers.
