COVERT TOWNSHIP, Mich. (WOOD) - Palisades nuclear power plant will completely replace the bottom of a leaky 300,000-gallon water tank that has been responsible for several shutdowns since late 2011.
The Covert Township plant most recently shut down on May 5 when a crack in the tank allowed 79 gallons of "slightly radioactive water" to flow in to a pond that feeds directly into Lake Michigan. There was no public health threat.
Monday, the plant said it would completely replace the tank bottom and reconstitute the tank's subflooring. Plant spokeswoman Lindsay Rose said in a statement that "by replacing the tank bottom, we can return the subflooring to its original condition."
That leaky tank sits right above the plant's main control room. In the past year, it has accounted for one third of the plant's shutdowns:
- June 2012: Water tank leak
- August 2012: Rod housing leak
- November 2012: Steam leak
- November 2012: Valve leak
- February 2013: Tube leak
- May 2013: Water tank leak
The plant has shut down nine times since 2011.
The extensive renovations to the tank will likely take until early summer to finish.
"We are confident this very conservative approach will bring this issue to final resolution," Rose said in the statement.
The plant will remain offline for the duration of the repairs, Rose told 24 Hour News 8.
