NRC sends inspection team to Palisades Nuclear Power Plant
Palisades Nuclear Power Plant was shut down this past Sunday for a water leak inside a containment building. This is the second leak at the plant this summer that has triggered a shutdown.
The plant is operated by Entergy Nuclear Operations and is located in Covert, Michigan near South Haven.
Today, the Nuclear Regulatory Commission announced that a three member inspection team is at Palisades looking into the problem:
The three member inspection team will begin work Wednesday and look into the circumstances surrounding the leak. They will review the utility’s monitoring of the leak and subsequent plant shutdown, verify the adequacy of radiological controls, evaluate any potential degradation, and review the plant’s repair actions. The team will also review the plant’s reporting requirements and their plan for addressing the cause of the event.
Michigan Radio's Lindsey Smith covered the shutdown in yesterday's Environment Report segment. She spoke with Entergy spokesman Mark Savage.
Savage says they’ve determined that a “control rod drive package” is the source of the leak. There are 45 of these control rods. Plant operators can raise or lower control rods to control the rate of the nuclear reaction. “And occasionally these control rod drives will have a problem. In this case we couldn’t identify it until we actually shut the plant down. So we take aggressive action to shut the plant down, do the right thing, make the repairs and return the plant to service," Savage said.
Palisades has been the focus of significantly more oversight from federal regulators over the last year.
