VAN BUREN COUNTY Workers at the Palisades Nuclear Power Plant stumbled into fresh insight into safety conditions at the plant.
For more than four decades, the plant's water tank was believed to be sitting on a large bed of sand, for safety reasons. But this week, investigators found that that's not the case.
WSJM reports that Entergy has been repairing a leaking tank over the control room. During their work, they found that Consumer Energy didn't follow the building plans back when the plant was constructed.
A spokesman for the Nuclear Regulatory Commission says they're working to fix the problem by putting in a fiber board, reinforced with asphalt.
The discovery followed a small leak last week. About a half cup of water seeped into the control room over the course of several hours.
