About 2,000 gallons is believed to have leaked from an oil cooling system on one of the two turbines at the Donald C. Cook Nuclear Plant in Lake Township near Bridgman.
The plant was at about 40 percent of power Tuesday morning.
Operators of the Palisades Nuclear Power Plant in southwestern Michigan say they removed it from service because of a water leak.
More work and hundreds of hours of additional inspections are planned over the coming year to help continue improving safety at the Palisades Nuclear Plant in southwestern Michigan, officials said.
A special federal inspection is planned of DTE Energy’s Fermi 2 nuclear power plant this year because the Monroe-area facility’s reactor was shut down too many times in 2012, officials said.
An environmental coalition is making more arguments against a proposed addition to DTE Energy Co.’s Fermi nuclear plant in southeastern Michigan.
A federal report is criticizing DTE Energy Co. for what it says are maintenance failures leading up to the June breakdown of a cooling water pump at the Fermi 2 nuclear power plant.
The U.S. Nuclear Regulatory Commission has found that environmental concerns are not significant enough to halt the construction of a proposed new reactor at the Fermi plant in Monroe County.
DTE Energy says it may take months before the Fermi 2 nuclear power plant returns to full power because of substantial repairs needed on a reactor water pump.
DTE Energy has shut down its Fermi 2 nuclear power plant near Monroe because of an excess of hydrogen gas in a cooling system for the main electrical generator.
