DTE Energy’s Fermi 2 nuclear power plant leaked 2,500 gallons of diesel fuel from one of its gas turbine generators Tuesday morning.
The leak occurred at 11:48 a.m. at the facility, located in Frenchtown Charter Township, MI, and spilled into an oil separator basin, according to a notification report by the plant.
No oil reached the ground or any navigable water, said Brian Kemker, Fermi resident inspector for the Nuclear Regulatory Commission (NRC).
Because of downed power lines, two generators had to be run to supply more power to the electrical grid as requested by the transmission operator, Kemker said.
Officials have yet to determine the cause of the leak, he said. Most of the spill ended up cleaned by Michigan Pollution Control on Tuesday and the NRC and Michigan Department of Environmental Quality received notification of the incident, the report said.
Kemker said the spill would not trigger any extra inspection for the plant, which is up for operating license renewal.
Its license expires in 2025. If the plant wins renewal, Fermi would be in operation until 2045.
