The Fermi 2 plant in Monroe County is among 35 U.S. nuclear reactors being advised to test their ability to shut down automatically after an earthquake.
DTE Energy officials say the Fermi 2 reactor is routinely tested to make sure it's not susceptible to the problem.
GE Hitachi Nuclear Energy says the probability of a reactor not shutting properly is very low.
DTE spokesman Guy Cerullo says the utility "diligently" performs monthly control rod drive operability tests and quarterly tests in which all control rods are inserted at different times.
The Monroe Evening News reports Tuesday says it stays in close contact with GE and other nuclear energy facilities and that safety is its "number one priority."
