A nuclear power plant in southeastern Michigan remains shut down after a valve issue was discovered following the malfunction of a transformer.
DTE Energy says Fermi 2 in Monroe County remains in a "safe, stable condition."
Spokesman John Austerberry tells the Monroe News that the utility completed its investigation into the transformer malfunction but stayed offline after an inspection found the valve issue.
Austerberry says the valve is on the reactor recirculation system.
The newspaper says the transformer problem appears to have been caused by water in a breaker associated with the transformer.
Fermi 2 supplies 20 percent of the electricity generated by DTE, but the utility can get power from its other generating stations and, if necessary, a regional energy market.
