Alabama Power has lifted an alert caused by a carbon dioxide leak at a nuclear power plant.
The utility said the alert was lifted Saturday at 11:10 a.m., about five hours after it was first declared.
Alabama Power spokesman Ike Pigott said the carbon dioxide release was detected in an auxiliary building of the Unit 1 reactor at Plant Farley. The leak was then contained.
It appears the gas came from a fire suppression system, though no fires were detected. Pigott said the volume of gas was equivalent to what might be released from a large fire extinguisher.
