Severe storms and tornadoes moving through the Southeast dealt a severe blow to the Tennessee Valley Authority on Wednesday, causing three nuclear reactors in Alabama to shut and knocking out 11 high-voltage power lines, the utility and regulators said.
All three units at TVA’s 3,274-megawatt Browns Ferry nuclear plant in Alabama tripped about 5:30 EDT (2230 GMT) after losing outside power to the plant, a spokesman for the U.S. Nuclear Regulatory Agency said.
The NRC spokesman said early information indicated the units shut normally and the plant’s diesel generators started up to supply power for the plant’s safety system.
The government owned corporation said crews were working to restore service, but more severe weather was forecast, TVA said in a release. Most of the damage so far has occurred in the western part of TVA’s service territory in Mississippi, Alabama and western Tennessee and Kentucky.
