The Decatur Daily (http://bit.ly/GXNF9v ) reports that the work will cost about $2.3 million total. The sirens are being replaced within a 10-mile radius of the plant, located near Athens.
The sirens are used for both weather warnings and nuclear emergencies.
Numerous sirens failed during the April 27 tornadoes last year because they relied on the power grid for operation. The tornadoes downed power lines in three counties and forced a shutdown of Browns Ferry.
The loss of power not only disabled the sirens, it disrupted cooling systems for spent radioactive fuel in on-site pools at Browns Ferry.
The new sirens have battery backups and steel poles, making them less likely to fail.
