ATHENS, Alabama — TVA announced today it is replacing 100 emergency sirens in a 10-mile radius around the Browns Ferry Nuclear Plant near Athens, after 88 of the sirens went off-line last year during the April 27 storms.
The new sirens will still be powered by electricity, but will have a battery back-up. The failure of the sirens last year was attributed to a loss of power to the nuclear plant, which forced the plant into an emergency shutdown.
TVA said crews will be replacing four to six sirens a day beginning in late March. The crews will be working six days a week to finish the job by late spring.
The replacement will mean a number of siren tests.
TVA said sirens will be sounded multiple times a day, six days a week, for the next two or more months, until all sirens are replaced.
Upon completion of the Browns Ferry siren installation, TVA will then replace the sirens around its other two nuclear plants Sequoyah in Soddy Daisy, Tenn., and Watts Bar near Spring City, Tenn. TVA is investing about $7 million to replace the sirens.
