TVA Nuclear Sirens Sound During Annual Maintenance

Oct 13, 2020

CHATTANOOGA, Tenn. – The Tennessee Valley Authority is conducting annual maintenance on the nuclear sirens in the 10-mile radius of the Sequoyah Nuclear Plant through the end of October.

Area residents can expect to hear the full test of a three-minute sounding, which is normally heard the first Wednesday of each month at noon, followed by additional shorter soundings as the maintenance teams ensure the sirens are working as designed. Sirens are tested individually following maintenance activities over the next three weeks, and all sirens will not sound at the same time.

If you hear a siren, turn on your radio or television and listen for instructions. If there is emergency information, WUSY-FM (100.7) in Chattanooga is the primary emergency alert system station in the area and is monitored by other stations.
