ATHENS, Ala. (AP) — The Tennessee Valley Authority is turning up the volume on warning sirens near the Browns Ferry Nuclear Plant.
The federal utility says it is increasing the volume of 100 emergency sirens near the plant to improve notification capabilities during an emergency.
TVA says it's also adding four new sirens within the 10-mile emergency zone around the plant, which is located on the Tennessee River near Athens.
Browns Ferry has been under increased scrutiny by federal regulators because of problems with a cooling system that went unnoticed for an extended period. Violations have earned it some of the worst ratings among U.S. plants overseen by the Nuclear Regulatory Commission.
Plant officials say they're working to correct problems. They say public safety isn't at risk.
