Solar powered warning sirens to be installed at Browns Ferry Nuclear Plant
Sirens are meant to alert people around in case of an emergency. However, when electricity fails in such emergency situations, these sirens are rendered useless without proper backup. Keeping this in mind, the Tennessee Valley Authority has planned to install solar powered sirens at the Browns Ferry Nuclear Plant that will scream out loud, even without grid power supply. Using a DC battery backup as well as a solar powered backup system, backup systems will be installed at three facilities at the cost of $7 million with the sirens finally being fitted into place by March 2012.
A great way to avert disaster, particularly given the fact that this plant is in the tornado-prone area that usually faces electricity issues during stormy weather, these solar powered sirens will alert people around in a green way.
