TVA determines cause of arc flash at Tenn. nuke plant
An arc flash that burned two contract workers at the Sequoyah Nuclear Plant near Soddy-Daisy, Tennessee was not was not due to any equipment or plant-related issues, according to an investigation by the Tennessee Valley Authority (TVA). Instead, the TVA has concluded that the March 16 incident was caused by improper access and work in an electrical cabinet.
The workers, who were employed by Day & Zimmerman, were performing tasks near the cooling towers of the plant when the arc flash occurred. They sustained first- and second-degree burns and were transported to a local hospital.
