Two contract workers were burned from an arc flash while working near the cooling towers of a Tennessee Valley Authority nuclear plant over the weekend.
The workers employed by Day & Zimmerman at the Sequoyah Nuclear Power Plant near Soddy-Daisywere hospitalized Friday night for first- and second-degree burns.
The Nuclear Regulatory Commission said in an incident report that both workers were transported to a hospital for treatment. Neither worker was shocked nor contaminated by any radiation from the 6.9 kilovolt electrical bus they were working on during the accident.
“The cause of the arc flash is not understood at this time; an accident investigation has been initiated by TVA,” the NRC said in its report on the incident.
TVA spokeswoman Malinda Hunter said Monday that TVA is investigating the incident, which occurred in the non-nuclear part of the plant and did not jeopardize operations of either of the power generating reactors.
