Injuries reported at Missouri nuclear power plant

Four people were injured this week at the Callaway nuclear plant in Missouri. One sustained only a minor injury and three were transported to a local hospital. No deaths were reported and all injured workers were conscious and walked away from the scene.

The accident, according to the Nuclear Regulatory Commission, occurred at 5:07 pm CDT on April 2, when an electrical “arc flash” occurred at a safeguards transformer in the plant switchyard. At the time of the flash, ground straps were being placed on the transformer, which had been removed for service maintenance. Some buildings outside the power block lost electricity, but there was no impact to equipment or systems at the plant, the NRC says.

The incident is the second serious personnel accident at a U.S. nuclear plant this week, after a piece of heavy equipment fell at a plant in Arkansas, causing injury to eight plant workers and the death of another.
