Entergy brings nuclear unit back online after fatal accident

Arkansas Nuclear One ANO Unit 1 returns to service Unit 2 fatal accident generator stator Entergy

Arkansas Nuclear One’s Unit 1 was brought back to service after it was damaged during a fatal accident at the plant.

The plant entered a scheduled refueling outage on March 24. During the outage, a contractor’s crane collapsed while moving a generator stator out of the turbine building. One worker was killed and eight others were injured.

Unit 1 required extensive restoration efforts, including damage evaluation, repairs to non-nuclear plant components and rescheduling refueling activities, plant owner Entergy (NYSE: ETR) said in a release.

Unit 2 automatically shut down during the accident as it was designed to do and was brought back to service in April after extensive evaluations.
