This occurred due to a transformer shutdown caused by contact between a worker and a cable during installation work. The emergency diesel generators were subsequently activated, immediately supplying power to the plant, and the injured worker received first aid before being transported to a specialized hospital.

Currently, Wolsong Unit 1 remains permanently shut down, and Wolsong Unit 3 has been undergoing scheduled preventive maintenance since May 1. The Wolsong Nuclear Power Headquarters is investigating the detailed cause of the incident.
