A serious workplace accident occurred at the Forsmark nuclear power plant, involving a young man in his 20s who was performing welding work.

The incident took place on Friday morning at Forsmark's third reactor, which is currently shut down for annual maintenance.

The man was severely injured and transported to the hospital by air ambulance.

The police were notified of the accident six hours later, which is unusual, and they are investigating the delay.

The site has been cordoned off, and a technical investigation is scheduled.

An inquiry into potential workplace safety violations and bodily harm has been launched.

Forsmark has halted similar welding activities and is providing crisis support to affected staff.
