Sweden’s Internal Security Agency announced on Monday that it had taken over an investigation into last week’s flight of drones hovering over the country’s three atomic power plants.
At first the police said there were drones over two nuclear plants – Forsmark, north of Stockholm, and Oskarshamn in the southeast.
The intelligence service “SAPO” said that a drone was also reported at the third Ringhals nuclear power plant, the largest of which is located on the west coast of the country.
He added: “With regard to the cases of drones flying at three nuclear power plants, it was assessed that they were of such a nature that preliminary investigations should be withdrawn from the police authority in order to be able to investigate the incidents in more detail.”
Hans Lewang, associate professor at the Swedish National Defense College, said Sweden was not adequately prepared for this type of event.
“We haven’t really adapted our way of looking at this kind of event to today’s reality… We still believe that the world is either at peace or at war,” he said.
It is reported that in 2019, the Ringhals 2 reactor in southwest Sweden was permanently closed due to its lack of revenue and high maintenance costs.
There are two out-of-service nuclear plants in Sweden: Barsbach on the narrow waterway between Sweden and Denmark, and Agusta, south of the capital, Stockholm.
