Swedish Nuclear Incident "Worst ever."
Sweden’s emergency shutdown of a nuclear reactor at the end of July was the Scandinavian country’s worst nuclear incident.
That’s according to Björn Karlsson, the chair of the safety body that advises the Swedish nuclear power inspectorate.
”There are four ... independent safety systems, and in this case two of them failed. This is considered as the most serious fault in the industry,” Karlsson said.
The Forsmark 1 reactor was shut down after a short-circuit caused a blackout. Two of four backup diesel generators failed to start automatically, revealing other faults in the power station’s electrical system.
Karlsson was commenting on a technical report compiled by Forsmark staff published on Monday. According to him, information contained in the report shows the incident at the plant was the most serious in the history of Swedish nuclear power.
SKI was forced to halt operations at three other of the country’s 10 reactors after the incident at Forsmark.
The body on thursday played down the significance of the incident, although the four power plants hit by the shutdown remain off-line.
