Sweden's Barsebäck nuclear power plant -- just 20 kilometres across the water from Copenhagen -- has long been the subject of bitter dispute over safety between the Danish and Swedish governments. Denmark's minister of the interior, Birthe Weiss, added new fuel to the dispute in February in a sharply formulated letter to the Swedish energy minister Jörgen Andersson. Referring to the Swedish energy commission's recent statement that the first nuclear plant will soon be closed -- a result of national policy to shut down all such plant in Sweden -- Weiss argued that Barsebäck is getting old, has suffered several technical faults and is the smallest atomic station in Sweden. For this reason it should be first on the list of plant to be stopped. Denmark also demands that Sweden accept unlimited responsibility for the effect on Denmark of any accident concerning Swedish nuclear plant.
