The risk of a disaster at a nuclear power plant in Ukraine due to fighting or the loss of external power remains high despite the threat having fallen from the headlines, the head of Germany's Federal Office for Radiation Protection said. Inge Paulini said there is considerable risk of an accident occurring that has far-reaching consequences as long as the war continues. Apart from a direct attack on a plant, Paulini said the risk associated with power supply failures is among her top worries.
