An accident at a nuclear power plant in Zaporizhzhya in southeastern Ukraine poses no danger to health or the environment, energy authorities said on Wednesday, an assessment later corroborated by the French nuclear institute IRSN.

Energy Minister Volodymyr Demchyshyn said the accident occurred Nov. 28 in one of the six blocks at Zaporizhzhya, Europe's largest nuclear power plant, and was caused by a short circuit in its power outlet system. The incident was "in no way" linked to power production, he told a news conference.

"There is no threat ... there are no problems with the reactors," said Demchyshyn, who took up his post in a new government only on Tuesday. He added that he expected the plant to return to normal operations on Friday.
