The dam provides water both for the irrigation of the region and for the irrigation of Crimea, as well as for the hydroelectric power plant, but also for the Zaporozhye nuclear power plant, he said, stating that the United States was relieved to receive the news from the director of the International Atomic Agency that there was no immediate risk to the safety of the nuclear.
