The International Atomic Energy Agency (IAEA) is concerned about the reduction in reactor cooling water available for nuclear plant in Zaporizhia, Ukraine after the destruction of a dam on the Dnieper River.

The IAEA said it is “closely monitoring the condition of the dike enclosing a large cooling tank due to increased pressure caused by massive water loss on its other side.”

The agency, which has stationed observers at Russian-held nuclear plantis monitoring the situation closely, IAEA chief Rafael Grossi said yesterday.

The destruction of the dam in the Kherson region, in the southern part of the country, on Tuesday resulted in tons of water flooding many areas under Ukrainian and Russian occupation. Huge amounts of water have spilled out of the Kakhovka reservoir, which may cause a serious problem for the Zaporizhia plant, located north of the dam.

Europe’s largest nuclear plant is not in immediate danger but the disaster “causes new major difficulties for the Zaporizhia Nuclear Plant at a time when the nuclear safety and security situation is particularly fragile and potentially dangerous during military conflict,” said Grossi.

“Increased military activity in the region heightens our deep concerns for its security.”
