Breach of Nova Kakhovka dam unleashes floodwaters

A strategically important dam in Russian-occupied southern Ukraine was blown up on Tuesday, raising fears about safety, water supply, and Europe’s largest nuclear power plant, which receives cooling water from the reservoir upstream.

Russian and Ukraine both accused each other’s forces of an intentional attack on the Nova Kakhova dam. CNBC has not been able to independently verify the claims.

Footage verified by NBC News showed water cascading over the damaged dam, with evacuation efforts underway to protect thousands of people living in low-lying areas downstream.

About 600 homes have been flooded as a result of the Nova Kakhova dam blast, Russian emergency services said, according to Tass news agency. Moscow declared a state of emergency in the Nova Kakhova district.

As of 11 a.m. local time (4:15 a.m. ET), 885 citizens in Ukraine’s Kherson region were evacuated, according to the Internal Affairs Ministry.

The dam is situated on the Dnieper River and holds back an enormous body of water. It was built in 1956 as part of the Kakhovka hydroelectric power plant.

The Kakhovka Reservoir supplies water to the Crimean Peninsula, which was annexed by Russia in 2014, and provides cooling water to the Zaporizhzhia nuclear power plant, which is also under Russian control.

In addition, its water is used to supply hydroelectric stations, irrigation systems, and freshwater fish farms.

Ukrainian President Volodymyr Zelenskyy said earlier Tuesday that he had convened an emergency meeting of the National Security and Defense Council to discuss the situation.

“The destruction of the Kakhovka hydroelectric power plant dam only confirms for the whole world that they must be expelled from every corner of Ukrainian land. Not a single meter should be left to them, because they use every meter for terror,” Zelenskyy said.

‘A crime of war’

The U.N.’s nuclear watchdog said it was closely monitoring the situation at Zaporizhzhia nuclear power plant. The International Atomic Energy Agency said via Twitter that it is aware of the reported damage at the dam, but there was no “immediate safety risk” at the plant.

Ukraine’s nuclear operator Energoatom said via Telegram that “the water level in the Kakhov reservoir is rapidly decreasing, which is an additional threat” to the nuclear power plant, according to a translation.

“Water from the Kakhovka Reservoir is necessary for the station to receive power for turbine capacitors and safety systems of the ZNPP. The station’s cooling pond is now full: as of 8:00 a.m., the water level is 16.6 meters, which is sufficient for the station’s needs,” the agency said.

The Conflict and Environment Observatory, a non-profit based in the U.K., said the Kakhovka Reservoir is known to be the “ultimate heat sink” for the Zaporizhzhia nuclear power plant, noting that it can remove heat from shutdown reactors and spent fuel pools. It warned the breach of the dam posed a “serious threat” to the plant.

German Chancellor Olaf Scholz said his government was also monitoring the status of Zaporizhzhia nuclear power plant following the dam’s breach, while Lithuanian President Gitanas Nauseda¬†described the destruction of the infrastructure as “a crime of war that directly threatens thousands of people.”

Half the span of the Nova Kakhovka dam appears to have been destroyed and Tass reported that the structure is continuing to collapse, citing emergency services.

Meanwhile, a Russian-installed official in the Ukrainian town of Nova Kakhovka reportedly said in comments to state television that the dam would be impossible to repair.
