Ukraine warns of radiation risk after power cut at Russia-occupied Chernobyl plant
Ukraine warned Wednesday that electricity has been entirely cut to its Chernobyl nuclear power plant and radioactive substance could be released because its storage facility cannot cool spent nuclear fuel.
The Chernobyl Exclusion Zone, a 1,000-square-mile restricted area of deserted land surrounding the shuttered plant, was seized by Russian forces just hours after they launched their invasion on Feb. 24. The plant, situated between the Belarus-Ukraine border and the Ukrainian capital, Kyiv, is the site of the world's worst nuclear disaster in 1986.
Ukraine's State Service of Special Communications and Information Protection announced via Twitter on Wednesday that the "Kyiv high-voltage line is currently disconnected due to the damage caused by the occupiers."
"As a result, the Chernobyl station and all nuclear facilities in the Exclusion Zone are without electricity," the agency tweeted.
Ukrainian Foreign Minister Dmytro Kuleba also confirmed the news on Twitter, saying the only electrical grid supplying Chernobyl and all its nuclear facilities occupied by Russian forces "is damaged," causing a loss of power supply.
"I call on the international community to urgently demand Russia to cease fire and allow repair units to restore power supply," Kuleba tweeted.
However, the International Atomic Energy Agency (IAEA) said it "sees no critical impact on safety." The nuclear watchdog of the United Nations tweeted that the "heat load of spent fuel storage pool and volume of cooling water" at Chernobyl is "sufficient for effective heat removal without need for electrical supply."

Some 20,000 spent nuclear fuel assemblies are stored in Chernobyl's storage facility and "need constant cooling," which is only possible if there is electricity, according to Ukraine's State Service of Special Communications and Information Protection.
"If it is not there, the pumps will not cool. As a result, the temperature in the holding pools will increase," the agency tweeted. "After that evaporation will occur, that will lead to nuclear discharge."
Kuleba noted that reserve diesel generators have a 48-hour capacity to power Chernobyl.
"After that, cooling systems of the storage facility for spent nuclear fuel will stop, making radiation leaks imminent," he tweeted. "Putin's barbaric war puts entire Europe in danger. He must stop it immediately!"
Ukraine's State Service of Special Communications and Information Protection warned that "the wind can transfer the radioactive cloud" to other areas of Ukraine as well as Belarus, Russia and elsewhere in Europe. There is also no ventilation inside the Chernobyl storage facility.
"All personnel there will receive a dangerous dose of radiation," the agency tweeted.
Meanwhile, the facility's fire extinguishing system is not functioning and the agency warned of "a huge risk of fire caused by shelling."
"The fight still goes on making it impossible to carry out repairs and restore power," the agency tweeted.
