‘The defunct site of the infamous 1986 meltdown has lost power two weeks after it was seized by Russian forces. Experts fear another nuclear disaster looms.

Two weeks ago, Russian forces seized control of the defunct Chernobyl, once the site of the world’s worst nuclear meltdown, and Zaporizhzhia, Europe’s biggest active nuclear power plant, raising concerns of nuclear risks in the middle of a war zone. 

Although Chernobyl’s last reactor went offline in 2000, the site now serves as a nuclear waste storage facility—and a highly contaminated one. The situation there is deteriorating; the facility lost power on Wednesday, and backup diesel generators have only enough fuel for two days. The 210 technical personnel and guards have not been allowed to rotate out to rest. The UN’s International Atomic Energy Agency, which promotes the peaceful use of nuclear energy and prevents nuclear weapon proliferation, says it lost contact with Chernobyl’s radiation monitoring systems on Tuesday. Unless officials can restore power, experts fear Chernobyl could once again become the site of a nuclear calamity.

“To have a long-term loss of power is certainly a concern,” says Ed Lyman, a senior global security scientist at the Union of Concerned Scientists and coauthor of the book Fukushima: The Story of a Nuclear Disaster. Some of Chernobyl’s waste has been transferred into dry casks, but considerable quantities of fuel rods remain in a pool that requires cooling. That’s where the biggest risks currently are. “Without electrical power to the cooling pumps, the spent fuel pool will start heating up,” Lyman says. Water will gradually evaporate or boil away, exposing the fuel rods and releasing radioactive gasses….’
