The International Atomic Energy Agency (IAEA) is working to restore offsite power to the Zaporizhzhya nuclear power plant in southeastern Ukraine, the head of the UN agency said on September 30. Ukrainian President Volodymyr Zelenskyy said earlier that the situation at the power plant had become critical after entering the seventh day of an emergency. IAEA representatives at the power plant confirmed that emergency diesel generators had begun operating to provide the plant with electricity. Zaporizhzhya, Europe’s largest nuclear plant, was seized by Russian troops shortly after Moscow launched its full-scale invasion in February 2022. The IAEA has played a role in safeguarding the condition of Ukraine's nuclear power plants, and inspectors from the agency are on site to monitor safety.
