United Nations – The head of the United Nations atomic energy agency, the IAEA, is scheduled to visit Ukraine next week as a follow-up to his commitment last month to enlarge the watchdog agency's oversight of Ukraine's nuclear power plants, which have been shelled during Russia's nearly 11-month war on the country.Earlier this week, the agency conducted another rotation of IAEA staff at Zaporizhzhia (ZNPP), and next week the Director General will establish IAEA extended presence in all nuclear power plants under Ukraine control, at Ukrainian authority's request, according to a source familiar with the plans."These missions aim to provide technical support and assistance as needed in order to help maintain a high level of nuclear safety and security and reduce the risk of a nuclear incident or accident with a potential radiological impact on the population and the environment," the agency said, adding that Grossi was "continuing consultations with Ukraine and Russia aimed at agreeing and implementing a nuclear safety and security protection zone around the ZNPP as soon as possible.""Director General Grossi has repeatedly expressed grave concern about the impact of the challenging working conditions at the ZNPP," the agency said in its statement last week.Grossi has sounded alarm bells about Ukraine's nuclear plants since the summer, when he said about Zaporizhzhia: "Any military firepower directed at or from the facility would amount to playing with fire, with potentially catastrophic consequences.""
