The Mykolaiv region has been under constant shelling in recent weeks, following Putin’s army suffering heavy losses from Ukraine’s counterattack. The latest nuclear catastrophe fears come after Europe’s largest nuclear power plant, Zaporizhzhia, was shut down earlier this month following Russian shelling. The Zaporizhzhia plant, located 250 km from Pivdennoukrayinska, is held by Russian troops but operated by Ukrainian personnel. The head of the UN nuclear agency Rafael Grossi warned that the “physical integrity” of the nuclear power plant had been “violated several” times by shelling during the invasion of Ukraine. Grossi was part of a 14-strong UN delegation that visited the plant in early September. Ukraine has 15 nuclear reactors spread throughout the country, which provide half of its electricity.
