The operators of the nuclear power plant in Ukraine’s Zaporizhzhia say that Russian forces are continuing to shell the site and that it is operating “with the risk of violating radiation and fire safety standards”. Energoatom says the plant has been damaged, and there are risks of “hydrogen leakage and sputtering of radioactive substances”. In response, Ukrainian officials have stepped up the safety drills and distributed potassium iodine tablets to the thousands of residents in areas, which can help protect the body in case of a radiation leak. A team of scientists from the United Nations’ International Atomic Energy Agency are set to travel to Zaporizhzhia – Europe’s largest nuclear power station – this week. Russia continues to deny that its forces are putting the plant’s safety at risk. On Saturday, it blocked the adoption of a joint UN declaration on nuclear disarmament over criticism directed its way.
