The nuclear safety and security situation at Ukraine’s Zaporizhzhia nuclear power station remains extremely fragile with “very real” potential danger of a major accident, International Atomic Energy Agency director-general Rafael Grossi told the United Nations Security Council ahead of his fourth mission to the site early next month.

Grossi announced he would cross the frontline to travel to the Zaporizhzhia facility “within the next two weeks”, enabling him to assess the situation there first-hand some eight months after his previous mission to the station.
