UN nuclear watchdog chief in Ukraine to provide 'urgent technical assistance'

U.N. nuclear watchdog’s director-general arrived in Ukraine Tuesday ahead of talks with senior government officials on delivering "urgent technical assistance."

It said that Grossi will travel to one of Ukraine’s nuclear power plants this week, but didn’t say which one. Ukraine has 15 nuclear reactors at four active power plants, and also is home to the decommissioned Chernobyl plant, the site of the 1986 nuclear disaster. Russian forces have taken control of Chernobyl and of the largest active power plant, at Zaporizhzhia.
