The head of the International Atomic Energy Agency, Rafael Grossi, will visit Russia on Friday, the Interfax news agency reported on Thursday.
Grossi is likely to hold talks about the Russian-controlled Zaporizhzhia nuclear power plant in southern Ukraine.
Interfax cited Deputy Russian Foreign Minister Sergei Ryabkov as saying Grossi would hold talks with Alexei Likhachev, the head of Russia's state nuclear energy company Rosatom.
The meeting would take place in Kaliningrad, Russia's exclave on the Baltic coast between Lithuania and Poland, Ryabkov was cited as saying.
