VIENNA (Reuters) - The Russian-held Zaporizhzhia nuclear power plant in Ukraine could come back online within months of a ceasefire, but it would probably take more than a year to restart all six reactors, the U.N. atomic watchdog chief said on Wednesday.

Russia's Ministry of Foreign Affairs has stated that Moscow "does not consider it possible" to transfer control of the temporarily occupied Zaporizhzhia Nuclear Power Plant (ZNPP) to Ukraine or any other country.

Russia's Foreign Ministry said on Tuesday the Zaporizhzhia nuclear plant was a Russian facility and transferring control of it to Ukraine or any other country was impossible. The ministry also said that jointly operating the plant was not admissible as it would be impossible to properly ensure the physical and nuclear safety of the station.
