Energoatom said on social media that Russian agents “kidnapped” the plant’s assistant general director Oleg Osheka and head of information technology Oleg Kostyukov on Monday and “took them to an unknown place.”
Energoatom requested that Rafael Grossi, the director of the International Atomic Energy Agency (IAEA), “make every effort” to achieve their release.
In the early days of Russia’s invasion of Ukraine, in the beginning of March, Russian forces seized the Zaporizhzhia nuclear power station.
Russia has recently been under fire from Ukraine for allegedly holding many workers at the factory.
Energoatom said last week that Valeriy Martyniuk, the plant’s deputy director general for human resources, had been imprisoned and handled unfairly by Russia.
Since then, Martyniuk’s condition has not received any updates from the energy agency.
The agency said in late September that Ihor Murashov, the head of the power plant, was imprisoned by Russia for a number of days before being freed on October 3.
The nuclear reactor, which is the largest atomic facility in Europe, is situated in the Zaporizhzhia area of Ukraine, which is under Russian control and which Moscow says it has annexed together with the Ukrainian regions of Donetsk, Luhansk, and Kherson.
The shelling near the Russian-controlled plant has been the subject of months of blame-trading between Moscow and Kyiv. This has raised concerns about a nuclear disaster and sparked calls for demilitarising the region around nuclear facilities in Ukraine.
