The information was shared by Mr. Alexei Likhachev, head of the Russian state-owned nuclear corporation, with TASS news agency on January 29.
Last year, President Vladimir Putin said that hundreds of Russians were working at the Bushehr nuclear power plant.
This is Iran's only operating nuclear power plant, built by Russia for Iran.
Russia is also building more nuclear facilities in the Bushehr area.
The US attack on Iranian nuclear facilities in June last year was not aimed at Bushehr.
At that time, Mr. Alexei Likhachev warned that an attack on this location in Iran could cause a disaster equivalent to the Chernobyl nuclear disaster in 1986.
On January 28, US President Donald Trump called on Iran to negotiate and reach an agreement to abandon nuclear weapons, otherwise the next US attack would be much worse.
We sincerely hope that the parties in the conflict will uphold their commitment to the inviolability of this territory (Bushehr).
But, as always said, we, in coordination with the Ministry of Foreign Affairs and the Ministry of Defense, are closely monitoring the situation and ready to take evacuation measures if necessary" - Mr. Alexei Likhachev emphasized.
