A nuclear expert has expressed his concern as Russian forces are attempting to take control of the power stations in Ukraine as part of their illegal invasion.
Russia currently has control of two plants - one being Zaporizhzhia nuclear plant in the southeastern city of Enerhodar, the biggest nuclear power plant in Europe.
The other is Chernobyl, which is not active but is still staffed and maintained.
The fighting at the Zaporizhzhia plant caused immense worry around the globe, particularly after a fire broke out at a building beside the reactor itself.
Professor Tom Scott of Bristol University explained to RTE Morning Ireland the situation as it stood now.
He said: "It's a silly thing to have done by the Russians, but at least now the risk of a nuclear incident is much lower as the station has been taken under control and there is no longer fighting at this point.
"However, the workers are being held there and forced to work without ability to swap shifts, so they'll be tired, stressed - they need to work with independency, when they're tired, they can make mistakes like the rest of us.
Mr Scott also noted that the battles are not over, with three other power stations the target for the Russians.
"They are after the energy infrastructure for Ukraine. The Ukrainians want to keep their lights on and telecommunications working, the Russians want to take it away from them, so it was unsurprising to see the power station as a battle zone - but that breaks international convention. If a shell had gone loose and hit the power building, it could've been a lot worse.
"There are three more possibilities of things going bad."
Ukraine has four nuclear plants with a total of 15 reactors.
The three that remain in Ukrainian control are South Ukraine, Rivno in the north west and Khmelnitsky in the west.
