A total of 76 people are now feared dead following yesterday's accident at Russia's largest hydroelectric power plant.
The death toll from the disaster currently stands at 12, but hope is fading of finding a further 64 missing since one of the turbine rooms flooded at the Sayano-Shushenskaya plant.
'Finding anyone alive in the flood zone is unlikely, but the search continues,' said Vasily Zubakin, the chairman of state-run hydro-electricity company RusHydro.
Divers are still searching the flooded wreckage at the Sayano-Shushenskaya plant, but officials said that with water at just 4C, the chances of finding more survivors are low.
The components were undergoing repairs when the accident occurred, causing a large portion of the power unit to break off and puncture the ceiling and wall, allowing water to pour in and flood the chamber.
Three of the power plant's ten generating units were completely destroyed in the accident, however officials have insisted that there is no structural damage to the dam.
The power station is the most powerful in Russia and the fourth largest of its kind in the world.
RusHydro's shares are still suspended in Moscow after falling more than 15% in London on the previous day.
An investigation into the cause of the accident is under way.
