Deadly Blast at Russian Hydroelectric Plant in Siberia
MOSCOW - Teams of divers scoured areas around Russia's largest hydroelectric plant on Tuesday but the plant's owner said it was doubtful that any of the 64 workers missing after an accident would be found alive.
"With every hour there is less and less chance left that we will find somebody alive," RusHydro spokesman Yevgeny Druzyaka told The Associated Press.
Monday's accident during repairs at the massive Sayano-Shushenskaya plant in southern Siberia drowned or crushed at least 12 workers and shut down electrical supplies to a wide region. Two workers were found alive Monday in niches inside the flooded structure, RusHydro acting chief Vasily Zubakin was quoted as saying by the ITAR-Tass news agency.
Federal investigators said an explosion destroyed walls and the ceiling in an engine room where turbines are located and caused the room to flood. One of the plant's 10 turbines was destroyed, two were partly destroyed while three others were damaged, officials said.
The plant's dam, a towering structure that stretches a kilometer across the Yenisei River, was not damaged and towns downstream were not in danger, Emergency Situations Minister Sergei Shoigu said.
Knocking sounds
Regional Gov. Viktor Zimin refuted allegations that rescue teams had heard knocking sounds from inside the plant's structure as if workers trapped inside were calling for help. He said the dam's thick concrete walls would muffle any sounds from inside, Russian news reports said.
Former plant director Alexander Toloshinov, however, said some workers trapped in the flooded control room could have survived by finding a corner with some air left.
Three groups of divers were searching for the missing workers both inside the flooded rooms and in the Yenisei river outside, Shoigu said in televised comments, adding that the workers are now believed to have drowned or been crushed by the debris.
The accident shut down the power plant, located 2,050 miles east of Moscow, and left several towns and major factories without electricity on Monday. Supplies from other power plants were being rerouted Tuesday to help cover the shortfall.
It still was unclear how long other power plants would be able to continue making up for the energy shortage. The plant satisfies 10 percent of Siberia's energy needs, according to Russian media reports.
The accident also produced an oil slick that by Tuesday stretched over 50 miles downriver. Crews were struggling to stop it but so far had not.
Faulty turbine to blame?
RusHydro said a faulty turbine at the plant, which began operating in 1978, was likely to blame. Investigators believe the accident occurred after a defective lid of one of the plant's 10 turbines got torn off during repair work, Vishnyakova, the RusHydro spokeswoman, told the AP.
Shoigu, however, said later that was merely one of several theories why the accident occurred, Russian news agencies reported.
RusHydro said replacing the damaged equipment at the plant may take up to two years but the undamaged turbines could be put back into operation in as soon as a month.
Shoigu said the repairs would be difficult.
