The ex-head of Russia`s now defunct state electricity monopoly said on Sunday that the findings by the industrial safety watchdog fully reflected technical causes of a recent disaster at the country`s largest hydropower plant. Rostekhnadzor announced on October 3 the results of a probe into the causes of the August 17 disaster at the Sayano-Shushenskaya hydroelectric power station that destroyed a turbine hall and killed 75 people. Rostekhnadzor said Anatoly Chubais was among those responsible for the accident. "I believe that Rostekhnadzor`s conclusions reflect fully enough direct technical causes of the disaster. As for my responsibility, I am responsible for everything that was happening in the sector when I was in charge of it. And the death of 75 of my fellow power engineers is a severe tragedy for me personally," Chubais said. Chubais admitted on Saturday he was obliged to commission the country`s largest hydropower plant in 2000 despite problems that might have caused its recent wreckage. "I believe I was obliged as the head of UES of Russia to sign an acceptance report for the Sayano-Shushenskaya plant in 2000," Chubais told RIA Novosti. He admitted that energy producers were then facing high risks over a lack of funding. However, Chubais said, suspending the Sayano-Shushenskaya hydropower plant that started operating on Siberia`s Yenisei River in the 1970s, over a lack of investment in the replacement of hydraulic wheels "would have been a catastrophe to the Siberian economy and millions of people living there" back nine years ago. Chubais, who has held a number of influential posts since the 1990s but has always been unpopular with public, was appointed head of Russia`s State Nanotechnology Corporation last September.
