Major accident at the Sayano-Shushenskaya HPP Bashny.Net

Something recently frequent any accidents and disasters (((Sadly it all somehow ...

The incident occurred during the repair of one of the hydraulic units. According to recent reports, eight people were killed, eleven injured. All of them - employees of HPS.
The accident is the destruction. However, the authorities claim that the dam does not burst and the threat of flooding of settlements there.
"The situation is calm in the region, all problems are eliminated quickly," - said the head of the air in our Khakassia Viktor Zimin.
"The station is output in normal mode, began a planned discharge of water at the station there was a technical accident, the station is de-energized, but gidroinzhenernye facilities are in good condition, the floodgates opened, the station downstream villages threat can not be held, the sinking will not" - he said.
Meanwhile, in the settlements located far from the power plant, I started to panic. People on their own trying to leave the dangerous area. Also, leave the city and residents of Abakan, which is 140 kilometers away from hydropower plants.

Because of the accident at the Sayano-Shushenskaya hydroelectric power plant may be restrictions for consumers in the Altai Territory, in the Kemerovo region and the most Khakassia. In the Tomsk region has already started off, as long as it applies only to companies.
As for the causes of the accident, the experts called water hammer. Water hammer can occur at any hydropower plant - says the professor, vice-president of the Association "Hydroecology" Adolf Misha. According to him, to prevent a similar accident can be, but it is costly.
"Maybe some kind of partition wall, where a huge pillar of water can be destroyed, the flow velocity is huge, and on the way, encountering an obstacle formed that same hammer, where the pressure grows." He also said that to completely eliminate water hammer formation difficult. "If we seek, the construction cost will increase several times, so the design - it is rational to use within a reasonable actions that mitigate these catastrophic events," he said, "At the same time there are hydro power plants the risk of explosion of the hydrogen-air mixture, the probability is low, but it exists, "- said A.Mishuev.

Elimination of the consequences of the accident at the Sayano-Shushenskaya hydroelectric power station may take much longer than expected, - said the Minister for Emergency Situations Sergei Shoigu.
By order of the President, heads of Ministry of Emergency Situations and the Ministry of Energy poisoned Abakan to coordinate the aftermath of the accident. The President instructed the ministers to report on progress and provide the necessary assistance to the families of those killed and injured.
As a result of the accident at the hydroelectric power station in the Yenisei got technical oil. Spot dragged on for five kilometers, - the Ministry of Emergency Situations. According to the Ministry, a great threat to the environment there.

Sayano-Shushenskaya hydroelectric power station - one of the largest hydroelectric power plants in the world. Six years ago, experts say that its design is in need of modernization.
Sayano-Shushenskaya GES - Siberian giant appeared in the hot season the big Soviet construction projects. In autumn 1975 the whole Soviet Union watched as builders on BelAZazah dropping boulders into the river. "Wayward mighty Yenisei had to submit to the will of the people", according to historical information on the website of RusHydro. Romantic - in the spirit of those years - can be called a commitment to reduce the construction time and the quality of work performed. He gave numerous teams of different enterprises. During the construction of the power plant, scientists, and designers to skip the "big water" in the period of spring floods have designed a special device stilling. Later it turned out that the project made some mistakes. About this in an interview to "Rossiyskaya Gazeta" a few years ago told Senator Mezhevich Valentin, who has worked in the power industry for nearly thirty years. He recalled that the floods of 1985 and 1988 led to serious damage to the stilling basin. Both times it was necessary to carry out extensive and costly repairs. But the project failed to fix and failed. This conclusion is confirmed by a number of competent committees, who studied this problem since the days of the USSR Ministry of Energy, concluded Mezhevich. To increase the operational safety of a powerful hydraulic structure in 2003, it was decided to construct new facilities for the dam - a unique concrete arch design height of 245 meters and the crest length of more than a thousand meters. When RAO UES has existed to inspect hydro came Anatoly Chubais. He stressed that the modernization of the station - "this is not a business project, and the project, the question of security." The construction of a shore spillway planned to spend 5, 5 billion rubles. However, the date of completion of the project was listed in 2011.
Electricity power plant using several aluminum smelters, including Krasnoyarsk and Sayan.
