Located on the Yenisei River, nearest to Sayanogorsk in Khakassia, Russia, the Soviet-era Sayano-Shushenskaya Hydroelectric Power Station was opened in 1978. By 2009, the plant was ranked sixth in the world and first in Russia for gross hydroelectric power generation. A total of ten turbines were utilized to provide 6,400 MW of electricity to the Russian infrastructure.1
As workers arrived to the plant around 08:00 h on 17 August 2009, there was no cause for immediate alarm. Of the ten turbines, nine of them were running with a tenth down for routine maintenance. Turbine two, however, was causing significant vibrations as its load varied with electricity demand. At 08:13 h, vibration of the turbine bearing reached a maximum and caused a catastrophic failure. The turbine cover shot up as the 1,000 t rotor shot off of its seat. The newly created hole in the structure allowed water to surge at a rate of 67,600 gal s-1 into the machinery hall and flood the levels below.2 The massive jet of water ripped apart the metal joists which held up the roof over turbines one, two and three. As the roof came down, water continued to flood the plant. Long after the automatic safety system should have been triggered, turbines seven and nine still operated at full speed, causing what were witnessed as large explosions in their vicinity as flooding reached their control panels.
Luckily, by 09:20 h the 170 t steel water intake gates to each turbine were manually closed using relief valves on each gate's hydraulic support jack. At 11:32 h a diesel generator was brought in to restore power to the area. Later, at 11:50 h, 11 spillway gates were opened to relieve excess ...

...ing is also taught here, as workers at the plant had never completed any emergency drills and no backup generator was installed to provide power to the plant itself in the case of an emergency.
Much of the reason for turbine two's failure, however, rests in the hands of man. The maintenance and inspection personnel clearly knew that the intense vibrations were not normal, but still the turbine was used. This could also have fallen back to management, as they should have ensured that maintenance directives were being followed. In relation to this it should be noted that directly following the explosions as many people were fleeing, several supervisors in charge of safety and emergencies also fled.
Ultimately, this was an entirely preventable disaster brought on by human negligence, exacerbated by mechanical fatigue and ended with lessons learned at a steep price.

- When people hear the word “nuclear” immediately they think of the nuclear bomb. Why. Because that is the only thing world governments talk about, is how they tested such bombs and how powerful they are. But, those people may not think that some of the electronics they use at home are powered by nuclear energy. Many oppose the use of nuclear energy saying it is too harmful. On the other hand, I support nuclear energy and how useful it is to the planet. The USA is responsible for creating the first commercial pressurized water reactor called “Yankee Row,” which started in 1960.... [tags: Nuclear power, Nuclear fission]

- Introduction: Sayano – Shushenskaya Hydroelectric power station is located on the Yenisei River, near Saynogorsk in Khakassia. It was the largest hydroelectric power station in Russia and the sixth- largest hydroelectric power station in the world before. Construction started in 1968 taking 10 years for it to be built and opening in 1978. The plant was designed by the Leningrad. After the fall of the Soviet Union the Station was privatized with RAO UES becoming the main shareholder. RusHydro operated the plant, controlling the output of 10 turbines which each had the capacity of 640MW.... [tags: khakassia, mechanical failure]

- ... Coal are utilized as fuel of boiler. The bituminous coal is utilized as boiler fuel has volatile matter from 8 to 33 % and ash content 5 to 16 %. In coal thermal power plant, the steam is engendered in high pressure in the steam boiler due to burning of fuel (pulverized coal) in boiler furnaces. This steam is further supper heated in a super heater. This supper heated steam then enter into turbine and rotates the turbine blades. The turbine is mechanically so coupled with alternator that its rotor will rotate with the rotation of turbine blades.... [tags: Coal, Boiler, Petroleum, Combined cycle]

- Autobiography at an Air-Station by Philip Larkin Progress is in the eye of the beholder. Throughout the years society has forced nature out of its life and has instead adopted a new mechanical and industrialized lifestyle. Technology may be deemed as progress by some, where it is thought of as a positive advancement for mankind. Yet technology can also be a hindrance for society, by imposing itself on society and emptying the meaning out of life. In “Autobiography at an Air-Station,” Philip Larkin conveys his distaste of how society has denounced nature.... [tags: Autobiography Air-Station Philip Larkin Essays]

- Ezra Pound's In a Station of the Metro Before this week, I had never read any poetry by Ezra Pound. I noticed immediately that many of the poems are very short. "In a Station of the Metro," for example, is two lines. In the essay "Imagism," the second rule of imagistes is said to be "to use absolutely no word that did not contribute to the presentation." I think this rule helps explain why some of Pound's poems are so short. Obeying the second rule of imagistes will be harder the longer the poem is.... [tags: Ezra Pound Station of the Metro Essays]
