Powerful waters
Boston.com has a portfolio of pictures taken following the August 17th accident at the Sayano-Shushenskaya hydroelectric plant and dam in south central Russia which killed at least 74 workers (one remains missing). The exact sequence of events is still under investigation, but preliminary indications are that the plant’s #2 turbine failed, blocking its water flow. Safety systems which should have closed the corresponding upstream intake gate also failed. The water, under tremendous pressure (head is about 800 feet), flooded into the plant’s generator hall, ripping the front and roof off 1/3 of the building and destroying 3 of the plant’s 10 turbines.
Above, before and after images.
Americans shouldn’t start feeling too superior until after they check out what happened at Niagara Falls in 1956.
