The document summarizes a catastrophic accident that occurred at the Sayano-Shushenskaya Hydroelectric Power Station in Russia in August 2009. It provides background on the power station and details regarding the accident, which involved the sudden ejection of Turbine 2 from its mounting due to a water hammer event. This caused severe damage throughout the powerhouse and flooding, resulting in 76 deaths. The plant supplied 10% of energy to Siberia and its long-term repairs will have major economic impacts. Investigations into the root cause are still preliminary but suggest a large debris item may have blocked and suddenly closed the turbine gates.

3. Objetive
This presentation aims to disseminate some
technical and general aspects of the accident. A
long and detailed work must be done in order to
provide understanding about what happened, in
order to help all Owners to prevent such
accidents.
Note
This is a preliminary analysis made based only on pictures
and films, done no longer than one week after the
accident. Only hypotheses are formulated.
4. 1- Main Characteristics
Number of Units: 10
Turbine Type: Francis (16 blades)
Rated Power: 650 MW each
Rated Discharge per Unit: 358,5 m³/s
Nominal Speed: 142,86 rpm
Net Head: 194 m
Operation Date: 1978
Runner Weight: 156 ton
Runner Diameter: 6,77 m
5. 2 - Main Characteristics
One of the world's largest hydro-electric plants, its dam is
245 m (800 ft) high and stretches 1 km (0.6 miles)
across the Yenisei river.
Opened in 1978, the station provides a quarter of
RusHydro output and is a major power supplier to at
least two smelters owned by United Company RUSAL,
the world's largest aluminium producer.
The hydroelectric power station is located on the Yenisei
River, near Sayanogorsk in Khakassia, Russia. Before
the accident, it was the largest power plant in Russia and
the sixth-largest hydroelectric plant in the world.
13. The accident
At 08:13 local time (00:13 GMT) on 17 August 2009, the station suffered a
catastrophic "pressure surge" in turbine known as a water hammer. The
sudden water pressure surge resulted in the ejection of turbine 2 with all
equipment, a total weight some 900 tons, from its seat.
Turbines 7 and 9 also suffered from severe damage, while the turbine room
roof fell on and damaged turbines 3, 4 and 5. Turbine 6, which was in
scheduled repair at the time of accident, received only minor damage as it
was the only one of the station's 10 turbines that did not receive electrical
damage due to shorting of transformers, and it will be restarted as soon as
possible.
Water immediately flooded the engine and turbine rooms and caused a
transformer explosion.
On 23 August 2009, authorities said 69 people were found dead while 6 people
are still listed as missing. Efforts to pump flood water from the engine room
and complete a search for the missing workmen are expected to take 3 to 8
days.
http://en.wikipedia.org/wiki/2009_Sayano%E2%80%93Shushenskaya_hydroelectric_power_station_accident
36. Consequences
76 people dead.
Question: By this number, maybe
there was approx. 100 people
in the Powerhouse. Normally,
even during maintenance
works, there aren't so many
people. Why was there so
many people?
37. Consequences
It will cost at least $310 million.
A long time to repair the damages.
The production of more than
500,000 tons of aluminum will be
lost.
Oil slick is travelling down the
river.
38. Consequences
• It is not clear how many people
were potentially affected by the
accident.
• The plant satisfied 10% of
Siberia’s energy needs.
• Aluminum smelters consumed
over 70% of the energy
generated by the power plant.
39. Our main hypotheses about the sequence of the disaster:
(Attention: Preliminary hypotheses based only on the pictures)
Sudden closing of the Unit 2 wicket gates.
Heavy waterhammer in the spiral case and penstock, causing their
collapse.
Upward force, resulted from the waterhammer, destroying the civil
structure over the spiral case and penstock.
Pressure of the upstream water causing elevation of structures and
peaces.
Heavy reverse waterhammer (draft tube) causing elevation of the
turbine cover, shaft, etc.
Rapid flooding of the Powerhouse.
Units 7 and 9, without closing, in runaway speed with the generators
inside the flood water.
1 - Causes
40. Our main hypotheses about the cause of the sudden
closing:
A large piece entered in the turbine runner and stuck in it (could not
pass the exit of the blades, which is of smaller dimensions).
This piece turned with the runner and hit all the wicket gates,
causing their sudden closing, at a fraction of a second.
This piece could be: a log (passed by an opening in the trashrack),
stay vane or wicket gate broke.
Or (less probably):
Rupture of the governor oil pipe in the closing side of the distributor
servomotors (in this case, the orifice that controls the oil flow should
be in the pipe and not in the body of the servomotors).
Rupture in sequence of the wicket gates links; closing by hydraulic
tendency.
2 - Causes
55. Continuing the seeking of victims.
and
Finishing the cleaning of the debris.
Completing the drainage of the water.
Constructing a temporary roof (one week) and then a better one
(two months or less) to protect against the winter (this will prevent
new photos…).
Recover the columns and beams supporting the rails of the
Powerhouse Crane, to allow its use.
Some Next Steps
56. News – August 21
NOVOSIBIRSK, August 21 (Itar-Tass) - The water level in the inundated
turbine room of Sayano-Shushenskaya hydropower plant where the water
pumping out was started on Thursday, decreased by 2 meters by Friday
morning
A total of more than 30 thousand cubic meters of water have been pumped
out. It is necessary to pump out a total of 250 thousand cubic meters of
water.
Minister Sergei Shoigu earlier set the task to install additional pumps and
thereby increase the volume of pumped out water to 4 thousand cubic
meters per hour. “By increasing the capacity we will fulfill this task (water
pumping out) in 32 hours,” the minister said.
Thirteen pumps have been put into operation in the water pumping efforts at
the plant. The debris clearing operation continues. According to latest
reports, 4,650 cubic meters of reinforced concrete structures have been
moved out from the hydroelectric station.
At present, about 2 thousand people and 116 machinery units are engaged
in the Sayano-Shusehnskaya HPP catastrophe liquidation efforts.
