OREANDA-NEWS. September 22, 2009. The first 5 sections of the metal frame have been set up and installed for the wall panels of the Sayano-Shushenskaya HPP turbine room.  For the purposes of creating the thermal contour, restoration of the canopy of the turbine room needs to be completed before the cold weather sets in.  Work to install the structures is proceeding round-the-clock, the intention being to complete it by 11 November 2009.

It has been decided to restore the turbine room canopy destroyed by the accident at the hydro-electric power station according to the initial design, using the same technology and materials.  For precisely this reason, the order to manufacture the metal casing for the turbine room of the HPP was placed with the firm ViSta – the leading enterprise producing space frames of the MArchI type, the production facility being located in the town of Semyonov, Nizhniy Novgorod Region.  More than 30 years ago, this enterprise produced the structures for construction of the Sayano-Shushenskaya HPP and later those for the Bureyskaya HPP.

Let us recall that the first two of nine vehicles carrying parts of structures for assembly in restoring the turbine room arrived at the Sayano-Shushenskaya HPP on 11 September.  In accordance with the set time schedule, the next batch of parts has been delivered to the power station and another vehicle is en route.

Currently, more than 2000 people are involved in the accident and restoration work at the Sayano-Shushenskaya HPP, plus 46 pieces of equipment.

The accident at the Sayano-Shushenskaya HPP occurred on 17 August, 2009.  At the time of the accident, 9 of the Sayano-Shushenskaya HPP turbines were in operation (hydro-turbine No. 6 was in reserve).  The total active capacity of the turbines amounted to 4400 MW.  As a result of the damage to hydro-unit No. 2, the reason for which is being determined, water was ejected from the turbine crater.  Search and rescue work at the power station has now been completed and restoration work launched.  About 40 billion roubles will be needed to restore the power station.
