The JSC Metallichesky Zavod delivered to the sea port of St. Petersburg  the 1000 Mw steam turbine, manufactured for the atomic power plant "Busher". The cargo consisting of 274 pieces and of the total weight of 2500 tons will be shipped to Iran by the end of July.

The contract for delivery of the turbo unit  was signed by the CJSC "Atomstroiexport" and the JSC "Leningradsky Metallichesky Zavod". It took one and a half year to design the unit and about two years to manufacture it.

The experts of the plant took into account the specific conditions at Busher – extremely hot climate in combination with high humidity of the air as well as high concentration of salt in it caused by proximity of the ocean.

The specialists of the LMZ managed to develop a principally new 1000 Mw high-speed turbine, which while complying with the customer’s specifications (weight – 1700 tons, length – 39,5 meters) was 1,3 times lighter than similar slow-speed turbines. The new turbine consists of three low pressure rotors and one high pressure rotor. The turbine was tested on the test bench of the LMZ in the presence of the Iranian customers.

Two more enterprises participate in production of the equipment for the atomic power plant "Busher", which belong to the Power Machines Group. One of them is the Turbine Blades Plant, which manufactured all runner blades and guide blades, inclusive of unique titanium 1200 mm blades for the last stage of low pressure cylinders, and the other the JSC "Electrosila", which manufactured the 1000 Mw turbo-generator.

Additional information

The Power Machines Group comprises the following joint-stock companies: Leningradsky Metallichesky Zavod, Electrosila, Turbine Blades Plant, Kaluga Turbine Works and Energomachexport – Power Machines.

The atomic power plant "Busher" is not the only project of this kind for the enterprises which make up the Power Machines Group. At present they are engaged in supply of equipment to the atomic power plant "Tian-Van" in China and "Kudankulam" in India.

The 1000 Mw turbine for the APP "Tian-Van", which was completed in August 2001, became the first turbine of such a capacity, manufactured by the Leningradsky Metallichesky Zavod for export. Currently a similar turbine is being manufactured; negotiation for supply of equipment for the third and the fourth blocks of the APP "Tian-Van" are under way.

The other Power Machines Group enterprises take part in construction of equipment for the "Tian-Van" and the "Busher" and the "Kudankulam" atomic power plants, namely: Electrosila and Turbine Blades Plant. To be more exact the JSC Electrosila has already manufacture the 1000 Mw turbo-generators for the APP "Tian-Van" and "Busher" (and is about to start similar work for the ASP "Kudankulam"); the Turbine Blades Plant manufactures all runner and guide blades.

The 1000 Mw turbines are one of the most powerful steam turbines utilised at present at atomic power plants. All together 20 turbines of such class are used to generate energy in the world, three of them were made by the JSC "Leningradsky Metallichesky Zavod" and installed at the Rovenskaya, the Khmelnitskaya and the Southern-Ukrainian atomic power plants. Three more, manufactured by the LMZ, are being currently installed at the Kalininskaya as well as the Rovenskaya and Khmelnitskaya atomic power plants.
