The design and production of turbine units for nuclear power plants at Power Machines is concentrated at Leningradsky Metallichesky Zavod (LMZ) (Leningrad Metal Plant), which has extensive experience in the successful development, research and production of high-capacity steam turbines.
Power Machines produces high-speed steam turbines for NPPs with a capacity of 200 MW to 1200 MW. The high reliability and cost-effectiveness of the turbines has been proven by more than twenty-five years’ worth of operation at nuclear-power facilities.
Turbogenerators with a capacity of 100 to 1200 MW
Power Machines’ turbogenerators are manufactured at the Electrosila factory. The main features of these turbogenerators are high cost-effectiveness, control response, reliability, simplicity and ease-of-use in various climatic conditions.
Power Machines has developed highly-efficient explosion-proof completely water-cooled 1200 MW generators for high-capacity nuclear power plants. This equipment, boasting a high level of protection, has no comparables in the global nuclear-power industry.
Heat-exchanging and auxiliary equipment
In addition to its basic equipment, Power Machines also produces and supplies its own heat-exchanging and various auxiliary turbine-unit equipment, such as condensers, heaters, oil coolers, ejectors, valves, etc.
The condenser is one of the key elements in any nuclear power plant. The thermal performance of the power unit as a whole has been enhanced thanks to the use of an original tube system in the condensers produced by Power Machines. Power Machines has commenced the production of condensers with titanium heat-exchanging tubes. The use of titanium increases the reliability and service life of condensers regardless of cooling-water quality, while also reducing operating and repair costs. What’s more, the use of heat-exchanging tubes made of titanium and stainless steel instead of copper alloy tubes enhances the reliability of all NPP second circuit equipment.
The condenser is delivered to the NPP construction site as separately-assembled high-quality modules, which reduces the time of its installation at the plant.
Electrical automation systems
Power Machines supplies generating equipment complete with control and automation systems. The company offers the automation of the turbine building, including power unit and auxiliary equipment control systems, protection systems (both hydromechanical and electrical) and vibration control systems
The production of steam-drive turbine equipment is concentrated at Kaluga Turbine Works. 62 steam-drive turbines for the feedwater pumps of nuclear units have been supplied to NPPs in Russia, Ukraine, Bulgaria and India.
