Specialists of OJSC Turboatom, the only Ukrainian producer of turbine equipment for hydro, thermal, and nuclear power plants, developed a new steam turbine K-1250-6,8/25 of rated power 1.250 MW. It is designed for new generation of NPP units with WWER-TOI (water-water energy reactor, typical, optimized, informatized), the Information-Analytical Bulletin of the Cabinet of Ministers of Ukraine informs.
Experts say these reactors feature high level of NPP autonomy in emergency mode and low volume of solid radioactive waste and emissions.
Efficiency of the turbine plant is over 37.5%; it is highly reliable, its availability ratio reaches 0.99%. Design of the turbine utilizes high-strength welded-forged rotors of high and low pressure, which are not subject to stress corrosion.
The advantages of new turbine include high maintainability and longer turnaround time of service (over 6 years).
Also, the new generation turbines are designed for gradual replacement and upgrade of 24 NPPs in 7 countries partners of the Kharkov Company. That will ensure a long-term portfolio of international orders for Turboatom, which is ranked 4th on the global market of NPP turbines.
Experts also emphasize the exports changes of the company in 2013. Export of turbines was down by 10%, and accounted for 50% of "Turboatom" production. This is not due to reduced production, but because of gradual upgrade in energy system of Ukraine. After all, Turboatom plays a central role in this process. Thus, 40% of thermal, 85% of nuclear, and 95% of hydro power plants in Ukraine (total capacity 60 million kW) are equipped with Turboatom products.
