OREANDA-NEWS. December 20, 2010. Power Machines OJSC manufactured and tested a new prototype 1200 MW high-speed turbine destined for Novovoronezhskaya NPP-2.

High-speed steam turbines and turbogenerators with the power of 1200 MW designed for NPP are the Power Machines’ innovative products intended for the new generation of nuclear power units with improved reliability and safety that are being developed in Russia within the “NPP-2006” project frames.

Design and production of K-1200-6.8/50 high-speed steam turbines involved implementation of new design solutions and technologies considering the experience in design and production of turbines for Kudankulam NPP, India, and that in operation of turbines at Tianwan NPP, China.
TZV-1200-2 turbogenerators that are designed and manufactured by Power Machines for NVNPP-2 and LNPP-2 present the progressive development for the series of completely water-cooled turbogenerators which are high-performance explosion- and fire-proof turbogenerators intended for nuclear power plants and having no equivalents in the world nuclear power plant engineering.

The procurement contracts for the main equipment set of the turbine hall to be installed at Novovoronezhskaya NPP-2 (NVNPP-2) and Leningradskaya NPP-2 (LNPP-2) being constructed were signed between the Power Machines company and Atomenergoprom OJSC in May 2008. The total price of the contracts amounts to over 40 bln rubles. Two power units with WWER-type reactors with the electric power of 1200 MW will be constructed at each nuclear power plant.

As per the contracts at the first stage the Power Machines company will provide for design, production and provision of the NVNPP-2 and LNPP-2 first power units with two sets of steam turbines, condensers and separate auxiliary equipment for turbine plant systems as well as two sets of turbogenerators with auxiliary systems’ equipment, excitation system and exciter. Power Machines being a complete turbine plant equipment supplier will procure heat exchanging and pumping equipment, tubing pipes and necessary fittings. Furthermore, specialists from the St. Petersburg’s power engineering company will supervise installation and commissioning operations at the NPP sites in respect of all the equipment supplied.

At the second stage the Power Machines company will procure the same equipment and services for the second power units of NVNPP-2 and LNPP-2.

NVNPP-2 and LNPP-2 are the first nuclear power plants to be built from scratch in Russia within the last 15 years.
