State-owned enterprise National Nuclear Generating Company Energoatom and JSC Turboatom (Kharkiv) signed the five year (2020-2024) program on modernizing equipment of Ukrainian nuclear power plants (NPPs) on Tuesday.

According to a press release of Energoatom, the program involves the replacement of eight turbine condensers of nuclear power reactors, including four Russian-made condensers. After replacing the condensers, the total increase in power of reactors will be about 400 MW.

The document also provides for the modernization of flowing parts of turbine cylinders with a capacity of 200 MW and 1000 MW, including five turbines with a capacity of 1000 MW as part of import substitution. Modernization includes the replacement of rotor blades on existing rotors and diaphragms, which will increase the turbine’s power and its efficiency.


It is also planned to upgrade the high-pressure cylinders of the turbines of the Zaporizhia NPP, starting in 2020. Modernization of turbines will increase the capacity and efficiency of existing reactors of Ukrainian NPPs by 10 percent, which will provide a power increase of 70-100 MW at each reactor.

In addition, on Tuesday in Enerhodar (Zaporizhia region), an agreement was signed between Atomkomplekt (a separate division of Energoatom) and Turboatom for the manufacture and supply of a block-modular condenser for replacing the condenser of the K K-1000-60/1500 turbine at reactor five of Zaporizhia NPP in April 2020.

The parties also discussed a long-term repair program for the replacement of used spare parts.

“Four years ago, we gave a new powerful start to our cooperation, which is not only servicing the turbine park, but also the replacement and modernization of equipment. This will allow us to increase and improve the efficiency of nuclear power plants, to increase the generation of electric energy, which is important in conditions a new market, when every additional kilowatt-hour produced gives additional income,” Energoatom President Yuriy Nedashkovsky said.


According to the CEO of Turboatom Victor Subbotin, the volume of modernization at Energoatom for five years will exceed Hr 6 billion, which is a significant contribution to the utilization of production capacities and personnel of the enterprise.
