Ukrainian NPPs equipment modernization program
06 September 2019
President of NNEGC “Energoatom” Yuriy Nedashkovsky and General Director of JSC “Turboatom” Viktor Subotin signed Program for modernization of the equipment of 15 Units of Ukrainian NPPs for 5-year period up to 2024.
In addition, an agreement was signed between SS “Atomcomplect” NNEGC “Energoatom” and “Turboatom” for manufacture and supply “block-module” type condenser to replace K-1000-60 / 1500-2 turbine condenser at Unit 5 Zaporizhzhya NPP. It will provide increased reliability of operation of unit and increase its capacity by 25-60 MW.
According to tender procedures, contract amounted to 485 million hryivn. Delivery time of condenser is May-July 2020. Similar condensers, manufactured by “Turboatom”, have already been successfully operated at units No 2, No 3 and No 4 of Zaporizhzhya NPP, units No 1 and No 2 of the South-Ukraine NPP, and at unit No 3 of South-Ukraine NPP installation of the condenser is in progress.
NPP equipment modernization program includes two main sections, first of which involves the replacement of 8 turbine condensers for NPPs. Including, within scope of import substitution, replacement of 4 condensers of Russian manufacture is planned. Total capacity increase of nuclear power units after replacement of condensers will be about 400 MW.
The second section of the Program provides for modernization of flow parts of cylinders of 220 MW and 1000 MW turbines. Modernization includes replacement of moving blades on existing rotors and diaphragms that will increase the capacity of turbine and its efficiency. In framework of the Program it is planned to modernize high-pressure cylinders of Zaporizhzhya NPP turbines starting in 2020. It is expected that modernization of turbines will increase capacity and efficiency of existing Ukrainian NPPs by 10% that will increase capacity by 70-100 MW on each unit and achieve capacity of unit 1100 MW.
