Company successfully completed works for replacement of condenser of turbine К-1000-60/1500-2 powder unit No.4 Zaporizhia NPP. 
  
Company specialists performed full package of works for dismantling of 3 enclosures of condenser type К-33160 and assembly and installation of elements, assembly units and parts of condenser type К-38080 produced by PJSC “Turboatom”.

Works were performed in a quality manner, in accordance with design documentation and approved repair schedule of the power unit. Upon work completion, we conducted set of hydraulic tests of steam and cooling sections of enclosures of assembled condenser. Following the results of conducted quality inspection and tests, permit was obtained for launch of the equipment into operation. 
 
Replacement of condenser of turbine К-1000-60/1500-2, capacity 1000 MW, will provide:
  • exclusion of materials which contain cooper from equipment of 2nd circuit of turbine plant;
  • enhancement of leak-proof parameters of piping systems of condensers and reliability improvement of operation and operability;
  • obtaining enhanced vacuum (decrease steam pressure) in condensers without changing layout of turbine unit and building structures of turbine hall at existing seasonal fluctuations of cooling water temperatures;
  • obtaining  increase of electric power capacity of turbine plant on generator terminals;
  • reliable operation of the power unit during extended operation life.
