  2. Reactor core
  3. Control rod drives
  4. Main circulation pump
  5. Steam generator
  6. Turbine
  1. Condenser
  2. Generator
  3. Transformer. Electric power supply to consumers
  4. Cooling tower
  5. Cooling pond
  6. Pump


Main solutions related to the configuration

Each of Zaporizhzhia NPP power units is equipped with the following basic equipment:

  • Water-water energetic reactor of WWER-1000 type, manufactured by production association "Izhora factory", St. Petersburg
  • Turbine facility of К-1000-60/1500-2 type, manufactured by production association for nuclear turbine building "Kharkiv turbine-building factory", Kharkiv
  • Generator of ТВВ-1000-4 type, manufactured by production association "Elektrosila", St. Petersburg

  1. Reactor compartment
  2. Turbine compartment
  3. Diesel generator
  4. Unit-shared pump station
  5. Auxiliary buildings 1 and 2
  6. Solid radwastes storage
  7. Joint auxiliary building
  8. Laboratory buildings 1 and 2
  1. Administrative building, check-point 1
  2. Check-point 2
  3. Dry spent fuel storage facility site
  4. Spray ponds
  5. Canteen
  6. Full-scope simulator facility
  7. Training center


Unified one-piece construction is located in separated main building of the NPP; it includes reactor compartment, turbine hall, deaerator stack and electrical equipment rooms.

NPP main buildings are oriented to the cooling pond that is source of NPP circulative water supply. Unit-shared pump stations, technical water supply pipe-lines and automobile roads are located in between the power unit main buildings.

Zaporizhzhia NPP connection to united electric power grid of Ukraine is performed via three electric-power transmission lines with voltage 750 kV and one electric-power transmission line with voltage 330 kV of alternating current.
