Water-water energetic reactor (WWER / VVER) are installed at the power units of Zaporizhzhia NPP. Power units with a reactor of WWER type have two circuits that do not communicate with each other.
- Reactor core
- Control rod drives
- Main circulation pump
- Steam generator
- Transformer. Electric power supply to consumers
- Cooling tower
- Cooling pond
Main solutions related to the configuration
Each of Zaporizhzhia NPP power units is equipped with the following basic equipment:
- Reactor compartment
- Turbine compartment
- Diesel generator
- Unit-shared pump station
- Auxiliary buildings 1 and 2
- Solid radwastes storage
- Joint auxiliary building
- Laboratory buildings 1 and 2
- Administrative building, check-point 1
- Check-point 2
- Dry spent fuel storage facility site
- Spray ponds
- Full-scope simulator facility
- 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.
