To achieve a higher level of safe operation of the nuclear power plant, the construction of two fan towers and two super-emergency PG power supply facilities at the Dukovany Nuclear Power Plant was proposed.
The new cooling towers with fans are 17 metres high and, compared to the existing 125-metre-high cooling towers, are more resistant to seismic effects and extreme wind conditions, including tornadoes or prolonged high temperatures. The new cooling towers are primarily for cooling the plant's safety systems and the existing 8 cooling towers will be retained for cooling the turbine condensers. The terminal heat sink buildings will remove residual heat from equipment where long-term cooling failure cannot be allowed.
