About the project
The construction of new units at Dukovany is the largest investment in the history of the Czech Republic
Nuclear energy plays an important role in the Czech energy mix, and its importance will continue to grow. The construction of two new units in the Dukovany site is expected to begin in 2029 and will create thousands of jobs directly, tens of thousands of jobs indirectly, and generate significant business for Czech contractors. Trial operation is scheduled for 2036–2037.

Meet the new Dukovany nuclear power plant
The cooling towers with expected height of up to 186 meters combine wet and dry cooling technology to minimize water consumption while maintaining high efficiency in electricity production.
The circulating water pump house. The circulating water system removes heat from steam turbine condenser to the cooling towers.
The turbine generator building with steam turbine and generator. It houses all the main equipment of the non-nuclear part of the power plant (including e.g. steam turbine condensers connected to cooling towers).
The water treatment building serves to produce demineralized water for the primary and secondary circuits and closed cooling water circuits and technological processes in the nuclear and non-nuclear parts of the power plant.
The spent fuel interim storage for dry storage of spent fuel in casks – this facility is not part of the power plant construction and will be subject to future licensing and permitting procedures (including environmental impact assessment).
The reactor building consists of double containment for maximum safety – to prevent the release of radioactive substances in the event of an accident and to protect the reactor from external hazards (including the impact of a large commercial aircraft). The primary containment is made of 1.2 meters of prestressed reinforced concrete with an internal steel lining to ensure maximum leak-tightness. The secondary containment is made of 1.5 meters of reinforced concrete.
The compound building shared between both power plant units is used for radioactive waste management. It also houses the entrance to the controlled area of both units and hot workshops used for maintenance of the equipment of the nuclear part of the power plant.
In addition to safety systems, safety features and fuel storage (dry storage for fresh fuel and spent fuel pool for storing spent fuel), the auxiliary building also houses the main control room, from which the entire power plant unit is controlled. The advanced redundant safety systems and safety features are provided.
The emergency diesel generator buildings house diesel generators which provide emergency power supply to safety systems and safety features in the event of loss of main and backup power supply.
Mechanical draft cooling towers ensures heat removal from systems of the nuclear part of the power plant (including safety systems and safety features).
The main transformers for transferring the generated electrical power from the generator to the Slavětice switchyard. The unit auxiliary transformers for ensuring the power plant's house load during its power operation. The stand-by auxiliary transformers for ensuring backup power supply from the electric power transmission system.
Contractor
The contractor for the two new units at the Dukovany site is the South Korean company Korea Hydro and Nuclear Power (KHNP).
