Czechia opens preliminary round for Dukovany-5 nuclear project

The Czech Industry Ministry has invited France’s EDF, Russia’s Rosatom, South Korea’s KHNP and Westinghouse of the United States to pre-qualify for a tender to build a new 1.2 GW unit at the Dukovany nuclear power plant. The country excluded China General Nuclear Power (CGNPC) due to security concerns. The authorities are expected to take a final decision on who will be allowed to bid by the end of 2021.

The Czech national power utility ČEZ already operates four VVER-440 reactors at the Dukovany nuclear power plant (2,040 MW) and two VVER-1000 reactors at the Temelín plant (2,160 MW). Replacing the older reactors with new units is viewed as crucial for the country’s energy security, as the four Dukovany reactors are expected to be shut down permanently between 2035 and 2037. Earlier in March 2021, the Czech State Office for Nuclear Safety awarded a permit to ČEZ for the development of two new 1.2 GW units at the Dukovany nuclear power plant. The company is currently planning to build only one reactor at Dukovany, and the permit for two units will allow ČEZ to review its plans. ČEZ is expected to set a preferred list of suppliers by 2022 and to sign a contract with one supplier by 2024. Construction should start in 2029, and commissioning is expected in 2036.
