Czechia has eliminated Russia’s Rosatom from a tender to build a new 1.2 GW unit at the Dukovany nuclear power plant in a context of degraded diplomatic relations with Russia. In March 2021, Czechia had invited EDF, KHNP, Rosatom, and Westinghouse to pre-qualify for the tender. Czechia has previously excluded China General Nuclear Power (CGNPC) for security concerns. The Czech national power utility 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.
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). 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. 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.
