A supplier for a new unit at Czech utility ČEZ’s Dukovany nuclear power station should be chosen by the end of 2022, prime minister Andrej Babiš said, according to local press reports.In July the Czech government approved a preliminary plan for a ČEZ subsidiary to build a new unit at Dukovany. Czech energy policy calls for one new unit at Dukovany and possibly three more either at Dukovany or the country’s other nuclear station, Temelín.The Czech government, which owns 70% of ČEZ, has been in discussions with the utility about how to expand nuclear power and to replace aging commercial reactors that are scheduled to be permanently shut down in the decades ahead.
