ČEZ applies for permission to build two new blocks at the Dukovany Nuclear Power Station

Czech utility company ČEZ filed for permission with the State Office for Nuclear Safety to build two new nuclear power blocks at Dukovany, concluding a five-year preparations period and being ready for the licensing process in accordance with the Atomic Energy Act.

“As with any environmental impact assessment, our goal in licensing is to maximise openness and transparency, which is why we have also published the entire Tender Safety Report so that the public can freely access the key document,” said Daniel Beneš, Chairman of the Board of Directors and Chief Executive Officer of ČEZ.

The report describes and assesses the site’s characteristics, examining the natural conditions, water supply and human activities near the power plant. Also described and evaluated are the project’s concept, quality issues and preliminary impact of operations on the population and environment and the future decommissioning of the power plant. In order to determine the subsoil’s condition, experts performed geological drilling at over 170 spots at the future construction site for a total length of more than 4 kilometres. Thirty deep wells were also drilled in order to monitor groundwater, with a depth of up to 150 metres and a total length of almost 2 kilometres.

“The fact that four nuclear power blocks are already operating at the Dukovany location has only partially assisted us,” continued Petr Závodský, CEO of EDU II, which is a subsidiary of the applicant for the authorisation. “Of course, the advantage was a large amount of input data available to us, and we could also draw from a number of reports, findings and stress test results. However, we also needed to do a comprehensive analysis of all the requirements of the Czech nuclear legislation and the standards of the International Atomic Energy Agency and many other institutions. For us, the defensibility of the project internationally is crucial.”

The subject of the application is the placement of two nuclear facilities, each with a single pressurised water reactor of electrical power up to 1,200 megawatts electric (MWe). The procedure makes it possible to consider the energy and climate objectives of the Czech Republic, which are currently being specified, and only then can the construction of one or two power blocks in the future be decided. The State Office for Nuclear Safety is empowered to interrupt the authorisation process at any time and request supplementary information.
