Following the conclusions and recommendations of the National Action Plan for the Development of Nuclear Energy of the Czech Republic, CEZ, a. s. established a subsidiary - Elektrarna Dukovany II, a. s. in 2015, which implements the project of New Nuclear Power Plant in Dukovany Site. The company Elektrarna Dukovany II, a. s. is part of the CEZ Group and fully controlled by CEZ, a. s. (further corporate information, such as Board members, is available in the CEZ Group's notable entities overview (in Czech).
The only nuclear reactor technology considered for the New Nuclear Power Plant in Dukovany Site is Pressurized Water Reactor technology. This type of reactor can be supplied by a several world-renowned manufacturers nowadays:
- AP1000, Westinghouse Electric Company LLC (USA);
- APR1000, Korea Hydro&Nuclear Power (South Korea);
- EPR1200, Framatome, EDF Group (France) and Siemens (Germany).
The power limitation of Dukovany Site is based on the results of the analysis of technical and natural limits, where a smaller range of actions with considerably lower risks should be implemented for the placement of reactors with a power output up to 1200 MWe than in the placement of medium (1450 MWe) or large (1750 MWe) power units.
With the anticipated parallel operation of New Nuclear Power Plant in Dukovany Site with four constantly operated units of the Nuclear Power Plant Dukovany, only the unit with an output up to 1200 MWe can be operated so as not to exceed the total net electrical power in Dukovany Site of 3250 MWe. In the case of a medium (1450 MWe) or large (1750 MWe) unit, at least one unit of the existing power plant would have to be shut down prematurely. For medium power technology with two steam generators (1450 MWe), it is unrealistic to ensure the transportability of heavy and large components in accordance to the conditions of the transport infrastructure of the Czech Republic. Moreover, the parallel operation of two medium (1450 MWe) or large (1750 MWe) units is excluded due to power grid limits in Czech Republic.
