Czech Republic Extends Operational Life of Dukovany Nuclear Power Plant Prague, Czech Republic — April 9, 2026 The Czech Republic has decided to extend the operational lifespan of its Soviet-era Dukovany nuclear power plant, with the four reactor blocks now expected to produce electricity until at least 2065. The Czech government confirmed on Tuesday that the four reactor blocks at the Dukovany nuclear power plant, originally connected to the grid between 1985 and 1987, will continue operating for decades longer than initially planned. Current economic and safety analyses have demonstrated the feasibility of extending their service life, ensuring the plant remains a cornerstone of the country’s energy strategy.
The Dukovany facility, located near the Austrian-Czech border, houses reactors of the Soviet-designed WWER-440/213 model. These units have been a critical part of the Czech energy grid for nearly four decades, providing a stable supply of electricity. The decision to prolong their operation comes as the country also moves forward with plans to construct two new reactor blocks at the same site.
## Extended Lifespan and Safety Assessments Recent evaluations by Czech authorities and the state-owned energy company CEZ have concluded that the existing reactors can safely operate well into the 2060s. The findings align with broader efforts across Europe to reassess the role of nuclear power in achieving energy security and climate goals.
The extension marks a significant shift from earlier projections, which anticipated the reactors would be decommissioned sooner. Officials emphasized that the decision was based on rigorous technical and economic assessments, ensuring compliance with modern safety standards.
## Expansion Plans with South Korean Partner In addition to extending the life of the current reactors, the Czech Republic is advancing plans to expand the Dukovany site with two new reactor blocks. Last year, the South Korean energy company Korea Hydro & Nuclear Power (KHNP) was awarded the contract for the project, beating out competitors from other nations.
The new reactors are expected to complement the existing units, further solidifying the Czech Republic’s reliance on nuclear energy. The partnership with KHNP underscores the country’s commitment to modernizing its energy infrastructure while maintaining a diverse mix of power sources.
The expansion is part of a broader strategy to reduce dependence on fossil fuels and meet growing electricity demand. Officials have not yet announced a timeline for the completion of the new reactors, but the project is seen as a long-term investment in the nation’s energy future.
## Regional and Economic Implications The decision to extend Dukovany’s operational life has significant implications for the Czech Republic’s energy market and its neighbors. The plant supplies a substantial portion of the country’s electricity, and its continued operation ensures stability amid fluctuating energy prices and supply chain challenges.
Neighboring Austria, which has historically opposed nuclear energy, has raised concerns about the plant’s proximity to the border. However, Czech officials have reiterated their commitment to adhering to international safety protocols and maintaining transparency with neighboring countries.
Economically, the extension is expected to preserve jobs and support local communities near the Dukovany site. The plant has long been a major employer in the region, and its prolonged operation will likely sustain economic activity for decades to come.
As the Czech Republic moves forward with both the lifespan extension and the construction of new reactors, the Dukovany nuclear power plant remains a focal point of the nation’s energy policy. The dual approach reflects a balanced strategy of leveraging existing infrastructure while investing in next-generation technology.
