PRAGUE, April 9, 2026
The Czech Republic announced plans to extend the operational lifespan of its oldest nuclear power plant, Dukovany, to up to 80 years, potentially keeping the Soviet-era facility running until 2065-2067.
Aging Infrastructure and Long-Term Plans
The Dukovany nuclear power plant, located in the Vysočina Region, consists of four reactor blocks of the Soviet WWER-440/213 type, which were connected to the grid between 1985 and 1987. Originally designed for a 30-40 year lifespan, the plant has already undergone multiple upgrades to ensure its continued operation. The latest proposal would push its operational timeline to an unprecedented 80 years, a move that has drawn both support and criticism.
The Czech government has framed the extension as a necessary step to ensure energy security and reduce reliance on fossil fuels. The country has long depended on nuclear power for a significant portion of its electricity, with Dukovany alone accounting for roughly 20% of domestic production. Officials argue that extending the plant’s life will provide stability as the nation transitions to newer energy sources.
Environmental and International Concerns
Environmental groups, particularly those in neighboring Austria, have strongly opposed the plan, labeling the Dukovany plant as outdated and dangerous. Austria, which has long been critical of nuclear energy, has raised alarms about the safety risks associated with aging reactors. The plant’s proximity to the Austrian border has further heightened tensions, with Austrian activists calling for stricter international oversight.
