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.
