Published On 2 Aug 2026
BUDAPEST, Hungary – Hungary has announced it will shut down its only nuclear power plant after record-low levels on the Danube River reduced the water available for cooling its reactors.
Prime Minister Peter Magyar said the Paks Nuclear Power Plant in central Hungary would be powered down on Sunday, the first full shutdown in its 44-year history. The plant supplies nearly half of Hungary’s electricity.
