Hungary Shuts Down Paks Nuclear Plant Due to Danube Drought

Hungary has shut down the Paks nuclear power plant after a severe heatwave left the Danube River with insufficient water for reactor cooling [1, 2].

This event marks a critical failure in the nation's energy infrastructure, as the facility provides a primary source of electricity for the country. The shutdown highlights the growing vulnerability of nuclear energy systems to extreme climate events and water scarcity.

The government of Prime Minister Peter Magyar said that the shutdown was expected for the weekend of Aug. 1-2 ^[3]. The decision follows a period of intense drought that resulted in record-low water levels in the Danube ^[4]. Because nuclear reactors rely on large volumes of water to regulate temperature, the lack of available cooling water made continued operation impossible.

This is the first time the plant has been shut down in 44 years ^[1]. The facility is Hungary's only nuclear power plant, meaning the loss of its output places significant pressure on the national power grid during a period of high energy demand caused by the heatwave.

Officials said the current period is a set of critical days for the nation's energy stability ^[5]. While some reports indicated the shutdown was imminent, others confirmed the heatwave had already forced the facility offline [1, 5]. The timing of the closure arrived days earlier than some initial predictions had suggested ^[3].

The Paks plant remains the cornerstone of Hungary's energy strategy. The current crisis underscores the interdependence between river health and industrial stability, a link that is becoming increasingly fragile as heatwaves intensify across Europe.
