Hungary's Paks nuclear power plant, the country's only nuclear facility, has been forced to temporarily shut down a reactor block for the first time due to the exceptionally low water levels in the Danube River. The river’s decreased flow hindered the plant’s ability to cool the reactor safely, triggering the automatic shutdown. Water levels have fallen to critical points due to prolonged drought and high temperatures across Europe. Plant operators emphasize there is no safety risk, and the shutdown is a precautionary measure. The unusually low Danube poses challenges for inland river transport as well, disrupting shipping and supply chains. Authorities are monitoring the situation closely, and the reactor will restart when the river level recovers to a safe operating point. This event highlights the vulnerability of nuclear power generation to climate change impacts.
