Extreme drought across Europe has dropped water levels in the Danube River, exposing a WWII-era German vessel in Serbia. This environmental crisis is simultaneously forcing the first-ever shutdown of the Paks nuclear power plant in Hungary.
The Nazi wreck near Prahovo and Serbia's £4.3 milloin cleanup bill
Near Prahovo, Serbia, the receding waters of the Danube have revealed a German warship from the Second World War. According to the report, the vessel was likely scuttled by the German navy during their retreat from the Soviet Army in the closing stages of the war. This discovery is not an isolated incident, as the ship is one of approximately 200 wrecks currently resting on the riverbed of Europe's second-largest waterway.
These submerged remnants, which include various barges and cargo ships,create a persistent danger for river navigation. As the report says, the Serbian government spends roughly £4.3 million every year to clear these hazards from the shipping lanes. The current drought has essentially turned a hidden navigational risk into a visible historical marker, highlighting the sheer volume of wartime debris still lingering in the region.
Why the Paks plant's 40% energy share is at risk
The water shortage has moved beyond historical curiosity to a matter of national security in Hungary. The Paks nuclear power plant,a Soviet-era facility that provides roughly 40% of Hungary's total electricity, is scheduled to shut down next week. The facility relies on the Danube for its essential cooling water, but the river's levels have dropped so low that the plant's suction nozzles can no longer function effectively.
Prime Minister Péter Magyar has warned that this shutdown comes at a perilous time. With temperatures already exceeding 35°C (95°F) and forecasts suggesting further increases, the loss of the Paks plant's output could push the Hungarian energy grid to critical levels. The inability to cool the reactors is an unavoidable technical failure caused by the lack of available river water.
Romania's reactor shutdowns and the European heatwave
The crisis in Hungary is part of a cascading failure of energy infrastructure across the continent.. In Romania, record-high temperatures have already forced the shutdown of one nuclear reactor , with official plans currently in place to close a second. These events echo a broader pattern of extreme weather where record heatwaves are directly compromising the stability of the European power grid.
Local authorities across the affected regions have been forced to implement emergency measures to mitigate fire risks and reduce the strain on water and energy systems. This trend suggests that the cooling requirements for nuclear energy—often touted as a stable alternative to fossil fuels—are dangerously dependent on stable river levels that no longer exist during European summers.
The fate of the 200 river wrecks and the Paks restart timeline
While the immediate danger to Hungary's power grid is clear, several critical details remain unvreified. It is currently unknown when the Paks nuclear power plant can safely restart, as that depends entirely on the Danube's water levels recovering—a prospect that seems unlikely given the ongoing heatwave. Furthermore, the report does not specify if the newly revealed Nazi ship near Prahovo will be salvaged or if it will be left to the elements until the river rises again.
There is also a lack of clarity regarding how Hungary intends to fill the 40% energy gap left by the Paks shutdown. Whether the government will rely on increased imports from neighbors or implement rolling blackouts remains an open queestion that Prime Minister Péter Magyar has yet to fully address.
