Romania Shuts Nuclear Plant as Danube Water Levels Reach Crisis Point

Romania, Europe — Cernavodă nuclear plant shuts down as extreme heat and falling Danube levels threaten energy security

Romania has shut down its only nuclear power station after exceptionally low Danube River levels reduced the water available to cool its reactors, adding fresh pressure to Europe’s electricity systems during a summer of prolonged heat, drought and wildfires.

The Cernavodă nuclear power plant, which normally supplies about one fifth of Romania’s electricity through two reactors, is not expected to return fully to operation within the next 10 days, according to plant director Romeo Urjan already.

The second 706-megawatt reactor was disconnected from Romania’s electricity grid shortly before midday on Thursday, after the first reactor had already been taken offline in July because of deteriorating river conditions and limited cooling-water availability.

Cernavodă depends on the Danube for cooling, making the plant particularly vulnerable when the river falls to unusually low levels. Authorities recently attempted to improve water flow by sinking barges loaded with rocks near the plant today.

The measure has not prevented the shutdown, highlighting how extreme weather can affect infrastructure designed around relatively stable environmental conditions. Cernavodă had previously experienced only one complete shutdown, in 2003, according to the information released about the plant.

Romania must now compensate for the lost nuclear generation as electricity demand remains elevated during hot weather. Solar and wind power can cover part of the shortfall during daylight, but evenings will require conventional generation and electricity imports nationally.

The country has significant hydropower resources as well, but low water levels are reducing their contribution at precisely the moment nuclear output has disappeared. That combination leaves Romania facing a tighter electricity balance during an already difficult summer overall.

Neighbouring Hungary is facing a similar threat at the Paks nuclear power station, which contains four Soviet-era reactors and also relies on the Danube for cooling. Officials have warned that continued river decline could eventually force wider shutdowns today.

Hungarian authorities have so far avoided closing Paks entirely, although plant officials previously said the Danube had fallen so low that suction nozzles used to draw cooling water could struggle to reach the river.

The Danube is Europe’s second-longest river and a critical source of water, transport, agriculture and energy across several countries. Its exceptionally low levels are therefore creating consequences far beyond the immediate problem of cooling nuclear reactors.

In some locations, water levels have reached their lowest points in roughly three decades. The decline has also exposed previously submerged objects, including wartime wreckage, while restricting commercial navigation and increasing pressure on communities dependent upon reliable river flows.

The crisis comes as Europe experiences another period of severe summer heat. Climate monitoring agencies have repeatedly identified Europe as the world’s fastest-warming continent, with temperatures increasing at roughly twice the global average in recent decades.

Hotter conditions are intensifying pressure on water supplies and increasing the likelihood of drought, wildfires and heatwaves. Rivers become especially important during such periods because their water is needed simultaneously for ecosystems, agriculture, transport and industrial cooling nationally.

Germany’s Rhine, another major European waterway, has also experienced low water levels, limiting shipping and raising costs for businesses that depend on the river to move raw materials and finished products across the continent and regional supply chains significantly.

Europe’s agricultural sector is also absorbing significant losses from the combination of drought, extreme heat, hail and fires. Italy’s agricultural trade association Coldiretti has estimated climate-related damage could exceed three billion euros this year.

France is facing similar economic concerns. Environment Minister Monique Barbut has warned that recent heatwaves could generate between €10bn and €15bn in direct and indirect costs, according to data from the country’s national statistics agency.

Economists and financial institutions have also warned that persistent extreme weather could weaken Europe’s already modest growth outlook. Dutch bank Triodos said severe heat and its consequences could eliminate much of the European Union’s projected economic expansion.

The European Commission had previously forecast growth of 1.1 percent for the European Union, while the International Monetary Fund expected the euro area to expand by around 0.9 percent, leaving little room for prolonged weather-related disruption.

Southern Europe has simultaneously faced a dangerous wildfire season. In northern Greece, more than 200 people, many of them tourists, were evacuated from the popular resorts of Siviri and Fourka as firefighters battled a fast-moving blaze.

France has also remained under severe heat pressure, with around 80 departments placed on heatwave alert as temperatures were forecast to exceed 40 degrees Celsius in some areas. The country has suffered extensive wildfires during recent weeks.

Spain, which is still recovering from deadly fires, recorded temperatures approaching 37 degrees Celsius in central areas on Thursday. The persistent heat has kept pressure on emergency services, agriculture, water supplies and communities already affected by drought.

The United Kingdom also experienced its hottest day of the year so far on Thursday. The Met Office reported a provisional temperature of 38.1 degrees Celsius at Kew Gardens in London, while multiple fires affected areas across the West Midlands.

Several people were reported injured in the West Midlands fires, while four homes were destroyed. Rain is expected in more parts of Britain over the weekend, but climate experts say showers alone will not end widespread drought nationwide.

Romania’s nuclear shutdown demonstrates the interconnected nature of Europe’s climate and energy challenges. A river falling to historically low levels can simultaneously disrupt electricity generation, hydropower, shipping, agriculture and ecosystems across national borders. nationwide today

The immediate challenge for Romania is maintaining a stable electricity supply while the reactors remain offline. Imports and fossil-fuel generation can provide backup, but both options carry economic or environmental costs, especially during periods of high regional demand.

The longer-term question is whether Europe’s critical infrastructure is prepared for increasingly frequent extremes. Nuclear plants, power stations, waterways and agricultural systems were designed around historical climate conditions that may no longer reliably represent future risks.

For Cernavodă, operations will depend on whether Danube conditions improve enough to provide safe and sufficient cooling water. Until then, Romania faces another reminder that Europe’s worsening heat and water stress can quickly become an energy security problem.
