BUCHAREST, Romania – Record-low water levels on the Danube River are posing a significant threat to Romania’s Cernavoda nuclear plant, prompting operators to shut down one of its two reactors. The water shortage has raised concerns over cooling the remaining reactor, which is operating under reduced capacity.
According to the plant’s operator, Societatea de Administrare a Reactorului Nuclear (Nuclearelectrica), the Danube’s water levels have dropped to their lowest in history, with the current level at 0.3 meters (1.0 foot) above the plant’s minimum operational threshold. This has forced the shutdown of unit three, the second reactor to be taken offline in recent months. Unit one, however, remains operational but is now generating at 70% of its capacity.
Nuclear experts say the crisis is a result of a prolonged drought in the region and a low snowpack in the spring, which has severely impacted Danube’s water levels. The situation is further exacerbated by climate change, which is expected to lead to more frequent droughts in the region.
Efforts are underway to mitigate the crisis, with authorities and plant operators working together to dredge the river and divert water from nearby tributaries. Rock-filled barges are also being used to create artificial waterfalls that can help redirect the water towards the plant. However, forecasts indicate that water levels are likely to continue falling throughout the remainder of August, which has raised concerns that the remaining reactor could shut down soon.
The Cernavoda plant is Romania’s only nuclear power plant and provides about a third of the country’s electricity supply. The plant’s shutdowns and reduced capacity have already had significant impacts on the country’s energy market, driving up energy costs and forcing consumers to rely on imported energy sources.
Romanian energy minister, Virgil Popescu, has pledged to take all necessary measures to ensure the safe operation of the plant and to address the crisis. However, the impact of the water shortage on the country’s energy security remains a major concern. As the situation continues to unfold, it is clear that finding a solution to the Danube water crisis will be a significant challenge for Romania and its energy sector.
The ongoing issues at the Cernavoda nuclear plant highlight the vulnerability of the region’s energy infrastructure to climate-related risks and emphasize the need for more robust measures to mitigate the impacts of droughts and water shortages on the energy sector.
