Romania’s nuclear reactor worries persist on Danube water level forecast

Romania's nuclear power plant on the Danube faces concerns over low water levels, according to the country's water management agency, which predicts the situation will worsen in the coming days. Despite emergency measures taken to redirect cooling water to the single operational reactor, the agency forecasts that the Danube's water level near the Cernavoda facility will remain at an all-time low for the next seven days, with further decline expected until August 16.

The low levels have already forced the shutdown of one of Romania's two reactors, which supply 20% of the country's power needs. To ensure the other reactor continues to operate, authorities have implemented various measures, including digging a dike, dredging the river bed, and sinking barge-filled rock dams to redirect water flow.

These actions have managed to increase water levels around the reactor by 4cm, potentially extending its operational lifespan by nine days. However, forecasted rains upstream are unlikely to alleviate the issue, as the Danube's entry point into Romania will continue to experience record-low levels. Acknowledging the severity of the situation, Romania's government has allocated additional funds for dredging efforts to deepen riverbeds in areas surrounding the nuclear plant.

In an effort to mitigate the impact of low water levels on power generation, Romania has declared a state of energy emergency for the entire month of August and urged companies and households to voluntarily reduce electricity consumption during peak evening hours. The country relies on a diverse mix of energy sources, including gas, coal, hydro, nuclear, and renewables, but faces a pressing need for significant investment to modernize aging infrastructure and integrate more renewable energy solutions, including advanced battery storage and grid interconnections.
