Romania adopts new measures to boost Danube waters to cool Cernavoda nuclear plant

Romania has initiated the shutdown of the second reactor at the Cernavoda nuclear plant due to critically low water levels in the Danube River. To counteract this environmental challenge, the Romanian government is implementing measures to boost Danube waters to ensure the facility can maintain necessary cooling processes. This operational disruption is part of a broader regional trend where extreme heat and drought are impacting energy infrastructure across Europe, specifically affecting plants that rely on river water for thermal regulation. Coverage from Business Recorder and Taylorville Daily News emphasizes the specific actions taken at the Cernavoda plant. Meanwhile, Anadolu Ajansı and CGTN report that Bulgaria's Kozloduy nuclear plant has also been forced to curb its output because of the Danube drought.

Specifically, БНР Новини notes a reduction in the capacity of Unit 5 at the Kozloduy NPP, though the outlet clarifies that there is currently no crisis. Yahoo reports that this is a systemic issue across Europe, where heatwaves are forcing multiple nuclear plants offline as rivers run too low to support reactor cooling. This situation highlights a growing conflict between climate extremes and clean energy efforts. According to citybuzz, drought has also halted a nuclear plant in Hungary, suggesting that the reliance on river systems creates a vulnerability in the European energy grid. This instability is framed within a larger geopolitical context of energy security, as noted by Table.Briefings, which connects these extreme heat events to broader security concerns.

POLITICO Pro further underscores the severity of the situation, reporting via E&E News that the Danube is drying up and Europe still lacks a comprehensive plan to address this recurring risk. Future developments depend on the success of Romania's efforts to boost water levels and the continued capacity of the Kozloduy NPP in Bulgaria. Observers are watching whether additional reactors across the region will be forced offline as the heatwave persists. The lack of a centralized European plan, as highlighted by POLITICO Pro, suggests that individual nations will continue to implement ad hoc measures to maintain power generation amid fluctuating river levels and increasing climate volatility.
