Romania Boosts Danube Flow to Safeguard Cernavoda Nuclear Plant
8/23/2026, 12:19:46 AM
Emergency Measures Approved (August 22)
- Romania’s National Committee for Emergency Situations approved a package of emergency actions to raise the Danube water level near the Cernavoda nuclear power plant, which has been offline since late July because low river levels prevented adequate cooling water intake.
- The plan includes:
- Emergency dredging of the Danube channel adjacent to the plant.
- Construction of a groyne along the Old Danube to divert water toward the plant’s intake.
- Deployment of high-capacity pumps to maintain the required water level.
- A five-day release of water from Hidroelectrica’s reservoirs on the Olt River.
Background: Record-Low Danube Levels Across Europe
- An unprecedented heat wave has driven the Danube to historically low flows, disrupting navigation, agriculture, and energy production along its 2,850 km course.
- Neighboring countries have already taken similar steps: Bulgaria’s Energy Ministry announced a preventive reduction of about 120 MW at Kozloduy’s Unit 5 on August 21—the first such cut in the plant’s 52-year history. Hungary’s Paks nuclear plant is operating at roughly 25 % capacity after emergency engineering works.
Data & Statistics
- Hidroelectrica will release an additional average of 50 cubic meters of water per second from Olt River reservoirs for five days, both to bolster Danube flow and to generate extra electricity.
- The exact water-level target needed for Cernavoda’s cooling system has not been disclosed.
Official Statements & Responses
- The Romanian government press office said the emergency measures are essential to secure the cooling water supply required for safe reactor operation and to avoid a prolonged electricity shortage during the state of emergency declared for August.
- Bulgaria’s Energy Ministry described its output reduction as a preventive step to ensure safe operation of Kozloduy under “extreme weather conditions.”
Why It Matters
- Cernavoda provides a substantial share of Romania’s electricity; its shutdown has forced the country to import power and triggered a nationwide heightened alert for the energy sector.
- Maintaining nuclear output is critical for regional grid stability, especially as low river levels raise energy prices by curtailing river-borne freight and hydro-electric generation.

What’s Next
- The five-day water release from Olt River reservoirs is scheduled to begin on the Saturday following the August 22 approval and will be monitored for effectiveness. Romanian authorities have indicated that additional engineering works, such as the groyne, will proceed if water levels remain insufficient.
