Romania Boosts Danube Waters to Ensure Cooling at Cernavoda Nuclear Plant

Emergency Measures to Address Low Danube Levels and Nuclear Plant Cooling

WARSAW, Aug 22 (Reuters) - Romania's National Committee for Emergency Situations approved new measures to boost the water level of the River Danube and ensure cooling of the Cernavoda nuclear power plant, the government press office said on Saturday.

Impact of Low Danube Levels on Cernavoda Nuclear Plant

The plant remains shut due to historically low Danube levels and the country has declared a ​state of emergency ‌throughout August stemming from a decline in electricity ​production.

Key Emergency Actions Implemented

  • Danube Dredging Operations
    Emergency dredging of the Danube course in the plant area is planned.
  • Construction of Groyne on Old Danube Channel
    Along the Old Danube channel a groyne will be built to divert water towards the area of the water intake for the cooling systems of the plant.
  • Supplementing Danube Flow from River Olt
    Hydro plant operator Hidroelectrica will begin releasing water from reservoirs on the River Olt on Saturday for five days to supplement Danube flow and generate extra electricity.
  • Deployment of High-Capacity Pumps
    High-capacity pumps will be mobilized to maintain, if needed, the water level necessary for the operation of the plant.

Key Takeaways

  • Authorities are conducting emergency dredging and constructing an epiu/groyne to redirect Danube flow toward Cernavodă’s cooling intake (libertatea.ro).
  • Hidroelectrica will release around 50 m³/s of water from Olt reservoirs for five days to boost Danube flow and support electricity generation (libertatea.ro).
  • High-capacity pumps and military-supported subaquatic operations are in place to maintain minimum water levels required for reactor cooling amid one of the lowest Danube flow periods in decades (libertatea.ro).
