Severe drought and record-low Danube water levels have starved Romania's Cernavodă nuclear plant of cooling water, forcing the shutdown of Reactor Unit 1 and threatening Unit 2. Romanian naval forces carried out controlled explosions and sank barges along the river to redirect flow toward the plant, buying at least nine more days of operation as of August 9. Hungary's Paks plant faces a similar squeeze, highlighting how drought is straining nuclear-dependent power grids across the region.

  • Record-low Danube water levels have already forced the shutdown of Cernavodă's Unit 1 reactor, leaving Unit 2 as Romania's only operating nuclear unit.
  • Romanian naval forces conducted controlled explosions and sank four barges in the Danube's Bala arm to redirect roughly 50 cubic meters of water per second toward the plant.
  • The intervention raised water levels by about 4-8 centimeters, extending Unit 2's operation by at least nine days as of August 9, though officials warn river currents could still dislodge the barges.
  • Officials and the IAEA stress that reduced output or shutdowns from cooling-water shortages do not indicate unsafe conditions, and a Chernobyl-type event is described as impossible; Hungary's Paks plant faces a similar drought-driven capacity cut.

How it unfolded

  1. Analysis Unit 2 marks 19-year anniversary amid crisis

    Romanian outlet G4Media notes Cernavodă's Unit 2 — now the plant's only operating reactor — turns 19 years since first grid connection, as officials warn strong currents could dislodge the barges and erase the gained water flow.

  2. Report Reactor output extended nine more days

    Bloomberg reports the explosive works raised Danube flow by about 4cm, allowing Romania to keep the second Cernavodă reactor running for at least nine more days.

  3. Reaction Online panic over 'nuclear' and 'reactors unable to cool' headlines

    LADbible describes public alarm at coverage of the plant, with Nuclearelectrica and IAEA officials moving to reassure that a Chernobyl-type event is not a risk.

  4. Event Barges sunk to redirect Danube flow

    Authorities controlled-sink four barges in the Bala arm of the Danube, creating artificial thresholds to redirect more river flow to the plant's intake.

  5. Event Romanian navy detonates part of the Danube

    Semafor reports Romanian naval forces blew up part of the drought-hit Danube river to help cool the Cernavodă nuclear plant.

  6. Report Drought hits nuclear plants in Romania and Hungary

    DW reports Hungary's Paks plant is running at about 10% capacity and Romania's military has blown up a rock outcrop to improve Danube flow to Cernavodă.
