Danube Drought Forces Romania and Hungary to Shut Nuclear Reactors

The outages remove large shares of baseload power, raising the risk of evening blackouts as heat drives up air‑conditioning demand.

Overview

  • On Friday, Romania took both 706 MW reactors at Cernavodă offline and declared a nationwide state of emergency for August after river levels fell below cooling thresholds.
  • Hungary announced a full shutdown of its Paks plant, the first complete stoppage in the 44‑year facility's history, because the Danube no longer supplies enough cooling water.
  • Both countries are pursuing short‑term fixes: Romania approved funds to divert water into cooling channels and opened talks to import electricity from neighboring states.
  • Budapest has ordered industrial and public savings, prepared legal measures for targeted outages, and warned that losing roughly 2,000 MW from Paks will sharply increase import needs and costs.
  • Low Danube flows are also halting inland shipping and causing local drinking‑water shortages, showing how drought-driven river lows can cascade into energy, transport, and municipal services.
