Low Danube Levels Slash Hungarian, Romanian Nuclear Output

Summary

Story summary

Low Danube water in August 2026 forced Hungary’s Paks and Romania’s Cernavoda plants to curtail output.
Paks runs at 12 % capacity with reactors offline, prompting Prime Minister Péter Magyar to ask users to cut electricity, saving 600–700 MW.
Romania’s water agency prepared four barges and detonated a rock to divert Danube water to Cernavoda.
Slovakia’s nuclear plants use cooling towers, keeping them operational, while Austria’s pumped-storage hydropower stayed less affected.

History

Historical Context

In summer 2003 Europe endured a record heatwave—its second-hottest year on record—that cut Danube discharge by about 30 % and forced nuclear stations of E.ON, EDF and Verbund to shed roughly 1.2 GW, prompting EU emergency water-use rules. The same drought pattern now threatens Hungary’s Paks and Romania’s Cernavoda reactors, underscoring growing reliance on resilient cooling and water-management strategies.
