Danube Drought Triggers Historic Nuclear Shutdowns in Hungary and Emergency Water Diversion in Romania

Core Event: Record-Low Danube Forces Hungary’s Paks Plant to Shut Down and Romania to Explode Rock for Water Diversion
In early August 2026, low water levels in the Danube forced Hungary’s 2-GW Paks nuclear plant—the country’s sole nuclear source—to cease operations for the first time in its 44-year history. At the same time, Romania’s navy detonated a 180-kg charge to blast a rock in the Bala canal, creating a temporary dam that redirects Danube water toward the Cernavoda site, which is operating with only one reactor.
Background & Context
A heatwave and months of below-average rainfall have driven the Danube to historic lows. The river supplies cooling water to both nations’ reactors; when levels fall, intake pumps cannot draw sufficient water, triggering safety-driven reductions. Hungary’s Paks plant had already been operating at just over 10 % of capacity before the final shutdown. Romania declared a state of emergency after the Cernavoda plant lost one reactor to the same shortage.
Data & Statistics
- Paks output: normally ~2,000 MW; reduced to 240 MW before total shutdown.
- Danube level in Budapest: 23 cm, well below the previous record low of 33 cm (2018).
- Romanian explosion: 180 kg of explosives used to dislodge a rock, enabling a temporary dam.
- Voluntary demand cuts: Hungarian households and companies cut 700 MW; Romanian car makers halted production, cutting about 200 MW; Richter reduced use by >50 % and added 4 MW from its solar park.
Official Statements & Responses
Prime Minister Péter Magyar warned that “the most critical five days” were beginning and that the grid and public services would face “enormous strain.” He announced a decree allowing MAVIR to impose mandatory cuts on large industrial users if voluntary measures proved insufficient. Romanian Prime Minister Ilie Bolojan cited “drought-related difficulties” and limited trans-border connections. Deputy director of Paks Laszlo Nagy called the situation “unprecedented” and said the plant could remain offline for weeks. Slovak Prime Minister Robert Fico expressed solidarity and readiness to assist.
On-the-Ground Reports
Local residents reported exposed riverbeds, shipwrecks and a mammoth skeleton, underscoring the drought’s severity.
Conflicting Reports & Gaps
Media differ on the shutdown timeline. Reuters and the Financial Express quoted Magyar suggesting the last turbine could run “today, and maybe tomorrow,” while Bloomberg reported the plant might stay offline for “several weeks.” Forecasts also vary, with some indicating a short-term rise in water levels and others projecting continued decline.
Verbatim Quotes
- “As a result, the plant is now producing only 240 megawatts (of electricity), and tomorrow (on Sunday), for the first time in 44 years, it will be completely shut down,” — Péter Magyar
- “We are facing the most critical five days ahead,” — Péter Magyar
- “The power grid, our public services and ourselves will all come under enormous strain,” — Péter Magyar
- “I am closely monitoring the energy crisis in Hungary and express our full solidarity ?with our neighbour, along with our readiness to help,” — Robert Fico
What’s Next
Hungary will decide whether to enforce mandatory cuts after Sunday’s appeal; the decree already permits MAVIR to disconnect non-compliant users. Projections suggest the Danube will stay below critical thresholds for weeks, potentially keeping Paks offline for an extended period. Romania aims to complete the temporary dam by Wednesday, after which the remaining Cernavoda reactor may resume limited operation. Both countries continue to rely on electricity imports and industrial reductions to stabilize their grids while the heatwave persists.
