Hungary Plans Danube Interventions to Sustain Paks Nuclear Plant
8/13/2026, 8:08:44 AM
Core Event
Hungary’s government will begin engineering work on the Danube River to raise water levels and protect cooling for the MVM Paks Nuclear Power Plant. Prime Minister Peter Magyar announced that a concrete “bed sill” will be installed upstream of the plant on July 29, 2026, and that two 80-meter barges may be sunk to add up to 20 centimetres of water depth. A decision on whether to sink the barges is slated for the following Friday.
Background & Context
The Soviet-built Paks plant supplies roughly one-third of Hungary’s electricity. Its reactors rely on Danube water for cooling. Persistent drought and heat waves have driven the river to record lows—the lowest in nearly 90 years—forcing the plant to run at a fraction of its 2,000 MW capacity. On August 2 a shutdown of Reactor 3 was announced, marking the first plant-wide shutdown in its 44-year history.
Data & Statistics
- Current output: just over 10 % of full capacity (approximately 200 MW).
- Economic impact: operating at this reduced level is estimated to cost the Hungarian economy up to 50 billion forints (? $158 million) per month.
- Intervention cost: the planned river works are budgeted at around 6 billion forints (? $19 million).
- Materials: delivery of about 145,000 cubic metres of rocks for the bed sill is scheduled to begin Wednesday evening.
Official Statements & Responses
He framed the bed sill as a “long-term” solution to prevent future shutdowns. Magyar also highlighted the economic burden of reduced output and positioned the river work as a cost-effective measure.
On-the-Ground Reports
Local footage posted by Magyar shows construction crews preparing the rock delivery and positioning barges near the plant. Observers note that the river’s water level had risen modestly after recent rain in the Austrian catchment area, offering temporary relief.
Conflicting Reports & Gaps
Sources differ on the plant’s operating capacity:
- ABC News reports the plant is at “little more than 10 %” of capacity.
- Baird Maritime notes the plant is operating at “around 25 %” with two turbines running.
No source provides a definitive forecast for how long the river-level interventions will sustain full cooling capacity.
Verbatim Quotes
- “We are already nine centimeters above the Danube’s Sunday low point, and rain is expected in the Austrian catchment areas.” — Hungary’s Magyar, prime minister
What’s Next
- A decision on sinking the barges is expected on Friday.
- Monitoring of Danube water levels will continue, with further engineering options under consideration if levels begin to fall again.
