Part of Low water levels in the Danube are affecting river navigation in Hungary.

How could low water levels in the Danube affect the Paks Nuclear Power Plant?

Already happening What happens if… A possibility worth considering, not a forecast.

Low Danube levels force Paks Nuclear Power Plant to cut production The extreme drought and high temperatures in Central Europe have caused the Danube River to reach historic low levels in Hungary. Because the Paks Nuclear Power Plant relies on water from the Danube for cooling its reactors, the reduced water intake has severely disrupted operations. Reports indicate that the plant has been forced to significantly reduce production, at one point operating at only 10 percent of capacity, and has faced complete shutdowns for safety reasons.

How it reaches Paks Nuclear Power Plant

Reported by news outlets

Tap any step to see the evidence behind it.

The facts so far

As reported. Each one links to where it comes from.

  • The water level in Budapest reached a historic low of 16 centimeters, with a forecast drop to about 13 centimeters.english.republika.mk
  • The Paks nuclear power plant was operating at one point at roughly 10 percent of capacity after low water levels forced all but one of its reactors offline.cnn.com
  • The plant was shut down completely on Thursday or Friday for safety reasons due to dropping Danube levels.english.news.cn
  • Authorities have sunk two barges, each about 80 meters long, near Paks to temporarily raise the level of the Danube by about 20 centimeters.english.republika.mk

Why it matters

The Paks Nuclear Power Plant is a critical piece of energy infrastructure for Hungary, generating nearly half of the country’s electricity. Its forced reduction in output contributes directly to a national energy crisis, requiring the government to create an energy supply operational unit to draw up contingency plans, which could include temporary restrictions on heavy industrial users.

This crisis is part of a broader climate emergency affecting Central and Eastern Europe. The low water levels are not isolated to the plant; they are also disrupting transport routes along the Danube, affecting tourism, and forcing farmers to lose significant portions of their harvest due to the compounding drought.

What we don't know yet

  • Will the planned permanent underwater barrier be sufficient to stabilize the Danube levels and restore full plant capacity?
  • What long-term adjustments will Hungarian authorities make to energy supply to compensate for reduced nuclear output?

What would change this answer

Significant rainfall occurs in the Danube basinThe water levels could recover, allowing the Paks Nuclear Power Plant to resume full or near-full operational capacity.
The planned permanent underwater barrier is delayed or failsThe plant will remain vulnerable to low water levels, prolonging the energy crisis and operational restrictions.
