Hungary’s Paks Nuclear Plant Nears Full Capacity After Emergency Danube Measures
8/23/2026, 9:16:58 PM
Core Event: Accelerated Reactor Restarts
Prime Minister Peter Magyar announced on August 23 that the Paks nuclear facility is on track to resume its full 2,000-megawatt output by the upcoming Wednesday, a day or two earlier than the schedule originally communicated. Reactor 3 was brought back online late on Saturday, and two turbines are already generating electricity, with a third turbine expected to connect to the grid imminently.
Background & Context: Drought-Induced Water Shortage
A prolonged heat wave across Europe dried the Danube River, lowering water levels to historic lows. Because the river supplies cooling water for Paks, the plant was forced to cut output to just over 10 % of capacity in early August. Emergency engineering actions—including the sinking of two barges on August 15 and the construction of an underwater “bottom sill” approved on August 12—were deployed to raise the river’s level at the plant’s intake.
Data & Statistics
- Design capacity: 2,000 MW (eight turbines).
- Current output: about 800 MW, according to the plant operator.
- Share of national electricity: roughly 40 % of Hungary’s total generation.
- Water-level change: the emergency works lifted the Danube at Paks by approximately 15 cm, improving conditions for cooling.
Official Statements & Responses
- Peter Magyar (Prime Minister) emphasized that the rising water level and the bottom-sill construction enabled the earlier-than-planned restart of Unit 3. He framed the measures as essential to “save” agriculture and to prevent broader energy shortages.
- Istvan Kapitany (Minister of Economy and Energy) reported on social media that the temporary weir raised the river by 15 cm and that no operating turbines needed to be shut down, allowing a full-capacity return in the second half of the following week.
- Károly Vigh (Plant director of operations) described the turbine-restart procedure as a 49-hour process, noting that the turbine is initially turned at 3–4 rpm to avoid shaft bending before being accelerated to its operating speed of 3,000 rpm.
Conflicting Reports & Gaps
Sources differ on the exact date when full capacity will be achieved. The Prime Minister’s August 23 briefing cites Wednesday as the target, while the Minister of Economy and Energy projects a return to full output “around next Thursday or Friday.” No source provides a definitive timeline for the completion of the bottom-sill project beyond the current 231-metre stretch on the left bank.
