Paks · up close
The river did not run dry. The cooling-water intakes sit at a fixed height — once the Danube drops below them, the pumps cannot lift water. On top of that, the law caps the temperature of the water returned: 500 m downstream of the outflow channel the Danube may not exceed 30 °C. Together these two limits forced the plant back.

The plant's design basis assumed the 100-year minimum was more than 1 m higherthan the 2018 record. The current level has gone past that assumption.

The “schedule” is MAVIR’s own forecast, so the gap includes forecast error — on its own it does not prove deliberate saving, but it shows the direction well.
