Paks nuclear plant targets full output by Wednesday

Nuclear power plant cooling towers by a river as electricity output ramps back to full capacity

Key Points

01Paks nuclear plant has reconnected Turbine 6 of Unit 3 to the grid
02Turbine 6 is being ramped from 22 MW toward 240 MW of output
03The plant is expected to reach 2,000 MW nominal capacity by Wednesday
04Emergency works and higher Danube levels have eased cooling limits

Paks begins restoring nuclear output

Hungary’s Paks nuclear power plant has started to restore generation after recent cooling constraints, with Turbine 6 of Unit 3 reconnected to the national grid late on Saturday. The unit resumed operation at 22 megawatts, marking a step in bringing more capacity back into service.

Plant operators are increasing Turbine 6’s output by one megawatt per minute, with the immediate target set at 240 megawatts. This controlled ramp‑up is part of a broader effort to rebuild the plant’s overall contribution to Hungary’s power system.

Planned return to full nominal capacity

Prime Minister Péter Magyar said the Paks facility could reach its nominal capacity of 2,000 megawatts by Wednesday if operations continue as planned. He also stated that all eight turbines are expected to be back in operation by that time, implying a near‑term normalization of nuclear output.

Two separate reports indicate that Paks normally generates around half of Hungary’s electricity. In that context, the planned return to full capacity would restore a major share of the country’s typical baseload generation.

Improved cooling from Danube works

Magyar cited emergency construction measures and natural changes in the Danube’s level as key factors improving reactor cooling conditions. These steps have allowed the plant to safely advance efforts to increase production.

A partially completed weir and the deployment of two barges have raised the water level at the plant’s location by about 15 centimetres. The higher river level has eased the cooling restrictions that had constrained output, supporting the gradual restart of turbines such as Unit 3’s Turbine 6.

Implications for Hungary’s power supply

With Turbine 6 ramping up and all eight turbines expected to be in service by mid‑week, the nuclear plant is on track to regain its nominal 2,000 megawatt capacity. This would significantly reinforce the stability of Hungary’s electricity supply after a period of reduced nuclear generation.

Given Paks’ usual role in providing a large share of national electricity, the restoration of capacity is a central development for the country’s power mix. The combination of technical remediation and river‑level management has been instrumental in enabling this rapid return toward full operation.

Key Takeaways

01Paks is moving from constrained operation toward its 2,000 MW nominal capacity within days, signaling a rapid normalization of nuclear output.
02Emergency river‑engineering measures, including a weir and barges, have been decisive in lifting Danube water levels enough to ease cooling limits.
03With all eight turbines expected back online, Hungary stands to regain a key source that typically accounts for a large portion of its electricity supply.
