Paks Nuclear Power Plant is the only operational nuclear power plant in Hungary. Located near the town of Paks on the banks of the Danube, it is a critical component of the national energy strategy. The facility has been a cornerstone of the country's electricity generation since the 1980s, operated by MVM Paksi Atomerőmű Zrt. under the state-owned MVM Group.

History

The decision to construct the facility was made by the Hungarian Socialist Workers' Party government in the late 1960s, following agreements within the Comecon framework. Initial site preparation and construction, led by Soviet design institutes and Atomstroyexport, began in the early 1970s. The project was a major element of energy cooperation between the People's Republic of Hungary and the Soviet Union. The first reactor was connected to the Hungarian power grid in 1982, with subsequent units coming online throughout the decade.

Technical specifications

The plant comprises four pressurized water reactors of the Soviet-designed VVER type, specifically the VVER-440/V213 model. Each reactor has a thermal capacity of 1,375 MW and a net electrical output of approximately 475.5 MW, for a total installed capacity of 1,902 MW. The primary coolant circuits and steam generators were supplied by Škoda Works and Ganz Works. The design includes a full containment building and other safety features developed following the Chernobyl disaster. The turbines were manufactured by the Leningrad Metal Plant.

Operational history

Since achieving full commercial operation, the plant has consistently provided a large share of Hungary's domestic electricity production. Major operational milestones include numerous International Atomic Energy Agency reviews and safety upgrades. A significant incident occurred in 2003 during fuel rod cleaning in the second unit's cooling system, which led to a partial fuel assembly damage and required an extended outage. The event was classified on the International Nuclear Event Scale and prompted comprehensive safety enhancements across the station.

Safety and environmental impact

Safety oversight is conducted by the Hungarian Atomic Energy Authority in accordance with European Union directives and International Atomic Energy Agency standards. Post-Fukushima Daiichi nuclear disaster stress tests were performed, leading to further investments in backup systems. Environmental monitoring of the Danube and surrounding areas in Tolna County is continuous, with radiation levels consistently reported as normal. The plant's operations produce negligible greenhouse gas emissions compared to fossil fuel power stations.

Expansion and future plans

The Government of Hungary has approved the construction of two additional reactors, Paks II. A contract was awarded to Rosatom for the engineering, procurement, and construction of two VVER-1200 units. The project has undergone review by the European Commission regarding compliance with Euratom treaty rules. Preparatory works, including agreements with Bechtel and Framatome for certain components, are underway, though the project has faced political and financing challenges within the European Union.

Economic and energy significance

The facility is fundamental to the national energy mix, typically generating over 50% of the country's electricity. This contributes significantly to energy security and price stability, reducing dependence on imported natural gas. The plant is a major employer in the Paks region and supports a network of domestic suppliers and institutions like the Budapest University of Technology and Economics. Its output is crucial for meeting Hungary's commitments under the Paris Agreement and European Green Deal carbon reduction targets.
