Hungary: Paks reactor increases electricity production

Hungary’s nuclear power plant at Paks has resumed electricity generation earlier than planned, according to Prime Minister Péter Orbán, who announced the decision on social media. The resumption came after efforts to secure cooling water supply, which had been a key constraint on operations. The move marks a critical step toward addressing the country's looming energy crisis. The Paks Nuclear Power Plant, located in southern Hungary, began increasing its output this evening. Initially, reactor block 3 was brought back online, with plans to restart all four reactors by August 28. Each reactor operates at a capacity of 2,000 megawatts, meaning the entire facility could generate up to 8,000 megawatts once fully operational. This would significantly bolster the national grid, which has faced strain due to reduced production from other sources. Previously, only reactor block 2 had been operating at 25 percent capacity, running just two of its eight turbines. The limited output had raised concerns over meeting energy demands during peak periods. With the resumption of block 3, the plant is now producing more electricity than before, though not yet at full capacity. To facilitate the restart, emergency measures were taken. Two cranes, each 80 meters long, were submerged into the Danube River to raise the water level near the plant. Additionally, work began on constructing a sump wall using approximately 150,000 cubic meters of rock. These actions helped ensure sufficient cooling water for the reactors, a crucial requirement for safe operation. Defense Minister Romulusz Ruzsin-Szendi emphasized the smooth execution of the sump wall project, noting that military personnel played a key role. He described the effort as both technical and strategic, highlighting its importance for national security and stability. The Paks plant, originally built by the Soviet Union and commissioned in 1982, continues to provide roughly half of Hungary’s electricity. It remains a vital part of the country’s energy infrastructure despite ongoing debates over safety and environmental impact. At the same time, the construction of two new reactor blocks, part of the Paks II project, is underway. This expansion is being funded through Russian loans and managed by the state-owned Russian firm Rosatom. The Paks II project has drawn international attention, with some critics raising concerns over reliance on Russian financing and technology. However, Hungarian officials have defended the initiative as essential for securing long-term energy independence. The recent resumption of operations at the existing plant underscores the government’s commitment to maintaining stable electricity supplies amid rising demand and geopolitical uncertainties. With all four reactors set to reach full capacity by mid-August, the plant will contribute substantially to Hungary’s energy needs. The success of these efforts will depend on continued maintenance of the cooling system and adherence to strict safety protocols. As the nation watches the progress, the outcome of this phase could influence future energy policy decisions.
