The Paks II nuclear power project in Hungary has marked a significant milestone by officially commencing construction with the first concrete pour. This development qualifies the project as an active nuclear build under the criteria established by the International Atomic Energy Agency (IAEA). The transition from planning to construction reflects Hungary’s commitment to enhancing its nuclear capacity amid a complex European energy landscape.
During the ceremony, Foreign Minister Péter Szijjártó emphasized the importance of expanding nuclear energy, particularly as Europe grapples with political resistance towards nuclear power. He noted that increasing electricity demand and the necessity for stable, weather-independent generation have shifted perceptions, positioning nuclear energy as a viable solution for maintaining competitiveness and ensuring industrial stability.
The Paks II project is being executed in collaboration with Russia’s Rosatom, which views the initiation of construction as both a symbolic and practical demonstration of Hungarian-Russian cooperation. Once completed, Paks II will be notable for being the first facility in the European Union to utilize modern VVER-1200 Generation III+ reactors. The initial concrete pour serves as the foundation for the future control building of Unit 5, while subsequent phases will involve constructing reactor structures, implementing double containment systems, and incorporating advanced safety technologies like a core catcher designed for severe accident management.
For Hungarian officials, Paks II is not merely about generating new electricity; it is also seen as a strategic move to protect the country from volatile energy markets. The government anticipates that these reactors will help maintain regulated household energy prices and enhance supply security. Furthermore, nuclear expansion is framed as a means to keep long-term energy costs manageable for consumers.
Looking ahead, following the issuance of final foundation permits by the Hungarian Atomic Energy Authority in November 2025, construction activities are expected to accelerate. Authorities regard the eventual commissioning of Paks II as a crucial step towards achieving greater energy self-sufficiency for Hungary.
