The Hungarian government has initiated a review of the Paks II nuclear power plant expansion project, a major agreement with the Russian state corporation Rosatom. Prime Minister Péter Magyar raised concerns regarding the project’s economic justification, technical design, and adherence to timelines, specifically noting the lack of a closed-loop cooling system and the significant funds already spent on a site that remains largely undeveloped.

While Rosatom has defended the project, claiming construction is proceeding according to schedule, the situation has escalated into a criminal investigation. Hungarian police, through the National Investigation Bureau’s Corruption and Economic Crime Department, are investigating a nearly 80 billion forint capital increase related to the project. 

The probe focuses on a payment made by the Hungarian state to the Russian contractor Atomstroyexport. This transaction occurred after the Court of Justice of the European Union annulled the European Commission’s approval of state aid for the project due to concerns over EU procurement rules. Investigators are looking into suspicions of a breach of trust that may have caused significant financial loss.
