Paks, a small Hungarian town on the shore of the River Danube an hour or two south of Budapest has prospered from its nuclear power station, built by the Soviet Union in the mid-1980s. Hungary has prospered too. Paks provides some 40 per cent of the country’s power requirements. But the four reactors are now approaching the end of their lives and are scheduled for closure in 2032; so in 2014 agreement was reached with Russia to build two more, with the help of a Russian loan, Russian engineers, and a small army of Ukrainian welders. But the invasion of Ukraine by the Russian army in February 2022 has thrown these plans into disarray. Construction has begun, in the sense that bulldozers have been clearing the ground. But the project is already delayed, and there are those who believe that the new reactors will never be built. As Nick Thorpe discovers, people who thought they had a job for life in Paks are worried about their future and the future of a town whose lively shops and restaurants owe everything to the nuclear industry. Now the centre-piece of prime minister Viktor Orban’s energy empire, Paks may soon become the country’s rustbelt.
