BUDAPEST — Work on the Russian-financed expansion of a Hungarian nuclear plant will begin in January, Hungary’s foreign minister said on Monday after talks in Budapest between Prime Minister Viktor Orban and Russian President Vladimir Putin.

Building work on two new reactors at the Paks facility outside Budapest had been delayed as the EU examined the project’s legality, but "now nothing can stop the construction," said Peter Szijjarto according to the Hungarian news agency MTI.

After closed-doors talks between Orban and Putin on the sidelines of the World Judo Championships in Budapest, Szijjarto told reporters that work will begin in January.

The 10 billion euros (US$12 billion) expansion will be mostly carried out by Moscow’s state-owned Rosatom and is to be financed largely with a Russian loan according to a deal signed by the two leaders in 2014.

The two 1,200 megawatt reactors at the plant in Paks, 100 kilometres south of Budapest, will more than double its capacity.

The plant is the sole nuclear facility in the EU member, and currently provides around 40 per cent of its electricity needs.

Visiting Orban in Budapest for the second time this year, Putin, also an honorary president of the International Judo Federation, has hailed Hungary, which is also heavily dependent on Russian gas, as an "important and reliable partner for Russia in Europe".

The project has been criticised by anti-nuclear Austria which neighbours Hungary and has threatened to take the case to the European Court of Justice in Strasbourg.

The European Commission approved the Paks expansion project last March after judging that it met EU rules on state aid "on the basis of commitments made by Hungary to limit distortions of competition".

Brussels also dropped an infringement case after Hungary awarded the contract to Rosatom without holding an open tender.

EU authorities were under pressure to take a close look at the deal amid fears the Kremlin was using it to meddle further with the bloc’s sensitive energy sector.

The Hungarian parliament voted to keep the details of the deal secret for 30 years, something Orban’s ruling Fidesz party said was needed for "national security reasons" but which critics said could shield corruption. — AFP
