Szijjártó noted that an agreement had been reached with the Russian government and Rosatom on changes to the contract in April. Legal, technical and physical conditions have changed since the contract was signed more than nine years ago, he added. 

The clearance from the EC for the changes affecting the implementation and financing of Paks II will contribute to the "significant acceleration" of the project, he said, adding that operations could start "at the very beginning of the coming decade." 

Rosatom is the general contractor for constructing two more blocks at the Paks plant.

The four existing blocks at Paks account for about half of Hungary's domestic electricity generation.
