"If we're serious about achieving the 2050 carbon-neutral target, we'll have to at least double [nuclear energy] capacity," Szijjártó said.

He urged an end to "ideological and political" debates over the use of nuclear energy and pressed for a level playing field for nuclear power plants.

Szijjártó said Hungary would never agree to EU sanctions that hurt the country's cooperation in the area of nuclear energy with Russia. He added that the construction of new blocks at Hungary's Paks nuclear power plant would ensure the country has enough energy to sustain the pace of economic growth.
