Russia’s TVEL completes development of the new nuclear fuel modification for Hungary’s Paks NPP

Russian nuclear fuel cycle company TVEL has completed the project of development and validation of the new nuclear fuel modification for the VVER-440 reactors operated at the Paks Nuclear Power Plant in Hungary.

“TVEL Fuel Company of ROSATOM and Paks NPP have a long-time partnership with a number of successfully accomplished projects,” said Natalia Nikipelova, President of TVEL. “The introduction of the new fuel modification at all four power units of the plant would enable our customer to decrease gradually the fuel share in the power generation cost, giving an essential economic impact. Paks NPP contributes about the half of the whole electricity generation in Hungary and for us, as a nuclear fuel manufacturer, it is a matter of professional pride to provide the Hungarian nuclear power units with reliable supplies of the fuel which would be both high-quality and commercially attractive.”

The new modification of VVER-440 second generation fuel would optimise the hydro-uranium ratio in the reactor core, enabling to increase the efficiency of fuel usage and advance the economic performance of the power plant operation.

Although a coal phase-out is already planned, Hungary keeps relying on nuclear power, which today accounts for 48 per cent of the energy mix.

During the Budapest Climate Summit, Pál Kovács, State Secretary for the maintenance of capacity of the Paks NPP highlighted the importance of nuclear power for the country to fulfil its climate goals.

“The modernisation will not slow us down but helping in the directions of new technologies like hydrogen,” he said. “The new plant will save millions of tonnes of carbon emissions as well as helping the transport sector.”
