Daniel Beneš, Chairman and CEO of CEZ, stated: “This is a step that significantly increases the energy security of the Czech Republic.” He further noted: “In addition to diversifying nuclear fuel suppliers, we also hold strategic reserves in both of our nuclear power plants.” CEZ, the Czech utility, signed a contract with Westinghouse in 2023 for Dukovany’s fuel supply, following a 2022 agreement with Westinghouse and Framatome for the Temelín plant. The Dukovany delivery includes Westinghouse’s NOVA E-6 design for VVER-440 reactors, while Temelín uses the Robust Westinghouse Fuel Assembly.
The 80 fuel cartridges delivered to Dukovany are undergoing rigorous safety checks and require approval from the national regulator before being loaded into the reactor. The new fuel is designed to support extended fuel cycles of 16 months at Dukovany and 18 months at Temelín, improving efficiency. Tarik Choho, President of Westinghouse’s Nuclear Fuel Division, said: “Westinghouse supplied VVER-1000 fuel to both Temelín units from 2000 to 2010. As the largest supplier of VVER fuel in Europe, we have continued to invest in advanced fuel designs to support energy security in the region. These fuel deliveries are a testament to our shared commitment to safety, reliability, and supply diversification for VVER reactors.” The fuel, manufactured in Västerås, Sweden, is compatible with other manufacturers’ assemblies and offers enhanced efficiency.
The Czech Republic generates about one-third of its electricity from nuclear power, with four VVER-440 units at Dukovany, operational since 1985–1987, and two VVER-1000 units at Temelín, operational since 2000 and 2002. The diversification of fuel suppliers strengthens the country’s energy security, aligning with broader European efforts to ensure stable nuclear fuel supplies.
