Kazakhstan’s state-owned uranium producer, Kazatomprom, has entered into a long-term supply agreement with ČEZ, a. s., one of Central Europe’s largest energy companies, enhancing energy cooperation between Kazakhstan and the Czech Republic.

Under the seven-year deal, Kazatomprom will supply Kazakh natural uranium concentrates to ČEZ, with volumes sufficient to cover roughly one-third of the uranium requirements for Westinghouse-manufactured fuel assemblies used at the Temelín Nuclear Power Plant. The agreement reinforces the Czech Republic’s energy security and strengthens efforts toward clean and sustainable power generation.
The official signing ceremony was held at ČEZ headquarters in Prague, attended by senior executives from both companies. The deal is part of Kazatomprom’s broader strategy to diversify its sales channels and expand its presence in the European market.
“This is another important milestone in our mission to be a partner of choice for the global nuclear energy industry,” said Vladislav Baiguzhin, Chief Commercial Officer of Kazatomprom. “This partnership with ČEZ supports regional energy security while contributing to shared goals of decarbonisation and sustainability.”

ČEZ operates six nuclear reactors at its Dukovany and Temelín sites, which together generate around 36% of Czechia’s electricity. The company is a key player in the nation’s long-term energy plan, known as VIZE 2030, aimed at achieving net-zero emissions.
“Securing a partnership with Kazatompromdiversifies our portfolio of suppliers and have strategic importance for ČEZ and Czech Republic,” said Bohdan Zronek, Member of the Board and Chief of the Nuclear Energy Division at ČEZ. “It ensures that our nuclear power plants will continue to have a stable and reliable source of fuel, which is essential for meeting our energy needs and driving our decarbonisation plan (VIZE 2030) to achieve net-zero goals.”
Kazatomprom, the world’s largest uranium producer, accounted for approximately 21% of global primary uranium production in 2024. With all operations based in Kazakhstan, the company extracts uranium using in-situ recovery (ISR) technology, and maintains strong commitments to safety, environmental stewardship, and sustainability.
The Czech deal adds to a growing list of international collaborations for Kazatomprom, whose customers span Europe, China, South and East Asia, and North America. The company markets its uranium through long-term and spot contracts from its Astana headquarters and Switzerland-based trading arm, Trade House KazakAtom AG (THK).
