JSC National Atomic Company “Kazatomprom” (“Kazatomprom” or “the Company”) announces today that it has signed a commercial agreement to supply natural uranium to the Brazilian state company, Indústrias Nucleares do Brasil (INB).

Kazatomprom was successful in winning INB’s commercial competition to supply natural uranium hexafluoride for the needs of the Brazilian nuclear power industry (http://www.inb.gov.br/Acesso-a-Informacao/Licitacoes-e-contratos/Licitacoes). With this agreement, the Company reinforces the geographic diversity of its contract portfolio, highlighting the ongoing success of its revitalized marketing function.

Kazatomprom initially signed a contract with INB in 2018, following a similar competition. This new 2019 agreement is indicative of the Company’s reputation for reliability in the global nuclear supply chain and more broadly, it represents further strengthening of Kazakh-Brazilian cooperation in the peaceful use of atomic energy in the Latin American region.
