Uranium In Argentina: Resources, Demand And Perspectives For Nuclear Supply

Argentina reported about 40,000 tonnes of uranium (tU) as reasonably assured resources and inferred resources for the production cost category <130 US$/kgU in the OECD-NEA/IAEA classification scheme. These resources belong to the following projects: Sierra Pintada, Cerro Solo, Don Otto, Laguna Colorada, Laguna Salada, Meseta Central and Amarillo Grande. With three heavy water reactors in operation and an approximate installed capacity of 1.7 GWe, the current natural uranium requirements are about 220–250 tU per year. Based on various nuclear growth scenarios, it is estimated that by 2030 there will be a generation capacity of some 3,092 GWe for the reference case, with raw material needs of some 486 tU per year. Currently, there are no perspectives for local uranium production in the short term, and it is thought that uranium projects with identified resources must complete resource delineation and advance in technical pre-feasibility studies for the recovery of uranium. It is expected that Argentina continue meeting the uranium demand with imports in the next following years. In the Latin America region, both Brazil and Paraguay could be considered as potential uranium suppliers. In conclusion, despite the apparent growth prospects for the use of nuclear energy to generate electricity in Argentina, there are no immediate prospects for the provision of uranium oxide concentrates from domestic deposits for fuel fabrication. This has implications for supply and energy security.
