In Argentina, about 10% [1] of the electricity comes from 3 operational nuclear reactors: Embalse, a CANDU reactor, and Atucha I and II, two PHWR German designs.
In 2001, the Atucha plant was modified to burn Slightly Enriched Uranium, making it the first PHWR reactor to burn that fuel worldwide.[citation needed] Atucha was originally planned to be a complex with various reactors. Atucha 2 (similar to Atucha 1 but more powerful) began to produce energy on June 3, 2014, and it is expected to produce 745MWh[clarification needed]. Plans for Atucha III, a third reactor in the Atucha complex, have been announced.[2]
Argentina also has various research reactors,[3] and exports nuclear technology. Nucleoeléctrica of Argentina and Atomic Energy of Canada Limited are negotiating over the contracts and project delivery model for a new 740 MWe CANDU nuclear power plant.[4]
In July 2014, Russian President Vladimir Putin signed a nuclear energy cooperation agreement with Argentine President Cristina Fernández Kirchner, during a visit to the country.[5]
In February 2015, Argentine president Cristina Kirchner and Chinese Communist Party general secretary Xi Jinping signed a cooperation agreement, and the build of a Hualong One design power station has been proposed.[6][7]
In December 2015 a new uranium enrichment plant to manufacture fuel for Argentina's nuclear plants, located in Pilcaniyeu, was inaugurated. The plant will use both gaseous diffusion and more modern laser techniques.[8]
China and Argentina had agreed a contract to build a 700 MWe CANDU 6 derived reactor. Its construction was planned to start in 2018 at Atucha,[9][10] but it was indefinitely suspended by Mauricio Macri's government due to financial issues.[11] The building of a 1000 MWe Hualong One plant is planned to start in 2020.[10]
