Nuclear power in Argentina

In Argentina, about 10% 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. 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. Plans for Atucha III, a third reactor in the Atucha complex, have been announced.

Argentina also has various research reactors, 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.

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.

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.

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.

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, but it was indefinitely suspended  by Mauricio Macri's government due to financial issues. The building of a 1000 MWe Hualong One plant is planned to start in 2020.
