The Atucha nuclear power plant ( Spanish Central Nuclear Atucha , CNA ) in the vicinity of Zárate , in the province of Buenos Aires in Argentina, consists of two reactor blocks . The second Argentine nuclear power plant Embalse is located near the city of Embalse .
Block 1
Unit 1 went into operation on March 19, 1974. Most of the construction work was carried out by the German Kraftwerk Union AG. The power plant has a net electrical output of around 335 MW . Atucha-1 is a so-called heavy water pressure reactor (PHWR). The special thing about this type of reactor is that it can be operated with natural uranium, which does not have to be enriched (about 0.7% uranium-235 content), which, however, complicates the reactor design. Today the power plant uses slightly enriched uranium with a share of 0.85 percent, which has reduced the costs of power plant operation by around 40 percent. In 2000, Germany granted a Hermes guarantee for repair work in reactor block 1.
Block 2
Planning for Block 2 began in 1979, and construction began in 1981. After a construction period of 33 years, the nuclear power plant was completed in spring 2014. The reactor became critical for the first time on May 2, 2014. Originally started as a joint venture between CNEA (the national atomic energy authority) and Kraftwerk Union, it was stopped in 1994 for the time being. There was a lack of funds to complete the 81 percent power plant. In the same year, the CNEA's nuclear power plants were taken over by Nucleoelectrica Argentina SA, a subsidiary of the Ministry of Economic Affairs. In 2003, plans were finally presented according to which the reactor would be completed by 2014 for 400 million US dollars in cooperation with German, Spanish and Brazilian companies. The reactor was officially put into operation on June 27, 2014.
Atucha 2 is also a PHWR, but with an electrical output increased to 692 MW.

Blocks 3 and 4
The construction of a third and fourth power plant block was planned for 2006. On July 12, 2014, President Cristina Kirchner and Russian President Vladimir Putin signed an agreement on the participation of the Russian state nuclear energy agency RosAtom in the Atucha 3 project, which has been in planning since 2009 and is estimated at around 2.2 billion dollars The governments of Argentina and China signed an agreement to cooperate in the financing and construction of the Atucha 4 project. In June 2018, the Argentine government under Mauricio Macri decided to discontinue plans to build an Atucha 3 and Atucha 4 reactor .
Data of the reactor blocks
The Atucha nuclear power plant has a total of two blocks :
| Reactor block | Reactor type | Net power | Gross output | start of building | Network synchronization | Commercial operation | Shutdown |
|---|---|---|---|---|---|---|---|
| Atucha-1 | PHWR | 319 MW | 362 MW | 06/01/1968 | March 19, 1974 | 06/24/1974 | |
| Atucha-2 | PHWR | 692 MW | 745 MW | 07/14/1981 | 06/27/2014 | 05/26/2016 |
