Introduction to Argentina's Nuclear Program

Argentina has 3 nuclear power plants in operation: Atucha I, Atucha II, and Embalse. [1] Atucha I has a net capacity of 340 MW (megawatts), Embalse has a net capacity of 608 MW, and Atucha II (see Fig. 1) has a net capacity of 693 MW. [1] Together, the 3 plants have a total capacity of 1641 MW.

Argentina's nuclear program has not kept pace with the rate of growth of other forms of energy. In 1990, Argentina produced 6.72 TWh (terawatt-hours) of nuclear electricity. [1] This accounted for 19.8% of total electricity production. [1] In 2021, Argentina produced 10.17 TWHh of nuclear electricity, a 51% increase. [1] However, other forms of energy increased more quickly such that in 2021, nuclear power plants only accounted for 7.2% of electricity production. [1]

Additionally, Argentina's plants have faced issues. Most notably, Atucha II was non-operational during most of 2023 due to a collapse of one of the reactor's metal internal supports. [2] Atucha II was operational again as of August 2023, but was non-operational for 10 months, and the repairs cost $20 million. [2]

Atucha III

Cristina Fernandez is an Argentinian left-wing politician in power from 2007 to 2015. [3] During her administration, she was known for striking several deals with China. [3] One such deal was a contract with China to build Atucha III, a third nuclear power plant built in the same location as Atucha I and Atucha II. [3] Cristina Fernandez left office in 2015, after which progress on the deal stalled. [3] The new president, Mauricio Macri, took a hard line on China, which may have contributed to the stalled deal. [3]

Mauricio Macri was succeeded by Alberto Fernandez in 2019, who was more friendly to China. On February 1st, 2022, Chinese media announced that the state-owned China National Nuclear Corp signed a contract with Argentina to build Atucha III. [4] The projected cost is $8 billion. [4] Atucha III will be built according to the Hualong One model, a pressurized water nuclear reactor power plant developed by the Chinese government. [4] There is currently only one operational Hualong One reactor, which is in Fujian, China. [4] Argentina and Pakistan are the two overseas countries currently constructing Hualong One reactors. [4] Argentina's government stated that Atucha III will have a gross capacity of 1,200 MW. [4] If we assume that Atucha III has a net capacity of at least 1,000 MW, this would increase Argentina's net nuclear capacity from 1,641 MW to 2,641 MW, a 60.9% increase.

The president of Argentina since December 2023 is Javier Milei. [5] Milei is known for opposing high government spending. Additionally, he opposes deeper ties with China. [5] As of February 2024, Atucha III's plans remain in place. However, Milei has taken action in other energy sectors. He has declared a power sector emergency, to decrease energy price controls and take power away from gas and electricity regulators. [6] It is possible that Argentina's nuclear policy will see another about-face.
