The Atucha Nuclear Complex, or Atucha Nuclear Power Plant, is the location for two adjacent nuclear power plants in Lima, Zárate, Buenos Aires Province, about 100 kilometres (60 mi) from Buenos Aires, on the right-hand shore of the Paraná de las Palmas River. Both are pressurized heavy-water reactors (PHWR) employing a mixture of natural uranium and enriched uranium (0.85% of 235U), and use heavy water for cooling and neutron moderation.
The other currently operating nuclear power plant in the country Embalse Nuclear Power Plant is also a natural uranium fueled PHWR but of the Canadian CANDU 6 type rather than the Siemens provided type used at Atucha.
