The Atucha nuclear power plant in Lima, Buenos Aires province, is a symbol of Argentina's technological development and its long history in the peaceful use of nuclear energy. It consists of two reactors, Atucha I and Atucha II, located on the banks of the Río Paraná de las Palmas. Atucha I was the first nuclear power plant in Latin America and was commissioned in 1974. Both reactors are heavy water reactors that can be operated with natural uranium, a technology that Argentina has mastered over decades. The plant makes an important contribution to the national electricity supply and is a center for scientific and technological research. Safety protocols are strict, and the power plant plays a key role in Argentina's strategy to diversify the energy matrix and reduce CO2 emissions.
