The plant is a Pressurised Heavy Water Reactor (PHWR). It employs a mixture of natural uranium and enriched uranium (0.85% of 235U), with heavy water for refrigeration and moderation. It has a thermal power of 1,179 MWth, and generates 357 MWe of electricity, which is delivered at 220 kilovolts to the Argentine Interconnection System, supplying about 2.5% of the total electricity production (2005).
Atucha I was started in 1968 and began operation in 1974; it was the first nuclear power plant in Latin America. When nearly built in 1973, Atucha I was taken over by fifteen guerrillas for publicity purposes. They quickly overpowered five armed guards, and wounded two other guards whom they encountered while withdrawing.
