The Embalse CANDU pressurized heavy water reactor (PHWR) is owned and operated by Nucleoeléctrica Argentina Sociedad Anónima (NASA). The single-unit CANDU 6 reactor, with a gross output of 648 MWe, was designed by AECL. Construction started in 1976, and the Embalse plant began commercial operation in January 1984.

In December 1982, fuel loading began, and Embalse was declared in service on January 20, 1984. As well as supplying electricity, Embalse is also used to produce Cobalt-60, a radioisotope that is used in medical and industrial applications.
