Argentina's nuclear programme has been highly successful. In 1957 Argentina was the first country in Latin America to design and build a research reactor with homegrown technology, the RA-1 Enrico Fermi. This reliance in the development of own nuclear related technologies, instead of simply buying them abroad, was a constant of Argentina's nuclear programme conducted by the civilian National Atomic Energy Commission (CNEA). Nuclear facilities with Argentine technology have been built in Peru, Algeria, Australia and Egypt. In 1983, the country admitted having the capability of producing weapon-grade uranium, a major step needed to assemble nuclear weapons; since then, however, Argentina has pledged to use nuclear power only for peaceful purposes. As a member of the Board of Governors of the International Atomic Energy Agency, Argentina has been a strong voice in support of nuclear non-proliferation efforts and is highly committed to global nuclear security. In 1974 it was the first country in Latin America to put in-line a commercial nuclear power plant, Atucha I. Although the Argentine built parts for that station amounted to 10% of the total, the nuclear fuel it uses are since entirely built in the country. Later nuclear power stations employed a higher percentage of Argentine built components; Embalse, finished in 1983, a 30% and the 2011 Atucha II reactor a 40%.
