The National Atomic Energy Commission ((スペイン語:Comisión Nacional de Energía Atómica), CNEA) is the Argentine government agency in charge of nuclear energy research and development. The agency was created on May 31, 1950 with the mission of developing and controlling nuclear energy for peaceful purposes in the country. CNEA's facilities include the Bariloche Atomic Centre (in San Carlos de Bariloche), Constituyentes Atomic Centre (in the city of Buenos Aires), and Ezeiza Atomic Centre (in Ezeiza, Buenos Aires Province). CNEA operates research reactors at each of these sites. ==History== Officially established by President Juan Perón's Decree No 10.936, CNEA filled the need for a state organ to oversee the funding of the Huemul Project in Bariloche. Before CNEA came into being, the project was funded by the Dirección de Migraciones. In practice CNEA had only four members (Juan Domingo Perón, González, Mendé and Ronald Richter). In 1951, decree 9697 created another agency, the Dirección Nacional de la Energía Atómica (DNEA), also under González, to do research on atomic energy in Buenos Aires (González left CNEA in April 1952 and was replaced by Iraolagoitía) until 1955. After being assessed by two review panels in 1952, the Huemul Project was closed and Richter was no longer a CNEA member. Research in physics and technology continued in Bariloche, but no longer along Richter's original line. Admiral Oscar Armando Quihillalt was the first director of the National Atomic Energy Commission, and was also an important participant in the International Atomic Energy Agency.〔 In 1955, José Antonio Balseiro, a research scientist and member of the first review panel on the Huemul Project, took over the recently created Instituto de Física de Bariloche, now Instituto Balseiro, which used Richter's facilities in the mainland, but abandoned the buildings in Huemul Island. In 1956 Argentina's uranium resources were nationalized with the Commission controlling prospecting, production, and marketing. A yellowcake (uranium oxide) production capability was created that could support future plans for reactors. However, in accord with three presidential decrees of 1960, 1962 and 1963, Argentina supplied its initial production of about 90 tons of unsafeguarded yellowcake to Israel to fuel its Dimona reactor, creating the fissile material for Israel's first nuclear weapons. The facilities in Buenos Aires were expanded after the closure of the Huemul Project, and by the 1960s became larger in terms of size and expenditure than those in Bariloche. It was the Constituyentes research centre that the first Latin American research reactor was built (1957), the RA-1 Enrico Fermi. The 335-MWe Atucha I designed by Germany's (Siemens) was completed in 1974. In 1984 the 600-MWe Embalse designed by Canadian CANDU started its commercial operation. In 1995 CNEA's functions where divided into newly created separate organizations such as the Nuclear Regulatory Authority (''Autoridad Regulatoria Nuclear - ARN''), which supervises nuclear safety in the country, and the ''Nucleoeléctrica Argentina - NASA'', the company that operates the two completed nuclear power reactors. Today, CNEA mainly focuses on research and development of nuclear and related technologies. In 2001 the original 1956 Directory structure of a President and five members designated by the National Executive authority was reduced, eliminating four positions of the Directory by Decrees 1065/01 and 1066/01. On 2010 CNEA reopened the Enriched uranium plant at Pilcaniyeu inaugurated on 1983 〔(11 de noviembre de 1983: Anuncio del dominio de la tecnología de enriquecimiento de uranio por el método de difusión gaseosa desarrollado por la CNEA con la colaboración de la empresa INVAP S.E. en el Complejo Tecnológico Pilcaniyeu en la provincia de Río Negro. )〕 but closed in the 1990s 〔(Argentina To Produce Enriched Uranium In 2011 )〕 In 2014 692-MWe Atucha II, also a Siemens design, started operating besides Atucha I. Since then Argentina operates three pressurized heavy-water reactors (PHWR), that use heavy water as moderator and coolant and unenrciched natural uranium as fuel, for the generation of electricity. Also in 2014, CNEA begun construction of the world’s first small modular reactor (SMR), the CAREM-25 a small (25 MWe) pressurized water reactor (PWR) that unlike all previous power reactors in the country has been totally designed and developed domestically. It will use low-enrichment uranium as fuel and light water as coolant and moderator, a first for the country that traditionally used PHWRs designs.〔(【引用サイトリンク】 CAREM - Technical features )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「National Atomic Energy Commission」の詳細全文を読む スポンサード リンク
