The April 1997 National Law of Nuclear Activity assigns responsibility to the National Atomic Energy Commission CNEA (Comisión Nacional de Energía Atómica, founded in 1950) for radioactive waste management, and created a special fund for this purpose. Operating nuclear power plants pay into this. Awaiting final disposal interim storage of spent fuel takes place at cooling ponds on site, and some interim dry storage at Embalse.(*01) No reprocessing has taken place.

Final disposal
Final disposal of low-level waste takes place in engineering enhanced surface semi containment systems at the Ezeiza Radioactive Waste Management Area (AGE), operated by CNEA. For intermediate level wastes a monolithic near surface repository is foreseen, similar to those in operation in L’Aube, France and El Cabril, in Spain. (*02) Especially after a scandal in 2005 on high levels of water contamination with uranium in Ezeiza and Monte Grande, near the atomic center, doubts have risen about the conditions of and safety procedures at the AGE. The response from the CNEA and the government to the obvious contamination did not help to calm citizens’ worries, as it was marked by obscuring and silencing the real impact. A few years later the provincial government was forced to acknowledge the contamination values measured by independent laboratories, although official reports stated, that there was no contamination from nuclear waste but just high radioactive background level.(*03)

In 1994, during the nation’s constitutional reform, a broad Argentinean environmental movement won a momentous victory to make Article 41, which bans the import of toxic and radioactive waste, part of the national constitution.(*04)The Argentine Strategic Plan has provided three types of technological systems for final disposal:
– Engineered Surface System, for LLW requiring isolation periods of up to 50 years.
– Monolithic Near-Surface Repository, for ILW requiring isolation periods of up to 300 years.
– Deep Geological Repository, for HLW and SF requiring isolation periods in excess of 300 years.

With regard to spent fuel originating from research or radioisotope production reactors, the strategy considers two alternatives: Shipping them back to the country where they were originally enriched, if possible, or conditioning for final disposal.(*05)
The Strategic Plan, updated in March 2006, at present covers the period from 2006 through 2095. The deadline to adopt a decision on the possible reprocessing or final disposal of spent fuel is subject to the completion of the studies for the siting of the Deep Geological Repository which have to be concluded at the latest by 2030. At such time the installation of the underground geological laboratory must have been started, which allows the design and construction of a deep geological repository, which must be operative by the year 2060.(*06)
