Resumo


The choice of candidates sites for final disposal of high-level radioactive wastes has been a complicated process worldwide, mainly due to the complexity of the environments that are adequate to receive this type of repositories, whose disposal may have several implications related to environmental impacts, as well as in a set of issues associated to the geographical dynamics of these regions. In the Brazilian case, where the nuclear program includes the operation of two nuclear power plants and a third unity under construction, the concern with the high-level nuclear waste is still in its infancy. However, it is important that studies be discussed and started,including the development of methodologies that can contribute to the implementation of policies, rules and specific regulations, in order to facilitate an action planning for the solution of this problem. This article will show part of the studies that are being conducted by some Brazilian Nuclear Energy Commission (CNEN) experts together with some professors from the State University of Rio de Janeiro (UERJ), regarding site selection of deposits for high-level radioactive waste in the state of Rio de Janeiro. The work will focus, especially, on geological repositoriesaimed for the safe disposal of the high-level radioactive waste produced mainly by the Brazilian nuclear plants Angra 1, 2 and 3 located in the state.This article will also point out the main aspects involved on the technical choice process necessary for this kind of deposits, including the present stage of research for the development of a database, based on a geographic information system (GIS). This GIS system will containtechnical information to support the decision making process of site selection, establishing geo-environmental guidelines including the development of a specific methodology for site selection.
