When a country becomes self-sufficient in part of the nuclear cycle, as production of fuel that will be used in nuclear power plants for energy generation, it is necessary to pay attention for the best method of storing the spent fuel. Temporary storage of spent nuclear fuel is a necessary practice and is applied nowadays all over the world, so much in countries that have not been defined their plan for a definitive repository, as well for those that already put in practice such storage form. There are two main aspects that involve the spent fuels: one regarding the spent nuclear fuel storage intended to reprocessing and the other in which the spent fuel will be sent for final deposition when the definitive place is defined, correctly located, appropriately characterized as to several technical aspects, and licentiate. This last aspect can involve decades of studies because of the technical and normative definitions at a given country. In Brazil, the interest is linked with the storage of spent fuels that won't be reprocessed. This work analyses possible types of storage, the international panorama and a proposal for future construction of a spent nuclear fuel temporary storage place in the country.

poder desenvolver meu trabalho de doutorado. Ao Centro Tecnológico da Marinha em São Paulo (CTMSP), pelo incentivo na realização do doutorado. Ao Centro de Desenvolvimento de Tecnologia Nuclear (CDTN), pela oportunidade de participação em testes em protótipos de cascos para combustível nuclear. À Profa. Dra. Barbara Maria Rzyski, pela valiosa orientação, ensinamentos, incentivo e amizade em todos os momentos necessários desde a época da realização do mestrado, sem o que não seria possível realizar este trabalho. Aos meus pais, Walter e Leonite, que proporcionaram os primeiros passos rumo ao saber e ao estudo. À minha esposa Mônica e ao meu filho Allan, pela compreensão e apoio neste período.
