the nuclear energy is a subject widely discussed all over the world. the nuclear accident of chernobyl and the goiania radiological accident contributed decisively to create a negative image of the nuclear area in the brazilian society. the operation of the angra 3 nuclear power plant, which is under construction, is linked to the construction of a radioactive wastes repository, what surely will be explored by the nuclear energy opponents. a big challenge for the professionals of the area in such constructions is not the engineering itself, but the public acceptance of the project, due to the great fear of the society in relation to this subject. the goal is to research and to show some international and national experiences about the public acceptance of nuclear enterprises are presented, giving focus on nuclear waste repositories where unsuccessful processes of public communication happened. it is important also to know such failures in order to not repeat them.
