The article describes a sociological problem linked to decision-making about the locality in which a deep geological repository of spent nuclear fuel and radioactive waste is to be built in the Czech Republic. The introduction explains the social situation of negotiations about the repository and identifies concerned stakeholders. The article then outlines the legal framework of the negotia-tions and summarizes their progress up to the present day. The rest of the article analyses data from two public opinion surveys. The first one surveyed the attitudes of citizens in selected locali-ties toward the project of the deep geological repository. The second survey investigated the atti-tudes of the Czech public toward radioactive waste and the deep geological repository.
