Abstract. The focus of the project is on how to regulate risky technologies, both old (such as nuclear waste management) and new (such as geoengineering). Thus, the project is aimed at contributing to a better understanding of the ethical, political, and socio-economic aspects of radioactive waste management-related risks. The goal of the project is to contribute to the current discussions on the case of the expansion of the Hungarian Nuclear Power Plant. The Paks II project allows us to present how to set up procedures where some radioactive waste-related risks will not derail decision-makers and how they can be held accountable by the public. The case of Paks II is also compelling; as of today there are only 19 countries in the world that are in the process of new reactor building (World Nuclear Association, 2021). The project is aimed at providing and defending a precautionary approach to radioactive waste management because it involves high levels of uncertainty and the possibility of causing irreversible harm on a global scale. When investigating procedural principles of radioactive waste management policies by three types of precautionary approaches, the project will look at risks that stem from the displacement of politics in public consultations in relation to large infrastructural projects. The practices of the emerging era of public engagement tap into the current debates on democratic politics in political theory with the emergence of deliberative democracy (Bohman and Rehg, 1997; Dryzek, 2000; Gutmann and Thompson, 2009), and radical democracy (Laclau and Mouffe, 2001; Mouffe, 1999, 2000). Specific attention will be paid to the fragmentation of public along with technical and non-technical, local and national, site-specific and general issues, and the role of different political platforms (public exhibition events, consultation documents, and public engagement sessions) in the way in which the political is displaced from the arena of public inquiries to legal challenges and debates about boundaries and geographies.
