Abstract (EN): This chapter introduces the role of engineered clay barriers in multibarrier systems in the control of radioactive contamination from nuclear waste, which is an imperative challenge nowadays. Currently the electricity demand is increasing rapidly, whereas the CO2 concentration in the atmosphere is reaching a critical level. In this regard, nuclear energy has aroused particular interest, once it is the only energy source that may suppress, at the same time, the world¿s growing energy needs and the carbon emissions. Nevertheless, one major concern related to nuclear power is the generation of radioactive wastes, which are disposed in specific landfills and require specialized management. The nature of these hazardous wastes, the main sources of radioactive contamination, the adsorption mechanisms involved in the interaction contaminant/clay mineral, and the role of clay barrier systems in the containment process are discussed in this chapter.
