Abstract: Located in the south-eastern mountains of Anina the uranium mining exploitation Ciudanoviţa, opened in 1950 by Sovrom-Kvarţit mining company, represents the cause of a long term process of environmental degradation with direct and indirect influences on all components of the environment, but especially on local human population. Following mining operations, there are extensive areas of land occupied by waste dumps containing radioactive material, derived from opening, preparation and exploitation works of uranium deposits. These dumps generate significant risk of contamination by radiations, as well as a high potential for environmental pollution. The purpose of this paper is to design a series of ecological reconstruction works of the waste dumps in the area, namely Natra waste dump. In order to achieve the goal there were established several objectives, including: studies on the chemical and physical stability of the dump, redesigning measures to avoid the occurrence of landslides, the containment of radioactive material in relation to the biosphere, the level of intervention and the appropriate reuse of the land. Given the severity of the negative effects on the environment caused by radioactive emissions, even in the case of relatively low intensities, isolation and ecological reconstruction of such waste dumps is not only appropriate, but mandatory.
